Molecular demonstration of hemotropic mycoplasmas in wild Japanese monkeys (Macaca fuscata).

The prevalence of hemotropic mycoplasmas in wild monkeys is largely unknown. Here, we report the presence of hemoplasmas in blood specimens collected from wild Japanese monkeys (Macaca fuscata) tentatively captured for ecological survey in Mie prefecture, Japan. We examined 9 monkeys using hemoplasma-specific real-time PCR and found all of them positive for a hemoplasma infection.

Detection of hemotropic mycoplasmas in free-living brown sewer rats (Rattus norvegicus).

The prevalence of hemotropic mycoplasmas in wild rodents is largely unknown. Here, we report the presence of hemoplasmas in blood samples collected from brown sewer rats (Rattus norvegicus) trapped during rodent control around an animal hospital in Morioka, Japan. We examined nine rats using real-time PCR and end-point PCR, and found one rat (11.

Hemotropic mycoplasma infection in wild black bears (Ursus thibetanus japonicus).

This is the first report on Mycoplasma infection in wild bears. We report a novel hemotropic Mycoplasma (also called hemoplasma) detected in a free-ranging black bear (Ursus thibetanus japonicus) in Japan. We then used real-time PCR to look for hemoplasma DNA in blood samples collected from 15 bears and found that eight (53%) were positive.

Two clusters among Mycoplasma haemomuris strains, defined by the 16S-23S rRNA intergenic transcribed spacer sequences.

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.
