[Cruorifilaria tuberocauda (Nematoda: Filarioidea) in Venezuelan capybaras]

Four filariae are known to parasitize the capybara "Hydrochoerus hydrochaeris" namely the "Cruorifilaria tuberocauda", Eberhard, Morales & Orihel (1976). The "Dipetalonema (Alafilaria) hydrochoerus", Yates (1983), and two "mansonella" recently described by Eberhard, Campo-Aasen & Orihel (1983), "Mansonella longicapita" and "Mansonella rotundicapita". In this study we describe the adult parasites and the microfilaria of the "Cruorifilaria tuberocauda" (Nematoda, Filarioidea), Eberhard, Morales & Orihel (1976) obtained from the arteries of the kidney of two capybaras from Apure and Barinas states of Venezuela. The pathology produced by the presence of the filariae in kidney and lungs of the animals is described as well as the blood harboring microfilaria.
