PURPOSE To determine the prevalence of Demodex in eyelashes with cylindrical dandruff (CD). METHODS A modified sampling and counting method was applied to 55 clinical cases. Patients were divided in to group A (n = 20) with diffuse CD, group B (n = 12) with sporadic CD, and group C (n = 23) with clean lashes or greasy scales, of which the latter was divided into subgroup C1 (n = 15) without l...

DEMODEX – THE MITES In the dog, the most common species of Demodex is Demodex canis. More recently, Demodex injai and the short tailed demodex, Demodex cornei have been identified. Demodex canis is a “cigar-bodied” mite measuring170-225 microns, and is transferred from the bitch to the suckling puppy within the first 3 days of life. It is considered a commensal organism of dogs and only becomes...

Demodex mites, although usually nonpathogenic, can cause a wide range of dermatological lesions ranging from mild skin irritation and alopecia to severe furunculosis. Recently, a case of demodicosis from a white-tailed deer (Odocoileus virginianus) revealed a Demodex species morphologically distinct from Demodex odocoilei. All life cycle stages were considerably larger than D. odocoilei and alt...

BACKGROUND Demodex is a genus of mites living predominantly in mammalian pilosebaceous units. They are commonly detected in the skin of face, with increasing numbers in inflammatory lesions. Causation between Demodex mites and inflammatory diseases, such as rosacea, blepharitis, perioral and seborrhoeic dermatitis or chalazion, is controversially discussed. Clinical observations indicate a prim...

Demodex spp. was investigated in the 258 university students that participated in the study aimed to investigate Demodex spp. prevalence among university students in Elazig with the methods of cellophane band and standard superficial skin biopsy (SSSB). Of the students, 26 (10.07%) were established as Demodex spp. positive. Demodex spp. prevalence was observed as high among advanced age groups;...

BACKGROUND Molecular characterization of Demodex mites is being used to identify mite species in dogs. This technique is now being applied to cat Demodex species, allowing for better characterization of the mites. HYPOTHESIS/OBJECTIVES Molecular diagnostics will clarify the existence of diverse Demodex mites identified morphologically. ANIMALS A cat with generalized demodicosis secondary to...

the ability of smartphone technology to document static microscopy images has been well documented and is gaining widespread use in ophthalmology, where slit-lamp biomicroscopy is frequently utilized. however, little has been described regarding the use of smartphone technology to relay video of tissue microscopy results to patients, particularly when a tissue sample integrates motility of orga...

Demodex mites are a group of hair follicle and sebaceous gland-dwelling species. The species of these mites found on humans are arguably the animals with which we have the most intimate interactions. Yet, their prevalence and diversity have been poorly explored. Here we use a new molecular method to assess the occurrence of Demodex mites on humans. In addition, we use the 18S rRNA gene (18S rDN...
