Description Filarid nematodes are transmitted by arthropod vectors. In the vertebrate host, they inhabit the cardiovascular, pulmonary, and lymphatic system. Although most bird infections are not considered pathogenic, there may be an impact on fitness. Blood smears were performed to verify the intensity of the infection and to morphometrically analyse and describe the microfilariae found in individuals of Antilophia galeata captured in a fragment of the Cerrado forest. The microfilariae were photographed, and morphometry analysis was performed using the ImageJ software. One individual was infected (14.2%; n = 7) but with a high intensity of infection (42 microfilariae). It is suggested that the microfilariae found belong to the genus Eufilaria spp., since all specimens presented the diagnostic characteristics of the taxon (absence of sheath, pointed tail, and length less than 200 μm). This is the first time that microfilariae parasitising A. galeata have been recorded. Considering that microfilariae records are rare in Brazilian wild birds, this record may be useful to support further studies and contribute to the understanding of the conservation of the host species.
Nematódeos filarídeos são transmitidos por vetores artrópodes. No hospedeiro vertebrado, habitam o sistema cardiovascular, pulmonar e linfático. Embora a maioria das infecções em aves não seja considerada patogênica, pode haver impactos no fitness. Os objetivos do estudo foram verificar a intensidade de infecção e descrever as microfilárias encontradas em Antilophia galeata. Sete indivíduos foram capturados em um fragmento florestal de Cerrado, para coleta de sangue e confecção de extensões sanguíneas. As microfilárias foram fotografadas e foi feita a morfometria através do software ImageJ. Um indivíduo estava infectado (14,20%), mas com alta intensidade de infecção (42 microfilárias). As microfilárias encontradas pertencem ao gênero Eufilaria spp., pois todos os espécimes apresentaram as características diagnósticas do táxon (ausência de bainha, cauda pontiaguda, e comprimento menor que 200 μm). Pela primeira vez foram registradas microfilárias parasitando A. galeata. Considerando que são raros os registros de microfilárias em aves silvestres brasileiras, este registro pode ser útil para subsidiar estudos posteriores e contribuir para o entendimento da conservação da espécie hospedeira.
