Objectives: To quantify (by qPCR) the density of Demodex canis mites in the skin of dogs with demodicosis and in healthy dogs, as well as measuring the serum concentrations of interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12, and tumour necrosis factor-alfa (TNF-α).
Methods: Fifty-four dogs were divided into three groups: localized demodicosis (LD, n = 16), generalized demodicosis (GD, n = 22), and control group (CG, n = 16). All dogs were subjected to skin scraping, blood collection, and skin biopsy. Read More

Australian tea tree oil (TTO) and its extract terpinen-4-ol (T4O) are found to be effective in moderating demodex-related diseases. Their possible effects are lowering the mite counts, relieving the demodex-related symptoms and modulating the immune system especially the inflammatory response. This review summarizes the topical treatments of TTO and T4O in human demodicosis, their possible mechanism of actions, side-effects and potential resistance in treating this condition. Read More

A 12-year-old female Shih-Tzu with hyperadrenocorticism and hypothyroidism developed concurrent refractory generalized demodicosis that did not respond to doramectin treatment. Although amitraz treatment was effective, the dog developed severe diabetes, which resulted in the cessation of amitraz and trilostane. Attempts to control the diabetes were unsuccessful, and its hyperadrenocorticism was left untreated, leading to the recurrence of demodicosis. Read More

Background: Papulopustular rosacea and rosacea-like demodicosis have numerous similarities, but they are generally considered as two distinct entities, mainly because the causal role of the Demodex mite in the development of rosacea is not yet widely accepted. Several clinical characteristics are traditionally considered to differentiate the two conditions; for example, papulopustular rosacea is typically characterized by central facial papulopustules and persistent erythema, whereas small superficial papulopustules and follicular scales rather suggest rosacea-like demodicosis. However, none of these characteristics is exclusive to either entity. Read More

Proposed at the beginning of the twentieth century to explain the origin of eukaryotic organelles from prokaryotes, endosymbiosis is now medically defined by various interaction patterns between microorganisms and their residing hosts, best exemplified by the bacterial endosymbiont Wolbachia identified in arthropods and filarial nematodes, which can influence normal development, reproduction, survival and transmission of the hosts. Based on the transmission modes, vertical or horizontal, and the function of the endosymbionts, the host-symbiont dependence can be divided into primary or secondary. In dermatology, the role of endosymbionts in skin ectoparasitosis has aroused great interests in the past years. Read More

There is little agreement on the most effective and safest treatment for feline demodicosis. Protocols generally consist of long-lasting therapy courses based on rinses, subcutaneous injections, oral drug administration or repeated spot-on formulation and the efficacy of most of these is poorly documented. Many of these products have also been associated with adverse effects and may be difficult to administer in cats, leading to poor owner compliance and treatment failure. Read More

Background: Demodicosis is a parasitic skin disease caused by mites, and the determination of mite density per square centimeter is important to diagnose demodicosis. Standardized skin surface biopsy (SSSB) and direct microscopic examination (DME) are commonly used to determine mites density (Dd). However, no study has previously compared these two methods with respect to clinical types and distribution patterns of demodicosis. Read More

Facial erythema (the "red face") is a straightforward clinical finding, and it is evident even to the untrained eye; however, a red face does not represent a single cutaneous entity. It may be due to a plethora of distinct underlying conditions of varying severity, including rosacea, demodicosis, dermatomyositis, lupus erythematosus, allergic contact dermatitis, drug-induced erythema, and emotional blushing. In clinical practice, dermatologists do not encounter only one type of facial erythema but rather a number of different shades of red. Read More

Numerous reports point to Demodex mites as the aetiology of certain eye and skin conditions, hence it is highly probable that infestation with these mites may also play a role in the aetiology and pathogenesis of pterygium. Therefore here we present a hypothesis: whether the presence of Demodex mites in eyelash hair follicles significantly correlates with the presence of pterygia, which could point to a potential role of these mites in the development of such lesions. We present preliminary data for supporting this hypothesis. Read More

Dermatophytoses in animals are fungal diseases of the skin caused by dermatophyte fungi of the genus Microsporum or Trichophyton. Because the infection is generally follicular, the most common clinical sign is one or many circular areas of alopecia with variable erythema, scaling and crusting, and the primary differential diagnoses are follicular infections, such as bacterial folliculitis and demodicosis. Although dermatophyte folliculitis or ringworm is the most commonly observed lesion of dermatophytoses in animals, other presentations may be observed according to the host species and the dermatophyte involved: dermatophyte folliculitis or ringworm, scaling and crusting in dermatophytosis due to Microsporum persicolor, nodule in case of kerion or mycetoma, matted hairs, seborrheic dermatosis or miliary dermatitis in cats, generalized exfoliative dermatoses in dogs, cats and horses, superficial non-follicular pustules, papules and macules in the Devon Rex cat, pruritic dermatophytoses in dogs, cats and horses, and onychomycosis in dogs, cats and horses.

Lately, the innovative concept of an immunocompromised cutaneous district (ICD) has been introduced to explain why a previously injured cutaneous site may become in time a privileged location for the onset of opportunistic infections, tumors, and immune reactions. The injuring events capable of rendering a skin region a potential ICD are various, numerous, and most of the time identifiable by means of a careful clinical history. The reason that only a small minority of injured skin areas actually becomes ICDs, with subsequent opportunistic localization of a second and unrelated skin disorder, is presently unknown. Read More
