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 unresponsiveness) in the food storage of a goat
production facility. The liver was observed with hepatomegaly and diffuse and irregular yellowish-white spots
appearing in striae or small nodules on the external surface and inside the liver. Subsequent microscopic and
histopathological studies were performed. Eggs were observed by direct microscopy of the impression smear of
liver tissue. A multifocal granulomatous tissue reaction with different stages of fibrocellular tissue was observed
in the liver parenchyma. The granulomas contained adults and degenerated eggs delimited by an intense infiltrate
of mononuclear cells. Macro and microscopic observations and histopathological liver lesions were
compatible with C. hepaticum infection. To our knowledge, this is the first confirmation of C. hepaticum infection
in R. rattus in Argentina, increasing the host record of this parasite and a new record of distribution in goat
production systems in the country.
