Wild type InlA does not interact with murine E-cadherin [38], but infection of wild type mice with L. monocytogenes expressing murinized InlA does not influence the course of feto-placental listeriosis [39], and in transgenic mice expressing human E-cadherin, InlA and/or InlB have a <5-fold effect on placental and fetal infection [37]. This evidence concerns the gene CDH1 and listeriosis.
