Determinación de Malassezia spp en perros en el Cantón Marcelino Maridueña

The principle of this project was to demonstrate and determine the presence of Malassezia spp. in patients with canine atopic dermatitis (CAD); through microscopic observation of cytology, swabs, skin scraping and adhesive tape technique; dyed with Diff-Quick stain. These samples were taken from five body areas: interdigital spaces of the pelvic and thoracic limbs, corners of the lips, perineum, right and left ears, and armpits. Out of a total of 100 dogs examined with canine atopic dermatitis in the Marcelino Maridueña Canton, the overgrowth of Malassezia spp. For the statistical analysis, Chi square tests were used to see the dependence between the variables and it was found that no variable is dependent; According to the study carried out, it is concluded that the incidence of Malassezia Pachydermatis in canines from the Coronel Marcelino Maridueña Canton was 51%. Observing a higher percentage incidence of 53% in canines in the 12 to 108 month category, presenting 27 positive cases of the disease. Also, a higher percentage presence of Malassezia spp was found in males with 53%, without this meaning that the sex variable is a determinant in the positive diagnosis of the disease. On the other hand, the presence of the disease is monitored in 53% mixed-breed canines, despite the fact that the breeds are not a determining factor in the incidence of the disease, but rather the conditions in which the animal lives.

El presente proyecto tuvo por principio evidenciar y determinar la presencia de Malassezia spp. en pacientes con dermatitis atópica canina (DAC); mediante la observación microscópica de citologías, hisopados, raspado cutáneo y técnica de cinta adhesiva; teñidas con la coloración de Diff-Quick. Estas muestras se tomaron de cinco zonas corporales: espacios interdigitales de los miembros pélvicos y torácicos, comisuras de los labios, periné, oídos derecho e izquierdo y axilas. Sobre un total de 100 perros examinados con dermatitis atópica canina en el Cantón Marcelino Maridueña, se valoró el sobrecrecimiento de Malassezia spp. Para el análisis estadístico se utilizó pruebas de Chi cuadrado para ver la dependencia entre las variables y se encontró que ninguna variable es dependiente; De acuerdo al estudio realizado, se concluye que la incidencia de la Malassezia Pachydermatis en caninos del Cantón Coronel Marcelino Maridueña fue de 51%. Observándose una mayor incidencia porcentual del 53 % en caninos de la categoría de 12 a 108 meses, presentando 27 casos positivos de la enfermedad. También, se encontró mayor presencia porcentual de Malassezia spp en machos con el 53 %, sin que esto signifique que la variable sexo sea una determinante en el diagnóstico positivo de la enfermedad. Por otra parte, se observó presencia de la enfermedad en caninos mestizos 53 %, a pesar de que las razas no son una determinante en la incidencia de la enfermedad, sino las condiciones en las que hábitat el animal.
