Characterization of otic bacteria microbiota in dogs.
Otitis externa is one of the most common reasons for veterinary visits, but little had been known about the microbiota of a heathy ear. A study was performed to compare microbiota in normal dogs compared to those with otitis externa. Samples of DNA were taken from 18 dogs with confirmed otitis and 8 in dogs with healthy ear and were isolated and sequenced. The study showed that otitis externa is accompanied by broad and complex differences in the microbiota.
Bacteria from 27 different phyla were identified.
Ears belonging to dogs with otitis had significantly decreased alpha diversity when compared to healthy ears.
Staphylococcus, Pseudomonas and Parvimonas, were over represented in dogs with otitis
