Summary
Chilling rabbits accustomed to heat increases snuffles risk. Temperature changes, especially from low to high, predispose rabbits to this respiratory infection.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Animal Health
Background:
- Respiratory infections like snuffles are common in rabbits.
- Environmental factors can influence disease susceptibility in animals.
- Previous research on respiratory infections in rabbits has limitations.
Purpose of the Study:
- To investigate the role of temperature changes in rabbit respiratory infections.
- To determine if chilling or temperature fluctuations predispose rabbits to Bacillus bovisepticus.
- To assess the applicability of rabbit snuffles research to human respiratory conditions.
Main Methods:
- Rabbits accustomed to specific temperatures were subjected to chilling.
- Experimental groups experienced temperature changes (high to low, low to high).
- Infection incidence and severity were monitored post-exposure.
Main Results:
- Chilling rabbits accustomed to heat increased the incidence of Bacillus bovisepticus infection.
- Marked temperature changes, particularly from low to high, predisposed rabbits to infection.
- The severity of the respiratory disease correlated with the magnitude of temperature change.
Conclusions:
- Exposure to cold, especially after acclimatization to heat, is a significant factor in rabbit snuffles.
- Temperature fluctuations, with a notable effect from low to high shifts, play a role in respiratory disease susceptibility.
- Findings suggest environmental temperature changes are critical for managing and preventing respiratory infections in rabbits.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
