Truncated internalin A and asymptomatic Listeria monocytogenes carriage: in vivo investigation by allelic exchange

Infect Immun. 2005 Jan;73(1):644-8. doi: 10.1128/IAI.73.1.644-648.2005.

Abstract

Allelic exchange of the region coding for the C terminus of InlA between one epidemic (with an 80-kDa InlA) and one asymptomatic (with a 47-kDa InlA) carriage Listeria monocytogenes strain confirmed the need for this region for internalin entry in vitro. Interestingly, restoration of internalin A functionality did not result in full virulence in chicken embryo assays.
