title: [Detection of heat-labile enterotoxin produced by E. coli with reversed passive latex agglutination].
abstract: From June 1987 to March 1988, 103 E. coli strains were collected from non-foodborne samples, foodborne samples, FDA (USA) etc. and analyzed for heat-labile E. coli enterotoxin (LT) by reversed passive latex agglutination (RPLA). The results showed that 84 strains were LT-positive, 19 strains were LT-negative. Forty six strains of enteropathogenic E. coli isolated from foodborne samples showed that 34 strains were LT-positive, 12 strains were negative. Four enterotoxigenic E. coli strains from FDA (USA) used as positive controls, can produce heat-labile E. coli enterotoxin and give positive results.
