Abstract
Calodium hepaticum (syn. Capillaria hepatica) is a nematode of the Capillariidae family that infects rodents and other mammals. In Brazil, human spurious infections of C. hepaticum have been detected in indigenous or rural communities from the Amazon Basin, but not in the southern states of the country. Here, we report the highest occurrence (13.5% of 37 residents) of C. hepaticum human spurious infection detected in Brazil and the first record in a southern region, Guaraqueçaba. The finding is explained by the area being located in the Atlantic Forest of the state of Paraná, surrounded by preserved forests and because the inhabitants consume the meat of wild mammals.
Highlights
The family Capillariidae of parasites (Bancroft 1893) is composed of approximately 300 worldwide-distributed species, with three occasionally infecting humans: Calodium hepaticum, Paracapillaria (Crossicapillaria) philippinensis and Eucoleus aerophilus
There are two types of infections caused by C. hepaticum: hepatic infection and spurious infection
To the best of our knowledge, there are 72 worldwide cases of human hepatic calodiasis described in the literature (Fuehrer et al 2011), five of which were reported from Brazil (Piazza et al 1963, Pereira & França 1981, Sawamura et al 1999)
Summary
The family Capillariidae of parasites (Bancroft 1893) is composed of approximately 300 worldwide-distributed species, with three occasionally infecting humans: Calodium hepaticum, Paracapillaria (Crossicapillaria) philippinensis and Eucoleus aerophilus. C. hepaticum (Bancroft, 1893), known as Capillaria hepatica, is a parasitic nematode with a cosmopolitan distribution that infects several mammals, including humans (Galvão 1981, Fuehrer et al 2011). The spurious infection occurs following the ingestion of unembryonated eggs that pass through the digestive tract and are eliminated in the faeces (Galvão 1981).
