Description
Summary:The bovine hookworm Bunostomum phlebotomum (Nematoda: Bunostominae) is a blood-feeding nematode with important socioeconomic impact in the cattle breeding industry. In the present study, the complete mitochondrial genome sequence of a representative individual of B. phlebotomum from beef cattle in Southwest China was determined using the next generation sequencing technology. The genome was 13,799 bp in size and encoded 12 protein-coding genes, 22 tRNA genes and two rRNA genes. The phylogeny revealed that although B. phlebotomum from Chinese beef cattle and yaks were more closely related to each other than to that from Australian cows, these three bovine-originated B. phlebotomum grouped together and formed paraphyletic relationships with Bunostomum trigonocephalum (goat/sheep hookworm) and Necator americanus (human hookworm), supporting their sister-species relationships within Bunostominae. The cumulative mitochondrial DNA data provides a better understanding of phylogenetic relationships of this species in cattle.
