Prevalence of two species of Litomosoides (Nematoda: Filarioidea) parasites of Akodon cursor (Rodentia: Muridae) from southeastern Brazil

Two species of filariids, Litomosoides silvai and Litomosoides chagasfilhoi, were collected from the thoracic and abdominal cavities, respectively, of Akodon cursor, from Catimbau Grande, Rio Bonito, Rio de Janeiro, Brazil. Fifty-eight rodents were necropsied and 15 (25.9) were parasitized. Four of the 15 infected rodents (26.7) presented concurrent infections, but each species had separate and specific sites of infection. This is the first report of a rodent species parasitized with naturally occurring, concurrent infections with two species of filarial worms.
