Abstract
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. Die 3-Jahres-Prävalenz enteropathogener Bakterien betrug 3,1% bei Patienten in einer deutschen Großstadt. Enteritis-Salmonellen zeigten eine Prävalenz von 1,8% und stellten einen Anteil von 59,3% aller isolierten enteropathogenen Bakterien, gefolgt vonCampylobacter spp. mit einem Anteil von 22,1%.Clostridium difficile-Toxin wurde in 5,6% mit entsprechender Fragestellung eingesandter Proben gefunden. Die saisonale Verteilung der Isolate zeigte einen Anstieg vonSalmonella-, Shigella- undAeromonas/Plesiomonas-Stämmen in der (Nach)-Urlaubszeit, was zum Teil durch zurückkehrende Urlauber bedingt ist. Ein 5-facher, epidemischer Anstieg vonSalmonella enteritidis-Isolaten wurde im Untersuchungszeitraum beobachtet. Enteropathogene Bakterien wieSalmonellen, Campylobacter undC. difficile wurden als häufige Ursachen von enteralen Infektionen bei HIV-infizierten Patienten nachgewiesen. Besonders Reisende und HIV-infizierte Patienten haben ein erhöhtes Risiko zur Entwicklung von Infektionen des Gastrointestinaltraktes. Präventive Maßnahmen zur Kontrolle derSalmonella enteritidis-Epidemie sind dringend notwendig.Keywords
