We describe a case of septicemia due to Streptococcus canis in a 77-year-old man. The organism was presumably transmitted from a domestic animal. Ulcers of the lower limbs were the likely portals of entry. The differentiation between Streptococcus canis and Streptococcus dysgalactiae was based on biochemical properties and DNA macrorestriction analysis by pulsed-field gel electrophoresis. 
Recurrent septicemia caused by Streptococcus canis after a dog bite.
A case of septicemia with cellulitis caused by S. canis in a 75-y-old woman, which developed 2 weeks after a dog bite, is described, which demonstrated that the organism had been transmitted by means of a dog Bite to her hand.
Endocarditis caused by Streptococcus canis: an emerging zoonosis?
A human case of infective endocarditis caused by Streptococcus canis related zoonotic invasive infections may have been previously underdiagnosed due to inadequate identification of group G StrePTococcus species.

A 91-year-old dog-owning woman with a history of hypertension and femoral neck fracture consulted the authors' hospital with fever and femur pain with redness recovered completely without critical illness following prompt antimicrobial treatment with ceftriaxone.
Caso fatal por Streptococcus canis multirresistente
The occurrence of a fatal case of septicaemia in a pinscher dog by multiresistant Streptococcus canis is described and its high resistance to antimicrobial drugs routinely used in veterinary medicine is emphasized.
Bacteremia Caused by Group G Streptococci, Taiwan
A retrospective observational study in Taiwan, 1998–2004, identified 92 patients with group G streptococcal bacteremia; 86 had Streptococcus dysgalactiae subspecies equisimilis and resistance to quinupristin-dalfopristin was high.
Human native endocarditis caused by Streptococcus canis—a case report
A 73-year-old woman living in close contact with her dog was diagnosed with a very rare case of Streptococcus canis native infective endocarditis in a 73‐year‐old woman, who fully recovered.


Primary peritonitis due to group G Streptococcus: A case report.
A rare, life-threatening, acute illness, primary peritonitis, due to Beta-hemolytic Streptococcus group G, whose etiological source probably was a family dog is reported.
Group G streptococcal infections.
Group G streptococcal epizootic in a closed cat colony
An epizootic of beta-hemolytic Lancefield group G streptococcal infections occurred in a specific-pathogen-free colony of laboratory cats and was finally eradicated from the colony by depopulating the affected building.
Group G streptococcal bacteremia: clinical study and review of the literature.
The most frequent portal of entry was the skin, usually in cases with preexisting edema due to previous surgical removal, irradiation, or tumor infiltration of lymph nodes, or to chronic venous insufficiency.
Infections Due to Lancefield Group G Streptococci
The group G streptococcus has surfaced in the past 10 to 15 years as an important opportunistic and nosocomial pathogen, and in patients with septic arthritis, prosthetic devices, prior joint disease and immunosuppressive diseases and therapy often adversely influence the response to antibiotic therapy.
Streptococcus canis sp. nov.: A Species of Group G Streptococci from Animals
Animal group G strains from cows with mastitis and from dogs with different pathological conditions were characterized and named Streptococcus canis sp.
Biochemical differences among human and animal streptococci of Lancefield group C or group G.
It was confirmed that fermentation tests were helpful in the study of S. equi and S. zooepidemicus and that enzyme reactions helped distinguish between S. canis and the human strains of group G.
Serogroups and biotypes among beta-hemolytic streptococci of canine origin
Most of the strains originated from skin, subcutaneous and wound infections, genitourinary lesions, otitis externa, and respiratory disease, and data suggest that group G streptococci may be preferentially parasites of the urogenital tract.
Biotyping and exoenzyme profiling as an aid in the differentiation of human from bovine group G streptococci
The concept of two distinctly different epidemiological reservoirs of group G streptococci in humans and bovines is supported.
