06/01/1979 - "Strains from piglets with diarrhea showed a high frequency of O-group 149 (53%), enterotoxicity (61%), and K88 antigen (56%), while not more than 3% of the strains from healthy piglets of the same age harbored any of these characteristics. "
06/01/1979 - "coli isolates from piglets with diarrhea and from representatives of healthy herds without diarrhea, with regard to (i) the homogeneity of strains in individual pigs and (ii) the distribution of O-groups, K88 antigen, and frequency of enterotoxicity. "
06/01/1979 - "In a comparison between piglets (1-7 days old) with diarrhea and healthy piglets of the same age and 1 to 8 weeks old, 810 intestinal strains of Escherichia coli from 81 piglets from as many different herds in Sweden were investigated with regard to O-group, enterotoxicity, and possession of K88 antigen. "
12/01/1972 - "The role of the K88 antigen of Escherichia coli in neonatal diarrhea of piglets was studied by comparing a K88-positive strain with three K88-negative strains derived from the K88-positive strain. "
12/01/1972 - "Role of the K88 antigen in the pathogenesis of neonatal diarrhea caused by Escherichia coli in piglets."
01/01/1981 - "Examples are the strong adhesion to epithelial cells by Escherichia coli strains bearing the K88 antigen (such strains need not be motile in order to be pathogenic) or the active chemotactic association with mucus gel by cholera vibrios (some of which do not appear to adhere strongly to epithelial cells).
