摘要: Twenty-nine Japanese wild boars (Sus scrofa leucomystax), collected during the hunting seasons of 2005 and 2006 in western part mainland Japan (Honshu), were examined for their visceral helminths. Eighteen helminth parasites prevalent them, including 17 Nematoda species (Metastrongylus elongatus, Metastrongylus salmi, asymmetricus, pudendotechus, Stephanurus dentatus, Gnathostoma doloresi, Physocephalus sexulata, Ascarops strongylina, Capillaria suis, Ascaris suum, Globocephalus samoensis, longimucronatus, Strongyloides ransomi, Trichuris Bourgelatia diducta, Oesophagostomum dentatum, watanabei), one Cestoda (Pseudanoplocephala nipponensis). Muscle digestion diaphragm (using an artificial gastric juice) 24 detected a single diplostomulum probably Pharyngostomum cordatum. In addition, four female six male adults Morgascaridia kugii sp. n. (Nematoda: Schneidernematidae) recovered from large intestine boar. Examination additional 20 samples stomach 27 could not find this species. To date, recorded genus are limited to M. sellsi Uganda Congo several decades ago, thence, no records recovery available. differed by smaller body dimensions, shorter distance between precloacal sucker cloaca, sizes copulatory spicules gubernaculum, uterine eggs.
