Fig. 1From: Molecular and morphological characterization of three new species of avian Onchocercidae (Nematoda) with emphasis on circulating microfilariaeEufilaria acrocephalusi sp. n. from Acrocephalus scirpaceus (common reed warbler). a Female anterior extremity (live worm). b Male anterior extremity (ethanol-fixed). c Female anterior extremity (ethanol-fixed). d Male spicules (ethanol-fixed). e Microfilariae obtained from uterus (female was ethanol-fixed). f Live microfilaria in peripheral blood. g, h Microfilariae from peripheral blood (methanol-fixed, Giemsa-stained blood films). i Posterior part of microfilaria from peripheral blood (Giemsa-stained). Note that all microfilariae have a thread-like appearance (e–h). Width is a distinctive feature of this parasite.
