The in vitro antibacterial activity of various antibiotics incfucling cefrxime against 73 clinical isolates o/Salmonella typhi from a vetriety of sources was evaluated by conventional agar-dih.uion metlod and Eîest. lB strains of these 73 strains were chloratnphenicol and cotrimoxazole (sulfcuttelhoxazole-trimetlnprtm) resistant arul I2 of these I8 strains were ttlso resistant to anroxicillin d...

Fusidic acid is a common therapy for staphylococcal infections in Saudi Arabia, but reports have suggested high rates of resistance among clinical isolates. Susceptibility testing of S. aureus to fusidic acid is further complicated by the lack of consensus on mean inhibitory concentrations (MIC) and disk diffusion cutoffs to determine resistance. The purpose of this study was to determine the c...

Due to the fastidious nature of B. henselae and the limited number of available isolates worldwide, there are few data on its in vitro susceptibility to antibiotics. We determined the minimal inhibitory concentrations (MIC) of ten antimicrobial agents against 11 feline isolates of B. henselae by Etest method. The lowest MICs were obtained for rifampicin < or = 0.002 mg/L. MICs of all isolates w...

BACKGROUND The emergence of carbapenem-resistant Acinetobacter baumannii (CRAB) was observed in a Kenyan hospital from 2009 to 2010. Further investigation of the dissemination of CRAB isolates and the molecular characterization of associated resistance determinants were therefore performed. METHODS Antibiotic susceptibilities were determined by broth microdilution and Etest. Metallo-β-lactama...

BACKGROUND Acinetobacter baumannii is an opportunistic microorganism with an increasing role in nosocomial outbreaks. For the last 2 decades, a growing number of carbapenem-resistant A. baumannii strains have been identified, including the metallo-beta-lactamases (MBLs) producers. The study aimed to investigate the genetic relatedness of, and MBLs production among, a collection of A. baumannii ...

OBJECTIVE The present study was undertaken to characterize CTX-M ESBL-producing Klebsiella pneumoniae collected from hospitals in different cities of Brazil. MATERIAL AND METHODS Eighty-five K. pneumoniae strains isolated from hospitalized patients in six different hospitals of three cities of Brazil were analyzed. ESBL production was confirmed by the standard double-disk synergy test and the...

The activities of nalidixic acid, ciprofloxacin, norfloxacin, ofloxacin, pefloxacin, flerofloxacin, sparfloxacin, grepafloxacin, gatifloxacin, moxifloxacin, trovafloxacin, levofloxacin and clinafloxacin against a panel of Haemophilus influenzae strains were assessed by three susceptibility testing methods: Etest, agar dilution and the reference broth microdilution method using Haemophilus test ...

OBJECTIVES A patient with Candida albicans thrush and oesophagitis was treated with high doses of caspofungin but treatment eventually failed. Four C. albicans isolates were serially recovered before and after caspofungin treatment. A microbiological study was performed to characterize these four isolates. METHODS In vitro antifungal susceptibility testing was performed by the EUCAST referenc...
