sp. nov. isolated from laboratory rodents.

Nine strains of a -related bacterium were isolated over a period of 38 years from a laboratory mouse (), seven laboratory rats () and a Syrian hamster () in Düsseldorf and Heidelberg, Germany. The isolates are genotypically and phenotypically distinct from all previously described species. Sequence analysis of 16S rRNA and gene sequences placed the isolates as a novel lineage within the genus .

Differentiation among the most important Rodentibacter species by multiplex PCR assays targeting the ITS sequences of the rRNA operons.

Screening for the Rodentibacter species is part of the microbiologic quality assurance programs of laboratory rodents all over the world. Nevertheless, currently there are no PCR amplification techniques available for the diagnostic of R. ratti, R.

Differentiation Among Species Based on 16S-23S rRNA Internal Transcribed Spacer Analysis.

The internal transcribed spacer (ITS) regions of , , , , and and of a related β-hemolytic taxon isolated from laboratory rodents were studied for their feasibility to discriminate among these species. The 6 species analyzed showed species-specific ITS patterns that were shared by the type strains and clinical isolates and that allowed their identification. Nevertheless, differentiating between the ITS band patterns of and is visually challenging.

Molecular Epidemiology of Methicillin-Susceptible and Methicillin-Resistant in Wild, Captive and Laboratory Rats: Effect of Habitat on the Nasal Population.

Rats are a reservoir of human- and livestock-associated methicillin-resistant (MRSA). However, the composition of the natural population in wild and laboratory rats is largely unknown. Here, 144 nasal isolates from free-living wild rats, captive wild rats and laboratory rats were genotyped and profiled for antibiotic resistances and human-specific virulence genes.

Development of multi locus sequence typing (MLST) of Rodentibacter pneumotropicus.

The aim of the investigation was to develop a definitive typing system for Rodentibacter pneumotropicus. A total of 79 strains including the type strain of R. pneumotropicus, all associated with rodents were used to develop a multi-locus sequence typing scheme (MLST).
