Primeiro relato de parasitismo por Capillaria spp. em turu-turu / First report of parasitism by Capillaria spp. in Painted-billed crake

Dentre as principais afecções que acometem aves silvestres e que dificultam a conservação desses indivíduos, estão as endoparasitoses, que ganham destaque devido a sua alta prevalência. Dentro do filo Nematoda, Capillaria spp. é tido como um dos gêneros de endoparasitos de maior interesse sanitário no âmbito da medicina de aves, pois pode parasitar psitacídeos, passeriformes, columbiformes, galiformes e rapinantes. Portanto, a fim de favorecer dados ecológicos da relação parasito-hospedeiro demonstrada através deste estudo, o objetivo deste trabalho foi relatar, pela primeira vez no Brasil, a ocorrência de Capillaria spp. em N. erythrops olivascens. Os nematódeos deste gênero acometem, principalmente, o sistema respiratório e o trato gastrintestinal dos hospedeiros, causando inflamações e ulcerações nos locais de fixação, e ocasionando prejuízos à higidez dos animais. Uma das principais formas de diagnóstico é por meio do exame parasitológico das fezes dos animais acometidos e análise em microscopia óptica, onde pode-se observar a presença dos ovos. Assim, coletou-se fezes de um N. erythrops e encaminhou-se ao Laboratório de Parasitologia Animal da UFERSA. A coproparasitologia foi realizada por meio dos métodos de exame direto, flutuação com sulfato de zinco e OPG em câmara de McMaster, utilizando solução de cloreto de sódio a 0,9%. O animal foi tratado com ivermectina, mas percebeu-se que a utilização desse fármaco não surtiu efeito para a eliminação do parasito. A ocorrência desse Nematoda em N. erythrops, relatada pela primeira vez no Brasil, constitui um novo dado aplicável aos endoparasitos que ocorrem nessa espécie hospedeira.

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.

Parasitismo por Proatractis sp em jabuti piranga / Parasitism due to Proatractis sp. in red-footed tortoise

Tortoises are chelonians characterized by cylindrical and strong legs adapted to terrestrial life. These animals have gradually gained more space within the segment of wild animal pets. Parasitism is the relationship between living beings in which there is advantage to one species, parasite, and disadvantage to a greater or lesser degree to another, host. It may also be divided into endoparasitism or ectoparasitism if the parasite inhabits the interior of the host organism or only its outer surface, respectively. Atractidae is a family of endoparasites with direct cycle. Their eggs hatch in utero and third stage larvae are released. A male adult specimen of red-footed tortoise was treated in the Wild Animal Sector of the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital of the Federal Rural University of the Semi-Arid. During the physical examination the animal defecated and when inspecting its feces it was possible to observe with the naked eye the presence of large quantity of small helminths. Samples were collected and analyzed in an electron microscope through the direct examination technique through which it was possible to identify the parasite.(AU)
