Abstract

Two human cases of infection with Lagochilascaris are described from Colombia. One patient was a 21 year-old woman who suffered from repeated attacks of tonsillitis and passage of worms from the nose. When a tonsillectomy was performed, numerous worms were found in the tissues. Treatment with thiabendazole and mebendazole was ineffective. She was cured after treatment with levamisole. The second patient was a 7 year-old girl who had a painful abscess on the neck that contained adult worms. She was also cured of this infection after treatment with levamisole. These are the first cases described from Colombia, and bring the total number of human cases recorded to twenty-three.
