Identification of a mutation in the pst-phoU operon that reduces pathogenicity of an Escherichia coli strain causing septicemia in pigs.

Infection and immunity - 1 Dec 1995

Daigle F, Fairbrother J M, Harel J

Abstract excerpt

We used transposon (TnphoA) mutagenesis to study the role of virulence factors of pathogenic Escherichia coli strains associated with septicemia in calves and piglets. We have produced an avirulent and serum-sensitive mutant of wild-type pathogenic strain 5131 O115:K"V165":F165 and have localized and identified the TnphoA insertion in the pstC gene of the pst-phoU operon. This operon encodes the PstSCAB...
