Twenty-nine Japanese wild boars (Sus scrofa leucomystax), collected during the hunting seasons of 2005 and 2006 in the western part of the mainland of Japan (Honshu), were examined for their visceral helminths. Eighteen helminth parasites were prevalent in them, including 17 Nematoda species (Metastrongylus elongatus, Metastrongylus salmi, Metastrongylus asymmetricus, Metastrongylus pudendotechus, Stephanurus dentatus, Gnathostoma doloresi, Physocephalus sexulata, Ascarops strongylina, Capillaria suis, Ascaris suum, Globocephalus samoensis, Globocephalus longimucronatus, Strongyloides ransomi, Trichuris suis, Bourgelatia diducta, Oesophagostomum dentatum, and Oesophagostomum watanabei), and one Cestoda species (Pseudanoplocephala nipponensis). Muscle digestion of the diaphragm (using an artificial gastric juice) of 24 wild boars detected a single diplostomulum of probably Pharyngostomum cordatum. In addition, four female and six male adults of Morgascaridia kugii sp. n. (Nematoda: Schneidernematidae) were recovered from the large intestine of a single wild boar. Examination of an additional 20 samples of the stomach and 27 samples of the large intestine could not find this species. To date, recorded species of the genus Morgascaridia are limited to M. sellsi collected from wild boars in Uganda and Congo several decades ago, and thence, no records of the recovery are available. Morgascaridia kugii sp. n. differed from M. sellsi by smaller body dimensions, shorter distance between the precloacal sucker and the cloaca, smaller sizes of the copulatory spicules and the gubernaculum, and smaller sizes of uterine eggs.
2005年和2006年狩猎季节期间，在日本本州岛大陆西部采集了29头日本野猪（野猪指名亚种），对其体内的蠕虫进行了检查。其中有18种蠕虫寄生虫，包括17种线虫（长后圆线虫、萨尔米后圆线虫、不对称后圆线虫、阴部后圆线虫、有齿冠尾线虫、多氏颚口线虫、六翼泡首线虫、强壮蛔状线虫、猪毛细线虫、猪蛔虫、萨摩亚球首线虫、长尖球首线虫、兰氏类圆线虫、猪鞭虫、双管布尔吉线虫、有齿食道口线虫、渡边食道口线虫）和1种绦虫（日本假裸头绦虫）。对24头野猪的膈肌进行肌肉消化（使用人工胃液），检测到1条可能是心形咽口线虫的双腔蚴。此外，在1头野猪的大肠中发现了4只雌性和6只雄性的新种库氏莫加斯卡线虫（线虫纲：施奈德线虫科）。对另外20份胃样本和27份大肠样本进行检查，未发现该物种。迄今为止，莫加斯卡线虫属记录的物种仅限于几十年前在乌干达和刚果从野猪体内采集到的塞尔氏莫加斯卡线虫，此后再无该物种检出的记录。库氏莫加斯卡线虫与塞尔氏莫加斯卡线虫的区别在于体型较小、泄殖腔前吸盘与泄殖腔之间的距离较短、交合刺和引带尺寸较小以及子宫内虫卵尺寸较小。
