Abstract

, a parasite transmitted by squirrels, is beginning to spread in Europe. was detected in a symptomatic human. A 44-year-old man from the Czech Republic suffered from gastroenteritis characterized by abdominal pain, nausea, and loose stools. Molecular analyses confirmed the XIVaA20G2T1 subtype in the patient's stool. At the same time, the same subtype of was detected in three red squirrels and two ground squirrels in the area where the patient lived. The intensity of the infection was significantly higher in the red squirrels that died, while the ground squirrels showed no symptoms. The results of the study indicate that red squirrels and ground squirrels are the reservoirs for the infection.

摘要

一种由松鼠传播的寄生虫开始在欧洲蔓延。在一名有症状的人类身上检测到了该寄生虫。一名来自捷克共和国的44岁男子患有肠胃炎，症状为腹痛、恶心和腹泻。分子分析证实患者粪便中存在XIVaA20G2T1亚型。与此同时，在患者居住地区的三只红松鼠和两只地松鼠身上也检测到了相同亚型的该寄生虫。死亡的红松鼠感染强度明显更高，而地松鼠没有症状。研究结果表明，红松鼠和地松鼠是这种感染的宿主。
