Prevalence of Demodex folliculorum and Demodex brevis in patients with blepharitis and chalazion.

Purpose: Demodex folliculorum and Demodex brevis are common ectoparasites on skin that also can lead to blepharitis and chalazion. The aim of our study is to determine the prevalence of Demodex spp. in eyelashes of patients diagnosed with chronic blepharitis and chalazion.

The Importance of Demodex Mites (Acari: Demodicidae) in Patients With Sickle Cell Anemia.

Although demodicosis caused by Demodex folliculorum and Demodex brevis is widely seen throughout the world, the pathogenic mechanisms are not fully known. To the best of our knowledge, the effect of Demodex mites in patients with sickle cell anemia (SCA) is not known. SCA is a genetic disease characterized by abnormal hemoglobin production and suppression of the immune system.
