background and objectives: staphylococcus aureus ( s. aureus ) nasal carriage may be responsible for some serious infections in hemodialyzed patients. the main target of this study was to estimate the prevalence of s. aureus nasal carriage in hemodialysis outpatients and medical staff in hemodialysis centers specifically in fez region. the second target is to identify the risks of colonization,...

  Background and Objectives: Blood stream infections cause significant morbidity and mortality in the world. In this study, we aimed at describing the organisms responsible for septicemia in 2006-2007 and their antimicrobial susceptibility that might lead to proper selection of antimicrobial agents in hospitalized patients with suspected sepsis. Materials and Methods: Microbiology reports of ...

A test of 25 genetically diverse isolates of Bacillus anthracis was conducted to determine their susceptibility to seven clinically relevant antimicrobial agents. Etest strips (AB BIODISK, Solna, Sweden) were used to measure the MICs for the isolates. Using the National Committee for Clinical Laboratory Standards MIC breakpoints for staphylococci, three isolates were found to be resistant to pe...

A total of 78 isolates of Pseudomonas aeruginosa grouped according to the phenotype for ceftazidime and imipenem susceptibility/resistance were used to assess the accuracy of the Vitek 2 system in antimicrobial susceptibility testing. Comparisons were made with a MIC gradient test for piperacillin-tazobactam, ceftazidime, aztreonam, imipenem, meropenem, gentamicin, and ciprofloxacin. For the to...

Studies were conducted to compare and evaluate antimicrobial susceptibility test results for enterococci obtained by six national committee disk diffusion procedures. Variations in the incidence of isolates in resistance categories and errors were associated with the use of ciprofloxacin, gentamicin, nitrofurantoin, rifampin, and teicoplanin in a number of committee procedures. Results indicate...

background and objectives: the appearance of antibiotic resistance in streptococcus pneumoniae has raised a global concern over the past three decades. this study was conducted to determine the antimicrobial susceptibility of s. pneumoniae isolated from patients in children´s medical center (cmc) hospital during 2001 to 2011. materials and methods: during the 11 years period, a total of 194 s. ...

Brucellosis is a world-wide zoonotic disease with a major impact on the public health. Due to the high risk of laboratory acquired infection, limited laboratory investigations were performed on this organism, including detailed identification and susceptibility study. Brucella melitensis is the commonest aetiological agent for human brucellosis in this region. The in vitro susceptibility patter...

The present study was done to detect the antibiotic resistance in S. pneumoniae. One hundred twenty S. pneumoniae isolates from clinical specimens and 50 from nasopharyngeal sites were subjected to antimicrobial susceptibility testing by Kirby Bauer disk diffusion method and minimum inhibitory concentration (MIC) determination for penicillin and cefotaxime non-susceptible isolates. A total of 2...

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...
