 en Larval recovery of Toxocara cati check for this species in other resources in experimentally infected Rattus norvegicus check for this species in other resources and analysis of the rat as potential reservoir for this ascarid

Abstract

Toxocara cati check for this species in other resources is a common feline parasite transmitted by the ingestion of embryonated eggs, by the transmammary route or by predation of paratenic hosts harbouring third-stage larvae in their bodies. In the present study, the larval distribution of T. cati in tissues and organs of Rattus norvegicus check for this species in other resources experimentally infected with 300 embryonated eggs was analysed. Third-stage larvae were recovered from livers, lungs, kidneys, eyes, brains and carcasses of infected rats, following tissue digestion with HCl 0.5% for 24 h at 37°C. Some differences from the known larval distribution of Toxocara canis check for this species in other resources in the same rodent species were found.
