PARASITISMO POR Dioctophyme renale ENCONTRADO EM CÃES DE ABRIGOS DO MUNICÍPIO DE SÃO MATEUS DO SUL, ESTADO DO PARANÁ.

Dioctophyme renale is a zoonotic nematode that infects the kidneys of domestic and wild carnivores in Brazil. Among the dogs, it is highly prevalent in stray animals, mainly because of their less selective habits, making interesting the study with them. Shelter animals usually have a life background in a precarious and overpopulated environment with low access to good quality feed and water, which contributes to the spread of dioctophymosis. The objective of this work was to verify the occurrence of D. renale parasitism in shelters dogs from municipality of São Mateus do Sul, Paraná. Animals were transported by a non-governmental organization (NGO) to the Veterinary School Hospital for the procedure of total hysterectomy with bilateral salpingo-oophorectomy (HSO). The results of hematological, biochemical and urine analyses of parasitized and not parasitized dogs were compared using the Student t-test as well as age was evaluated by Fisher's exact test (p=0.05). From August to November 2018, the shelter sent 38 mixed-breed female dogs for HSO, and three (7,89%) of them presented eggs of the parasite in the urine. One of these three positive dogs died during the HSO procedure. A female of D. renale was found in the left kidney over the necropsy. Creatinine was significantly higher for those dogs presenting eggs of D. renale in the urine (p = 0.015). No differences were found for dogs with or without parasite eggs in the urine for the following factors: urea and total protein test, hemogram, leukogram, urinalysis, as well as age (p=0.05). It is possible to conclude that in dogs from this municipality, especially in shelter dogs, routine urinalysis and creatinine dosage levels, even for those apparently healthy, are important for an early diagnosis of parasitism by D. renale.
