Allopsoroptoides galli

Allopsoroptoides galli is a species of feather mite which belongs to a group of mites classified in the Pandalurinae (Psoroptoididae). A. galli can be transmitted by wild birds to pet poultry. Major outbreaks have occurred in commercial egg-laying hens in Brazil. Clinical signs of infestation with A. galli include areas of intense itching, feather loss and skin lesions. Close examination of the skin reveals generalized scaly dermatitis with mucus-like material and yellowish crusts and around the calami. Mites may be seen with a magnifying glass.
