We agree with Kemming et al.’s comments on Mycoplasma haemocanis and its effects on red cells in dogs. However, according to information from our University’s Center for the Control of Infections Diseases in Animals, the prevalence of M. haemocanis in kennel-raised dogs supplied to research laboratories in Botucatu, São Paulo, Brazil is very low. In addition, the dogs used in our study (1) were considered healthy after clinical examination and normal erythrocyte count—see the Methods section of our article. In addition, our study was carried out in acutely splenectomized dogs. As M. haemocanis is a red cell parasite that causes disease mainly in immunosuppressed or previously splenectomized dogs, we are confident that its influence was not underestimated in our study.
