What is Mycoplasma?
Mycoplasma gallisepticum can cause respiratory disease in chickens. Sneezing, discharge or noisy breathing may have other causes too, so symptoms alone do not establish a diagnosis. A poultry-experienced veterinarian may recommend examination and testing.
How can it spread?
Infected birds can carry the organism without obvious signs. Introducing birds, close contact and contaminated equipment can spread infection. Discuss quarantine and the source flock’s health history before mixing new arrivals.
Signs to watch for
Look for persistent sneezing, watery or swollen eyes, nasal discharge, unusual breathing sounds, reduced appetite or a withdrawn posture. Breathing difficulty or rapid deterioration needs urgent veterinary advice. Record how many birds are affected and when signs began.
Veterinary treatment
A veterinarian decides whether medication is needed and which treatment is suitable. Antimicrobials can reduce signs without eliminating infection or carrier birds. Follow the prescribed course and withholding instructions; do not choose an antibiotic, dose or route from a general website.
Support during recovery
Provide appropriate shelter, clean water and the normal balanced ration within easy reach. Reduce stressful handling and seek advice about safely separating affected birds. Tonics, vitamins, herbs and vinegar do not replace diagnosis or treatment.
Giving prescribed medicines safely
Ask the prescribing vet to demonstrate any administration technique. Giving fluids into a beak incorrectly can cause aspiration. Do not remove access to drinking water or change a prescribed medicine’s route unless the vet instructs you to do so.
Preventing further problems
Use clean equipment, suitable ventilation, sensible stocking and a veterinary quarantine plan. Discuss the implications of carrier birds for new introductions and breeding. Do not assume that a symptom-free hen cannot transmit infection.
When to call the vet
Contact a poultry-experienced vet promptly for respiratory signs. Severe breathing difficulty, collapse or inability to drink requires urgent care. Unusual sickness or deaths affecting several birds also require official animal-health advice.
Using our health checker
The Chicken Hatchery Australia health checker links observations to useful reading. It cannot diagnose Mycoplasma or rule out another disease. Use it to prepare notes for your veterinarian, not to postpone professional assessment.
