Plain-English summary
A horse in Ontario developed an abscess, which is a pocket of infection, in the lymph node under its jaw. This abscess was caused by a bacteria called Actinomyces denticolens, which is known to take advantage of weakened immune systems. The symptoms of this infection can look a lot like another illness called strangles, so it's important for veterinarians to consider this bacteria when diagnosing similar cases. This report highlights the need for awareness of this specific pathogen in horses with swollen lymph nodes.
Abstract
This is the first report of the isolation of Actinomyces denticolens, an opportunistic pathogen, from a draining submandibular lymph node abscess in a horse in Ontario. Due to the similarity of the clinical signs with strangles, this pathogen should be included in the differential diagnosis of submandibular lymphadenopathy in the horse.
