Ornithonyssus sylviarum är en blodsugande yttre parasit (kvalster) som orsakar hudinflammation och smutsig fjäderdräkt i kloakregionen hos fjäderfän. Sänkt äggproduktion och blodbrist kan förekomma.
It frequently bites humans and produces large, irritating, papular lesions. Most species feed nocturnally and all those that affect humans tend to produce a similar response consisting firstly of itching, the onset of which may be delayed by some hours, followed by a rash.
There are two main species of bird mites commonly found in North America. These are Demanyssus Gallinae (D. Gallinae) and Ornithonyssus Sylviarum (northern fowl mite or NFM). There are also other bird mite species found mainly in other regions of the world that are very similar, such as Ornithonyssus Bursa (tropical fowl mite). Most researchers contend that there could very well be other parasitic bird mite species still unclassified. The northern fowl mite, Ornithonyssus sylviarum, is regarded as the primary and most serious ectoparasite of poultry in North America (Axtell and Arends, 1990). Mites and lice are the most destructive external parasites of poultry flocks (Goddard and Edwards, 2010).
Ornithonyssus benoiti Till, 1982 The Northern Fowl Mite (NFM) (Ornithonyssus sylviarum) is a relatively common ectoparasite of chickens. They are very small mites, ranging in size from 0.6-1 mm (0.02-0.04 in). NFM permanently live their entire lives on their host, spending most of their time on the feathers, traveling to the skin surface to feed on blood. During heavy infestations, NFM can cause the chickens a great deal of Northern fowl mite (Ornithonyssus sylviarum) control evaluations using liquid formulations of diatomaceous earth, kaolin, sulfur, azadirachtin, and Beauveria bassiana on caged laying hens.

Chronic pruritus: an uncommon cause. Avian mite dermatitis caused by Ornithonyssus sylviarum (Northern fowl mite). fowl mite (Ornithonyssus bursa), northern fowl mite (Ornithonyssus sylviarum), and chicken mite (Derma-nyssus gallinae), associated with domestic or wild birds, can also be found in homes. Although none of these species are truly parasitic on humans or pets, they will readily bite humans.
Bird mites (aka chicken mites) usually live off of birds, but can attack humans. Discover more facts about mite control.
Due to the difficult Ornithonyssus: ( ōr-ni-thon'i-sŭs ), A genus of bird and rodent mites; species include Ornithonyssus bacoti , the tropical rat mite, a possible vector of murine typhus and a cause of human dermatitis; Ornithonyssus bursa , the tropical fowl mite; and Ornithonyssus sylviarum , the northern fowl mite. [G. ornis ( ornith- ), bird, + nyssus, to prick] Although Ornithonyssus bursa is the most common mite associated with infestation of homes there are several other mites associated with birds within Australia that can invade dwellings and bite humans. These bird mites include Ornithonyssus sylviarum (Northern fowl mite) and Dermanyssus gallinae (Chicken mite). The poultry mites, Dermanyssus gallinae (Poultry Red Mite—PRM), Ornithonysus sylviarum (Northern Fowl Mite—NFM), and Ornithonyssus bursa (Tropical Fowl Mite—TFM) are endemic species across the Asian continent. In less frequency, scaly leg mite, depluming mite, and fowl cyst mite were documented.
The northern fowl mite (Ornithonyssus sylviarum) and chicken mite (Dermanyssus gallinae) primarily infest chickens, but also pigeons, starlings and sparrows. The northern fowl mite cannot survive for more than a month off its host, while the chicken mite hides in cracks and crevices near bird nests during the day and feeds by night. The northern fowl mite, Ornithonyssus sylviarum (Canestrini & Fanzago, 1877), is found on several continents and has been a major pest of poultry in the United States for nearly a century. Lack of earlier USA reports in the United States suggests an introduction or change to pest status in domestic poultry systems occurred in the early 1900s. Attacks cause people discomfort similar to that caused by Ornithonyssus sylviarum, northern fowl mite, which is also a pest of domestic fowl and wild birds. Other than bandicoots and gerbils it apparently does not attack other mammals except humans and this occurs only when a bird or fowl host is not available. Dermanyssusgallinae (chicken mite) and Ornithonyssus sylviarum (northern fowl mite) are collectively referred to as bird mites.

Ornithonyssus sylviarum has been recorded in nests of various birds in several European countries (Ambros et al., 1992; Kri˘stofík et al., 2007) which are reared or kept by humans. In order to get an overview of the different bird ecologies, samples have been collected in a diver-

When these mites are unable to take blood meals from birds, they search out alternative hosts; in humans, this often leads to the development of pruritic dermatitis. The northern fowl mite (Ornithonyssus sylviarum) and chicken mite (Dermanyssus gallinae) primarily infest chickens, but also pigeons, starlings and sparrows. The northern fowl mite cannot survive for more than a month off its host, while the chicken mite hides in cracks and crevices near bird nests during the day and feeds by night. This could benefit producers, animal welfare advocates, and human health by reducing 1) costs of beak trimming, 2) pesticide treatment costs (including human and bird chemical exposure concerns), and 3) objections to beak trimming from the animal welfare community.
