From: Microsatellite marker analysis of Haemonchus contortus populations from Pakistan suggests that frequent benzimidazole drug treatment does not result in a reduction of overall genetic diversity

Relative frequencies of the F200Y (TAC), F167Y (TAC) and E198A (GCA) isotype-1 β-tubulin benzimidazole resistance mutations in H. contortus populations from the Punjab region of Pakistan. Each H. contortus population is represented by three pie charts; one for each resistance mutation; F200Y (TTC/TAC), F167Y (TTC/TAC) and E198A (GAA/GCA). Each of these pie charts shows the relative frequency of the resistant versus susceptible SNP, based on allele quantification by pyrosequence genotyping of pooled DNA from between 14–32 worms per population (Additional file 1: Table S1). The resistance-associated SNP genotype frequency - F200Y (TAC) - is shown in white and the “susceptible” SNP genotype frequencies - F200Y (TTC), F167Y (TTC) and E198A (GAA) - are shown in black. Geographic locations of abattoirs are indicated with small circles on the map and the abattoir names from which the samples were obtained are shown above the labelling lines. The province is indicated on the map (A) Punjab
