This study aimed at identifying the helminthfauna of Wild Boars (Sus scrofa scrofa). The study was developed between October 2001 and May 2002, with 51 animals of different ages and sex, from two private farms from the municipes of Mirassol and Fernandópolis, São Paulo State, Brazil. Group I (GI) had 18 animals ranging from 150 to 360 days old and GII, 33 ranging from 30 and 120 days old. Eight species of nematodes were identified from groups I and II, with the following prevalence: Trichuris suis (16.7% and 30.3%); Metastrongylus salmi (50.0% and 15.2%), Metastrongylus pudendotectus (5.6% and 3.0%); Strongyloides ransomi (27.8% and 12.1%); Ascaris suum (0.0% and 3.0%), Ascarops strongylina (27.8% and 0.0%); Physocephalus sexalatus (5.6% and 0.0%); Oesophagostomum dentatum (22.2% and 0.0%). There was a total of 7,958 nematodes identified, 6.573 from large intestine (82.6%), 1,246 in lungs (15.7%), 89 from small intestine (1.1%), and 50 in stomach (0.6%) The higher intensity variation was observed for T. suis (1 to 1.764), and M. salmi (1 to 248).
