Mammomonogamus (Syngamus) laryngeus infection: a first case report in Thailand.

Abstract

The first case of M. laryngeus infection identified in Thailand is presented. The infection occurred in a 32-year-old farmer from Khon Kaen Province, who had spent 4 months in the rainforest of Kalantan State, Malaysia, as a woodcutter from May 1991 to August 1991. About 2 months after arrival in Malaysia, he developed illness with cough, thick mucoid sputum, pyrexia, malaise, pulmonary haemoptysis and weight loss. On examination in Thailand weight loss was apparent, with Strongyloides stercoralis larvae, and ova of Opisthorchis viverrini, Taenia species, echinostome species, hookworms, Trichuris trichiura and M. laryngeus present in his stools. Examination of sputum specimens expectorated after a severe bout of coughing showed many copulating worms of characteristic shape. 96 worms were observed between 11 and 14 September 1991. The worms were microscopically identified as M. laryngeus. The man recovered completely after treatment with mebendazole (200 mg/day) for 10 consecutive days and was discharged 12 days after hospitalization.
