Abstract
Enterotoxigenic strains of Escherichia coli, which belonged to serogroups other than 06 and produced colonization factor antigen II, usually produced only coli surface antigen 3 (CS3) and gave weak mannose-resistant haemagglutination of bovine erythrocytes. A non-autotransferring plasmid, NTP165, from a strain of E. coli 0168. H16 coded for heat-stable enterotoxin, heat-labile enterotoxin and CS antigens. The CS antigens expressed after acquisition of plasmid NTP165 depended on the recipient strain: a biotype A strain of serotype 06. H16 expressed CS1 and CS3; a biotype C strain of serotype 06. H16 expressed CS2 and CS3; strain K12 and strain E19446 of serotype 0139.H28 expressed only CS3. An exceptional wild-type strain, E24377, of serotype 0139.H28 produced CS1 and CS3 when isolated; a variant of E24377 which had lost the plasmid coding for CS antigens produced both CS1 and CS3 after the introduction of NTP165.This publication has 12 references indexed in Scilit:
