New morphological details and first records of Heterakis spumosa and Syphacia muris from Argentina
Heterakis spumosa and Syphacia muris are among the most common species parasitizing mammals. Although these nematodes have been reported from many hosts on several continents, in South America, they have only been recovered from the cecum of Rattus norvegicus from Brazil and Peru. This study provide...

Heterakis spumosa and Syphacia muris are among the most common species parasitizing mammals.

This study provides morphological details of H. spumosa and S. muris. Moreover, this is the first record of these species in Argentina. Heterakis spumosa and S. muris were collected from specimens of R. norvegicus from Partido de Exaltación de la Cruz, Buenos Aires Province, Argentina.
