The aim of this study was to describe the infection levels of helminths of Rattus rattus in Corrientes city, Corrientes province, Argentina. In order to determine the role of rodents as potential reservoirs for zoonotic parasites, different indices of helminthes were compared with respect to sex, age, season and urban landscapes. A total of 107 individuals of R. rattus were examined. Seven species of helminthes (S=7) were found. The values of total prevalence, mean intensity and mean abundance were 68%, 20 and 13, respectively. Nippostrongylus brasiliensis were the specie more prevalent and abundant. The results showed that the age of the rodents (x2 = 39 df= 1, p= 0.00 and Bootstrap p-value= 0.02) and season (x2 = 3.8 df= 1, p= 0.04) has effects on the helminth infection.
