Group C and group G streptococci include several species of bacteria, with the main human pathogen being Streptococcus dysgalactiae ssp. equisimilis. These bacteria usually cause throat, skin and soft tissue infections.
Group C and group G streptococci can also cause invasive infections like:
endocarditis (inflammation of the lining of the heart)
bone and joint infections
Toxic shock can follow both localised and invasive infections.
Group C and G streptococcal infections are spread by person to person contact, such as sneezing, coughing, or touching an open wound.
Group C and G streptococcal infections may be treated with antibiotics.
