trombiculidiasis

trombiculidiasis

dermatitis in all pastoral animal species and birds caused by mites of the family Trombiculidae. The bites produce wheals and intense pruritus followed by the development of moderate to severe dermatitis. This is mostly on the lower part of the face and the distal extremities. The disease is most likely to occur in autumn when the parasites are active and is often confined to particular fields that provide the best ecological niche for the mite.
