By Dr Duncan Houston BVSc – avian veterinarian and founder of Ask A Vet 🩺🐾

Birds can suffer from a range of skin infections—from superficial bacterial dermatitis to viral pox and parasitic mite infestations. This comprehensive 2025 guide will help you:

• 🧫 Recognize bacterial vs fungal vs parasitic vs viral skin issues
• 🔍 Identify conditions like bumblefoot, PBFD, pox, mites
• 💊 Understand diagnostics and treatments
• 🛡️ Learn prevention strategies in home and aviary settings
• 📱 Know when to contact your avian vet via Ask A Vet

Let’s explore common dermal diseases affecting our feathered companions.

1. 🦠 Bacterial Skin Infections & Bumblefoot

Bacterial infections—often Staphylococcus, Streptococcus, Pseudomonas—occur in wounds, feather follicles or pressure points like feet (“bumblefoot”) :contentReference[oaicite:2]{index=2}.

1.1 Bumblefoot (Pododermatitis)

• Common in large or overweight birds, especially raptors, poultry, waterfowl :contentReference[oaicite:3]{index=3}.
• Presents with swelling, scabs, pus on foot pads; leads to lameness.

1.2 Diagnosis & Treatment

• Exam and cultures; imaging to rule out deeper abscesses.
• Warm compresses, soak with Epsom salts, topical antiseptics.
• Oral or injected antibiotics like Baytril (enrofloxacin) guided by sensitivity :contentReference[oaicite:4]{index=4}.
• Debridement of lesions in severe cases, veterinary care essential.

2. 🍄 Fungal & Yeast Skin Infections

Fungal infections in birds include dermatophytes (ringworm), Malassezia, Cryptococcus, Candida, aspergillus and others :contentReference[oaicite:5]{index=5}.

2.1 Signs

• Patchy feather loss, crusts, scaly skin—especially around beak, wing folds :contentReference[oaicite:6]{index=6}.
• In Candida: white marks in crop or featherless areas.

2.2 Diagnosis

• Skin/feather cytology, fungal cultures, histopathology.

2.3 Treatment

• Topical sprays (chlorhexidine) or medicated dips.
• Systemic antifungals: nystatin, fluconazole, itraconazole, clotrimazole, amphotericin B per bird's size :contentReference[oaicite:7]{index=7}.
• Dosage example: nystatin 300,000 IU/kg PO twice daily; fluconazole 20 mg/kg every 48h :contentReference[oaicite:8]{index=8}.

3. 🐛 Parasitic Mites & Dermatitis

3.1 Burrowing Mites – Scaly Leg/Face (Knemidocoptiasis)

Mites like Knemidocoptes burrow into skin causing thick, scaly lesions on legs, face (“scaly leg/face”) :contentReference[oaicite:9]{index=9}.

• Signs: crusty, thickened skin; discomfort.
• Treat with topical or systemic ivermectin under vet guidance.
• Clean cage and isolate affected birds.

3.2 Non-Burrowing Mites – Dermanyssus, Bird Mite Dermatitis

Bird mites can bite both birds and humans causing dermatitis (gamasoidosis) :contentReference[oaicite:10]{index=10}.

• Signs: feather disturbance, irritated skin; in humans: red itchy bites.
• Treat birds with ivermectin; treat environment—vacuum, heat wash, pesticides :contentReference[oaicite:11]{index=11}.

4. 🦠 Viral Skin Diseases

4.1 Fowl Pox (Avipoxvirus)

Cutaneous pox causes wart-like lesions on unfeathered skin; diphtheritic pox affects respiratory mucosa :contentReference[oaicite:12]{index=12}.

• Scabs and pustules on face, feet; respiratory distress if respiratory form.
• Supportive care: iodine dressings, antibiotics for secondary infections; vaccines exist for poultry, canaries :contentReference[oaicite:13]{index=13}.

4.2 Psittacine Beak & Feather Disease (PBFD)

Caused by circovirus, leads to feather follicle and beak damage; skin may scar, thicken and become susceptible to infections :contentReference[oaicite:14]{index=14}.

• Signs: malformed feathers, scaly skin, immunosuppression.
• Diagnose via blood, feather or PCR testing.
• No cure—supportive care, isolation, hygiene, thermal support :contentReference[oaicite:15]{index=15}.

5. 🩺 Diagnosis & When to Call the Vet

• Observe lesion type, location, systemic signs.
• Take samples: skin scrapings, cultures, biopsies.
• Bloodwork to assess overall health.
• Contact your avian vet via Ask A Vet for guidance.

6. 🛡️ Prevention & Environmental Care

• Keep cages clean and dry; disinfect regularly.
• Use sterile substrates; remove worn perches/toys.
• Quarantine new birds; treat flocks simultaneously for parasites.
• Maintain proper nutrition and reduce stress.
• Use vaccines where available (e.g. fowl pox in flocks).
• Control mites and pests around enclosures.

7. 📱 Treatment & Care Tools

• Ask A Vet app: fast consults for lesion pictures, medication recommendations, dosing advice.
• Woopf perches: help prevent pressure sores and foot infections.
• Purrz enrichment: reducing stress aids skin health.

8. 🧠 Summary Table

*Vaccine available only for certain poultry or small birds.

9. 🧡 Final Takeaways

• Skin infections in birds have bacterial, fungal, parasitic or viral origins.
• Accurate diagnosis is essential—don't rely on guessing.
• Treatment ranges from antibiotics and antifungals to ivermectin and supportive care.
• Prevention via hygiene, proper nutrition, environmental management, quarantine.
• Use Ask A Vet app for expert guidance and timely care.

Skin health is a window to your bird's overall well-being. When in doubt, act early—schedule a consult through Ask A Vet or visit AskAVet.com for expert advice. 🐾
