Sistemática e interação parasito-hospedeiro de helmintos Phalacrocorax brasilianus e Cairina moschata domestica da reserva extrativista marinha de Soure, Ilha de Marajó, Pará.

Abstract

The Anseriforme order has as one of the representative Cairina moschata domestica, known as Muscovy duck of great economic importance, they have an aquatic habit, and most species are migratory to meet the needs of food, nesting, shelter, and molting. Brazil has few species of anatidae. The order Suliformes includes four families, whose representatives are found on all 39 continents, one of them being the Phalacrocorax brasilianus. Both live in a common environment on the Marajó Island, where there is a variable number of intermediate hosts that are part of the biological cycles of these birds’ parasites. Samples of C. moschata and P. brasilianus from Marajó Island, State of Pará, were analyzed. These samples will be obtained from dead birds in the domain of the local population. The parasitic helminths found will be processed for analysis by light microscopy, scanning electron microscopy, histology, and molecular biology. Catalogs, identification keys, books and scientific articles with original descriptions and species redescription will be used to identify the taxon. They will be counted, under a stereomicroscope, to determine the parameters of prevalence, mean infection intensity and mean abundance. Data will be tabulated and compared with data in the existing literature for each identified taxon. With this, we identified species of helminths, characterized the parasite-host relationship harmful to these birds, thus adding data on the parasite biodiversity of birds in northern Brazil.
