Verotoxigenic Escherichia coli Infection: U.S. Overview
TL;DR: Analysis of DNA encoding virulence factors and surface antigens suggests that diarrheagenic E. coli have evolved by acquiring large DNA fragments, with subsequent chromosomal recombination, which suggests the incidence of endemic disease caused by this organism is probably not increasing, and might be decreasing, at least in selected populations.

TL;DR: Investigation of a 1995 outbreak of Escherichia coli O157:H7 infections and the safety of meat dehydration methods finds deer can be colonized by E coli O 157: H7 and can be a source of human infections.

TL;DR: Despite public warnings, new labeling requirements, and increased monitoring of dairy A, retail sales and dairy-associated infections continued until June 1994 (a total of 14 primary cases), and seven distinguishable PFGE patterns in 3 homology groups were identified among patient and dairy herd E. coli O157:H7 isolates.
