Four nematode species (Physaloptera clausa Rudolphi, 1819; Ph. maxillaris Molin, 1860; Protospirura numidica criceticola Quentin, Karimi and Rodrigues De Almeida, 1968; Toxascaris leonina (Von Linstow, 1902) were collected from D. griseus, D. culpaeus and C. chinga in Neuquen Province, Argentina. These hosts were captured from April to August in 1990 and 1991. Ph. clausa and Ph. maxillaris ar redescribed. The systematic position of Ph. clausa is discussed and the authors conclude that this species could be considered the type species of the genus. The possibility that D. griseus and D. culpaeus could be the accidental hosts for P. n. criceticola is discussed. Prevalence, mean intensity and frequency of each species are given. These parameters were related with the diets of the hosts and the parasite life cycles. There was no relationship between parasitic burden of each host and their nutritional condition (Kendall Tau Test). Significant differences exist among the diet of each host and among prevalence values of each parasite species (Homogeneity Test SYSTAT Program).
从阿根廷内乌肯省的灰狐（D. griseus）、草原狐（D. culpaeus）和南美狐（C. chinga）体内采集到四种线虫（克劳氏泡翼线虫（Physaloptera clausa Rudolphi，1819年）；上颌泡翼线虫（Ph. maxillaris Molin，1860年）；努米底亚原旋尾线虫环颈仓鼠亚种（Protospirura numidica criceticola Quentin、卡里米和罗德里格斯·德阿尔梅达，1968年）；狮弓蛔虫（Toxascaris leonina（冯·林斯托，1902年））。这些宿主于1990年和1991年的4月至8月间捕获。对克劳氏泡翼线虫和上颌泡翼线虫进行了重新描述。讨论了克劳氏泡翼线虫的系统地位，作者得出结论，该物种可被视为泡翼线虫属的模式种。讨论了灰狐和草原狐可能是努米底亚原旋尾线虫环颈仓鼠亚种偶然宿主的可能性。给出了每种线虫的感染率、平均感染强度和感染频率。这些参数与宿主的饮食和寄生虫的生命周期有关。每个宿主的寄生虫负荷与其营养状况之间没有关系（肯德尔陶氏检验）。每个宿主的饮食和每种寄生虫物种的感染率之间存在显著差异（SYSTAT程序的齐性检验）。
