The hookworm eggs were morphologically heterogeneous, so that identification was confirmed by copro-PCR with specific primers for hookworms and Trichostrongylus spp.; 12 samples were positive for Necator americanus, 19 for Ancylostoma spp., with one mixed infection of both. Sequencing of the Ancylostoma spp. copro-PCR products found A. duodenale, and also the animal hookworms, A. caninum and A. ceylanicum. Moreover, Trichostrongylus spp.-specific copro-PCR revealed a significant rate of infection (43/203; 21.2%). Sequencing confirmed the zoonotic species, T. colubriformis. PCR/sequencing is useful for differentiating parasite species. The positives by the Kato-Katz method, and by the combined hookworm/. Trichostrongylus specific-PCR, were comparable, although the agreement between the two methodologies was only 50%. © 2010 Royal Society of Tropical Medicine and Hygiene.Mahidol UniversityImmunology and MicrobiologyMedicineArticleSCOPUS10.1016/j.trstmh.2010.06.006
