Abstract
Living larvae were collected in central Italy from the masseters of a wolf frozen for 6 mo. These parasites were identified as a southern Palearctic species (Trichinella sp. 3) through gene-enzyme analysis. At the second passage in laboratory mice, the muscle larvae were unable to survive at - 10 C for 5 days. Biological and epidemiological implications are discussed.
摘要
在意大利中部，从一只冷冻6个月的狼的咬肌中采集到了活的幼虫。通过基因酶分析，这些寄生虫被鉴定为古北区南部的一个物种（旋毛虫3型）。在实验室小鼠体内传代培养至第二代时，肌幼虫在-10℃下无法存活5天。文中讨论了其生物学和流行病学意义。
