[Quinolone resistant Campylobacter jejuni strains isolated from humans and from poultry].

Eight quinolone resistant Campylobacter jejuni strains isolated from humans with diarrheal disease were compared with 23 isolates from chicken and from laying hens. Samples were cultured on selective agar in microaerophilia, identified by conventional tests, and conserved in 17% glycerol at -70 C. Clones were determined by RAPD-PCR employing the 1254 primer (Stern NJ).

[Prevalence of the bacteria causing diarrea in a Rosario Hospital, Argentina].

Bacterial agents causing diarrea in patients attended in a hospital of Rosario, Argentina. The frequency of bacterial agents causing diarrhea can vary in patients of different areas, and through the time. In an epidemiological surveillance we studied 304 patients with diarrheal diseases looking for Salmonella enterica, Shigella spp, Campylobacter spp, Aeromonas spp, Yersinia enterocolitica, and diarrheogenic Escherichia coli.

[Two cases of enteritis with bacteremia due to Campylobacter jejuni].

Campylobacter is an important agent of illness in human beings. Bacteremia occurs principally in the immunocompromissed host and is frequently due to C. fetus.

[Risk factors associated with ceftazidime-resistant Klebsiella pneumoniae infection].

Introduction: Risk factors associated with ceftazidime-resistant Klebsiella pneumoniae (CAZ-R Kp) infection may vary among hospitals and in the same hospital at different time points. Knowledge of these factors is required to establish suitable infection control programs.

Methods: A case-control study was conducted to assess risk factors for CAZ-R Kp infection.
