Mineralization of Phenanthrene by Paenibacillus sp. PRNK-6: Effect of Synthetic Surfactants on its Mineralization
type: item
description: Paenibacillus sp. PRNK-6 isolated from a soil contaminated with polycyclic aromatic hydrocarbons (PAHs) was able to utilize 69.48% of phenanthrene (320 mg l-1) in 48 h. The effect of three synthetic surfactants namely, the nonionic surfactant Tween-80, the anionic surfactant sodium dodecyl sulphate (SDS) and the cationic surfactant cetyltrymethyl ammonium bromide (CTAB) on the phenanthrene mineralization by Paenibacillus sp. PRNK-6 was studied. Results showed that the effect of each surfactant on phenanthrene mineralization by PRNK-6 and serve as growth substrate varied considerably. Tween-80, at the concentration of 1.5%, enhanced the growth and mineralization of phenanthrene from 69.48% to 90%; whereas SDS and CTAB, have a negative effect on the growth and mineralization of phenanthrene by Paenibacillus sp.

A Study for the Presence of Enterococcal Virulence Factors Gelatinase, Haemolysin among Clinical Isolates in a Tertiary Care Hospital
type: item
description: Enterococcus, considered a normal commensal of intestinal tract, is fast emerging pathogen causing serious infection. Despite the increasing importance of Enterococcus as opportunistic pathogens, their virulence factors are still poorly understood. The potential virulence factors of Enterococci include production of enterococcal surface protein (Esp), gelatinase, and haemolysin. Gelatinase- and haemolysin-producing strains of Enterococcus faecalis have been shown to be virulent in animal models of enterococcal infections. This study was undertaken to determine the prevalence of virulence factors (gelatinase and haemolysin), phenotypically and correlation between virulence factors with respect to different clinical specimens.

Incidence of Community acquired MRSA in the nasal swabs of general population of Gulbarga region
type: item
description: Background: Methicillin resistant S. aureus (MRSA) has emerged as a major pathogen in both community and hospital settings. Nasal carriage of S. aureus represents a major risk factor for the development of infection with this bacterium. Objective: The aim was to study community acquired MRSA incidence among nasal swabs of general population of Gulbarga. Methods: Nasal swabs from anterior nares were collected for the isolation of S. aureus from 224 individuals including Microbiology Department students and general population of Kusnoor village in Gulbarga region, Karnataka. The nasal swabs were enriched in nutrient broth for enrichment of S. aureus then streaked on Mannitol Salt Agar (MSA) and incubated at 37 °C for 24 hours. Conventional methods such as growth characteristics on mannitol salt agar, Gram’s staining, and biochemical characteristics have been performed for characterization of the S. aureus. Antibiotic sensitivity test was carried out for the isolated S. aureus using different antibiotics. Results: A total of 224 nasal swabs were screened and the incidence of S. aureus was observed to be 41.96% (94/224). Of the total 94 S. aureus isolates, 1 (1.06%) isolate was found to be MRSA and 93(98.93%) isolates were MSSA. A total of 3 (3.22%) S. aureus isolates were found to be multi-drug resistant (MDR) in this study. Conclusion: Our results suggest that general populations are at risk and are potential carriers of S. aureus and in particular MRSA.

Antimicrobial Susceptibility Profile of Airborne Bacteria and Fungi at Owena Market, Osun State, Nigeria
type: item
description: Environmental conditions and human activities influence the ubiquity and diversity of microorganisms in the atmosphere thereby acquiring the ability to resist antibiotics which poses serious public threat. Airborne bacteria and fungi isolated using settling plate method from three different points (where kolanuts, meat and onions are sold) at Owena Market, Osun state, Nigeria were assayed for antimicrobial susceptibility using disc diffusion. The microorganisms were identified as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Proteus vulgaris, Bacillus megaterium, Alcaligenes spp., Aeromonas spp., Escherichia coli, Micrococcus spp., Streptococcus spp., Mortierella polycephala, Epicoccum nigrum, Alternaria spp., Penicillium chrysogenum, Aspergillus flavus, Acremonium spp., Penicillium oxalicum, Cladosporium cladosporiodes, Rhizopus stolonifer, Stemphylium spp., and Trichoderma spp. About 30% of the bacterial isolates were resistant to the antibacterial agents (antibiotics) and all the bacterial isolates were resistant to at least four or more antibiotics while 18% and 64% of the fungi isolated were susceptible to griseofulvin and ketoconazole, respectively. This study shows that the market environment serves as reservoirs for multiple antibiotic resistant bacteria and fungi capable of causing infectious diseases.

Changes in Physicochemical, Biochemical and Microbiological Quality Parameters of Green and Black Tea during Storage
type: item
description: The shelf life of different packaged tea is very important concern of tea industry. The aluminium packaging is better than any other packaging to determine best before use. Thus different times are applicable for both green and black tea to keep their physicochemical, biochemical and microbiological parameters. The rate decrease of quality parameters (according to FSSAI regulation) are higher in Green tea (sharp changes started from 3 rd months) than Black tea (gradual changes) in control packs but well protected till 12months with aluminium and silica packs. Majority of Black Tea quality parameters are well protected upto 15th month in silica and aluminium, but on an average the stability is upto 14 th month, whereas in control (without silica) packs it is well upto around 11 months on an average, so Black tea is best before use 14th month. After that remarkable reduction in antioxidant and antimicrobial properties are decreased. Tannin contents are also decreased. For green tea taking all the parameters concerned (including antioxidant and antimicrobial potential) 12 months (on average) is threshold point for best before use with aluminium and silica, whereas the control packs are stable upto 7 to 8 months (on average).In both the cases the aluminium and silica is best packaging material to keep nutritional parameters intact.

Phenotypic detection of ESBL production in Escherichia coli isolated from UTI patients of Kalaburagi city, Karnataka, India
type: item
description: Aim: The principle aim of present conducted study was phenotypic detection of extended spectrum ß-lactamase (ESBL) production in Escherichia coli strains isolated from urinary tract infected patients of Kalaburagi city, Karnataka, India. Materials and Methods: The positive E. coli isolates selected for the following study was isolated from urine sample of UTI patients. The screening of positive E. coli was done and antibiotic susceptibility test and MIC were determined as per CLSI guidelines. Phenotypic detection of ESBL production in E. coli isolates was determined by combination disk method and double disc synergy test. The positive ESBL production was determined based on the zone of inhibition by comparing with standard CLSI guidelines. Results: Among 285 E. coli isolates, 268 (94.03%) isolates were multidrug resistant. Among 268 MDR E. coli isolates, 247(92.16 %) isolates were resistant to cephalosporins. Every 247 cephalosporin resistant E. coli isolates have shown high level of MIC range of ≤256 µg/ml. Among 247 E. coli isolates, 187 (75.70%) isolates were positive for ESBL production. Among 187 positive ESBL, 67 (35.8%) were cefetoxime-mediated ESBL producers, 78 (41.71%) E. coli isolates were ceftazidime-mediated ESBL producers and subsequently 52 (27.8%) were ceftriaxone-mediated ESBL producers. Conclusion: The outcome of the present study, increased incidence of ESBL producing E. coli causes UTI, in hospitals and the E. coli isolates were MDR and responsible for ESBL production against majority of cephalosporin group of antibiotics, preferentially used for the treatment of gram negative bacterial infections.

Application of Probiotic Diet on Rats and its Effect on Lipid Profile: A Case-control Study
type: item
description: Lipid profile and cholesterol level play an important role in cardiovascular and other life style diseases. A case-control study was designed on 16 rats to observe the effects of probiotic diet for controlling lipid and cholesterol level. Probiotic bacteria culture (Danisco freeze drying culture) was collected from Denmark. The isolation and identification of the strains was carried out at Industrial Food Microbiology laboratory, Institute of Food science and Technology of BCSIR, Dhaka. In cases group, eight rats were fed high fat diet for 7 days and then collected blood sample for lipid profile analysis. Probiotic diet was fed from day 8 to another 7 days and at day 15, again collected blood sample. In control group, another eight rats were fed normal laboratory diet and after 15 days, collected blood sample. Comparing the effects of probiotic diet the cases rats of probiotic diet group curtly reduced the LDL, TC, TG and increased the HDL. Lactobacillus acidophilus and bifidobacteria’s presence in probiotic diets probably is responsible for decrease the total cholesterol up to 92 mg/dl, triglycerides up to 21 mg/dl, LDL up to 15 mg/dl and increased HDL up to 60 mg/dl. On the other hand, fat diet and control diet does not have any significant changes their lipid profile. Thus, it can be postulated that probiotic diet can be a healthy diet for rats or even human beings.

Analysis for Respiratory Transmittable Diseases via Mass Spectrometry
type: item
description: Microbial identification in clinical diagnostic laboratories has mainly relied on conventional phenotypic and gene sequencing identification techniques. The development of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) devices has revolutionized the repetitive identification of microorganisms in clinical microbiology laboratories by introducing an easy, rapid, high throughput, low-cost, and effective identification technique. This technology has been modified to the restraint of clinical diagnostic laboratories and has likely to replace or complement conventional identification techniques for both bacterial and fungal strains. In recent advances of MALDI-TOF-MS as the laboratory diagnostic tool for the rapid laboratory diagnosis of microorganisms associated with respiratory infectious diseases, with the focus on rapid identiï¬cation of pathogenic bacteria and molecular markers discovery using MALDI-TOF-MS. With the advanced technologies such as MALDI-TOF, early and targeted therapies are based on rapid identification of pathogens and could lead to quick and effective treatment of respiratory infections and better patient management.

Biochemical Characterization of Mutant Strains and Cloning of Lactate Dehydrogenase Gene from Staphylococcus aureus
type: item
description: An infection is the detrimental colonization of a host organism by a foreign species. About 15 million (>25%) of 57 million annual deaths worldwide are estimated to be related directly to infectious diseases. The burden of morbidity (ill health) and mortality associated with infectious diseases falls most heavily on people in developing countries and particularly on infants and children diseases. Infectious diseases are the second leading cause of death; the leading cause of disability-adjusted life years worldwide; and the third leading cause of death in the United States. Among infectious diseases which are causing death worldwide, acute lower respiratory tract infections (24%), HIV/ acquired immunodeficiency syndrome (AIDS) (23%), diarrheal diseases (17%), tuberculosis (9%), and malaria (12%) are predominant.

Bacteriological and Yeast Profile in Clinical Samples from Immunocompromised Persons (Especially in HIV and Cancer Patients) and Their Antimicrobial Susceptibility Pattern
type: item
description: Abstract Immunocompromised host describes a patient who is on increased risk to acquire infection due to congenital or acquired abnormality of the immune system. In the past few decades, the population of immunocompromised hosts has expanded enormously, due to the increased use of immunosuppressive conditions like HIV, cancer, etc. This study was planned to know the spectrum of organisms and trend of antimicrobial susceptibility pattern in immunocompromised patients. All hospitalized patients of Maharao Bhim Singh (MBS) Hospital, JK Lone Hospital and New Medical College Hospital, Government Medical College, Kota, Rajasthan, undergoing anticancer therapy, radiotherapy or recently diagnosed cancer patients and HIV patients attending anti-retroviral therapy (ART) centre for highly active anti-retroviral therapy (HAART) are included. From 100 patients, 130 specimens were collected under strict aseptic precautions. Then specimens were transported to the microbiology laboratory. It was observed that immunocompromised patients with opportunistic infection were more common in males and in 25–50 year age group. Among gram-positive bacteria, Vancomycin, Linezolid, Amikacin and Azithromycin were most effective (100% Sensitive) drugs. Among gram-negative bacteria, Imipenem was found most effective antibiotic followed by Azithromycin, Levofloxacin and Piperacillin/Tazobactam. Among Candida species, Amphotericin B was found most effective antifungal among immunocompromised patients. Maximum numbers of samples were collected from age group 26–50 years (63 samples, 48.46%). Among 130 samples, 113 samples (86.92%) showed positive result in culture (yeast, GPC, GNB) and microscopy (MTB). Mycobacterium tuberculosis (MTB) was detected only in HIV positive patients; that is 53.24%. The yeast was predominant isolate among immunocompromised patients, which may be due to prolonged use of antibiotics and prolonged stay in hospital.

A Cross-Sectional Study on Prevalence and Seasonal Trends of Malaria and Dengue and Their Co-infection in Patients with Acute Febrile Illness Attending a Tertiary Care Hospital in Jhalawar, Rajasthan
type: item
description: Unknown etiologies behind acute febrile illnesses make treatment choices tough for clinicians resulting high mortality rates amongst the vulnerable populations. Vector borne diseases viz. malaria and dengue are the major stake holders responsible for AFI. Determination of their individual as well as concurrent prevalence is important for disease control. The present study aimed to determine the prevalence and seasonality of malaria and dengue and their co infection in acute undifferentiated febrile patients. The study was performed on samples of patients presenting with fever of less than 15 days duration at the department of microbiology, Jhalawar Medical College, Rajasthan during January–December 2016. The samples were tested for malaria (Peripheral Blood film examination using Giemsa staining and Quantitative Buffy Coat (QBC) examination) and dengue (MAC ELISA). The study included 1059 patients (age 1–85 years) with acute febrile illness, and prescribe for malaria investigations. 58 (5.48%) patients were diagnosed positive for malaria. Of these, 27.58% (16/58) were positive for P. vivax, 70.68% (41/58) had P falciparum infection while one patient was having mixed infection with P falciparum and P vivax. Of 493 patients tested for Dengue IgM antibodies, 60.24% (299) were positive and two patients were equivocal. It was concluded that dengue and malaria are common etiological agents responsible for acute febrile illness in patients particularly in the monsoon and post monsoon season in our region. With the use of appropriate diagnostic methods, the exact disease burden can be estimated and timely management of the patients can be ensured.

Diagnostic Methods for Hepatitis-C Virus and Tuberculosis Coinfection among HIV Infected Individuals: A Review
type: item
description: HIV is the chronic viral infection documented worldwide. HIV virus infects and destroys helper T cells (CD4) leading to a number of immunological deficiencies among which Hepatitis-C Virus (HCV) and Tuberculosis (TB) are the major. HCV is a RNA virus that infects the liver leading to cirrhosis, hepatocellular carcinoma and is a leading cause of deaths in HIV/HCV co-infected patients. Tuberculosis, the most common opportunistic infection in HIV positive patients, affects mainly lungs and is transmitted exogenously. HIV and HCV have similar routes of transmission via blood and blood products, sexual contact, IV drug users and vertical transmission. Tuberculosis (TB) is transmitted through aerosol exposure as well as transplacentally. About 30% of HIV-positive individuals are co-infected with HCV worldwide. The sample for HCV detection can be blood and that for tuberculosis, can be both blood and sputum. The diagnosis of HCV in HIV patients can be done by ELISA and kit methods. Similarly diagnosis of tuberculosis can be done by AFB staining, fluorescence microscopy, by culturing in Lowenstein Jensen media, ELISA test as well as by Mantoux test. Since HCV and tuberculosis are the major co-infections among HIV infected individuals, there requires the accurate, specific and rapid tests that can be carried out in routine laboratory procedures.

A Need of a Novel Antimicrobial Suture for Surgical Site Infection
type: item
description: Surgical site infections post-surgery are the major complications that lead to the patient’s longer hospitalization which directly increases treatment cost. Triclosan is an antibacterial agent which has been used in coating surgical sutures to prevent infection post-surgery. Triclosan is being used since many years in many consumer products; the bacterial strains which are emerging these days may slow down or get resistance of their effects which might lead to the serious consequences in the future. Some studies suggest that since triclosan is an antiseptic agent, there is no chance for microbes to get resistance against it. But several studies strongly recommend that since this agent has been used since long times there might be some bacterial strain which can get resistance. In this paper, we will try to give the views of different authors working on antibacterial sutures and come up to a conclusion whether we really are in need of a promising suture (antibacterial) for surgical site infection which could reduce infection after surgery. In this article, our main objective is to study whether a novel antimicrobial agent is required to prevent surgical site infection post operation.

Assessment of Microbial Quality of Irrigated Cabbage with Wastewater in Laelay Maychew and Tahtay Maychew Woreda’s of Aksum, Tigrai, North Ethiopia
type: item
description: <!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:RelyOnVML /> <o:AllowPNG /> </o:OfficeDocumentSettings> </xml><![endif]--> Wastewater can be defined as water that has been badly affected in quality by anthropogenic effect and the possible origin can be from domestic, industrial, commercial or agricultural activities, surface run off or storm water and from drain inflow or infiltration. Quality of water and other food can be checked by the presence of Coliform bacteria because these bacteria are the predominant indicators. The purpose of this study was to determine the microbial quality of irrigated cabbage with wastewater in Laelay Maychew and Tahtay Maychaw woredas of Aksum by checking the Coliform bacteria’s load as the farmers use wastewater for irrigation to cultivate different vegetables. A total of four samples were taken randomly using glass bottle and 11.05x108cfu/m/ of coli form was isolated using MacConkey Agar. Samples were directly transported to Aksum university department of biology laboratory and processed within five hours. Eosin, methylene blue agar Levine (EMB), MacConkey Agar was used for the detection of the samples. Descriptive statistics were used to describe the data. 100% of the irrigated cabbage were positive for coliform bacteria. Typically, the non-lactose fermenter gram negative coliform bacteria such as Citrobacter and Hafnia. Both were appeared as colorless on MacConkey Agar. A total of 9.7x 106cfu/ml coliform bacteria form two samples that were collected from Laelay Maychew woreda Sofho Keble and 10.77x107cfu/ml from two samples of Tahtay Maychew woreda Ade’eko kebele. A minimum of 2.8x105cfu/ml and maximum of 6.2 x 106cfu/ml coliform bacteria were recorded. The study has confirmed high bacterial load on the irrigated cabbage, so it needs further investigation for specific microbial identification and water treatment should be applied.

DON has also been demonstrated to inhibit the replication of poliovirus, respiratory syncytial virus, mumps, and herpes simplex virus in cultured eukaryotic cells. DON is an analogue of glutamine and inhibits the synthesis of glycoproteins and purine nucleotides in cells that are treated with the antibiotic. DON inhibits the aminotransferase enzyme that uses the amino group of glutamine to construct the precursor molecules of nucleotides and to convert fructose-6-phosphate into glucosamine for glycoprotein synthesis. DON does not inhibit the enzyme activity of Buffalo green monkey kidney (BGMK) cells at concentrations as high as 2,500 µg/ml. At a concentration of 5 µg/ml, DON inhibits the replication of adenovirus in BG…

Physicochemical, Biochemical and Microbiological Characterization of Green and Black Tea during Storage in Different Packaging Materials
type: item
description: The storage of tea is an important endeavor for tea industry. The appealing characteristics of this beverage are its aroma, taste, color as well as its antioxidant and antimicrobial qualities. The different manufacturing strategies for black and green tea affect the shelf life of different types of commercially available tea varieties. Different types of packaging alter the quality parameters of different tea clones. The quality parameters are assessed according to the Food Safety and Standards Authority of India (FSSAI) parameters. Green tea is superior with respect to physico- chemical, biochemical, microbiological parameters at the fresh/unstored condition than black tea but it is found that the rate of change in physicochemical properties such as ash content, moisture content, crude fat, crude fiber, crude protein are much higher (% reduction is higher) than that of the black tea samples. The biochemical quality parameters (flavonoid, caffeine, amino acid, antioxidant potentials, theaflavin, thearubigin, total catechins, total tannins etc.), and microbiological parameters (antimicrobial activities—growth inhibition in solid and liquid medium, growth of microorganisms in aqueous solutions of different tea) are also reduced in higher percentage in green tea. It is pertinent to mention here that the aluminum packaging with silica desiccants renders better protection against storage-related deterioration of tea quality parameters.

Study of Aerobic and Anaerobic Bacteriological Profile in Patients Presenting with Ear Discharge and Antimicrobial Susceptibility Pattern of Aerobic Isolates
type: item
description: Ear discharge is a major health problem in both, developed and developing countries. This study was undertaken to determine the pattern of the different etiological aerobic and anaerobic bacteria in patients presenting with ear discharge and clinically diagnosed as CSOM and ASOM and also to know the antibiogram of aerobic bacteria in Kota Rajasthan. A prospective study was carried out in department of microbiology, MBS Hospital, Kota, among 100 patients attending the ENT OPD over a period of 12 months. Informed consent was obtained from the patients for this study and microbiological analysis was done. Ear swabs were taken from 100 patients. Total 108 swabs were collected as some patients presented with bilateral ear discharge, the total number of bacterial isolates were 109 as some swabs showed polymicrobial growth and six cases were sterile. Gram-negative bacteria were the dominant isolates (69.20%) while gram-positive bacteria were 32 (30.76%). The most common isolate overall among both the CSOM and ASOM was Pseudomonas aeruginosa (42.20%), followed by Staphylococcus aureus (27.52%), Proteus spp. (10.09%), Klebsiella spp. (6.42%), Escherichia coli (4.58%), Acinetobacter spp. (2.75%), Enterococcus spp. (1.83%), CONS (1.83%), Anaerobic gram-negative bacilli (1.83%) and anaerobic Gram-positive cocci (0.91%). Pseudomonas aeruginosa showed high-level resistance to antimicrobials. Least resistance was found for Amikacin, Ceftazidime, Imipenem, and Piperacillin/Tazobactam among gram-negative organisms and hence could be used for empirical therapy. Vancomycin (100%), Linezolid (100%) and Clindamycin (70%) were found to be most sensitive drugs for gram-positive organisms.

Diagnosis of Dengue by NS1 Detection: Comparison of Rapid Immunochromatography versus ELISA Kits
type: item
description: Dengue is an acute infectious disease of viral etiology. It is probably one of the most important arthropod borne viral disease in terms of human morbidity and mortality. The spectrum of disease ranges from self-limited dengue fever to more severe forms of dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). So, to reduce mortality and morbidity early and accurate diagnosis of dengue is essential. Study assessed comparison of currently available rapid test for NS1, IgG, and IgM combo kit and conventional dengue Ag ELISA test (CTK Biotech) ELISA kit. The performance of rapid kit RICT (Dengue Day 1 Test; J. Mitra) is quite satisfactory as sensitivity of test as compared to ELISA test was 94.44%. Regarding specificity, with reference to dengue Ag ELISA test (CTK Biotech), the specificity of RICT (Dengue Day 1 test; J. Mitra) was 71.43%. The use of combination kit helps to detect additional cases of dengue, which are negative for NS1 antigen but positive for IgM and/or IgG antibodies, thus facilitating early diagnosis in remote areas and small laboratories.

Bacteriological Profile and Antibiogram Pattern in Lower Respiratory Tract Infection in Kota Region (Raj)
type: item
description: Lower respiratory tract infections are the most frequent infections among patients. The consequences on increased drug resistance are far reaching, since bacterial infection of the lower respiratory tract is a major cause of death from infections disease. This study was focused on obtaining a comprehensive insight into the microbial profile, its prevalence and the antibiotic susceptibility patterns of the isolates in lower respiratory tract infections. Sputum specimens were collected from 1800 patients of all the age and sex groups with symptoms of LRTIs. Following culture, the isolated organisms were identified and antimicrobial sensitivity was performed by standard methods. Out of the 1800 sputum culture samples, significant pathogens were isolated in 546 sputum samples. Male (n=380) were found to be more at risk to LRTIs then females (n=166). LRTIs were found more prevalent in 60 years or older age groups. K. pneumoniae (25.30%) was the commonest pathogen isolated, followed by Pseudomonas aeroginosa (21.80%), Staphylococcus aureus (20.14%), Streptococcus pyogenes (9.90%), E. coli (8.24%), Candida albicans (7.90%), Acinetobacter species (4.39%), Citrobacter species (1.46%), Enterobacter species (0.54%) and Proteus species (0.33%). Gram positive organisms showed 90–100% susceptibility to Vancomycin, Levofloxacin, Amikacin and Linezolid; while majority of gram negative organisms had high susceptibility to piperacillin tazobactam, imipenam, cefoperazone/sulbactum, amikacin, and ceftazidimie/tazobactam. The emergence of resistant strains poses a major threat to the patients, globally. The reason for the resistance may be due to indiscriminate use and abuse of drugs, adulteration of drugs and mutation of microorganisms. Before starting empirical antibiotics on patients with moderate to severe lower respiratory tract infections, it is always advisable to obtain sputum for culture and antibiotic sensitivity test. So, inappropriate and irrational drug usage can be avoided…

type: item
description: Malaria is caused from infection by the protozoa of plasmodium. It is one of the serious diseases. There are four species of plasmodium infecting humans; these are Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malaria. The main point of the study of malaria tosses the distribution and prevalence of P. falciparum and P. vivax species in and around Tepi town in the year 2003 and 2004 E.C. The secondary data was taken from the patients diagnosed with malaria at the Tepi Health Center in the year 2003 and 2004 E.C. The age group was ranged as 0–18 years, 19–30 years, 31–60 years and above 60 years and the percentage of infected peoples in each age ranges was calculated. Finally the chart was obtained using MS-Excel tools. The highest distribution of P. falciparum was found for the age range of 19–30 years and 0–18 years in the year 2003 & 2004 E.C., respectively; whereas for P. vivax, the highest distribution was obtained in the age range of 0–18 years and 19–30 years in the year 2003 & 2004 E.C., respectively. On the other hand, the lowest distribution of both P. falciparum and P. vivax was found for the age range of above 60 years old in the year 2003 and 2004 E.C. Generally, it was concluded that, most of people living in and around Tepi town were highly infected with of P. vivax as compared to P. falciparum in the year 2003 E.C.
