Fifty E. coli strains isolated from chicken flocks were analyzed to determine their resistance to antimicrobial agents used in Tehran poultry industry. By using Mast Diagnostic kit only O6 serotype was identified. Multiple resistance to antibiotics was observed in all isolates. The highest rate of resistance was against Tetracycline (94%), followed by Rifampicin (90%), and Oxytetracycline (80%)...
Background and Objective: The global increase in resistance to antibiotics among clinical isolates of Acinetobacter baumannii is reported from several countries, but its true prevalence in Iran is less known. The objective of this study was determination of the frequency of resistance to different antibiotics among Acinetobacter baumannii isolated from patients in two hospitals in Tehran, Iran,...
background: reduced susceptibility of clostridium difficile to antibiotics is problematic in clinical settings. there is new evidence indicating the cotransfer of toxin-encoding genes and conjugative transposons encoding resistance to antibiotics among different c. difficile strains. to analyze this association, in the current study, we evaluated the frequency of toxigenic c. difficile among th...
Background and Objectives: widely use of antibiotics as therapy and uncontrolled discharge of them to receiving waters increased the percentages of antibiotic resistant bacteria in various environments which may cause problems in therapy. The aim of this study was to investigate the antibiotic resistance of E. coli, K. pneumoniae and P. aeruginosa bacteria isolated from urban and hospital waste...
Abstract Bachground and Objective: most of environmental microorganisms have the genes resistance to antibiotics and metals. The aim of the current study was to survey resistance pattern to some antibiotics and heavy metals in three pseudomonas aeruginosa isolated from different ecological areas. Material and Methods: first, the isolates were identified by biochemical methods and phylogenetic a...
Background: The isolation of the TEM gene in Pseudomonas aeruginosa and Escherichia coli and the antibiotic resistance pattern provides useful information on the epidemiology and factors involved in these infections. Aim: The aim of this study was to evaluate antibiotic resistance and abundance of a beta-lactamase gene (TEM) in P.aeruginosa and E.coli isolated from clinical specimens by the po...
Background: Staphylococcus aureus is a facultative anaerobic Gram-positive coccal bacterium which is frequently found as part of the normal flora on the skin and nasal passages. S. aureus can cause a range of illnesses from minor skin infections to life-threatening diseases. The organism is able to developresistance to a wide range of antibiotics. Resistance to antibiotic is one of th...
the aim of this study was to determine the occurrence and the level of antibiotic resistance patterns in 62 salmonella isolates obtained from broiler chicken farms in amol, iran to common antibiotics in iranian poultry industry. antimicroibia resistance testing was performed using 7 useful antibiotics tetracycline, flumequin, lincospectin, florfenicol, neomycin, danofloxacin and enrofluxacin fo...
Klebsiella pneumonia is a gram negative bacillus of which it's resistant strains are a common source of nosocomial infections . The goal of this study is determination of drug sensitivity of these resistant strains, and study of causes involved in the resistant especially the presence of plasmid. Ten different strains of klebsiella pneumoniae were isolated from clinical specimens collected from...
