Effect of altered environmental temperature on established infection
1University of New England, Armidale, New South Wales.
Environmental temperature changes significantly impact survival rates in mice with severe bacterial infections like E. coli and S. aureus. This suggests room temperature may affect patient recovery from serious infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Environmental Health
Background:
- Severe bacterial infections, including those caused by Escherichia coli and Staphylococcus aureus, pose significant health risks.
- Many patients with severe infections are treated in environments lacking climate control, such as non-air-conditioned wards.
- The impact of environmental temperature on infection outcomes is not fully understood.
Purpose of the Study:
- To investigate the effect of environmental temperature alterations on mortality rates in a mouse model of severe bacterial infection.
- To explore the potential influence of ambient temperature on the recovery of patients with severe infections.
Main Methods:
- Mice were experimentally infected with severe strains of Escherichia coli and Staphylococcus aureus.
- Environmental temperatures were systematically altered to assess their impact on infection-induced mortality.
- Mortality data was collected and analyzed in relation to temperature variations.
Main Results:
- A ten-degree Celsius change in environmental temperature significantly altered mortality rates in mice with established Escherichia coli and Staphylococcus aureus infections.
- The study demonstrated a clear correlation between ambient temperature and survival outcomes in the infected mouse model.
Conclusions:
- Environmental temperature is a critical factor influencing the severity and outcome of severe bacterial infections.
- Findings suggest that even moderate temperature fluctuations may impact the recovery of human patients with severe infections, highlighting the importance of climate control in healthcare settings.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
