Original publication title: Microbiology of Otitis externa in dogs reveals wide variation in Staphylococcus species.

Plain-English summary
A group of 24 dogs with ear infections (otitis externa) was tested to find out which types of Staphylococcus bacteria were causing the problem. The most common bacteria found were Staphylococcus pseudintermedius and Staphylococcus schleiferi, but less common types like Staphylococcus simulans and Staphylococcus haemolyticus were also identified. These findings highlight the need for more research to understand which bacteria are most important for treating ear infections in dogs. If your dog has an ear infection, your vet may test for these bacteria to determine the best treatment.

Abstract
Bacterial infections are a major cause of otitis externa in dogs, with Staphylococcus species frequently implicated. This study analyzed samples from 24 dogs with otitis externa to identify the Staphylococcus species involved. The isolates included Staphylococcus pseudintermedius, Staphylococcus schleiferi, Staphylococcus simulans, and Staphylococcus haemolyticus. While S. pseudintermedius and S. schleiferi are well-recognized pathogens in canine otitis externa, S. simulans and S. haemolyticus are rarely reported. Given their zoonotic potential, these findings emphasize the importance of further investigations to clarify the microbiology of otitis externa and to identify the pathogens of greatest clinical relevance.
