Zoonotic nematode in the city of La Plata, Argentina: Report of a case of Calodium hepaticum in Rattus rattus
This study describes a case of Calodium hepaticum (Trichinellida: Capillariidae) infection in an adult rat (Rattus rattus) from the periurban area of the city of La Plata in the province of Buenos Aires, Argentina. The rat was found with neurological signs (ataxia, lethargy, and episodes of unrespon...
