“…Bowden et al [44] found that dogs of the American pit bull and West Highland White Terrier breeds and those with allergic diseases were more predisposed to demodicosis. Likewise, Gasparetto et al [8] verified that dogs with a defined breed were the most affected.…”

“…Dogs with adult onset (over 48 months) of demodicosis were also more likely classified as generalised, with 87.1% of the cases [44]. In Brazil, a study involving 46 dogs, 24 males and 22 females showed generalised demodicosis (60.9%) was more common than localised (39.1%) with a mean age of onset of 23 months [8].…”

“…Unlike the localised disease, the generalised form of demodicosis can reach serious proportions and clinical signs such as alopecia, desquamation and erythema (Figure 2) are particularly intense [8]. Secondary bacterial infection is often due to the proliferation of opportunistic microorganisms, mainly Staphylococcus pseudintermedius and Pseudomonas [47,48], which progress from superficial folliculitis to severe cases of furunculosis and cellulitis [7,10,49].…”

Gasparetto et al [8] observed pyoderma in 95.5% of dogs with generalised demodicosis and half presented with pruritus, indicating bacterial pyoderma and an immunological reaction against Demodex [9,50]. In more severe cases, lymphadenopathy, fever, anorexia and lethargy associated with secondary bacterial infection may occur [51,52].…”

“…Peri-folliculitis, mural folliculitis and furunculosis are histopathological findings observed, with demodicosis in both clinical forms of the disease due to the action of the mite inside the hair follicles [8]. However, the severity of the lesions may vary depending on the presence and extent of secondary bacterial infection, characterised by pyoderma [9,10].…”

Canine demodicosis is a common and often severe dermatopathy of dogs. It is caused mainly by Demodex canis, a parasitic mite of the skin of dogs of the genus Demodex, of the order Acarina and family Demodecidae. This study is aimed to review the clinical-pathological presentation of canine demodicosis and the cytokine-mediated immune response to the cutaneous density of the mite. Only dogs with a defective immune response will present the disease, whether localised or generalised. Microscopically, the dermal inflammatory response is similar among dogs. Localised and generalised demodicosis and pyoderma associated with a high cutaneous density of mites are factors associated with aggravation of lesions in both forms of disease presentation. In addition, the participation of cytokines has been investigated in the induction of the immune response in the different forms of the disease. Although different research groups have invested in studies aimed at elucidating the canine demodicosis pathogenesis, there is still insufficient data to understand the important role of the host immune system in triggering clinical signs and the reproductive management is still an effective preventive method for disease perpetuation.

Demodicosis is a parasitic disease caused by the imbalance in the number of mites of the genus Demodex sp. The skin scraping is the gold standard method for diagnosis, but other methods can be used. Based on this, the aim of this work is to report cases in which cytology served as an auxiliary diagnosis for demodectic mange. Two dogs went to a private clinic with skin lesion of different aspects and in which both dogs the cytology was performed by skin imprint, being possible to observe the presence of Demodex canis. Thus, cytology could be used as an auxiliary diagnostic method this disease.

Introducción. Se conoce como demodex al ácaro que vive en la piel de los mamíferos, pero cuando el sistema inmune se ve afectado la población del ácaro aumenta provocando demodicosis, siendo esta una patología dermatológica común, se da por la excesiva proliferación del ácaro, el sistema inmunitario de los perros juego un rol imprescindible frente al equilibrio de la población del ácaro cuando los animales están sanos y en el desarrollo de esta enfermedad cuando el animal está enfermo, lo que lleva a un estrés oxidativo. Objetivo. La presente revisión bibliográfica ayudara a conocer los datos actuales sobre generalidades del ácaro forma de propagación, aspectos clínicos, patología, diagnósticos y tratamientos actualizados para una terapia adecuada. Metodología. Esta revisión bibliográfica se hizo mediante exploración minuciosa en diferentes revistas, tesis, bases de datos como Scielo, Google Académico, Mendeley, ResearchGate, Pubmed y libros, por medio de las siguientes palabras claves “demodicosis”, “ácaro”, “demodex canis” y “parásito”. Conclusiones. La demodicosis canina es una patología parasitaria que afecta a perros de cualquier edad, aunque no es contagiosa se puede transmitir de madre a cachorros en el amamantamiento, es muy importante cuidar a las mascotas manteniéndolas sanas, para que tengan un correcto funcionamiento del sistema inmunitario. Área de estudio general: Medicina Veterinaria. Área de estudio específica: Dermatología. Tipo de estudio: Revisión Bibliográfica.
