Rats, Rattus norvegicus, trapped in some sections (barrios) of the city of Santo Domingo, the capital of the Dominican Republic showed that 5 of them from two barrios harbored the nematode Angiostrongylus cantonensis in the pulmonary artery. Macerated and digested terrestrial snails, Subulina octona, collected from the backyards of houses where the rats were trapped contained L2 and L3 larvae of the nematode. The morphology of the adult worms and the larvae was consistent with that described for A. cantonensis in the literature. This is the first report of this Oriental and Western Pacific nematode in the Dominican Republic and the fourth in the Americas. Gastrointestinal hemorrhage, a rare symptom due to another species, the American A. costaricensis, which occurs in mesenteric arterioles of rodents and humans, is in the recent literature; the patient was a 41-year old Dominican. Thus the Dominican Republic is the first country in the Western Hemisphere to have the two species of Angiostrongylus.
在多米尼加共和国首都圣多明各的一些街区捕获的褐家鼠（Rattus norvegicus）显示，来自两个街区的5只褐家鼠肺动脉中寄生有广州管圆线虫。从捕获褐家鼠的房屋后院收集的被捣碎并消化的八齿小玛瑙螺（Subulina octona）中含有该线虫的L2和L3幼虫。成虫和幼虫的形态与文献中描述的广州管圆线虫一致。这是该东方和西太平洋线虫在多米尼加共和国的首次报告，也是在美洲的第四次报告。最近的文献报道了因另一种线虫——美洲哥斯达黎加管圆线虫（A. costaricensis）引起的胃肠道出血，这种线虫寄生于啮齿动物和人类的肠系膜小动脉，患者是一名41岁的多米尼加人。因此，多米尼加共和国是西半球第一个有两种管圆线虫的国家。
