Confirming the prevalence of zoonotic canine hookworm Ancylostoma ceylanicum in the North Viet Nam based on morphology and mitochondrial gene analysis

Abstract

Survey on canine hookworms from dog in Ha Noi, Viet Nam has obtained two different hookwormspecies basing on a number of tooth in their oral cavity. The result of CO1 mitochondrial gene segment analyses of the hookworm strains confirmed that the hookworms having 3 teeth belonged to Ancylostoma caninum species and the hookworms having 2 teeth belonged to Ancylostomaceylanicum species. This is the first molecular analysis study to confirm the canine hookworm species that can transmit to human in the North Viet Nam, warning the risk of hookwormtransmission in the community. In addition, genetic diversity and phylogenetic relationshipof Ancylostoma species were also discussed in this study.
