Cytauxzoon felis is a hemoparasite capable of infecting domestic and wild cats. Studies suggest that wild cats are the main reservoirs of the protozoan, and transmission occurs through the bite of an infected tick. Hemotropic mycoplasmas are Gram-negative bacteria responsible for severe hemolytic anemia. The feline immunodeficiency virus (FIV) is a retrovirus capable of generating immunosuppression in the host and persistent infection. The present work describes a case of co infection of Cytauxzoon felis, Mycoplasma haemofelis, and feline immunodeficiency virus (FIV) in a cat. A feline from the rural area was admitted to the Veterinary Hospital of Uberlândia - MG of the Federal University of Uberlândia. Fresh whole blood samples were collected for blood count, enzymatic analysis, DNA extraction, real-time PCR for the detection of Cytauxzoon felis and Mycoplasma haemofelis, and the Point of Care ELISA test for Feline Leukemia Virus (FeLV) antigens and antibodies to feline immunodeficiency virus (FIV). Piroplasms compatible with Cytauxzoon spp. were observed in the smear, and the tests performed were positive for Cytauxzoon felis, Mycoplasma haemofelis, and FIV.
