Abstract

We report a case of Streptococcus canis-induced severe soft tissue infection (SSTI) in the left hindlimb of a miniature dachshund (male/13-year-old), with septic shock. The dog underwent immediate exploration/debridement of necrotic area in the hindlimb, with imipenem administration after culture sampling. The pathogen was isolated from necrotic tissue and blood, and then identified using mass spectrometry/molecular characterization (sequence type 9 harboring M-like protein allele 1). The dog experienced recurrent soft tissue inflammation in the hindlimb 115 days after onset and received ampicillin treatment, after which the dog was cured without further recurrence. This is the first report of an animal cured of SSTI in Japan. S. canis should be considered a causative bacterium when examining/treating animals with SSTI and recurrence.
