Population structure of Haemonchus contortus from seven geographical regions in China, determined on the basis of microsatellite markers.

ABSTRACT:

Background

Studying genetic variation within and among Haemonchus contortus populations can inform some aspects of this parasite's population genetics and epidemiology. However, almost nothing is known about such variation in China.

Methods

Adult males of H. contortus (n = 184) representing seven distinct populations in China were collected, and genetic variation within and among these populations was explored using eight distinct microsatellite markers.

Results

Genetic parameters, such as heterozygosity and inbreeding coefficient (F _IS ) indicated that all eight microsatellites were highly polymorphic. Various analyses (AMOVA, F _ST , phylogenetic, structure, mantel test and population dynamics) revealed high within-population variation, low popu
