"Candidatus Mycoplasma haemominutum" infections in 21 client-owned cats.

Abstract

Medical records were reviewed for 21 clinically ill cats testing positive for deoxyribonucleic acid (DNA) of "Candidatus Mycoplasma haemominutum" in their blood. Fever, anorexia, lethargy, and anemia were among the most common abnormalities recorded. Thirteen cats were anemic; seven had evidence of other diseases that could have been the primary cause of anemia or activated hemoplasmosis. For six cats, "Candidatus Mycoplasma haemominutum" was the only recognizable cause of the anemia. Of these cats, anemia resolved in one cat without treatment and in three cats that were treated with doxycycline, with or without prednisone. Results of the study suggest that this hemoplasma species can be a primary pathogen in cats.
