Rosacea is a common dermatological condition that predominantly affects the central regions of the face. Rosacea affects up to 3 % of the world's population and a number of subtypes are recognized. Rosacea can be treated with a variety of antibiotics (e.g. tetracycline or metronidazole) yet no role for bacteria or microbes in its aetiology has been conclusively established. The density of Demod...

Folliculitis is a common complaint and its etiology may be related to a variety of factors. We examine a case involving a 57-year-old white man presenting with scalp erythema and folliculitis secondary to Demodex mite infestation. We discuss the pathophysiology of Demodex folliculitis, as well as the epidemiology, clinical manifestation, diagnosis, and treatment of this infection.

Two species of demodectic mites were described in the red deer Cervus elaphus, including Demodex kutzeri, which had also been found in other species of the Cervidae family in Austria, Germany, Czech Republic, Poland and North America. Whereas the other species, D. acutipes, had been previously known from only one finding in the Czech Republic. The present research included skin samples taken in...

Demodex spp may cause blepharitis and palpebra skin lesions. Since eyelash demodicosis seems to be quite spreadable in the community, every patient with chronic non-diagnosed blepharitis should be examined for Demodex spp. Tea tree oil treatment may be an efficient and safe therapeutical choice against ocular demodicosis.

The nature of association between Demodex mites and bacteria involved in bovine demodectic mange lesions and the normal flora inhabiting the skin of noninfected animals was investigated. Demodex bovis and D. ghanensis mites were isolated from the infected purulent material extracted from skin and meibomian gland lesions, respectively. The mites could not be demonstrated in skin brushings or imp...

Parasites collected from free-ranging black bears, Ursus americanus, in northern Wisconsin included Dermacentor variabilis, D. albipictus, Ixodes scapularis, Demodex sp., Trichodectes pinguis euarctidos, Baylisascaris transfuga and Dirofilaria ursi. Mange, possibly caused by the Demodex sp., also was observed. Dental caries were common and periodontal disease was observed in one animal.

We report the case of a 56-year-old HIV-seropositive man who presented a facial Demodex infection developed 2 months after initiation of highly active antiretroviral therapy. The Demodex infection was confirmed by scrapings and histopathologic examination and by the dramatic response to antiparasitic treatment with oral ivermectin associated with 5% permethrin cream.

Demodicidosis may present as pityriasis folliculitis, papulopustular lesions, rosacea-like eruptions, and granulomatous rosacea-like eruptions. The diagnosis of demodicidosis made by finding extrafollicular mites in the perifollicular inflammatory infiltrate. The papules resolved after 3 weeks of systemic and topical metronidazole, and low-dose oral prednisolone therapy. In summary, demodex gra...
