Background: The resistance of Pseudomonas aeruginosa strains to broad spectrum cephalosporins may be mediated by extended spectrum b-lactamases (ESBLs). These enzymes are encoded by different genes located either on chromosome or plasmids. In this study, we determined the antimicrobial resistance patterns of P. aeruginosa isolates and screened for ESBL production. Methods: After isolation from...

Background: The antibiotic resistance is considered as one of the biggest public health concerns in most countries. The aim of this study was to determine antibiotic resistance pattern of Escherichia coli isolated from chickens with colibacillosis in Yazd, Iran. Methods: A total of 200 carcasses of Ross chickens with colibacillosis were collected from farms located around Yazd, central Iran. A...

Background & Aims of the Study: Methicillin-resistant staphylococcus aureus (MRSA) is considered as a major pathogen in public health concern. The objectives of this study were to firstly determine antibiotic sensitivity among Staphylococcus aureus isolated from traditional Iranian white cheese during 2015 from Hamedan province of Iran; and secondly to estimate the presence of ...

Antimicrobial properties of phytochemicals extracted from onion (Allium cepa) and ginger (Zingiber officinale) were evaluated against Escherichia coli and Staphylococcus aureus, two common food borne pathogens. They were tested using minimum inhibitory concentration, minimum bactericidal concentration disc diffusion and agar wells diffusion. Onion showed good antimicrobial properties against S....

AIM This study was designed to describe a series of in vitro tests that may aid the discovery of probiotic strains from actinomycetes. MATERIALS AND METHODS Actinomycetes were isolated from marine sediments using four different isolation media, followed by antimicrobial activity and toxicity assessment by the agar diffusion method and the hemolysis of human blood cells, respectively. Extracel...

Objective: To investigate in vitro bioactivities of methanol, ethyl acetate, chloroform, hexane, ethanol and aqueous extracts of E. nummularius and its phytochemical analysis. Methods: The antioxidant activity was determined by measuring the scavenging activity of DPPH radicals and H2O2. Cytotoxic activity was tested against hep G2 cell lines using MTT assay. Antimicrobial activity was assessed...
