PREVALENCE AND INTENSITY OF DIGESTIVE AND PULMONARY PARASITES IN WILD BOARS IN ROMANIA.

The prevalence and intensity of infection with digestive, liver, and pulmonary parasites in wild boars in Romania was determined by examination of 280 cadavers from 26 hunting grounds during the period 2012-2016. Eleven genera of parasites were recovered: nine within the digestive system (Eimeria, Ascaris, Globocephalus, Gongylonema, Hyostrongylus, Oesophagostomum, Physocephalus, Trichuris, and Macracanthorinchus); and two (Dicrocoelium, Metastrongylus ) located in the hepatic and pulmonary systems. The overall prevalence of infection was 80.7% (n = 280). Polyparasitism was found in 82.8% of positive cases. The mean intensity of parasitism was highest for pulmonary parasites (Metastrongylus salmi, 25.95). Regarding gastrointestinal parasites, the highest mean intensity occurred in the case of Oesophagastomum dentatum infections (22.14), whilst the lowest was that of Macracanthorhynchus hirudinaceus (1.66). Wild boars are an important source of infection for domestic pigs in Romania and neighboring countries where extensive breeding systems occur.
