mites live in the skin of dogs in small numbers, often kept at bay by the dog's immune system.
The cause of rosacea remains unclear and differs within subgroups, but previous studies have suggested an association between rosacea and the presence of Demodex
mites, wrote Yin-Shuo Chang, MD, and YuChen Huang, MD, of Taipei (Tawiwan) Medical University (J Am Acad Dermatol.
Moreover, there is an article on the relationship between acute appendicitis and enterobiasis and two articles discussing the existence of Demodex
and its symptoms.
Hence, according to the researchers, there is a need for advancements in the identification methods of Demodex
mites in order to achieve effective treatment of these skin afflictions.
While rosacea is an inflammatory disorder, not an infection, drugs like ivermectin and crotamiton 10% cream (Eurax) that kill Demodex
also improve rosacea, he observed.
However, if Demodex
is causing the itching, systemic miticidal agents will be needed for months on end," Dr.
The most important point for patients to understand is the main triggers of their rosacea, which can include ultraviolet light, spices, stress, exercise, heat, barrier disruption, and Demodex
Researchers identified four lineages of microscopic Demodex
folliculorum mites living on the foreheads, cheeks and noses of 70 volunteers.
Though the etiology of rosacea is not fully understood, immune system dysfunction, inflammatory reaction to cutaneous microorganisms, Demodex
folliculorum infestation, environmental factors like sunlight, and vascular anomalies have been implicated in its pathogenesis.
In dog, demodex
mites are acquired by neonates from bitch and mites are considered a normal resident of skin in few numbers.
Su implicacion en sanidad animal esta dada por la incomodidad generada en el hospedero debida a la irritacion, prurito y a las lesiones ocasionadas por la penetracion subcutanea de los acaros ante la creacion de tuneles en el estrato corneo de la piel, o como en el caso de Demodex
gatoi por su localizacion en el estrato corneo.
The role of Demodex
folliculorum, commensal mite of the pilosebaceous follicle, has long been debated; it would promote inflammation by mechanical blockage of follicles.
