Resumo(s)
Uma cadela American Staffordshire Terrier de dois anos e meio foi apresentada à clínica
veterinária com história de quatro dias de anorexia, letargia e febre persistente. O exame físico revelou
mucosas pálidas, temperatura alta e discreto emagrecimento. A análise hemato-bioquímica
evidenciou uma anemia regenerativa hemolítica normocítica normocrómica moderada,
trombocitopenia severa com volume plaquetário médio aumentado, e neutropenia. O esfregaço
sanguíneo revelou a presença de formas intraeritrocitárias de grandes dimensões compatíveis com
Babesia spp. O teste rápido foi negativo para Anaplasma spp., Ehrlichia spp., Borrelia burgdorferi e
Dirofilaria immitis. Com base nos dados clínicos e laboratoriais, foi estabelecido o diagnóstico de
babesiose canina aguda. O tratamento consistiu na administração de dipropionato de imidocarbe,
suporte hepático com silimarina, fluidoterapia e antiparasitário externo. A evolução clínica foi
favorável, com normalização do apetite e da temperatura em menos de uma semana. No dia 14, os
exames laboratoriais mostraram recuperação dos parâmetros hematológicos e bioquímicos, sem
complicações ou recaídas. Este caso reforça a importância do diagnóstico precoce, do controlo eficaz
de vetores e da vigilância epidemiológica em regiões emergentes como o nordeste de França.
An American Staffordshire Terrier female dog, two and a half years old, was presented to the veterinary clinic with a four-day history of lethargy, anorexia, weakness, and persistent fever. Physical examination revealed pale mucous membranes, elevated body temperature, and mild weight loss. Hematological and biochemical analysis showed moderate normocytic normochromic hemolytic and regenerative anemia, severe thrombocytopenia with increased mean platelet volume, and neutropenia. A blood smear revealed large intraerythrocytic forms consistent with Babesia spp. The rapid test was negative for Anaplasma spp., Ehrlichia spp., Borrelia burgdorferi, and Dirofilaria immitis. Based on clinical and laboratory findings, a diagnosis of acute canine babesiosis was established. Treatment included administration of imidocarb dipropionate, hepatic support with silymarin, fluid therapy, and external antiparasitic treatment. Clinical evolution was favorable, with normalization of appetite and temperature within a week. On day 14, laboratory tests showed recovery of hematological and biochemical parameters, with no complications or relapses. This case highlights the importance of early diagnosis, effective vector control, and epidemiological surveillance in emerging regions such as northeastern France.
