Canids filarids parasites belong to the Onchocercidae Family and are represented mainly by Genus Acanthocheilonema, Dipetalonema and Dirofilaria. These filarids develop in different places in the vertebrate host, and need for haematophagus invertebrate host to complete your cycle. Different infection levels can occur, since assintomatic, until the death of dog. The filarids parasites of dogs are found mainly in the region between the tropics. In the Amazon region a little is known about the distribution of these parasites, and until this moment, a study of distinguishing diagnosis was not performed. With this objective, we choose two cities in the Marajó Island (Salvaterra and São Sebastião da Boa Vista) and carry through a epidemiologic, morphologic and molecular studies. The percentage of microfilaremics dogs was of 37.34% in Salvaterra and 6.67% in São Sebastião da Boa Vista, resulting in a total prevalence of 32.45%. Analyzing the morphologic characteristics of the collected adult filarids, we concluded that these worms are of the Dirofilaria immitis species. For analysis of genic region, we conclude that the microfilariaes found in the dogs blood studied are also D. immitis species, and that these dogs had not presented mixing infection.porAcesso AbertoDoenças transmissíveisDirofilarioseEpidemiologiaDirofilária immitisSalvaterra - PASão Sebastião da Boa Vista - PAIlha de Marajó - PAPará - EstadoAmazônia brasileiraTeseCNPQ::CIENCIAS BIOLOGICAS::PARASITOLOGIA
