title: Vero cytotoxin-producing Escherichia coli O157 infections in Austria.
abstract: To determine the prevalence of Vero cytotoxin-producing Escherichia coli (VTEC) serotype O157 associated diarrhea in the Austrian patient population, we surveyed all stool specimens of liquid consistency submitted to the Federal Public Health Laboratory (FPHL) in Innsbruck for 2 years for this organism. This laboratory serves a population of approximately 1 Million people. Of 5,265 stool specimens, 7 yielded O157 VTEC. Five isolates of E. coli O157 phage type 32, VT2 were cultured from specimens received during a three day period from residents in the county of Schwaz. During the investigation of this "outbreak" E. coli O157 strains were also isolated from two household contacts. Only 1 out of 8 persons with E. coli O157 diarrhea had bloody stools, although 5 of 7 tested specimens (= 71%) also yielded Campylobacter jejuni. None of our patients received antimicrobial therapy directed against E. coli O157 (one child had josamycin). There were no fatalities and no cases of hemolytic uremic syndrome (follow up period: 6 months). Consumption of hamburger, roast beef, and unpasteurized milk was not confirmed in this study. In Austria, no O157 VTEC strain was isolated till June 1992, although at the FPHL in Innsbruck stool specimens of liquid consistency were cultured for this organism since January 1991.
