First report of parasitism by Capillaria spp. in Painted-billed crake
Keywords:
Parasitology, gruiform, coproparasitologicalAbstract
Among the main conditions that affect wild birds and hinder the conservation of these individuals are the endoparasitic diseases, that stand out due to their high prevalence. Within the phylum Nematoda, Capillaria spp. is considered as one of the endoparasites genera which is of great health interest in the field of poultry medicine, since it can parasitize parrots, passerines, pigeons, galliforms and predators. Therefore, in order to provide ecological data on the parasite-host relationship demonstrated through this study, the objective of this paper was to report, for the first time in Brazil, the occurrence of Capillaria spp. in N. erythrops olivascens. Nematodes of this genus mainly affect the respiratory system and gastrointestinal tract of the hosts, causing inflammation and ulcerations at the sites of attachment, causing damage to the animals' health. One of the main forms of diagnosis is through parasitological examination of the feces of affected animals and analysis under optical microscopy, where the presence of eggs can be observed. Feces were collected of a N. erythrops and sent to the Laboratory of Animal Parasitology at UFERSA. Coproparasitology was performed by direct examination, flotation with zinc sulfate, and OPG in a McMaster chamber, using 0.9% sodium chloride solution. The animal was treated with ivermectin, but it was noticed that the use of this drug had no effect on the elimination of the parasite. The occurrence of this Nematoda in N. erythrops is reported for the first time and constitutes a new data applicable to the entoparasites that occur in this host species in Brazil.
