Identificação e teste de sensibilidade aos antimicrobianos de bactérias em amostras otológicas de caninos com hipercortisolismo e hipotireoidismo – estudo de caso controle pareado

Abstract

Otitis is a syndrome that affects dogs and cats quite frequently in clinical routine and is caused by several factor that lead to a exacerbated growth of bacteria and fungi. The endocrinopathies, hypothyroidism and hypercortisolism, induce dermatological changes in most animals, including the ear canal and can be a reason for this otitis. The following study had as objective identify the rate between the presence of otitis and endocrinopathy in dogs. To be evaluated this ratio was made a paired case-control study, which was collected otological samples of 20 animals, 10 animals patients with hypercortisolism or hypothyroidism, and 10 healthy animals in a perfect match with the endocrinopaths. Posteriorly was made the bacterial profile, antimicrobial disk susceptibility tests and cytology of every sample. It was identified bacterial growth, suggestive of Staphylococcus spp in 25% of the samples and presence of Malassezia yeast in 30% of the cytologic samples. Due to the reduced number of animals in this study, it was not possible correlate the endocrinopathies with the presence of otitis.
