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”).
1.1 Bumblefoot (Pododermatitis)
- Common in large or overweight birds, especially raptors, poultry, waterfowl.
- 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.
- 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.
2.1 Signs
- Patchy feather loss, crusts, scaly skin—especially around beak, wing folds.
- 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.
- Dosage example: nystatin 300,000 IU/kg PO twice daily; fluconazole 20 mg/kg every 48h.
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”).
- 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).
- Signs: feather disturbance, irritated skin; in humans: red itchy bites.
- Treat birds with ivermectin; treat environment—vacuum, heat wash, pesticides.
4. 🦠 Viral Skin Diseases
4.1 Fowl Pox (Avipoxvirus)
Cutaneous pox causes wart-like lesions on unfeathered skin; diphtheritic pox affects respiratory mucosa.
- Scabs and pustules on face, feet; respiratory distress if respiratory form.
- Supportive care: iodine dressings, antibiotics for secondary infections; vaccines exist for poultry, canaries.
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.
- Signs: malformed feathers, scaly skin, immunosuppression.
- Diagnose via blood, feather or PCR testing.
- No cure—supportive care, isolation, hygiene, thermal support.
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.
