Parastrongylus (=Angiostrongylus) cantonensis, a lung worm of rats, was first reported in the United States in 1987, with a probable introduction by infected rats from ships docking in New Orleans, Louisiana, during the mid-1980s. Since then, it has been reported in nonhuman primates and a boy from New Orleans, and in a horse from Picayune, Mississippi, a distance of 87 km from New Orleans. Parastrongylus cantonensis infection is herein reported in a lemur (Varencia variegata rubra) from New Iberia, Louisiana, a distance of 222 km from New Orleans, and in a wood rat (Neotomafloridanus) and in 4 opossums (Didelphis virginiana) from Baton Rouge, Louisiana, a distance of 124 km from New Orleans. The potential of a great variety of gastropods serving as intermediate hosts in Louisiana may pose a threat to wildlife as well as to domesticated animals in the areas where infected Norway rats (Rattus norvegicus) are present.
广州管圆线虫（= 广州血管圆线虫）是大鼠的一种肺线虫，1987年首次在美国被报道，很可能是20世纪80年代中期停靠在路易斯安那州新奥尔良的船只上的感染大鼠引入的。从那时起，在非人类灵长类动物、一名来自新奥尔良的男孩以及一匹来自密西西比州皮卡尤恩（距新奥尔良87公里）的马身上都有该虫的报道。本文报道了来自路易斯安那州新伊比利亚（距新奥尔良222公里）的一只狐猴（红背白脚狐猴）、来自路易斯安那州巴吞鲁日（距新奥尔良124公里）的一只林鼠（佛罗里达林鼠）和4只负鼠（北美负鼠）感染广州管圆线虫的情况。在路易斯安那州，各种各样的腹足类动物作为中间宿主的可能性可能会对存在感染褐家鼠（褐鼠）的地区的野生动物以及家畜构成威胁。
