Abstract The objective of the present study was to identify the intestinal parasites with the highest prevalence in anatids that were reared extensively in the city of São Paulo, through coproparasitological examinations. Fecal samples (n=108) were collected at two times, with an interval of two months between them, during the year 2018. The samples were constituted from a pool of feces, and one sample was collected from each enclosure. The samples were identified as belonging to 13 species of anatids (Aix galericulata, Aix sponsa, Anser abyssinia, Chenonetta jubata, Chloephaga melanoptera, Chloephaga picta, Lophodytes cucullatus, Tadorna cana, Tadorna ferrugínea, Tadorna radjah, Tadorna tadorna, Tadorna tadornoide and Tadorna variegata). Samples of birds with or without clinical symptoms of endoparasitosis were then collected. The Coproplus® test was used to make the coproparasitological diagnosis and subsequently the material was examined individually, at Santo Amaro University in São Paulo. It was observed that 48.14% of the enclosures had birds infected by one or more endoparasites. Parasites of the order Coccidia presented the highest prevalence (22.22%), followed by those of the orders Trichuroidea (10.18%) and Ascaridia (4.63%). Moreover, Balantidium sp. was found, the cycle and relevance of these ciliates in birds is uncertain.

Lophodytes Cucullatus

El mergo cresta blanca (Lophodytes cucullatus) es una especie de la familia Anatidae restringida a Norteamérica. La distribucióninvernal reconocida en México es una franja territorial de aproximadamente 50 km al sur de la frontera con EUA, en los estados de Baja California, Sonora, Coahuila, Nuevo León y Tamaulipas, siendo considerada poco común o accidental en el resto del país. Aquí, reportamos el primer avistamiento de la especie en el estado de Zacatecas. Si bien el mergo cresta blanca ha sido registrado previamente en áreas cercanas, éste es el primer registro dentro de los límites políticos de Zacatecas, con lo cual se incrementa el listado estatal de especies de aves confirmadas, así como el área donde es posible hallar a esta especie en México.
