[An unusual roundworm (Toxocara vitulorum) infection in suckling calves].

A 2-month-old suckling calf had complaints of diarrhea and roundworms near the perineum. Faecal examination showed the presence of a high number of roundworm eggs of Toxocara vitulorum. The calf was a daughter of a Piemontese cow, born on the farm, but with a grandmother imported from France. This case describes the measures taken on the farm to prevent clinical problems and dissemination of the infection to other farms.
