Three enterotoxigenic Escherichia coli (ETEC) strains (coded 62, 104, and 567/7) isolated from piglets with neonatal diarrhea produced only a thermostable enterotoxin. Although these strains showed mannose-resistant microhemagglutination (MRMH), the responsible factor was serologically different from the known hemagglutinating colonization factors from porcine strains (K88, K99, and F41). Bacterial cells from these strains adhered to HeLa cells and pig brush borders. Electron microscope studies revealed the presence of fimbria-like structures on bacterial cells grown at 37C but not on cells grown at 18C. The antiserum prepared from partially purified fimbrial antigen (provisionally called F42) inhibited chicken erythrocyte MRMH caused by these strains as well as adherence of strain 567/7 to HeLa cells and to pig brush borders. These data taken together suggest the existence of a new hemagglutinating adhesin that is different from those so far described for porcine ETEC.
