Abstract

Enterotoxigenic Escherichia coli was isolated from a 3-day-old foal with diarrhea. The isolate was distinguished from nonpathogenic E coli by determining the presence of pili and enterotoxin production. A standard slide agglutination test was performed, using pooled antisera that contained antibodies against K99 and F41 pilus antigens, K87 capsular antigen, and 0101 somatic antigen. Agglutination of the antisera occurred in the presence of the isolate. Piliation was verified by use of negative-contrast electron microscopy. Further, the isolate produced a heat-labile enterotoxin-like antigen that cross-reacted with a reagent containing formalin-treated, heat-killed Staphylococcus aureus (cowan 1 strain) bearing anti-cholera antibodies. On the basis of the aforementioned procedures and the absence of other identifiable enteric pathogens, we believe that E coli was responsible for causing diarrhea in the foal.
