Vet Guide 2025: Infectious Cloacitis in Reptiles & Amphibians 🦎🐸 by Dr Duncan Houston 🩺

Hello! I’m Dr Duncan Houston, BVSc and founder of Ask A Vet. Infectious cloacitis is a painful, often serious condition where the cloaca—the shared exit for digestive, urinary, and reproductive tracts—becomes inflamed or infected. In this extensive 2025 guide, I’ll explain why it happens, how to spot it quickly, diagnostic strategies, medical and surgical options, and how improving cage hygiene can prevent recurrence.

1. ⛑️ What Is Infectious Cloacitis?

Cloacitis refers to inflammation or infection of the cloaca or vent region. It may appear as swelling, redness, ulceration, bleeding, or abnormal discharge from the cloacal opening :contentReference[oaicite:3]{index=3}.

2. Why It Happens (Causes)

• Bacterial infection is most frequent (e.g., Aeromonas, Pseudomonas), often following trauma or moisture buildup :contentReference[oaicite:4]{index=4}.
• Internal irritants: parasites or fecaliths/uroliths may lodge and damage cloacal lining :contentReference[oaicite:5]{index=5}.
• Reproductive issues: retained eggs, prolapse-related inflammation contribute in turtles, lizards, and amphibians :contentReference[oaicite:6]{index=6}.
• Systemic spread: infections may extend beneath skin or into organs if untreated :contentReference[oaicite:7]{index=7}.

3. Who Gets It & When

• All reptile and amphibian species—but especially turtles, tortoises, snakes, lizards, and egg-binding species.
• High-risk situations: moist or soiled enclosures, breeding activity, poor substrate hygiene, trauma near vent region :contentReference[oaicite:8]{index=8}.

4. Signs You Should Never Ignore

• Swollen, reddened vent; painful to touch :contentReference[oaicite:9]{index=9}.
• Bloody or pus-like discharge :contentReference[oaicite:10]{index=10}.
• Straining during defecation or urination
• Appetite loss, lethargy, weight loss
• Evidence of cloacal stones on X-ray
• Concurrent issues: prolapse, retained eggs, visible parasites

5. Diagnostic Strategy

• Physical exam: vent inspection and palpation of cloaca :contentReference[oaicite:11]{index=11}.
• Fecal analysis: to detect parasites that may cause cloacal irritation :contentReference[oaicite:12]{index=12}.
• Cytology and culture: swabs to identify infectious agents and guide antibiotics :contentReference[oaicite:13]{index=13}.
• Imaging: X-ray or ultrasound detect cloacoliths, stones, abscesses, or cloacal prolapse :contentReference[oaicite:14]{index=14}.

6. Treatment Options

6.1 ⏳ Medical Management

• Systemic antibiotics based on culture (e.g., enrofloxacin, ceftazidime) for ≥7–14 days :contentReference[oaicite:15]{index=15}.
• Antiparasitic therapy if parasites are present :contentReference[oaicite:16]{index=16}.
• Warm soaks and antiseptic wound care to clean and reduce inflammation.
• Pain relief (NSAIDs) and supportive fluids/nutrition.

6.2 🛠️ Surgical & Manual Intervention

• Removal of cloacal stones (cloacoliths) :contentReference[oaicite:17]{index=17}.
• Debridement of necrotic tissue or abscesses, with local antibiotic application.
• Reduction and repair of prolapse when necessary.

7. Environmental & Husbandry Update

• Use dry or non-stick substrate to keep the vent area clean.
• Clean enclosures daily; perform weekly disinfecting.
• Maintain proper thermal gradients and humidity to support immune health.
• Separate affected animals until fully recovered.

8. 🚨 When to Contact Your Vet

• Persistent swelling, discharge, or pain lasting >48 hrs.
• Straining, loss of appetite, lethargy.
• Visible stones, prolapse, or parasites.
• Poor response to initial treatment—vet check for culture re-testing or imaging.

10. Final Thoughts

Infectious cloacitis is more than a minor irritation—it can lead to deep infection, abscesses, cloacal stones, or reproductive issues when ignored. In 2025, prompt diagnosis, evidence-based treatment, and habitat improvements are essential. With vigilance, owner care, and Ask A Vet support, your reptile or amphibian can recover fully and remain healthy well into the future. 🩺🌿
