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

By Dr Duncan Houston BVSc – Pneumonia is one of the most critical and common respiratory diseases affecting guinea pigs. In this comprehensive 2025 guide, we’ll cover the causes, symptoms, diagnostics, treatments, supportive care, and prevention strategies to protect your piggies’ lung health. 🧬✨

📘 What Is Pneumonia?

Pneumonia is inflammation and infection of lung tissue and airways. It can be caused by:

• Bacterial pathogens: Bordetella bronchiseptica, Streptococcus pneumoniae, Streptococcus zooepidemicus :contentReference[oaicite:3]{index=3}
• Viral causes: Guinea pig adenovirus (GPAdV), less common :contentReference[oaicite:4]{index=4}
• Complex infections: Secondary ear infections, systemic spread :contentReference[oaicite:5]{index=5}

Whether bacterial or viral, pneumonia disrupts air exchange, leading to serious breathing issues and, in severe cases, death.

🐾 Who Is at Risk?

• Young or old guinea pigs: Weakened immune systems make them vulnerable :contentReference[oaicite:6]{index=6}
• Stressors: Drafts, poor hygiene, overcrowding, or other illness :contentReference[oaicite:7]{index=7}
• Close contact with other pets: Rabbits, dogs, and cats may carry Bordetella without signs :contentReference[oaicite:8]{index=8}

⚠️ Signs to Watch For

Pneumonia symptoms can escalate quickly. Common red flags:

• 💨 Fast, shallow, or labored breathing—wheezing, crackles
• 😓 Lethargy, dull coat, loss of appetite
• 👃 Nasal or ocular discharge, sneezing, coughing
• 🌡️ Fever, weight loss, poor body condition
• 🌀 Head tilt or incoordination if middle-ear involved :contentReference[oaicite:9]{index=9}
• ❗Open-mouth breathing requires immediate vet attention :contentReference[oaicite:10]{index=10}

🔬 Diagnosis & Testing

Accurate diagnosis guides treatment:

• 🩺 Physical exam including auscultation for abnormal lung sounds
• 🖼️ Chest X-rays or CT scans to confirm pneumonia :contentReference[oaicite:11]{index=11}
• 🧪 Deep nasal/tracheal swabs for culture or PCR, and possible ear aspiration
• 🩸 Bloodwork & urinalysis to assess systemic health and vitamin C status :contentReference[oaicite:12]{index=12}

💊 Treatment Strategies 2025

✅ Antibiotics for Bacterial Pneumonia

Effective options under vet guidance include:

• Trimethoprim‑sulfa, chloramphenicol, enrofloxacin—selected via culture sensitivity :contentReference[oaicite:13]{index=13}
• Long courses—typically 2–4 weeks—to fully resolve infection

🩺 Supportive & Emergency Care

• 💧 Subcutaneous fluids to prevent dehydration
• 🍼 Syringe feeding of high-fibre, vitamin C–rich food
• 💨 Oxygen and nebulization to ease breathing and airway hydration
• 💊 Vitamin C supplementation supports immune response :contentReference[oaicite:14]{index=14}
• 🧩 Diuretics or mucolytic agents may aid mucus clearance :contentReference[oaicite:15]{index=15}

🏥 Hospitalization & Intensive Monitoring

• IV fluids and constant oxygen support
• Frequent physical assessments
• Additional diagnostics if ear infections, abscesses, or systemic issues are suspected

🔁 Prognosis & Recovery

Outcomes depend on early detection and type of infection:

• 🟢 Bacterial cases managed early often recover fully; lung scarring may predispose to future infections :contentReference[oaicite:16]{index=16}
• ⚠️ Viral (adenovirus) pneumonia can be mild or fatal—no direct cure, supportive care only :contentReference[oaicite:17]{index=17}
• 🟡 Some recover with chronic issues; mild ongoing cough may persist
• 🔴 Severe or late-diagnosed cases risk fatality—prompt action is vital
• 🧬 Reddit cases often note poor recovery, but some owners report improvement with aggressive treatment :contentReference[oaicite:18]{index=18}

🧼 Prevention & Husbandry Tips

• 🏡 Hygienic housing with regular cleaning to avoid pathogen buildup
• 📏 Avoid drafts and temperature extremes; ideal range 65–75 °F :contentReference[oaicite:19]{index=19}
• 📦 Quarantine — especially when introducing new pets (minimum 2–4 weeks)
• 🚫 Avoid cohabitation with rabbits, dogs or cats that can carry Bordetella :contentReference[oaicite:20]{index=20}
• 🍽️ Balanced diet with vitamin C to support immunity
• 📝 Regular vet check-ups for early breathing issues detection
