The ''Ornithonyssus'' mite is closely related to the [[Dermanyssus gallinae|''Dermanyssus'']] mite. They are [[Non-Burrowing Mites|surface mites]] that occur in caged birds and poultry.

==Identification==

*Occurs in caged birds and poultry
  
The mites are small and very motile. They have a few hairs present and are semi-transparent in colour until they have a blood meal. They are oval in shape and have eight legs, except the larvae which have 6 legs.

==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.
