To Lick One's Wounds: A Case of Pasteurella Canis Oralis Osteomyelitis and Neisseria Animaloris Infection from Canine Saliva

The complications of wound infections caused by animal related trauma are well known and explored. Of the numerous polymicrobial etiologies, Neisseria animaloris and Pasteurella canis oralis have been reported only in a limited number of cases. This manuscript explores the rare finding of these species in the case of an 83-year-old male with a diabetic foot wound complicated by infection from the saliva of his pet dog. The case highlights the first instance of P. canis oralis without the setting of a penetrating animal bite, emphasizing the vulnerability of open lesions in patients whose comorbidities impair proper wound healing. These bacteria are susceptible to beta-lactams with beta-lactamase inhibitors and can be treated once identified. It is crucial to recognize rare pathogens and initiate appropriate treatment early, and to emphasize proper wound care, especially in the context of pet interactions.
