Plain-English summary
A group of dogs in southern Brazil was tested for a type of bacteria called hemoplasmas, which can infect red blood cells and cause health issues. Out of 331 dogs, 17 tested positive for Mycoplasma haemocanis, and 6 had a related type of bacteria. Older dogs, those with dog bite wounds, and dogs with cancer were found to be at higher risk for these infections. The study suggests that having certain diseases, like cancer, may increase the likelihood of hemoplasma infection. Treatment options were not detailed, but identifying the infection is crucial for managing the health of affected dogs.

Abstract
Hemoplasmas are ubiquitous pleomorphic and epicellular bacteria detected in erythrocytes in several species. In Brazil, studies on hemoplasmas have not included information on occurrence, clinical signs, and risk factors in dogs. This paper investigates the occurrence of hemoplasmas in dogs, focusing on risk factors and clinical status. Conventional PCR for the four types of canine hemoplasmas was performed in 331 blood samples collected from dogs clinically treated at a teaching veterinary hospital. Of all samples, 17/331 (5.1%) were positive for Mycoplasma haemocanis and 6/331 (1.8%) were positive for a 'Candidatus Mycoplasma haemominutum-like' organism. Risk factors included the presence of vectors, old age, dog bite wounds, and neoplastic diseases. In the multivariate analysis, a 4.40 odds ratio in dogs with vector-borne diseases indicated risk for hemoplasmosis. There was correlation between hemoplasma infection and neoplastic disease, suggesting that neoplastic conditions are a risk factor for hemoplasma infection in dogs.
