Vet Guide 2025: Skin & Shell Infections in Reptiles 🦎 by Dr Duncan Houston 🩺

Hello! I’m Dr Duncan Houston, BVSc and founder of Ask A Vet. Reptile skin and shell infections are common but often overlooked. Left untreated, they can lead to serious complications, including tissue necrosis, systemic illness, or persistent discomfort. In this detailed 2025 guide, I explain the causes, diagnosis, treatment, environmental factors, surgical interventions, and prevention strategies for skin and shell infections in reptiles—ensuring your pet stays healthy and thriving.

1. Common Types & Causes

Reptile skin and shell infections often result from:

• Bacterial overgrowth—dirty substrate or wounds create ideal conditions.
• Fungal invasion—especially in humid environments.
• Abscesses: localized infection pockets filled with pus; reptiles cannot reabsorb them naturally :contentReference[oaicite:3]{index=3}.
• Shell Rot in turtles/tortoises—progressive infection of scutes under poor moisture or hygiene :contentReference[oaicite:4]{index=4}.

2. Recognizing Clinical Signs

• Red, swollen, ulcerated skin or scutes
• Discharge (pus, odour, moisture)
• Limping, lethargy, appetite loss
• Shell cracking, discoloration, soft spots in turtles/tortoises
• Visible lumps—likely abscesses that will not drain naturally :contentReference[oaicite:5]{index=5}

3. Diagnostic Approach

• Visual exam: inspect wound margins, shell condition, and plate integrity.
• Fine-needle aspirate: collect fluid/cells—bacteria, fungi, or pus :contentReference[oaicite:6]{index=6}.
• Culture & sensitivity tests: identify pathogen and antibiotic resistance.
• Imaging: X-rays/ultrasound detect deep or internal infection foci.

4. Treatment Pathways

a. Wound Care & Debridement

• Clean area with reptile-safe antiseptic (diluted chlorhexidine, diluted povidone-iodine)
• Debride necrotic tissue under sedation
• Apply topical antibacterial or antifungal ointments

b. Abscess Management

Abscesses in reptiles typically require surgical removal or manual drainage—reptiles lack the enzymes to reabsorb pus naturally :contentReference[oaicite:7]{index=7}. Sedation is essential, followed by antibiotic therapy to prevent recurrence.

c. Shell Rot Treatments

• Clean and debride affected scutes
• Topical antimicrobials applied to clean surface
• Maintain dry basking area for healing
• Oral or injectable antibiotics in severe or recurrent cases

d. Systemic Antibiotics & Supportive Care

• Targeted antibiotic course based on culture
• Fluid therapy for hydration
• Heating to support immune response
• Pain control—NSAIDs or opioids as prescribed

5. Surgical Interventions & Follow-Up

• Remove necrotic or infected tissue
• In severe shell rot—excise affected scutes or bone
• Close wounds carefully; recheck for integrity and infection avoidance
• Follow-up visits for wound monitoring and culture rechecks

6. Environmental & Husbandry Corrections

• Clean and disinfect habitats weekly; deep clean monthly
• Replace damp substrate and décor
• Adjust heat/humidity—dry for bacterial healing, moderate for fungal areas
• Provide dry basking zones for turtles/tortoises
• Quarantine affected individuals until full recovery

7. Prevention & Owner Responsibilities

• Routine health checks including skin and shell
• Adequate hygiene: hand-wash post-handling, habitat cleaning
• Maintain balanced temperature and UVB exposure
• Separate enclosures to prevent cross-contamination
• Prompt treatment of minor injuries to prevent infection

8. When to Contact a Reptile Vet

• Persistent ulcerations, abscesses, or shell decay
• Sick appearance: lethargy, anorexia, weight loss
• Infections recuring despite initial treatment
• Visible necrotic tissue requiring debridement
