Natural infection by sp. has been reported in humans and more than 150 species of animals, especially carnivorous and omnivorous mammals. Although the presence of sp. infection in wild boars () has been documented worldwide, limited information is known about circulation in farmed wild boars in China. This study intends to investigate the prevalence of sp. in farmed wild boars in China. Seven hundred and sixty-one (761) muscle samples from farmed wild boars were collected in Jilin Province of China from 2017 to 2020. The diaphragm muscles were examined by artificial digestion method. The overall prevalence of in farmed wild boars was 0.53% [95% confidence interval (CI): 0.51–0.55]. The average parasite loading was 0.076 ± 0.025 larvae per gram (lpg), and the highest burden was 0.21 lpg in a wild boar from Fusong city. was the only species identified by multiplex polymerase chain reaction. The 5S rDNA inter-genic spacer region of was amplified and sequenced. The results showed that the obtained sequence (GenBank accession number: OQ725583) shared 100% identity with the HLJ isolate (GenBank accession number: MH289505). Since the consumption of farmed wild boars is expected to increase in the future, these findings highlight the significance of developing exclusive guidelines for the processing of slaughtered farmed wild boar meat in China.
已有报道称,[某物种]在人类以及150多种动物中存在自然感染情况,尤其是食肉和杂食性哺乳动物。尽管在全球范围内都已记录到野猪感染[该物种],但关于其在中国养殖野猪中的传播情况,所知信息有限。本研究旨在调查中国养殖野猪中[该物种]的感染率。2017年至2020年期间,在中国吉林省采集了761份养殖野猪的肌肉样本。通过人工消化法对膈肌样本进行检测。养殖野猪中[该物种]的总体感染率为0.53% [95%置信区间(CI):0.51–0.55]。平均寄生虫负荷为每克0.076±0.025条幼虫(lpg),最高负荷出现在抚松市一头野猪身上,为0.21 lpg。通过多重聚合酶链反应鉴定出[该物种]是唯一检出的物种。扩增并测序了[该物种]的5S rDNA基因间隔区。结果显示,获得的序列(GenBank登录号:OQ725583)与[该物种]HLJ分离株(GenBank登录号:MH289505)的序列100%相同。鉴于未来养殖野猪的消费量预计会增加,这些发现凸显了在中国制定专门的屠宰养殖野猪肉加工指南的重要性。
