Three-year prevalence of enteropathogenic bacteria in an urban patient population in Germany
1993
The prevalence of enteropathogenic bacteria over a three-year period was 3.1% in an urban population in Germany. NontyphoidalSalmonella spp. (1.8% prevalence) represented 59.3% of all positive isolates, followed byCampylobacter spp., which constituted 22.1% of such isolates.Clostridium difficile toxin was detected in 5.6% of samples submitted specifically for detection of cytotoxigenicC. difficile. The seasonal distribution showed an increase ofSalmonella, Shigella andAeromonas/Plesiomonas isolates in the post-holiday season, partly due to returning travelers. An epidemic five-fold increase ofSalmonella enteritidis isolates was found over the three-year-period. Enteropathogenic bacteria such asSalmonella, Campylobacter and cytotoxigenicC. difficile were common etiologic agents of gastrointestinal tract infections in patients with AIDS. We conclude that travelers and HIV-infected subjects are especially prone to infection with enteropathogenic bacteria; preventive measures to control theSalmonella enteritidis epidemic are essential.
