SummaryThe prevalence of hookworm eggs in fecal samples, by modified cellophane thick-smear technique, was found to be 30.0% (61/203 samples) in Lahanam Village, Savannakhet Province, Lao PDR. 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%.
