| Abstract: | To determine the intensity of helminth infection and egg output with regard to age and sex of wild boar, stomachs and intestines of 124, lungs of 62, and livers of 39 animals from 5 enclosures in Southern Germany were examined. The evaluation of the intensity of infection showed 579.4 worms per animal for Hyostrongylus rubidus, 510.4 for Globocephalus longemucronatus, 476.9 for Oesophagostomum dentatum, 476.9 for O. quadrispinulatum, 254.2 for Metastrongylus pudendotectus, 176.9 for M. salmi, 140 for Physocephalus sexalatus, 56.9 for M. apri, 45.4 for Trichuris suis, and 3.3 for Ascaris suum. 33.6 liver flukes per infected wild boar were also found. Additionally 2 metacestodes of Taenia hydatigena on the serous liver coat of an adult sow were found. The worm burden with respect to age of the animals showed no or only minimal age related differences, whereas a large number of O. dentatum and O. quadrispinulatum was found in adults compared to younger wild boars. The evaluation of the intensity of infection with regard to sex of the animals showed higher values only for H. rubidus, O. dentatum, O. quadrispinulatum and P. sexalatus in males compared to female wild boars. The egg output intensity in the samples taken from the rectum was in average 3300 EpG for A. suum, 450.4 EpG for Oesophagostomum, 445.9 EpG for Globocephalus, 220 EpG for Trichuris, 207.9 EpG for Metastrongylus, 190.8 EpG for Hyostrongylus and 67 EpG for Capillaris. The egg output with respect to age showed higher values in younger wild boars than in adults. |
