Abstract: Seven hundred and eighty (780) female students residing in the campus of the University of Ado Ekiti were examined for significant bacteria indicative of urinary tract infections. Analysis of their clean-voided, midstream urine revealed that 507 (65%) female students have significant bacteria, 146 (18.75%) indicated insignificant bacteria while 127 (16.25%) showed no growth. Fifty eight (58) bacterial isolates were obtained from samples positive for bacteria. 8 (13.8%) were sensitive to streptomycin, 7 (12.1%) to t…

Abstract: Due to rapid development of resistance and high cost of the new generation antibiotics, lots of efforts are being made to discover new antimicrobial agents from different sources. In the current study aqueous and hydro-alcoholic extracts of leaves of Jasminium abyssinicum, Myrsine africana, Foenicum vulgare and aerial part of Leonotis ocymifolia were screened for antibacterial activity using agar well diffusion and broth dilution methods. Species of bacteria that cause various diseases in domestic animals namely, E…

Abstract: The genus Citrobacter is closely related to Salmonella and Escherichia coli, and there are some serological cross-reactions existing among these species. These cross-reactivities are caused by O-specific polysaccharide antigens in the LPS, which contain similar epitopes. In some cross-reactive strains, O-specific polysaccharides exhibit structural homology. In order to determinate the frequency of intra-strain variation of lipopolysaccharides (LPS) from Citrobacter freundii E9750 by in vitro passages at two differe…

Abstract: The sensitivity of five pathogenic multi drug resistant bacteria (Bacillus subtilis, Erwinia chrysanthemi, Escherichia coli, Agrobacterium tumefaciens and Xanthomonas phaseoli) was tested against the crude leaf organic extracts (methanol, ethanol, chloroform and hexane) and aqueous extracts of a Kumaun Himalayan gymnospermous plant Juniperus communis (Cupressaceae), employing disc diffusion method. All the extracts of Juniperus communis were found effective by showing a mark zone of inhibition except aqueous extrac…

Abstract: The main reasons of fungal expansion in museums are inadequate relative humidity and temperature and the spore’s germination can be controlled by regulation of these two factors. Numerous paintings, originated from 11 Serbian museums, were analyzed for presence of moulds. Samples from canvas, dyes and wooden frames with visual changes were subjected to the analysis. Species of genera Alternaria, Aspergillus, Aureobasidium, Cladosporium, Drechslera, Epicoccum, Penicillium, Rhizopus, Trichoderma, Ulocladium and Wardo…

Abstract: Microbiological and Physicochemical survey was undertaken in produced water and its receiving environment with the aim of verifying the likely impacts of produced water constituents on the immediate receiving marine near shore shallow environment. The sampling was carried out in two seasons, late wet season and late dry season. The results obtained indicate that the chemical constituents of the discharged produce water are capable of sustaining microbial growth and proliferation. Produce water from Escravos tank fa…

Abstract: Hepatitis B virus, a common cause of viral hepatitis, consumes a large portion of health resources in developing countries. Hepatitis B virus (HBV) prevalence has been decreased dramatically in Iran population during the last decade, and now it is classified as having low endemicity for hepatitis B infection. Improvement of the people’s awareness about HBV risk factors, national vaccination program since 1993 for all neonates, and vaccination of high risk groups could be the cause of this decrease. In this investig…

Abstract: Sixty-one isolates including molds, yeasts and bacteria from the forest soils collected from Hunan Province, China were tested for their potentiality to accumulate microbial lipid as alternative sources for biodiesel production. The results showed that sixteen mold isolates were potential oleaginous microorganisms, among which, strain SCIM 3.009 was the best lipid producers, which may accumulate up to 50.4% of lipids in dry biomass. Further study showed that the components profile of the lipid from strain SCIM 3.00…

Abstract: Effluent samples from two top Nigerian food and beverage industries, swords food industry and 7-Up Bottling Company, Ibadan, Oyo State, Nigeria were investigated for microbial loads, physiochemical properties and presence of heavy metals. While repeated sampling revealed two bacteria and a fungus from the effluents of 7-Up bottling company, 15 bacteria and 5 fungi were isolated from Swords foods Industry. The biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were equally higher in the effluent of swo…

Abstract: The incidence of adenovirus type 3 infections in camels in Sudan was studied. Lungs of Camel with pneumonia lungs (n = 239) were collected from slaughter houses at four different areas in Sudan. Adenovirus type 3 antigen was detected in 1.3% of 239 tested camel lungs by the use of sandwich ELISA. Specimens from Northern (3.3%) and Central Sudan (1.2%) were found to be positives. Direct fluorescent antibody test (FAT) was used to confirm the adenovirus ELISA positives; all ELISA positives were found to be positive u…

Abstract: Pathogenic clostridia produce exocellular toxins that resemble lipoteichoic acid and are described as super antigens. These toxins stimulate T-cell receptor-carrying lymphocytes in peripheral blood and have been used to study immunodeficiency diseases and cancers. The CPE C -terminal region from one of the local type A strain was cloned in the pET32a vector its expression induced with IPTG. The expressed protein was purified by Ni-NTA affinity chromatography and tested for biological activity with Vero cells assay…

Abstract: As one of the most successful groups of microalgae in the contemporary ocean, diatoms are of ecological, biotechnological and evolutionary significance. Recent research has revealed for the first time the presence of functional silencing machinery in diatoms. Nevertheless, no microRNAs (miRNAs) participating in their gene regulation have been reported. Based on the principle of sequence conservation, previous known plant miRNAs were blasted against the expressed sequence tag databases of the marine diatoms Phaeodac…

Abstract: Extended-spectrum beta-lactamases (ESBLs) are most prevalent in Klebsiella pneumoniae. This organism is frequently isolated from clinical specimens and can cause septicemia, pneumonia or urinary tract infection. We investigated a spread of Klebsiella spp. isolates producing ESBL in a university hospital of Sanandaj- Iran. Over one year period, a total of 48 K. pneumoniae isolates, were examined by double disk tests and PCR methods. Ten isolates were defined as ESBLs. The ESBL producer isolates was more resistant to…

Abstract: In this study, the enhancement of citric acid production from local molasses was attempted by mutagenesis. A local stain of Aspergillus niger was isolated from lemon leaves and treated with nitrous acid. The obtained mutant and the wild type of A. niger were separately used for the bioconversion of the local molasses into citric acid. The molasses fermentation was carried out at 30°C in a stirred flask. The results showed that the mutant exhibited an increased efficiency for citric acid production when compared wit…
