The type strain ATCC 15313 of Listeria monocytogenes is not typical of the species. This strain has an atypical antigenic structure, is nonhemolytic on sheep blood agar (but is hemolytic on rabbit blood agar), lacks motility, is nonpathogenic in mice, and shows limited cytopathogenic effects on Caco-2 monolayers [1, 2]. Moreover, there are important differences betwen the strain ATCC 15313 and the strain SLCC 53 (the strain SLCC 53 is unable to produce lecithinase, is nonhemolytic on rabbit or sheep blood agar, is motile, and shows no cytopathogenic effects on Caco-2 monolayers) . In 1983, J. Dorothy and H.P.R. Seeliger  requested that strain ATCC 15313 be replaced by strain NCTC 7973 as the type strain. This request was prepared on behalf of and with the unanimous endorsement of the ICSB Subcommittee on the Taxonomy of Listeria. However, this proposal was disapproved by the Judicial Commission [3, 4], and the type strain is still strain ATCC 15313.Publication:
