[Enterotoxigenicity of opportunistic enterobacteria in acute intestinal diseases in children].

The enterotoxigenicity of 244 cultures of opportunistic enterobacteria isolated from 129 infants (up to 1 year old) with acute intestinal diseases and of 120 cultures of opportunistic enterobacteria isolated from 60 practically healthy children of the same age, having no record of intestinal disorders in their medical history, was studied. The study revealed that enterotoxigenic opportunistic enterobacteria were isolated from 68.99% of sick children, while from healthy children enterotoxigenic cultures were isolated in 3.33% of cases. Besides E. coli, enterotoxigenicity was also detected in other representatives of the family Enterobacteriaceae: C. freundii, Arizona, K. pneumoniae, H. alvei, Pr. vulgaris, Pr. morganii, Pr. rettgeri, Y. enterocolitica.
