results in general 438 urine isolates were obtained. e. coli was the most frequently occurring pathogen (54.80%), followed by klebsiella pneumoniae (16.0%), coagulase negative staphylococci (11.2%), enterobacter spp. (9.6%), proteus spp. 1.4% and p. aeruginosa (1.4%). resistance rates of e. coli isolates were 85.9% to co-trimoxazole, 80.0% to penicillin, 77.0% to ampicillin, 68.0% to chloramphe...

conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...

The accuracy of antimicrobial susceptibility tests is a crucial step for the clinical management of patients with serious infections. They must be reliable and precise because they will guide antimicrobial therapy. Our main objective was to compare the results of susceptibility testing performed by the SENTRY coordinator laboratory with those reported by the participating Latin American medical...

  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 ne...

Using 21 antimicrobial agents, agar dilution susceptibility tests were carried out against 190 strains of Yersinia enterocolitica. Isolates from human, environmental, and animal sources had essentially equal susceptibility patterns.

The number of U.S. hospital discharges in which there was a diagnosis of infection with drugresistant microorganisms increased more than one hundred-fold between 1993 and 2005. Among the concerns over drug-resistant microorganisms is the rapid increase in the incidence of such infections acquired by patients within the hospital or healthcare setting. Infectious disease experts have argued that ...

ornithobacterium rhinotracheale (ort) is a bacterium associated with respiratory disease, growth retardation, decreased egg production and mortality in chickens and turkeys. the objective of this study was isolation, identification and evaluation of antimicrobial susceptibility of ort bacterium in slaughtered broilers chicken flocks based on cultural and molecular tests in khuzestan province, s...
