Prevalence of lung worms belonging to the genus Metastrongylus was surveyed on 42 Japanese wild boars (Sus scrofa leucomystax) captured officially for wildlife damage control in the western parts of Tokyo, Japan from April 2000 to April 2001. The number of parasites was the highest in the caudal lung lobes. Four species, M. elongatus (ME), M. salmi (MS), M. asymmetricus (MA) and M. pudendotectus (MP), were identified. All the boars were infected with 2 or more species, and 64.3% of the boars had all 4 species. The composition of species, ME:MS:MA:MP=1.3:3.4:1.0:1.4, was drastically different from the previous reports. The peak of the average number of the parasites was observed in the period of January to March 2001 because of the increase of MS.
2000年4月至2001年4月期间，对在日本东京西部因野生动物损害控制而正式捕获的42头日本野猪（野猪指名亚种）进行了圆线属肺线虫的流行情况调查。寄生虫数量在肺尾叶中最高。鉴定出四种线虫，即长刺圆线虫（ME）、萨尔米圆线虫（MS）、不对称圆线虫（MA）和阴刺圆线虫（MP）。所有野猪都感染了两种或更多种线虫，64.3%的野猪感染了全部四种线虫。线虫种类的构成比例为ME:MS:MA:MP = 1.3:3.4:1.0:1.4，与之前的报告有很大不同。由于MS数量的增加，2001年1月至3月期间观察到寄生虫平均数量的峰值。
