Tick weight and percent infested sheep. (A) Replete female ticks collected from vaccinated and control sheep were weighed, the weight (mg) represented as Ave ± SD and compared between sheep in the vaccinated farm before and after vaccination and between vaccinated and control sheep by Student’s t-test with unequal variance (*p < 0.05). (B) Percent infested sheep in vaccinated and control farms. The time of immunization shots are indicated with arrows. (C) Percent infested sheep before and after vaccination with SUB-MSP1a was represented as Ave ± SD and compared between vaccinated and control sheep by Student’s t-test with unequal variance (*p < 0.05). (D) Range values for the percent infested sheep in vaccinated and control farms before and after vaccination. Average values are shown to illustrate differences between vaccinated and control animals.
