Hemoplasma in Cats (formerly Hemobartonella)

Sykes, J. E., J. C. Terry, et al. (2008). “Prevalences of various hemoplasma species among cats in the United States with possible hemoplasmosis.” J Am Vet Med Assoc 232(3): 372-9.

Three species of hemoplasmas are known to infect cats, the most well known of which is Mycoplasma haemofelis (formerly Hemobartonella felis). M. haemofelis is associated with hemolytic anemia in some infected cats. Two other hemoplasmas, M. haemominutum and M. turicensis, are less commonly associated with clinical disease. In this study, 310 blood samples that had been submitted to a commercial laboratory because the cats had anemia and/or they were suspected of having hemoplasmosis were evaluated with species-specific PCR assays. The prevalences were 23.2% for M. haemominutum, 4.8% for M. haemofelis, and 6.5% for M. turicensis. Male cats were more likely to be infected with hemoplasmas, and FeLV and FIV were strongly associated with M. haemofelis infection. The results of this study show that these hemoplasmas occur commonly in cats in the United States.
