patients and methods: all samples sent to the lab were routinely processed according to standard microbiological procedures and the cultures yielding growth of cons were selected for the study. all samples containing cons collected over a 2 year-period, were included irrespective of patients' age and gender. the antibiogram of the organisms was recorded according to clsi guidelines and the rati...

thirty isolates of bacillus anthracis recovered from animal carcasses, soil and human in different localities in iran between 2007 and 2008. they were tested by standard disc diffusion susceptibility method for their resistant/ susceptibility to different kinds of antibiotics. according to american national committee of clinical laboratory standards (nccls) guidelines all isolates were sensi...

bacteremia is an important infectious disease which may lead to death. common bacteria and pattern of antibiotic resistance in different communities are different and understanding these differences is important. in the present study, relative frequency and pattern of drug resistance have been examined in bacteria isolated from blood cultures in razi hospital laboratory. the method of the study...

materials and methods lactic acid bacteria isolated from spoiled fruits and vegetables and grown in mrs medium were screened against multi-drug-resistant candida albicans, klebsiella pneumoniae, pseudomonas aeruginosa, escherichia coli, and enterococcus fecalis. results fifty-four lactic acid bacteria were isolated from spoiled fruits and vegetables, of which 11 gram-positive and catalase-negat...

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...

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...

Widespread use and misuse of penicillin and other antibiotics have resulted in development of resistance most antibiotics. The mechanisms by which microorganisms develop resistance to antibiotics are discussed. Topics covered include acquisition of point mutations and antibiotic resistance genes, methods of transfer of resistance genes between bacteria, and the advantages of synthetic antibioti...
