Effects of abamectin on motility of Kirby and Wallangra adult H. contortus in vitro, alongside feeding assay dose response data (from Fig. 1). Worm motility data was analysed at different levels of sensitivity (see text for details): most sensitive (A, D), intermediate sensitivity (B, E), or least sensitive (C, F). Each data point represents mean ± SE, n = 2 separate experiments for each isolate, each with 6–12 replicate control wells, and 2–3 replicate drug-treated wells. Where SEs are not visible, they are smaller than the data point symbols.
