Abstract
The relative contributions of toxin-coregulated pilus (TCP) and cell-a ssociated mannose-sensitive hemagglutinin (MSHA) to the colonization a bility of Vibrio cholerae O1 El Tor biotype strains and O139 Bengal st rains was determined by using isogenic parental and in-frame deletion mutant pairs in the infant mouse cholera model. Both the El Tor and O1 39 tcpA mutant strains showed a dramatic defect in colonization as ind icated by their competitive indices, whereas deletion of mshA had a ne gligible effect on colonization in either background.
