13 was resistant towards the anti-methicillin-resistant Staphylococcus aureus drugs, vancomycin and linezolid. Conclusion: Though antibiotic-resistant strains of S. canis are isolated at a high price, they could at present be treated with -lactamase-inhibiting penicillins. CC13 can be a pathogenic cluster with higher levels of antibiotics resistance. Keywords and phrases: Dogs, Streptococcus, Antibiotic resistance, Multilocus sequence typing, Pyoderma, Oral cavity, Betalactamase, Opportunistic infections Background Canine deep pyoderma can be a bacterial infection that affects tissues deeper than the epidermis, for example cellulitis and furunculosis [1]. The improvement of drug resistance by pathogenic bacteria is actually a critical problem for the therapy of pyoderma [2]. The current recommendation for deep pyoderma would be to treat to get a minimum of 60 weeks with a maximum dose of systemic antibiotics [1].

Streptococcus canis is recognized to be among the causative gram-positive cocci of deep pyoderma in dogs and humans [1, 4]. S. canis-associated deep pyoderma from time to time causes a potentially fatal prognosis [5]. It is also vital as a zoonotic pathogen mainly because keeping dogs with S. canis puts their owners at threat of creating deep pyoderma [6]. However, scant signalment details on S. canis-associated deep pyoderma has been reported toThe Author(s) 2022.

S. canis is often a -hemolytic Lancefield group G streptococcus, which colonizes the skin, the oral cavity, the upper respiratory tract, along with the reproductive tract of dogs [7, 8]. S. canis-associated deep pyoderma is thought to become an opportunistic infection, with resident bacteria infecting the destroyed skin [1, 9]. Streptococci dominate the oral cavity of dogs, and S. canis is endemic [10, 11]. Since dogs have a tendency to lick their wounds when their skin is broken, opportunistic infection in the oral cavity is suspected,.
