Abstract
In Lahanam Village, Savannakhet Province, Laos, 125 of 253 villagers (49 w4%) were found by fecal examination to harbor hookworm eggs The eggs were heterogeneous in morphology and size, suggesting infections of mixed nematode species To confirm the hookworm egg species, on a voluntary basis, 46 hookworm egg-positive participants were treated with albendazole, and post-treatment adult worms were collected from purged fecal samples The common human hookworm was found in only 3 participants, 1 case of Necator americanus, and 2 cases of Ancylostoma duodenale In contrast, adult Trichostrongylus worms were expelled from most participants (43 of 46, 93 5%) The Trichostrongylus species were confirmed by morphology and internal transcribed spacer 2 sequences, all worms were of the same species (T colubriformis) In addition, some Trichostrongylus worms were obtained from a goat in the same village and identified as T colubriformis The results suggested that T colubriformis was the main zoonotic species causing hookworm infections in the village
