| two new species of litomosoides (nematoda: filarioidea) in sigmodontines (rodentia: muridae) from rio de la plata marshland, argentina. | two new species of coelomic filarioid belonging to litomosoides are described from sigmodontine murids from the rio de la plata marshland, argentina. litomosoides bonaerensis n. sp., a parasite of oligoryzomys delticola, belongs to the carinii group and is close to l. silvai, which differs by the head and tail papillae, buccal capsule and cavity, area rugosa, and morphology of the microfilaria. litomosoides oxymycteri n. sp., from oxymycterus rufus, belongs to the sigmodontis group. differential ... | 2000 | 11191910 |
| arthropod and filarioid parasites associated with wild rodents in the northeast marshes of buenos aires, argentina. | during 1995, 16 species of arthropods and 2 species of filarioids, totaling 1 287 specimens were collected from 64 wild rodents captured in the hudson natural reserve, buenos aires, argentina. infestation parameters and indexes were analyzed. host specific richness was s = 6, diversity h = 1.48, and relative density rdi = 40%. high values of parasite species richness and diversity were found on oligoryzomys delticola (s = 9; h = 1.40), oxymycterus rufus (s = 9; h = 1.37), and oligoryzomys flaves ... | 2003 | 12973536 |
