Type 1 pili (F1) of porcine enterotoxigenic Escherichia coli: vaccine trial and tests for production in the small intestine during disease.


This study was performed to determine whether the F1 (type 1) pili of a porcine strain of enterotoxigenic Escherichia coli are protective antigens and whether they are produced in the pig small intestine during disease caused by an enterotoxigenic E. coli. Reciprocal cross-absorption experiments with antisera prepared against F1 pili purified from… (More)
