Some Azomethines of 5-amino isophthalic acid were synthesized and their antibacterial activity was studied in DMSO against four Gram positive Bacillus cereus ATCC11778, Staphylococcus aureus ATCC29737, Staphylococcus epidermidids NCIM2493 and Micrococcus luteus ATCC10240, and three Gram negative bacteria viz. Proteus mirabilis NCIM2241, Escherichia coli ATCC25922 and Klebsiella aerogenes NICM20...

        Freshwater crayfish (Astacus leptodactylus) is an important economic fisheries resource of Aras reservoir, Iran. The infection of freshwater crayfish by gram negative and gram positive bacteria are common in natural and cultural environments. These bacteria are considered as secondary disease agents or opportunities. This study was conducted to investigate infes...

background: treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. the aim of this study was to determine the multidrug resistance (mdr) pattern of the bacteria causing chronic sinusitis in north of iran. methods: this cross-sectional study was carried out on patients with chronic sinusitis. bacterial susceptibility to antimicrobial agents was determined...

BACKGROUND For precise diagnosis of urinary tract infections (UTI), and selection of the appropriate prescriptions for their treatment, we explored a simple and rapid method of discriminating gram-positive and gram-negative bacteria in liquid samples. METHODOLOGY/PRINCIPAL FINDINGS We employed the NaOH-sodium dodecyl sulfate (SDS) solution conventionally used for plasmid extraction from Esche...
