ABSTRACT

Descrevem-se os achados clínicos, laboratoriais e histopatológicos de feo-hifomicose sistêmica em um cão. Clinicamente observou-se cansaço, ascite, apatia, hiporexia, perda de peso e polidipsia. O animal estava sendo tratado para erliquiose e babesiose. Após 11 dias, o cão retornou com hepatopatia grave e veio a óbito em 48 horas. Na necropsia, observaram-se nódulos enegrecidos em vários órgãos da cavidade abdominal. Histologicamente, havia reação granulomatosa necrosante com hemorragia, associada a miríades de hifas fúngicas pigmentadas intralesionais em múltiplos órgãos, caracterizando feo-hifomicose sistêmica. Ressalta-se a importância de incluir esta doença no diagnóstico diferencial de hepatopatias graves em cães com ascite.


The objective of this study was to describe clinical, laboratorial and histopathological findings of systemic phaeohyphomycosis in a dog. The animal was presented with a history of fatigue, ascites, lethargy, weight and appetite loss and polydipsia. The therapy for erliquiose and babesiosis was started. After 11 days, the dog returned with severe liver disease and died after forty-eight hours. At necropsy, there were black nodules in various abdominal organs. Histologically, necrotizing granulomatous reaction with hemorrhage associated with myriads of intralesional pigmented fungal hyphae was observed in multiple organs, characterizing systemic phaeohyphomycosis. Thus, it is important to include this illness in the differential diagnosis of severe liver diseases in dogs with ascites.

ABSTRACT

Com o objetivo de determinar a soroprevalência da infecção por Ehrlichia canis, bem como identificar fatores de risco associados à soropositividade, foi realizado um inquérito sorológico em 109 cães atendidos no Hospital Veterinário/Centro de Saúde e Tecnologia Rural (CSTR)/Universidade Federal de Campina Grande(UFCG), Campus de Patos, Estado da Paraíba. O diagnóstico sorológico da erliquiose foi realizado por meio da reação de imunofluorescência indireta (RIFI) e as amostras que apresentaram títulos de anticorpos > 40 foram consideradas positivas. Das 109 amostras, 72,5% foram positivas (IC 95% = 63,1% – 80,6%). Animais que tiveram contato com cães (odds ratio = 3,59; IC 95% = 1,41 – 9,12), contato com açudes (odds ratio = 8,39; IC 95% = 1,01 – 69,87) ou com algum acesso à rua (odds ratio = 6,24; IC 95% = 1,28 – 30,39) estiveram mais expostos ao risco de infecção.


Aiming to determine the seroprevalence of Ehrlichia canis infection, as well as to identify risk factors associated to the seropositivity, a serological survey was conducted in 109 dogs assisted at the Hospital Veterinário/Centro de Saúde e Tecnologia Rural (CSTR)/Universidade Federal de Campina Grande (UFCG), Campus de Patos, Paraíba State, Northeastern Brazil. Serological diagnosis of ehrlichiosis was performed by the indirect fluorescent antibody test (IFAT) and sera presenting antibody titers > 40 were considered positive. Of the 109 samples, 72.5% were positive (95% CI = 63.1% – 80.6%). Animals that had contact with other dogs (odds ratio = 3.59; 95% CI = 1.41 – 9.12), contact with ponds (odds ratio = 8.39; 95% CI = 1.01 – 69.87) or with free access to the street (odds ratio = 6.24; 95% CI = 1.28 – 30.39) were more exposed to the risk of infection.
