| absence of population genetic structure in heterakis gallinarum of chicken from sichuan, inferred from mitochondrial cytochrome c oxidase subunit i gene. | population genetics information provides a foundation for understanding the transmission and epidemiology of parasite and, therefore, may be used to assist in the control of parasitosis. however, limited available sequence information in heterakis gallinarum has greatly impeded the study in this area. in this study, we first investigated the genetic variability and genetic structure of h. gallinarum. the 1325 bp fragments of the mitochondrial cox1 gene were amplified in 56 isolates of h. gallina ... | 2016 | 26394200 |
