[D-mannose-resistant hemagglutination in opportunistic enterobacteria in infantile diarrhea].

D-mannose-resistant hemagglutination with human and bovine red blood cells was determined in 284 cultures of opportunistis enterobacteria isolated from 99 patients with acute intestinal infections and in 55 cultures isolated from 27 practically healthy children aged up to 1 year. In 16 sick children (16.16%) opportunistic enterobacteria, positive when tested in D-mannose-resistant hemagglutination, were detected.
