Escherichia coli O157 : H7 is increasingly recognized as a cause of bacterial diarrhea in the United States, but the frequency of its isolation and the clinical and epidemiologic features of E. coli O157 : H7 infection in a large, geographically diverse population of patients have not been well described.
To determine the frequency of isolation of E. coli 0157 : H7 relative to that of other bacterial enteric pathogens in a nationwide sample of patients and to identify the clinical and epidemiologic features of E. coli 0157 : H7 infection.
Population prevalence study from October 1990 to October 1992.
10 U.S. hospitals.
Both inpatients and outpatients who had stool samples submitted to 1 of 10 laboratories for routine pathogen identification.
Clinical, epidemiologic, and laboratory information was collected for infected and uninfected patients.
Isolates of E. coli 0157 : H7 were tested for production of Shiga toxin.
Escherichia coli 0157 : H7 was isolated from 118 (0.39%) of the 30 463 fecal specimens tested.
The proportion of fecal specimens with isolates was higher at northern sites (0.57%) than at southern sites (0.13%) (P<0.001).
Escherichia coli 0157 : H7 was more likely to be isolated from visibly bloody stool specimens than from specimens without visible blood (odds ratio [OR], 59.2 [95% Cl, 36.6 to 96. (...)
