Estudo de microfilarídeos patogênicos nas espécies mais abundantes de insetos hematófagos na grande Belém, Pa

Abstract

The filariases are diseases caused by worms known as filarids, belonging to the class Nematoda, whose adult forms parasitize the lymphatic system, abdominal cavity, and tissues of vertebrates. The young forms, called microfilariae, are found in the blood or skin, depending on the species. The human filarias species targeted in this study are Wuchereria bancrofti and Manzonella ozzerdt. The cycle of these filarias implies the existence of two hosts, the vertebrate and the invertebrate. The insects of the order diptera, potential vectors, that will be analyzed are: Carapanans (Culicidae), Maroons (Cerapatogonidae), Piuns (Simuliidae) and Mutuca (Tabanidae). The objective of this study is to survey and identify through morphology the filaridae, in their various stages in vector insects. We carried out bibliographic research in the libraries of the Museu Paraense Emílio Goeldi, of the Federal University of Pará (UFPA) and via the Internet, and visited public organs, the Municipal Health Secretariat, to collect data on the phylarids, such as: index of phylarids in recent years; methods of analysis and identification of phylarids in the vertebrate host; methods of collection, conservation and identification of phylarids in the invertebrate host. Participated in the course "Special Topics in Medical Helminthology" at the UFPA Tropical Medicine Center. Contacts with specialists from FIOCRUZ, Rio de Janeiro, UFPA and the Instituto Nacional de Pesquisas da Amazônia were made to define the techniques of collection, dissection and conservation of the material. The field collections will only be developed starting in May 2007, after the definition of the methodology. The results will be presented in the final report and in the oral presentation.
