Gastrointestinal parasites in captive and free-living wild birds in Goiania Zoo / Parasitas gastrointestinais em aves silvestres em cativeiro e de vida livre no Zoológico de Goiânia

Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The main interest of this study is to report the occurrence of eggs and oocysts in feces from captive wild birds in Goiânia Zoo and free-living birds in its surroundings. The fecal samples were subjected to parasitological examination to identify the presence of helminths and to classify their eggs based on morphological characteristics. Eggs of nematode parasites (Positive/N) were identified as Ascaridia spp. in Brotogeris chiriri (2/2), Dromaius novaehollandiae (1/1) and Rhea americana (2/2); Ascarididae in Pavo cristatus nigripensis (1/1); Capillaria spp. in Ara chloropterus (1/1) and Penelope jacucaca (1/1); Capillaria plagiaticia in Anodorhynchus hyacinthinus (1/2) and Ara spp. (2/2); Capillaria venusta in Rhamphastus tucanus (1/2); and unidentified nematode eggs from Amazona amazonica (2/2). Eimeria spp. oocyst was founded in feces from A. hyacinthinus (1/2). Considering free-living birds, Diphyllobothrium spp. eggs were founded in Ardea alba (2/2) and Nycticorax nycticorax (2/3). Co-infection of Eustrongylides spp. was founded in A. alba (1/2). This is the first occurrence of: Ascaridia spp. parasitizing B. chiriri; and C. venusta parasitizing R. tucanus. In conclusion, the helminth eggs found in the abovementioned host bird species are consistent with those reported in the literature, and treatment and control protocols were based on their identification.

As infecções por endoparasitas podem causar doenças graves, podendo matar aves em cativeiro e representam um problema de manutenção e conservação. Os ovos e as formas larvais desses parasitas são geralmente eliminados nas fezes do hospedeiro. O principal objetivo deste estudo é relatar a ocorrência de ovos e oocistos em fezes de aves silvestres em cativeiro no Zoológico de Goiânia e em aves de vida livre em seu entorno. As amostras fecais foram submetidas a exame parasitológico para identificação da presença de helmintos e classificação dos ovos com base nas características morfológicas.

Oocistos de Eimeria spp. foram encontrados nas fezes de A. hyacinthinus (1/2). Considerando pássaros de vida livre, ovos de Diphyllobothrium spp. foram encontrados em Ardea alba (2/2) e Nycticorax nycticorax (2/3).
