The Epsilometer test (E test; AB Biodisk, Solna, Sweden), a new quantitative technique for the determination of antimicrobial susceptibility, was compared to reference methods (agar dilution and broth microdilution) for the antimicrobial susceptibility testing of Helicobacter pylori. Seventy-one H. pylori strains isolated from patients with duodenal ulcers were tested against 20 antimicrobial a...

The selection of antimicrobial agents for the treatment of mastitis has often been based on results of in vitro susceptibility testing. However, the results of in vitro susceptibility tests have been shown to be poor predictors of treatment outcomes. The objective of this study was to determine if an association existed between results of antimicrobial susceptibility tests and outcomes of masti...

this study investigated the antibacterial resistance among enterococci isolated in tehran hospitals. a total of 277 enterococcus faecalis, 123 enterococcus faecium and 13 isolates of other enterococcal strains were collected from 1 march 2002 to 15 april 2004 from three teaching hospitals of tehran university of medical sciences. the minimum inhibitory concentrations (mic) of tested antibiotics...

coagulase-negative staphylococci (cns) are a main cause of nosocomial infection. the main purpose of this study was to determination of frequency of cns isolates in in hospitalized patients and their susceptibility pattern to antimicrobial agents. during 11 month study, 65 cns clinical isolates were recovered from hospitalized patients in different wards of hospital. in vitro susceptibility of ...

background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...

background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...

background ventilator- associated pneumonia (vap) continues to complicate the course of 8-28 % patients receiving mechanical ventilation. the mortality rate for vap is high, ranges from 24-50% and can reach 76% in some specific settings or when lung infection is caused by high risk pathogens. the etiologic agents widely differ according to the population of patients in an intensive care unit, d...

streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. the present investigation was carried out to determine some phenotypic characteristics of the s. agalactiae strains isolated from bovine mastitis cases in dairy cows of shahrekord in the west-center of iran. one hundred eighty california mastitis test (cmt) positive milk samples were bacteriologically ...
