The otitis media is defined as an inflammation of the middle ear. In dogs, this condition is one of the most common causes of maintaining recurrent otitis externa. Both aerobic and anaerobic bacteria are present in the diseased tympanic bulla, and in some circumstances, it becomes difficult to determine what role these microorganisms play. Although the aerobic microbiota is frequently studied in dogs with ear diseases, little data is available on the strict anaerobic microorganisms present in the ears of these patients. In this report, the isolation of the anaerobic bacteria Peptostreptococcus indolicus is revealed in the exudate of an adult Saint Bernard dog breed with bilateral chronic otitis media, being the first description in the veterinary literature related to the presence of this bacterial species in canine otitis media. Based on this finding, it is suggested that anaerobic bacteria such as P. indolicus may be related to the infectious process of the middle ear in dogs.
