Primeiro relato de platinossomose felina no município de Santa Maria - cura clínica e diagnóstico por colecistocentese

Abstract

Platinosomiasis is the main liver and bile duct verminosis in domestic cats. In Brazil, the cases are concentrated in the southeast and northeast regions, with few reports in the south of the country. The etiological diagnosis is usually obtained through the observation of eggs in the feces of the parasitized animal. A four-year-old male feline, mixed breed, with a history of jaundice, hyporexia and abdominal dilation, was referred for clinical care. The leukogram showed leukocytosis due to eosinophilia and serum biochemistry showed a marked increase in liver extravasation enzymes. On ultrasound examination, there was marked hepatomegaly and the presence of dilated, tortuous bile ducts, as well as severe fullness of the gallbladder. Furthermore, the coproparasitological examination proved to be inconclusive. The feline then underwent cholecystocentesis procedure in order to determine the etiology of the condition. The cytological examination of the bile fluid revealed parasitic structures with a morphology consistent with operculate eggs of Platinosomum spp. The diagnostic conclusion allowed the establishment of appropriate therapy in a timely manner, which enabled the resolution of the problem. This work reports the first case of feline platinosomosis in the city of Santa Maria/RS (Brazil) with clinical cure and etiological diagnosis via cholecystocentesis. It is therefore inferred that this investigative technique should be considered as an aid in the diagnosis of suspected cases of platinosomiasis.
