title: [Direct detection in diarrheal stools of Escherichia coli adhesion factors CFA/I, CFA/II and E8775 by the india ink immune reaction].
abstract: An India ink immune reaction was used for the direct detection, in diarrhoeal stools, of Escherichia coli possessing the CFA/I, CFA/II and E8775 fimbriae. With this method, a presumptive diagnosis of enterotoxigenic E. coli (ETEC) can rapidly be made. Staining required the bivalency of rabbit anti-fimbriae IgG; the F(ab')2 fragment was necessary. The reaction was impossible with purified Fab fragment. A comparative study of this technique and detection by culture of ETEC strains showed good correlation when the India ink immune reaction was performed at the beginning of infection.
