Streptococcus spp are a common commensal bacteria which cause respiratory and skin diseases in guinea pigs worldwide.
Species which are pathogenic to guinea pigs include:
- Streptococcus equi zooepidemicus
- Streptococcus pneumoniae
- Streptococcus pyogenes (septic arthritis)
Guinea pigs clinically affected by Streptococcus equi zooepidemicus often show signs of respiratory disease such as fever, dyspnea, coughing, anorexia and lethargy. Abrasions of the mouth are a common site for bacterial entry into the circulation. Streptococcus pneumoniae is usually associated with upper respiratory disease.
Treatment usually involves use of a broad-spectrum antimicrobial such chloramphenicol (50 mg/kg, PO, bid for 14 days).
Diagnosis is based on presenting clinical signs supported by isolation of Streptococcus spp bacteria on agar culture.
