🦠 Streptococcosis in Guinea Pigs: A Vet’s 2025 Guide with Dr Duncan Houston BVSc 🐹🩺

By Dr Duncan Houston BVSc – Streptococcosis, caused by various Streptococcus species, can present as respiratory illness, ear infections, lymph node swelling, or systemic disease in guinea pigs. This guide covers causes, symptoms, diagnosis, treatment, prevention, and recovery in 2025. 🧬✨

📘 What Is Streptococcosis?

Streptococcosis refers to infections caused by Streptococcus bacteria—particularly S. pneumoniae and S. zooepidemicus. These gram-positive cocci can cause pneumonia, otitis media, lymphadenitis, arthritis, and acute systemic illness. Guinea pigs may harbour these bacteria without signs, then become sick during stress. :contentReference[oaicite:3]{index=3}

🐾 Common Causes & Risk Factors

• Asymptomatic carriers can shed via sneezing/coughing; stress often triggers disease :contentReference[oaicite:4]{index=4}.
• Damp, unhygienic conditions allow bacteria to flourish :contentReference[oaicite:5]{index=5}.
• Cohabitation with other species like rabbits or dogs can introduce Bordetella, complicating infection :contentReference[oaicite:6]{index=6}.
• Youth, age, illness or immune suppression heighten vulnerability :contentReference[oaicite:7]{index=7}.

⚠️ Clinical Signs: Look for These Clues

• 🐽 Sneezing, nasal discharge, wheezing, labored breathing :contentReference[oaicite:8]{index=8}.
• 👂 Ear symptoms: head tilt, incoordination, discharge :contentReference[oaicite:9]{index=9}.
• 📦 Swollen lymph nodes, especially cervical :contentReference[oaicite:10]{index=10}.
• 🦴 Lameness or joint swelling (“Strep arthritis”) :contentReference[oaicite:11]{index=11}.
• 😓 Depression, fever, sudden anorexia, unexplained death – disease can escalate rapidly :contentReference[oaicite:12]{index=12}.

🔬 Diagnosing Streptococcosis

Your veterinarian will combine history, exam, and tests:

• Physical exam + auscultation for lung/ear sounds.
• Nasal, ear swabs or lymph node aspirates for bacterial culture and sensitivity :contentReference[oaicite:13]{index=13}.
• Bloodwork (CBC, biochemistry) to evaluate systemic signs.
• Imaging such as X-rays or ultrasound to identify pneumonia, joint or ear involvement :contentReference[oaicite:14]{index=14}.

💊 Treatment & Medical Management

✅ Antibiotic Therapy

Effective antibiotics depend on culture results:

• Common choices: trimethoprim‑sulfa, chloramphenicol, enrofloxacin, penicillin – chosen based on sensitivity :contentReference[oaicite:15]{index=15}.
• Treatment often lasts 2–4 weeks or until full recovery.

🩺 Supportive Care

• 💧 Subcutaneous fluids to prevent dehydration.
• 💨 Nebulization or oxygen therapy for respiratory relief.
• 🍼 Syringe feeding of palatable, vitamin C–rich diets.
• 🌡️ Warm, stress‑free recovery space to aid healing.

🏥 Specific Cases

• Otitis media/inner ear: May need ear flushing, prolonged antibiotics, anti-inflammatories :contentReference[oaicite:16]{index=16}.
• Arthritis: NSAIDs for inflammation, joint supplements may help.
• Lymphadenitis: May require draining or surgical removal of abscessed nodes :contentReference[oaicite:17]{index=17}.

📈 Prognosis & Recovery

• 🟢 Early-treated localized infections usually resolve completely.
• 🟡 Severe pneumonia or systemic spread lowers survival rate; chronic sequelae like lung scarring or hearing loss can occur :contentReference[oaicite:18]{index=18}.
• ⚠️ Untreated or advanced cases may be life-threatening.

🛡️ Prevention Strategies

• 🏡 Maintain clean habitat: spot-clean daily; deep clean weekly.
• 📏 Avoid overcrowding; keep humidity moderate (≈50‑60 %).
• 📦 Quarantine all new animals for 2–4 weeks with veterinary screens.
• 🐾 No cohabitation with rabbits or dogs/cats to reduce exposure :contentReference[oaicite:19]{index=19}.
• 🥗 Balanced diet and reduce stress to fortify immunity.
