Hermann's Tortoise Respiratory Infection
Respiratory infections are one of the more serious health issues in Hermann's Tortoises. Unlike some reptile illnesses that develop slowly, respiratory infections can progress quickly and require veterinary treatment. This guide covers the signs to look for, likely causes, and what to do.
Signs of Respiratory Infection
- Wheezing, clicking, or crackling sounds when breathing
- Open-mouth breathing
- Nasal discharge (clear or mucus)
- Lethargy and reduced activity even when warm
- Loss of appetite
- Tilting the head upward to breathe more easily
- Bubbling around the nose or mouth
A tortoise displaying any of these signs — particularly wheezing, open-mouth breathing, or nasal discharge — should be seen by a reptile-experienced veterinarian. Suspected respiratory infections should not be left untreated or simply monitored at home.
Common Causes
- Incorrect temperatures — keeping a tortoise too cool can impair normal activity and immune function; ensure the basking spot reaches 90–95°F
- Excess humidity — persistently damp conditions and inadequate ventilation can contribute to respiratory problems; maintain the recommended humidity range while providing good airflow
- Poor ventilation — stagnant air in enclosed glass terrariums increases respiratory disease risk; tortoise tables with open tops are preferred for this reason
- Stress — chronic stress from an inadequate enclosure suppresses immune function
- Exposure to a sick animal — respiratory pathogens can spread between tortoises; quarantine new animals for a minimum of 60–90 days before introducing them to an existing collection
What to Do
If you suspect a respiratory infection:
- Check and correct temperatures immediately — ensure the basking spot reaches 90–95°F
- Ensure humidity is within the 40–60% range and ventilation is adequate
- Contact a reptile-experienced veterinarian — do not wait to see if symptoms resolve on their own
- Do not introduce the affected animal to other tortoises until cleared by a vet
Treatment typically involves antibiotics prescribed by a veterinarian following examination and, where appropriate, culture and sensitivity testing to identify the causative organism. Do not attempt to treat a respiratory infection with over-the-counter products.
Prevention
- Maintain correct basking and ambient temperatures at all times
- Keep humidity within the 40–60% range; ensure good enclosure ventilation
- Quarantine all new tortoises before introducing them to an existing collection
- Schedule annual veterinary checkups including fecal testing
- Avoid sudden temperature drops, particularly overnight
