Infecção por Mycoplasma spp. em um cão Labrador Retriever – relato de caso

Abstract

Mycoplasma haemocanis and Candidatus mycoplasma haematoparvum are canine mycoplasma species that can induce anemia in immunocompromised and / or splenectomized dogs. Transmission occurs through the bite of blood-sucking arthropods (fleas and ticks), blood transfusion, and / or contaminated and transplacentally infected interferences. Clinical signs include mucosal pallor, with or without jaundice, apathy, splenomegaly, and thrombocytopenia. Therapy previously instituted with doxycycline is generally effective in immunocompetent animals or without severe disease and has been proposed to have an additional benefit because it is anti-inflammatory. In animals with mixed infections by gram-negative organisms or with suspected tetracycline-resistant strains, fluoroquinolones may be good alternative antibiotic options. Techniques based on polymerase chain reaction (PCR) have been used to better understand the disease, as well as to evaluate the success of the therapy undertaken. Therefore, the objective of this work is to describe a case of mycoplasmosis in a canine male, labrador retriever, at eleven years old, which developed two weeks after splenectomy due to hemoperitoneum. It is concluded that mycoplasmosis should be included in the differential diagnosis of anemia in immunocompromised and / or splenectomized dogs.
