The rate of spread of sheep scab within small groups of Merino and Dorper sheep.

Journal of the South African Veterinary Association, 2003
A single Merino sheep, artificially infested with the sheep scab mite, Psoroptes ovis, and a similarly infested Dorper sheep were placed with 9 uninfested Merino or 9 uninfested Dorper sheep respectively during winter and the rate of spread of infestation on the uninfested sheep observed. The same procedure was repeated in summer.
