Résumé
Every basic course in microbiology teaches us, Streptococcus canis always tests positive for Lancefield group G. Surprisingly, we identified a strain of S. canis with Lancefield group C, cultured from a dog with otitis externa after lateral ear canal resection. Whole genome sequencing data and analysis points towards a horizontal gene transfer event between S. canis and S. dysgalactiae. Although these species are closely related, gene transfer in this region of the genome of S. canis has not been described before. The value of technologies as MALDI-TOF MS and sequencing in microbiological diagnostics will grow as more diverse streptococci arise that do not always conform anymore to the classical Lancefield group typing.
