Six nematode, three cestode and five trematode species were identified in 30 capybara specimens (Hydrochoerus hydrochaeris hydrochaeris L., 1766). The species of greater prevalence were: Protozoophaga obesa (96.66%), Viannella hydrochoeri (93.33%), Hydrochoerisnema anomalobursata (90.0%), F.I. P. obesa (80.0%), Taxorchis schistocotyle (76.66%), Hippocrepis hippocrepis (70.0%), Capillaria hydrochoeri (63.33%), F.I. (Viannella + Hydrochoerisnema) (60.0%), Strongyloides chapini (56.66%), Monoecocestus macrobursatum (56.66%), F.I. Monoecocestus (46.66%), M. hydrochoeri (23.33%) and M. hagmani (23.33%). On the other hand, Trichostrongylus axei, Neocotyle neocotyle, Nudacotyle valdevaginatus and N. tertius occurred at lower levels. The total of helminths identified in the 30 animals was of 236,097 being verified 110 (0.05%) specimens in the stomach, 49,240 (20.85%) in the small intestines, 186,747 (79.10%) in the large intestines. The higher intensity variation were obtained by P. obesa, F.I. P. obesa, F.I. (Viannella + Hydrochoerisnema); V. hydrochoeri, S. chapini e N. valdevaginatus, with a mean of 3,900.0 (04-20,885), 2,958.1 (40-18,130), 689.7 (05-7,515), 601.5 (10-4,585), 765.3 (05-4,055) and 1,270.0 (0-1,270) worms per animal, respectively. V. hydrochoeri and S. chapini are the most pathogenic species, with clinical and subclinical parasitosis in capybara.
