摘要

An enzyme-linked immunosorbent assay (ELISA) produced by LMD Laboratories, Inc., Carlsbad, Calif., was compared with culture for the detection of Escherichia coli O157. Nine of 185 stool specimens evaluated had positive results by the LMD E. coli O157 ELISA and grew E. coli O157 on culture; 174 had negative by LMD E. coli O157 ELISA results and did not grow E. coli O157 on culture. Of 174 specimens negative by LMD E. coli O157 ELISA, 117 specimens grew other enteric pathogens: Campylobacter spp. (46 isolates), Salmonella spp. (43 isolates), Yersinia spp. (20 isolates), and Shigella spp. (8 isolates). There were two indeterminant results by the LMD E. coli O157 ELISA. One stool specimen did not grow other enteric pathogens on culture, and one grew a Campylobacter sp. on culture. Both had negative LMD E. coli O157 ELISA results upon repeat testing. The LMD E. coli O157 ELISA is an accurate, easy-to-read screening method for the detection of E. coli O157 in fecal specimens.
