Dermanyssus gallinae (chicken mite): an underdiagnosed environmental infestation.
Summary of "Dermanyssus gallinae (chicken mite): an underdiagnosed environmental infestation."
Dermanyssus gallinae is a mite that normally parasitizes small birds but may occasionally bite humans. We report an unusual case of an 82-year-old woman who presented with pruritus and bite-like lesions over her trunk. Other members of the household were also affected. On physical examination, mites < 1 mm in size were found on the patient's body. The family were residing in the city centre and had no pets, but there were pigeon nests in close proximity to the house. Most dermatologists have difficulties identifying ectoparasitosis. In the case of D. gallinae, the small size of the mites and the fact that they leave the host after feeding means that they may not be seen at presentation, thus such infestations are likely to be underdiagnosed. Physicians should be aware that infection with this mite is possible even in patients from urban areas, and it should be included in the differential diagnosis of conditions causing recurrent pruritus unresponsive to standard treatments.

Medical and Biotech [MESH] Definitions
Infestation of animals with parasitic worms of the helminth class. The infestation may be experimental or veterinary.
An infection caused by the infestation of the larval form of tapeworms of the genus Echinococcus. The liver, lungs, and kidney are the most common areas of infestation.
Species of European house dust mite, in the family PYROGLYPHIDAE. It is the most commonly found house dust mite.
Antigens from the house dust mites (DERMATOPHAGOIDES), mainly D. farinae and D. pteronyssinus. They are proteins, found in mite feces or mite extracts, that can cause ASTHMA and other allergic diseases such as perennial rhinitis (RHINITIS, ALLERGIC, PERENNIAL) and atopic dermatitis (DERMATITIS, ATOPIC). More than 11 groups of Dermatophagoides ALLERGENS have been defined. Group I allergens, such as Der f I and Der p I from the above two species, are among the strongest mite immunogens in humans.
Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.
