'Candidatus Mycoplasma haemomacaque' and Bartonella quintana Bacteremia in Cynomolgus Monkeys

Here, we report latent infections with Bartonella quintana and a hemotropic Mycoplasma sp. in a research colony of cynomolgus monkeys ( Macaca fascicularis ). Sequence alignments, evolutionary analysis, and signature nucleotide sequence motifs of the hemotropic Mycoplasma 16S rRNA and RNase P genes indicate the presence of a novel organism.
