Sažetak
Four porcine strains of Escherichia coli were examined for their effects on the small intestine of 4-week-old weaned pigs infected orogastrically. The strains used experimentally were: strain 1467 (adhesin negative ; non-toxigenic) ; strains 2407 and 1466 (adhesin positive, non-toxigenic), derived by genetical engineering from strain 1467 and containing a wild type plasmid and a recombinant plasmid, respectively, encoding the F4 antigen (adhesin) ; and strain M1823 (adhesin positive, toxigenic). In addition, 2-week-old pigs that died from natural colibacillosis associated with two strains ("Ihan 1 and 2" ; adhesin positive, toxigenic) were examined.
