The reported incidence of the metastrongylid nematode Angiostrongylus vasorum, that infects dogs and other canids, is increasing worldwide outside recognized endemic foci. This apparent expansion of the parasite's range is causing concern to veterinary clinicians as the disease caused in dogs can be life threatening and its treatment is not straightforward. The red fox is thought to be a reservoir host for dogs. To investigate the spatial distribution of infection in foxes in Ireland, the hearts and lungs of 542 foxes from all over Ireland were examined. The incidence of infection was found to be 39·9% [95% confidence interval (CI) 35·7-44·1] with positive samples occurring in each of the country's 26 counties. This report confirms that the parasite is endemic in Ireland and the overall prevalence is the second highest in Europe. This is the first survey of A. vasorum infection in Irish foxes and highlights the potential exposure of the Irish dog population to high risk of cross-infection. Additionally, Crenosoma vulpis was found in seven of the foxes, a parasite not previously reported in the Irish fox.
据报道，感染犬类及其他犬科动物的管圆线虫属线虫——血管圆线虫（Angiostrongylus vasorum）在全球公认的地方性疫源地以外的地区发病率正在上升。这种寄生虫分布范围的明显扩大引起了兽医临床医生的关注，因为犬类感染该疾病可能会危及生命，而且治疗并不简单。赤狐被认为是犬类的储存宿主。为了调查爱尔兰狐狸感染的空间分布情况，对来自爱尔兰各地的542只狐狸的心脏和肺进行了检查。结果发现感染率为39.9%[95%置信区间（CI）35.7 - 44.1]，该国26个县均有阳性样本出现。本报告证实该寄生虫在爱尔兰为地方性流行，总体患病率在欧洲排名第二。这是爱尔兰狐狸血管圆线虫感染的首次调查，凸显了爱尔兰犬类种群面临交叉感染高风险的潜在可能性。此外，在7只狐狸中发现了狐肺刺线虫（Crenosoma vulpis），这是一种此前未在爱尔兰狐狸中报道过的寄生虫。
