Abstract: Thirty one Escherichia coli strains isolated from pigs with urinary tract infections were investigated for presence of virulence factors and plasmid DNA profile. The most frequent virulence factors presented by these strains were mannose-resistant fimbriae, including P fimbriae (54.8%) and aerobactin production (45.2%). The pap operon, detected by PCR, was found in 54.8% of the strains, which is similar to its frequency in human strains. Other characteristics such as the presence of mannose-sensitive hemagglutinin (16.1%), indicative of type 1 pill, and production of hemolysin (25.8%), colicin (38.7%) and toxins (22.6% for LT and for VT) were less frequent, No strains were positive for STa production. Plasmid profiles were variable among isolates from either the same or different farms. (C) 1999 Elsevier Science B.V. All rights reserved.
