Also known as: The Northern mite or Northern feather mite

The Ornithonyssus mite is closely related to the Dermanyssus mite. They are surface mites that occur in caged birds and poultry.

Life cycle

The mite spends its entire life cycle on the host.

Pathogenesis

The mite causes feathers to become matted and severe scabbing can develop. Scabs are particularly seen around the vent. The presence of the mite decreases egg production. Grey or black discolouration of feathers is seen when large numbers of mites are present.
