Summary
This study identifies Streptococcus canis (S. canis) as a cause of feline monarthritis. Penicillin and streptomycin treatment showed effectiveness in most affected cats.
Area of Science:
- Veterinary Medicine
- Microbiology
- Pathology
Background:
- Streptococcus canis (S. canis) is a bacterium of Lancefield serologic group G.
- S. canis has been sporadically identified in various purulent infections since 1980.
- Feline arthritis caused by S. canis has not been previously described.
Purpose of the Study:
- To describe a novel pathologic condition in cats: monarthritis caused by Streptococcus canis.
- To report on the incidence and characteristics of S. canis-induced arthritis in a closed cat breeding colony.
Main Methods:
- Case series reporting six cases of feline monarthritis in 1988 and one in 1990.
- Bacterial isolation and identification of Streptococcus canis.
- Therapeutic outcomes with penicillin and streptomycin were documented.
Main Results:
- Six cases of feline monarthritis attributed to Streptococcus canis occurred within a six-month period in 1988.
- An additional case was recorded in 1990.
- Four out of six treated cats recovered fully following penicillin and streptomycin therapy.
- S. canis has been previously isolated from purulent processes, including one prior case of purulent arthritis in 1982.
Conclusions:
- Streptococcus canis is identified as a causative agent of feline monarthritis.
- High inbreeding within the colony may have contributed to the cluster of cases.
- Cats and humans appear to be more frequently affected by S. canis compared to other species.
- Similarities exist between S. canis-induced arthritis in cats and humans, suggesting potential zoonotic implications.
