Hemotropic Mycoplasma and Bartonella Species Diversity in Free-Roaming Canine and Feline from Luanda, Angola

Human coinfection with Bartonella henselae and two hemotropic mycoplasma variants resembling Mycoplasma ovis.

Two variants of an organism resembling the ovine hemoplasma, Mycoplasma ovis, were detected by PCR in blood samples from a veterinarian in Texas. Coinfection with similar variants has been described in sheep. This represents the first report of human infection with this organism. The veterinarian was coinfected with Bartonella henselae.
