Four hundred and fifty eight water samples collected from domestic tanks and taps and community taps were analysed for bacterial contamination. Faecal pollution was more in domestic tanks and taps in Mehmoodabad, Korangi and least in water collected from community taps of Liaquatabad, Korangi and Mehmoodabad. Bacteria isolated were mostly E. coli, Enterobacter sp, Klebsiella sp. and A. faecalis...

OBJECTIVES To investigate the association between the presence of a genetic island inserted within the sapABCDF operon of Salmonella Typhi and the susceptibility to antimicrobial peptides. METHODS Genetics and bioinformatics approaches were used to study the genomic organization of the sap operon of Salmonella Typhi and several serovars of Salmonella enterica. PCR was used to confirm the info...

Cladophora and Enteromorpha are the filamentous green-algal genuses that have a widespread distribution in Caspian Sea Coast. The aim of this study was to assess the antimicrobial activities of Cladophora and Enteromorpha in South of Caspian Sea. Antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including Staphylococcus aureus, Bacillus su...
