Complete genome sequence of the animal pathogen Listeria ivanovii, which provides insights into host specificities and evolution of the genus Listeria.

We report the complete and annotated genome sequence of the animal pathogen Listeria ivanovii subsp. ivanovii strain PAM 55 (serotype 5), isolated in 1997 in Spain from an outbreak of abortion in sheep. The sequence and its analysis are available at an interactive genome browser at the Institut Pasteur (http://genolist.

Complete genome sequence of Listeria seeligeri, a nonpathogenic member of the genus Listeria.

We report the complete and annotated genome sequence of the nonpathogenic Listeria seeligeri SLCC3954 serovar 1/2b type strain harboring the smallest completely sequenced genome of the genus Listeria.

Whole-genome sequence of Listeria welshimeri reveals common steps in genome reduction with Listeria innocua as compared to Listeria monocytogenes.

We present the complete genome sequence of Listeria welshimeri, a nonpathogenic member of the genus Listeria. Listeria welshimeri harbors a circular chromosome of 2,814,130 bp with 2,780 open reading frames. Comparative genomic analysis of chromosomal regions between L.

Evolutionary history of the genus Listeria and its virulence genes.

The genus Listeria contains the two pathogenic species Listeria monocytogenes and Listeria ivanovii and the four apparently apathogenic species Listeria innocua, Listeria seeligeri, Listeria welshimeri, and Listeria grayi. Pathogenicity of the former two species is enabled by an approximately 9 kb virulence gene cluster which is also present in a modified form in L. seeligeri.

Recurrent Listeria monocytogenes aortic graft infection: confirmation of relapse by molecular subtyping.

Based on molecular typing methods, we identified a rare case of a recurrent L. monocytogenes infection resulting from an infected aortic prosthesis as detected by 18-F-Fluoro-d-deoxyglucose positron emission tomography (FDG PET). Our case highlights the usefulness of molecular typing and nuclear imaging methods for understanding L.
