Sumario:The aims of this paper were to list the helminths from sympatric rodent species (Muroidea, Cricetidae) in Corrientes city, Humid Chaco ecoregion, Argentina and summarise the record and ecological data on six host species. Fourteen species of helminths were found in 6 rodent assemblages. Five new hosts and 12 new geographical reports from Humid Chaco ecoregion are provided. The higher prevalence values corresponded to Stilestrongylus stilesi, Hassalstrongylus mazzai, H. argentinus and Mazzanema fortuita, and the higher mean abundance and mean intensity values corresponded to S. stilesi from Necromys lasiurus. Nippostrongylinae was the dominant group within each host species. The ecological descriptors of component communities are given. The highest value of richness index was observed for N. lasiurus (S = 6). The diversity index reached values between the range 1.11 in Holochilus chacarius and 0.16 in Akodon azarae. The equitability index shows the highest values for Oligoryzomys flavescens (0.96) and H. chacarius (0.81). The highest value index of dominance of Berger-Parker was observed for A. azarae (0.96) followed by N. lasiurus (0.86). This study contributes to the taxonomic and ecological of the parasite-host relationships, providing substantial information to one of the ecoregions most affected by anthropic actions in Argentina.
