Cytologic detection of Simonsiella‐like bacteria suggesting oral contamination in cases of canine ulcerative keratitis

Abstract

AbstractSimonsiella is a known oral commensal organism and has been identified as a part of the normal ocular microbiota in humans. This case series highlights three cases of canine ulcerative keratitis in which a mixed bacterial infection, including high numbers of Simonsiella spp. had been identified cytologically. All cases had episodes of oral contamination, either from licking the eye, licking the paws and rubbing the eye, or housemate(s) licking the eye. In two of three cases, ulcer resolution was observed within 3 weeks following initiation of broad‐spectrum topical antimicrobial therapy.
