Prevalencia De Un Parásito Zoonótico, Dioctophyma Renale (Goeze, 1782), en Caninos Machos De Una Zona Rivereña Al Río De La Plata, Provincia De Buenos Aires, República De Argentina.

Abstract

Dioctophymosis is an helminthiasis with an indirect life cycle caused by Dioctophyma renale. It may affect both humans and other mammals. The purpose of this study was to determine the prevalence of the parasite in male canines of different ages, living in a wild riverside area of La Plata River with favourable characteristics for the development of eggs, intermediate or paratenic hosts and completionof the life cycle of D. renale. 171 animals were surveyed and samples were collected through urethral catheterization. The samples were processed by means of centrifugation at a relative centrifugal force of 700 g and microscopic observation of sediments. 42.1% of canines exhibited patent Dioctophymosis in their kidneys. Male canines between the ages of 2 and 5 showed the highest frequency of positive results. Several epidemiological risk factors are discussed that, when associated, might favour the high prevalence of this parasite in the area. The need for equipment for the indirect diagnosis of the disease in canines and other animals prone to infection is clearly demonstrated.

First report of Dioctophyma renale (Nematoda, Dioctophymatidae) in Colombia

“…In Brazil, cases have been reported in several states, including Rio Grande do Sul (3,(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). Similarly, the canine dioctophymosis has been reported in various regions of Argentina (10,(21)(22)(23)(24)(25)(26) and Uruguay (27,28).…”

“…Dioctophyma renale is commonly described in dogs. Brazil and Argentina are the countries with the largest number of reported cases in mammals (5,10). In Brazil, cases have been reported in several states, including Rio Grande do Sul (3,(11)(12)(13)(14)(15)(16)(17)(18)(19)(20).…”

Comprobación experimental del ciclo biológico de <i>Dioctophyma renale</i>, en un área ribereña al río de la Plata

“…El material se procesó convenientemente, así se logró disponer de abundante material parasitario (huevos) para poder realizar la totalidad de observaciones, mediciones y ensayos. A continuación, se listan los procedimientos realizados con el mismo (Burgos et al, 2015).…”
