Presentation
Entire Body System
- Asymptomatic
Because demodicosis is highly age-dependent and can be found in asymptomatic adults, the pathogenicity of these mites has long been debated. [ncbi.nlm.nih.gov]
These infestations are actually usually asymptomatic, which means you won't feel anything or see anything as a result of it. [study.com]
- Recurrent Inflammation
During a follow-up period of 8.3 4.6 months, 1 patient showed recurrent inflammation, which was successfully managed by a second round of TTO treatment. [ncbi.nlm.nih.gov]
Skin
- Partial Alopecia
Crusty skin lesions and flaking scales ( J15 .21.w1, B284 .6.w6, B291 .12.w12) BEARS In a female Ursus americanus - American black bear from northern Wisconsin, partial alopecia and scabs. ( J1 .14.w9) Five of 70 live-trapped bears were noted to have [wildpro.twycrosszoo.org]
- Skin Thickening
Symptomatic forms are seen most commonly in the dog and include: Localised lesions: slight hair loss and skin thickening on the face and forelimbs. [wildpro.twycrosszoo.org]
Eyes
- Strabismus

Psychiatrical
- Suggestibility
A review of three previous reports suggested that one mite for every two lashes represents an over population of this nearly ubiquitous mite. Greasy scales on the lashes and foamy tears suggested that seborrhea was present as well as demodicosis. [ncbi.nlm.nih.gov]
- Fear
Evidence of phobia should, provisionally, be labelled with the nonperjorative term symbiophobia (herein coined for "fear of association with organisms"), and the causative organisms, if present, treated. [ncbi.nlm.nih.gov]
Neurologic
- Confusion
While human demodicosis is a skin disease sui generis, it can mimic many other inflammatory dermatoses, such as folliculitis, rosacea and perioral dermatitis, leading to unspecific and confusing descriptions in the literature. [ncbi.nlm.nih.gov]
Workup
HLA Type
- HLA-A2
Individuals who have the HLA A2 phenotype are 2.9 times more resistant to demodicosis. A positive correlation between demodicosis and the haplotypes A3-Cw4, A3-Cw2, A3-B17, A3-B35 and B35-Cw4 was found. [ncbi.nlm.nih.gov]
