ÖzetBu olgu sunumunda, 5 yaşlı İngiliz Pointer ırkı bir köpekte Demodex canis kökenli atipik dermatitisin teşhisi ve tedavisi değerlendirildi. Klinik, laboratuvar, bakteriyolojik, parazitolojik ve histopatolojik muayeneler ışığında, deri kazıntısı ve deri biyopsisi örneklerinden Demodex canis, β-hemolitik Staphylococcus aureus ve Microsporum canis izole ve identifiye edilen bu olgu, atipik dermatitis olarak tanımlandı. Banyo uygulaması (ketokonazol ve benzoxyl peroxide şampuan, haftada 2 kez), ivermektin (0.6 mg/kg, SC, 3 gün ara ile, 4 ay), sefaperazonsulbaktam kombinasyonu (22 mg/kg, 10 gün), cefquinom (2 mg/kg, İM, 3.5 ay) ve ketokonazol (10 mg/kg, oral, 4 ay) ile dört ay boyunca tedavi edildi. Sonuç olarak, Demodex canis kökenli atipik dermatitis olgularında tedavi süresinin uzun tutulması gerektiği ve 3 günlük aralıklarla yapılan ivermektin tedavisinin başarılı olduğu ve herhangi bir komplikasyona neden olmadığı değerlendirildi. Anahtar sözcükler: Demodex canis, β-hemolitik Staphylococcus aureus, İvermektin, Dermatitis, Köpek Successful Treatment of Atypical Dermatitis Case Caused by Demodex canis in An English Pointer SummaryIn this case, the diagnosis and treatment of atypical dermatitis caused by Demodex canis was evaluated in a-5 year old English pointer. The disease defined as atypical dermatitis due to clinical, laboratory, bacteriological, parasitological and histopatological results. Demodex canis, β-hemolytic Staphylococcus aureus and Microsporum canis were isolated and identified on the skin scrapings, biopsy specimens and swab. The dog was treated for 4 months, given bath of ketoconazole and benzoyl peroxide shampoo, twice in a week, ivermectin 0.6 mg/ kg, SC, three days interval, cefaperazone-sulbactam (22 mg/kg, IM) daily for only 10 days and followed by cefquinom (2 mg/kg IM) daily for the rest of the treatment period of 3.5 months, and ketaconazole (10 mg/kg, PO, 4 months) daily. As a result, atypical dermatitis caused by Demodex canis should be treated for longer duration with no complications and with successful outcome at 3 days interval. Demodex canis sağlıklı köpeklerin kıl foliküllerinde ve yağ bezlerinde normal olarak bulunabilen bir ektoparazittir. Etkenler doğumdan sonra kısa süre içerisinde anneden yavrulara direk kontak yoluyla bulaşır 1-3 . Etkenlerin sayısı bağışıklık sistemi tarafından kontrol altında tutulur. İmmun sistem zayıfladığında, etkenler çoğalmaya ve hastalık oluş-turmaya başlarlar 4-6 .

“…In dogs, the most commonly reported mite species is Demodex canis, which lives in hair follicles, sebaceous glands and sebaceous gland ducts. Furthermore, there is a species of Demodex injai, which also lives in hair follicles and sebaceous glands, but is more often found in adult dogs diagnosed with iatrogenic Cushing's syndrome and hypothyroidism (18,40).…”

Mites from the genus Demodex are ectoparasites of many mammals, including humans. There are over 100 Demodex species, which demonstrate strong specificity in host selection [Table 1]. The mites are common in humans. It has been estimated that up to 60% of adults may be infected, but in most cases no symptoms of the disease are present. Demodex multiplication inside sebaceous glands and hair follicles can lead to skin disease in both humans and animals. In humans, the main problem is ocular demodecosis, which can cause chronic conjunctivitis and blepharitis. In this paper, we present the biology and epidemiology of Demodex species in humans as well as in domestic and farm animals. Characteristic lesions, diagnostics and treatment of demodecosis are also described

“…The adult male D. injai measures approximately twice the length of D. canis, while the adult female is about 50% larger than the male (DESCH; HILLIER, 2003). Presumably, these mites mainly live in the glands and sebaceous ducts, and comprise the normal skin fauna of some canines (MILOSEVIC et al, 2013;SASTRE et al, 2013).…”

“…The disease is often associated with other morbidities, such as allergic dermatitis, hypothyroidism, hyperadrenocorticism, leishmaniasis, diabetes mellitus, neoplasms, and immunosuppressive treatments (MILLER et al, 2013;MUELLER et al, 2012). Clinical signs of the disease include dyskeratosis, an excessively oily coat, odor, alopecia, erythema, folliculocentric papules and pustules, hyperpigmentation, comedones, and secondary bacterial infection (DESCH; HILLIER, 2003).…”

The mite Demodex injai causes demodicosis, an uncommon, chronic, and recurrent parasitic dermatopathy in dogs. Demodicosis is characterized by an excessive proliferation of the Demodex injai mite in the pilosebaceous unit. Typically, demodicosis occurs in adults, and is associated with an underlying disease or a specific host immunodeficiency. Here, we describe the epidemiological, clinical, dermatological, and therapeutic aspects of Demodex injai demodicosis in dogs (n=8) at the Hospital Unit for Companion Animals of the Pontifical Catholic University of Paraná in Brazil. The affected dogs were predominantly purebred, had a mean age of eight years, and showed no gender predisposition. The lesions were predominantly alopecic and erythematous-desquamatory, associated with follicular dyskeratosis and greasiness of the coat, and mainly affected the facial region, in addition to the back and limbs. The animals had a history of allergic, dyskeratotic, endocrine, neoplastic, and immunosuppressive comorbidities. The diagnosis of demodicosis was based on multiple skin scrapings, trichogram, and acetate tape impression of the lesion areas, macroscopic observation, and morphological characterization of the mite. Macrocyclic lactones were effectively used for treatment in most cases; however, improvement of the condition may be related to adjunctive treatment of the underlying disease. Key words: Canine. Clinical signs. Demodectic mange. Dermatopathy. Mites. ResumoDemodiciose provocada pelo ácaro Demodex injai é uma dermatopatia parasitária, crônica, recorrente, incomum em cães, caracterizada pela proliferação excessiva do ácaro na unidade pilossebácea. É frequentemente caracterizada como de surto adulto, generalizada e associada a uma doença de base ou a uma imunodeficiência específica inerente ao hospedeiro. O presente relato tem como objetivo descrever os aspectos epidemiológicos, clínico-dermatológicos e o tratamento da demodiciose por Demodex injai em cães (n=8) atendidos na Unidade Hospitalar para Animais de Companhia da Pontifícia Universidade Católica do Paraná, em São José dos Pinhais, Paraná, Brasil. Os animais acometidos apresentaram idade média de oito anos, predominantemente de raças puras e não houve predisposição sexual. As lesões tinham características predominantemente alopécicas e eritêmato-descamativas, associadas à disqueratose folicular e untuosidade da pelagem, acometendo principalmente a região da face, mas também o dorso e os membros. Os animais apresentavam histórico de comorbidades alérgicas, disqueratóticas, endócrinas, neoplásicas ou imunossupressivas de base. O diagnóstico da demodiciose foi estabelecido por múltiplos raspados de pele, tricograma e técnica de beliscamento por fita adesiva em áreas lesionais, seguindo à observação macroscópica e caracterização morfológica do ácaro. Instituiu-se tratamento com lactonas macrocíclicas, que se mostraram eficazes na maioria dos casos, entretanto, a involução do quadro pode estar relacionado ao tratamento adjunto das doenças de base.
