Eighty fecal samples from free living wild boars and internal organs from eleven hunted animals from Bulgaria were investigated during 2016–2017. The fecal samples were analyzed with the coproscopical methods of Fulleborn, Shterbovich and serial sedimentations, as well as the modified Baermann technique. Helminthological necropsies of the lungs and gastrointestinal tracts of the animals were carried out through the common technique. Ten helminth genera (Metastrongylus, Strongyloides, Oesophagostomum, Hyostrongylus, Globocephalus, Nematodirus, Ascaris, Ascarops, Trichuris, Macracanthorhynchus) and one protozoa (Eimeria) were established through coproscopical investigations. Helminths of the species Metastrongylus elongatus, M. pudendotectus, M. salmi, Globocephalus urosubulatus, Oesophagostomum dentatum, O. quadrispinulatum, Trichuris suis, Macracanthorhynchus hirudinaceus, Ascaris suum, Ascarops strongylina and Physocephalus sexalatus were found during the necropsies. Metastrongylus, Globocephalus and Oesophagostomum were the genera with the highest prevalence of infection being respectively 28.75%, 13.75% and 12.5%. These were also the genera with the highest territorial incidence. Metastrongylids were found in eight of the eleven examined areas, while globocephalids and oesophagostomids were found in four of them. The infections of Metastrongylus spp., Oesophagostomum spp. and Ascarops spp. were with the highest intensity. This is the first study in which O. quadrispinulatum has been found in wild boar from Bulgaria.
2016年至2017年期间，对来自保加利亚的80份自由放养野猪的粪便样本以及11只被猎杀动物的内脏进行了调查。粪便样本采用富勒伯恩法、什捷尔博维奇法、连续沉淀法以及改良的贝尔曼技术进行显微镜检查分析。通过常规技术对动物的肺和胃肠道进行了蠕虫学尸检。通过显微镜检查确定了10个蠕虫属（后圆线虫属、类圆线虫属、食道口线虫属、猪圆线虫属、球首线虫属、细颈线虫属、蛔虫属、猪蛔状线虫属、毛首线虫属、巨吻棘头虫属）和1个原生动物（艾美耳球虫属）。尸检过程中发现了长后圆线虫、阴部后圆线虫、萨尔米后圆线虫、尾细球首线虫、有齿食道口线虫、四棘刺食道口线虫、猪毛首线虫、蛭形巨吻棘头虫、猪蛔虫、猪蛔状线虫和六翼泡首线虫等蠕虫种类。后圆线虫属、球首线虫属和食道口线虫属是感染率最高的属，分别为28.75%、13.75%和12.5%。这些也是地域发病率最高的属。在11个检查区域中的8个区域发现了后圆线虫，而在其中4个区域发现了球首线虫和食道口线虫。后圆线虫属、食道口线虫属和猪蛔状线虫属的感染强度最高。这是首次在保加利亚野猪中发现四棘刺食道口线虫的研究。
