Mean frequencies (%) ± standard deviation (SD) of benzimidazole resistance associated alleles in isotype 1 β-tubulin gene of Haemonchus contortus isolates from South Darfur, Sudan, measured by pyrosequencing

Isolate	Codon 167 (TAC)	Codon 198 (GCA)	Codon 200 (TAC)
Kass	3.3 ± 0.5	Failed	6.8 ± 1.0
Nyala	4.5 ± 1.3	Failed	10.8 ± 4.0
Tulus	3.3 ± 0.5	Failed	6.0 ± 2.0
Um Dafuq	3.3 ± 1.5	Failed	6.5 ± 2.4
Total	3.6 ± 1.1	Failed	7.4 ± 3.1

Notes: The samples were pooled adult male H. contortus (11–84 worms/each sample) from goats after treatment with 5 or 10 mg/kg body weight albendazole. For each area, two biological and two technical replicates were analysed
