Serological Cross-Reactions between 'Escherichia coli' O157 and other Species of the Genus 'Escherichia'.

摘要

The antigenic relatedness of Escherichia coli O157 and four sorbitol-negative species of the genus Escherichia was examined. Isolates of Escherichia hermannii, E. fergusonii, E. vulneris, and E. blattae were tested in the tube agglutination assay by using polyclonal antisera and in the slide agglutination assay by using latex reagents. Only four isolates (17%) of E. hermannii exhibited serological cross-reactivity. (Copyright (c) 1992, American Society for Microbiology.)
