Skin scrapings should be the most common diagnostic test performed in veterinary dermatology. A dull scalpel blade or similar instrument is moistened with mineral oil and used to scrape away some of the epidermis, in which may reside a number of different parasites. There are 2 types of skin scrapes that should be performed. A superficial skin scrape to rule out ecotoparasites of the superficia...

PURPOSE To investigate correlation between ocular Demodex infestation and serum. DESIGN A prospective study to correlate clinical findings with laboratory data. PARTICIPANTS We consecutively enrolled 59 patients: 34 men and 25 women with a mean age of 60.4+/-17.6 years (range, 17-93). METHODS Demodex counting was performed based on lash sampling. Serum immunoreactivity to two 62-kDa and 8...

Demodex is an ectoparasite living in the skin as a nonpathogen or a pathogen. It is also known that demodex acts as a vector of pathogenic microorganisms. In this study, we have investigated the rate of occurrence and vitality of demodex in forensic autopsies that have a high risk of contamination by infected organisms. The study, which was cross-sectional, conducted on 100 autopsy cases: 77 of...

Demodex was first identified over 150 years ago, but only recently has it attracted wider interest as a contributor to chronic diseases such as acne rosacea or marginal blepharitis. Demodex is commonly found in the human population, in skin sebaceous glands or follicles. The frequency of Demodex infection increases with age, as it is mainly diagnosed after the age of seventy; however, it can so...

BACKGROUND There are controversial reports about the role of Demodex mites in pathogenesis of acne rosacea. The aim of this study was to examine the relationship between the presence and number of Demodex mites and the pathogenesis of rosacea. METHODS In this case-control study, the prevalence of Demodex mites was studied in facial biopsy of 75 patients with acne rosacea as case group, and in...

Melanocytic skin tumors are caused by nevus cells, epidermal melanocytes and dermal melanocytes. The aim of the study was to detect the positivity of Demodex spp. in biopsy specimens of skin diagnosed as nevus. In this retrospective study, the specimens obtained from 110 patients diagnosed with nevus and stained by hematoxylin & eosin (H&E) method were assessed for Demodex. Statistical analysis...

BACKGROUND Demodex mites are involved in different skin diseases and are commonly detected by skin scrape tests or superficial biopsies. A new high-definition optical coherence tomography (HD-OCT) with high lateral and axial resolution in a horizontal (en-face) and vertical (slice) imaging mode might offer the possibility of noninvasive and fast in vivo examination of demodex mites. METHODS T...

Canine demodicosis is a common noncontagious parasitic dermatosis caused by different spp of Demodex mites including Demodex canis, Demodex injai and D. cornei. Generalized demodicosis can be one of the most frustrating skin diseases, one will ever treat. Conventional and newer miticidal therapies are available to veterinarian to treat this frustrating skin disease. All recognized Demodex mites...
