Pathogenic effect of entero toxigenic escherichia coli and escherichia coli causing infantile diarrhea



Pathogenic effect of entero toxigenic escherichia coli and escherichia coli causing infantile diarrhea



Acta Microbiologica Academiae Scientiarum Hungaricae 24(3): 221-236



Macroscopic, light microscopic and EM alterations in ligated rabbit intestinal loops challenged with 5 standard enterotoxigenic E. coli (ETEC) and 23 enteropathogenic E. coli (EEC-I) strains, freshly isolated from infantile enteritis cases, were investigated. Only 2 O26: K60: H11 strains produced enterotoxin. Viable cultures, sterile filtrates of the fluid medium and ultrasonic lysates of the bacteria resulted in pronounced hypersecretion of the intestinal epithelium followed by fluid accumulation and loop dilatation. These 2 E. coli strains, similar to other loop-negative EEC-I strains, penetrated into the intestinal epithelium. Unlike the standard ETEC strains, the EEC-I bacteria, adhering to the brush border, intruded into the microvilli, multiplied on the outer epithelial cell membrane making close contact with it and, causing shedding of microvilli, penetrated into enterocytes becoming enclosed in membrane-bound phagosome-like vacuoles, appeared in the lamina propria and elicited mild focal polymorphonuclear infiltration.
