[Enterotoxigenic capacity of strains of Klebsiella and Enterobacter genera isolated in acute intestinal diseases in children].
234 strains, including 104 K. pneumoniae strains, 28 K. oxytoxica strains, 64 E. cloacae strains and 40 E. aerogenes strains, have been isolated from the intestine of 266 children with diarrhea, aged up to 1 year, and studied for enterotoxigenicity. By the coagglutination test, made with G. Kronvall's staphylococcal reagent prepared with the use of antiserum to Escherichia coli LT-enterotoxin, and the biological assay on suckling mice enterotoxigenic activity has been revealed in 119 strains, including 48 K. pneumoniae strains (12.6%), 33 E. cloacae strains (27.4%) and 23 E. aerogenes strains (19.7%). The strains producing only LT-enterotoxins, only ST-enterotoxins, and both LT- and ST-enterotoxins have been found. The determination of the enterotoxigenic activity of the clinical isolates of opportunistic enterobacteria makes it possible to improve the etiological interpretation of acute intestinal infections.
