Abstract

Mycoplasma haemomuris is a causative organism of infectious anemia or splenomegaly in rodents. Here, we report two distinct genetic groups among M. haemomuris strains detected from rats and mice, respectively, by examining the nucleotide sequences of the 16S-23S rRNA intergenic transcribed spacer region that has been shown to be a stable genetic marker for mycoplasma species. Our results may reveal host-tropism of each cluster of M. haemomuris strains, and suggest an idea to distinguish M. haemomuris into two different genetic clusters.
