Infection in domestic dogs (Canis lupus familiaris, Linnaeus, 1758) from Guaratuba, Parana, Brazil by circulating microfilariae of Acanthocheilonema reconditum (Grassi, 1889)

The epidemiologic frameworks of zoonosis periodically change in some of its aspects, involving the emergence or reemergence of men and animals' worsening of health. In this scenario, in which rapid changes can happen, the analysis of the prevalence of diseases, as the filariasis diagnosed in dogs from the coastline of Parana, has significant relevance. This study has been carried out with 422 dogs and aimed to determine the prevalence of circulating microfilariae of Acanthocheilonema reconditum, both in animals accommodated at the municipal kennels, as those that live in the district COHAPAR II, both places located in the metropolitan area of the city of Guaratuba-Parana, through two blood tests: evaluation of fresh blood, by the technique of the 'thick drop' and method of Knott modified by Newton and Wright. Thirty of the evaluated animals (7.10%), twenty two males and eight females, showed the presence of microfilariae of A. reconditum as result.
