Abstract: The MPB64 protein of Mycobacterium tuberculosis (M.tb) is an important structural and functional protein, which has been known to be involved in the virulence, pathogenesis as well as proliferation of the pathogen, however, how MPB64 protein interaction with host protein is still unclear. To identify cellular proteins that interact with the MPB64 protein and to elucidate the possible involvement of MPB64 protein in M.tb pathogenesis, a human lung cDNA library was screened using a yeast two- hybrid system assay. HSP…

Abstract: Pogostemon parviflorus, an aromatic woody herbaceous plant, is found in high rainfall localities. The medicinal properties of this plant show that leaves are used for anxiety, cellulite, depression, eczema and wounds. Also, they are used for thrush, mycotic enteritis and vaginitis. The aim of the present study is to assay the anti-Candida activity of the ethanolic and methanolic extracts of Pogostemon parviflorus leaf against opportunistic mycosis causing phatogenic fungi, such as Candida albicans (5), Candida glab…

Abstract: The maintenance of fungi isolates and the development of methodologies were available from their phenotypic and genotypic characteristics. Alterations of Histoplasma capsulatum and Candida spp. Strains preserved by continuous subculturing on fungal collection and by lyophilization for 35 years were evaluated. Candida isolates maintained by lyophilized methodology were viable and preserved by the typical characteristics of each species. Only one lyophilized isolate from H. capsulatum was viable and demonstrated typi…

Abstract: The crude methanol extract of the whole plant of Cestrum nocturnum L. (Solanaceae) and its subsequent fractions were tested against various bacterial and fungal strains. With the exception of Salmonella typhi, the tested samples showed marked antibacterial activity against Pseudomonas aeruginosa, Staphylococcus aurous, Bacillus subtilis, Escherichia coli and Shigella flexenari. The minimum inhibitory concentrations (MICs) ranged from 19 to 280 µg/ml. The crude extract and fractions were also susceptible to Candida…

Abstract: In this study, the genetic variation in Karakul sheep was investigated using 15 microsatellite markers (MCMA2, BMS460, BM1815, OARCP26, OARFCB20, MAF64, OARAE129, BMS332, LSCV38, BM6444, BMS995, MCMA26, BMS678 and OARCP49) and all fifteen loci were amplified successfully. Genomic DNA was extracted from 120 blood samples, using modified salting-out method. Tests of genotype frequencies for deviation from the Hardy-Weinberg equilibrium (HWE) were performed at each locus and revealed significant departure from HWE (P…

Abstract: The importance of medicinal plants in traditional healthcare practices provides opportunity to new areas of research. However, information on the uses of plants for medicine is lacking from many interior areas of District Mansehra. Keeping this in view, the present study was initiated. This study attempts to shade lights on the comparative pharmacological efficacy of Berberis lycium (medicinal plant) and drug penicillin G. The pharmacological activities of both the B. lycium and penicillin G were determined by disc…

Abstract: Antigen screening were conducted to stool samples from 60 patients admitted to our emergency department with diarrhea complaint between June 2009 and October 2009 by the methods of direct microscopic examination, trichrome staining, ELISA (Enzyme-linked immunosorbent assay), respectively. As a result of examination of total 60 samples with direct microscopic, trichrome staining and ELISA method, it was detected positive in 7(11.3%), 6(9.7%) and 8(12.9%) samples, respectively. The presence of Entamoeba histolytica h…

Abstract: The present study deals with the antimicrobial activity of the aqueous, acetone and petroleum ether extracts of the leaves, stem and root of Andrographis ovata Clarke, Aristolochia indica L., Eclipta prostrata L. and Gloriosa superba L., using agar diffusion method against human pathogens, such as Escherichia coli, Proteus vulgaris, Psudeomonas aeruginosa and Klebsiella pneumoniae. In the present investigation, all the extracts were found to be effective against four human bacterial species, E. coli, P. vulgaris, P…

Abstract: Red ginger (Zingiber officinale Roscoe) a well known herb that was widely used as a remedy for various ailments in traditional medicine, belonged to the Zingiberaceae family. The red ginger had antibacterial properties. In the face of increasing bacterial resistance to various antibiotics and continuous efforts to look for new and safer antibacterial substances, the objective of this study was to assess the red ginger’s antibacterial potentials for treating-mastitis. Mastitis was a common milking cows’ disease that…

Abstract: The aim of this study was to determine the inhibitive effect of 25 Lactobacillus delbruecki ssp. bulgaricus and 16 Streptococcus thermophilus strains isolated from 30 different homemade yoghurts on several pathogen and contaminant bacteria. The antibiotic resistance of these bacteria was also determined. All of Lactobacillus bulgaricus strains exhibited antimicrobial activity against Escherichia coli, whereas all of S. thermophilus strains exhibited the same activity against Klebsiella pneumoniae. None of L. bulgar…

Abstract: Urinary tract infections (UTIs) occur frequently among women with diabetes. The present study aimed at determining prevalence and risk factors of bacteriuria in diabetic women and antimicrobial resistance pattern of the isolates at Muhimbili National Hospital (MNH), Dar es Salaam. Three hundred diabetic women attending clinic at MNH from June to November 2010 were included in the study. Demographic and clinical information were collected using a structured questionnaire. Urine specimens were collected for urinalysi…

Abstract: This study was carried out with the aim of identifying bacterial species involved in lung lesions of camels slaughtered between October 2009 and April 2010 at Addis Ababa abattoir enterprise, Ethiopia. All camels were originated from Borana and Kereyu pastoral areas. A total of 387 lungs were inspected during the study period, of which 300 (77.5%) possessed gross pulmonary lesions. Of which 72 lungs with lesions were processed for bacteriology and bacterial growth was observed from 50 of the pneumonic lung samples…

Abstract: Dermatophilus congolensis is the causative agent of dermatophilosis an economically important disease of livestock, and also an agent of zoonotic importance. The disease has been reported worldwide, with a wide host range which includes domestic, wild and aquatic animals. This study was therefore undertaken to characterize isolates of the organism from cattle, sheep and goats in Nigeria. All the isolates, except two sheep isolates fermented glucose and sucrose. The whole cell protein profiles of the isolates were s…

Abstract: Thirteen metal-tolerant bacteria capable of producing metal- removing bioflocculants were isolated from an industrial effluent sample. Pseudomonas sp. was found to be the pre-dominant species among the isolates (8 out of 13), followed by Herbaspirillium spp. (4) and one Paenibacillus sp. The flocculating activity of bioflocculants produced by these microorganisms was assayed using the kaolin clay. The heavy-metal-removal efficiency was determined using atomic absorption spectrometer before and after mixing the biof…

Abstract: Nosocomial infections are one of the occupational biohazards that affect the health of individuals with or without predisposing factors. Staphylococcus aureus is associated with significantly higher mortality and is associated with community-acquired serious nosocomial infections because strains generally show multiple drug resistance, which limits treatment possibilities. A total of 1800 patients in the state of Andhra Pradesh were screened for the presence of Staphylococcus species and were tested for antibiotic…
