title: Skin nodules in East Coast fever.
abstract: A skin eruption developed in five calves with advanced experimental East Coast fever (ECF) (Theileria parva infection). In three cases the eruption was due to intradermal nodules containing numerous theilerial schizonts, in one animal the nodules contained abscesses filled with Demodex mites, and in the fifth calf both types of nodules were present. No nodules were seen in 15 other experimental cases of ECF, which generally died or were killed in an earlier stage of the disease. It is postulated that demodicosis may become apparent in healthy carriers of the mite in the course of ECF, because of immuno-depression caused by the latter disease.
