What should be done if mice sneeze? - in detail
When a laboratory or pet mouse begins to sneeze, immediate assessment is required to determine whether the symptom reflects a harmless irritation or a sign of underlying disease.
First, isolate the animal from the main colony. Place it in a clean cage with fresh bedding, limiting contact with other rodents to prevent possible spread of infection. Observe the mouse for additional signs such as nasal discharge, ocular inflammation, lethargy, weight loss, or altered breathing patterns. Record the frequency and intensity of the sneezing episodes.
Second, evaluate environmental factors. Check for dust accumulation in the cage, excessive ammonia levels in the bedding, strong odors, or drafts that could irritate the respiratory tract. Reduce humidity to 40‑60 % and ensure proper ventilation. Replace contaminated bedding with low‑dust, absorbent material and clean all accessories with a mild disinfectant that is safe for rodents.
Third, review the animal’s diet and health history. Introduce a high‑quality protein source and provide fresh water. Eliminate any recent changes in food formulation that might contain allergens or irritants. If the mouse has been exposed to pathogens, consult the colony’s health monitoring records for recent outbreaks of murine respiratory viruses or Mycoplasma spp.
Fourth, seek professional veterinary assistance. A qualified veterinarian can perform a physical examination, collect nasal swabs, and order diagnostic tests such as PCR, culture, or radiography. Treatment may involve antibiotics for bacterial infections, antiviral medication for specific viral agents, or supportive care including humidified chambers and anti‑inflammatory drugs.
Finally, implement preventive measures. Regularly clean cages, replace bedding, and monitor air quality. Maintain quarantine protocols for new arrivals and conduct routine health screenings. Document any respiratory incidents in a log to identify patterns and adjust husbandry practices accordingly.
