Abstract: Using transposon tnphoA, classical bacterial genetic assays, SDS-PAGE and Western blot of superficial proteins, we have studied the expression of the 31A fimbriae of two bovine wild-type septicaemic Escherichia coli strains. The genes responsible for encoding colonization factor 31A were located in both the plasmid (strain BZ2468) and the chromosome (strain BZ43). The results obtained using HeLa cell cultures led us to believe that the BZ43 strain could have another colonization factor besides 31 A, since one mutant, which did not express fimbriae, was still able to adhere to HeLa cells.
