Sus scrofa
Wild boars are known to host at least 20 different parasitic worm species, with maximum infections occurring in summer. Young animals are vulnerable to helminths like "Metastrongylus", which are consumed by boars through earthworms and cause death by parasitising the lungs. Wild boar also carry parasites known to infect humans, including "Gastrodiscoides", "Trichinella spiralis", "Taenia solium", "Balantidium coli" and "Toxoplasma gondii". Wild boar in southern regions are frequently infested with ticks ("Dermacentor", "Rhipicephalus", and "Hyalomma") and hog lice. The species also suffers from blood-sucking flies, which it escapes by bathing frequently or hiding in dense shrubs.
