Resumen:
We investigated the parasite community (arthropods and filarioids) associated with wild rodents from a marshy
area in Buenos Aires province, Argentina. During 1995 and 1996, 105 sigmodontine rodents were trapped in The Reserva
Selva Marginal de Punta Lara and in La Balandra (Argentina). Six sigmodontine species with a relative density (RDI) of
11.1% were trapped. A total of 3,371 specimens from 16 species of arthropods and 2 species of filarioids were collected. The
values of parasite species richness (S) and prevalence (P) were as follows: from Scapteromys aquaticus S¼9; P¼96%, fromScapteromys aquaticus S¼9; P¼96%, from
Oligoryzomys spp. S¼8; P¼100%, from Oxymycterus rufus S¼8; P¼93%, and from Akodon azarae S¼6; P¼93%. The
single Deltamys kempi captured was not parasitized. Parasite communities of S. aquaticus and Ox. rufus showed the highest
similarity resulting from their overlapped microhabitats, not only when presence/absence of species was considered
(Sorensons index; Css ¼82%), but also when the proportion of every species was taken into account (Piankas index; O ¼

26.67). The 2 species of filarioids collected were restricted to Oligoryzomys spp. and Ox. rufus. The absence of lice and
filarioids from Ox. rufus from La Balandra suggests an isolation of this host population from the northern localities.
