🐹 Salmonellosis in Guinea Pigs: A Vet’s 2025 Guide by Dr Duncan Houston BVSc 🩺

By Dr Duncan Houston BVSc – Salmonellosis is a serious bacterial infection that can affect guinea pigs—and people. In this comprehensive 2025 guide, learn about its causes, zoonotic risks, signs, diagnosis, treatment, prevention, and safe handling protocols to protect your pet and family. 🌟

📘 What is Salmonellosis?

Salmonellosis is caused by gram-negative Salmonella bacteria (e.g., S. Enteritidis, S. typhimurium). Guinea pigs may shed Salmonella in their feces—even when asymptomatic. Infection can lead to diarrhoea, systemic disease, and death. Humans are also at risk through contact. :contentReference[oaicite:3]{index=3}

🐾 How It Spreads

• Fecal–oral route: contaminated bedding, food, water, or surfaces.
• Direct contact with infected or carrier animals.
• Zoonotic transfer to humans handling pets or cleaning cages. :contentReference[oaicite:4]{index=4}

⚠️ Zoonotic Risk & Outbreak Concerns

Several human outbreaks traced back to guinea pigs have occurred—especially in children—highlighting the importance of hygiene. Even healthy-appearing pets can carry Salmonella. :contentReference[oaicite:5]{index=5}

📌 Risk Factors

• Young, elderly, or immunocompromised pigs.
• Stress: overcrowding, transport, environmental changes.
• Poor husbandry: dirty cages, old bedding, lack of sanitation.
• Introduction of new or unquarantined animals.

🩺 Clinical Signs in Guinea Pigs

• 💧 Diarrhoea (may be watery or bloody).
• 😓 Lethargy, anorexia, weight loss.
• 🧬 Reproductive issues: stillbirths, infertility.
• ⚠️ Sudden death in rapid systemic cases. :contentReference[oaicite:6]{index=6}

🔬 Diagnosis Methods

• Fecal culture or PCR testing.
• Bloodwork to assess systemic infection.
• Necropsy in fatal cases confirming tissue infection and pathology.

💊 Treatment & Veterinary Care

• Systemic antibiotics (e.g., sulfonamides, chloramphenicol)—based on sensitivity testing.
• Fluid therapy (oral or subcutaneous) to prevent dehydration.
• Sterile diet: easily digested pelleted food and soaked hay.
• Symptomatic care: anti‑inflammatories, warmth, isolation.

🏡 Environmental Management

• Isolate sick and carrier animals immediately.
• Discard contaminated bedding. Disinfect all surfaces with bleach solution. :contentReference[oaicite:7]{index=7}
• Quarantine new guinea pigs for at least 4 weeks with testing before introduction.
• Wash hands thoroughly after handling or cleaning cages. :contentReference[oaicite:8]{index=8}

🛡️ Prevention Strategies

• Strict hygiene protocols: clean cages weekly and spot clean daily.
• No kissing or face-contact; avoid eating near cages. :contentReference[oaicite:9]{index=9}
• Avoid children under 5, elderly, pregnant individuals, or immunocompromised from handling pets. :contentReference[oaicite:10]{index=10}
• Purchase from reputable breeders with strong biosecurity (‘closed colony’ systems).
