Improving Rabies Animal Models for Medical Countermeasures through Luminescent Animal Models
- CDC scientists work to develop and test new medical countermeasures (MCMs) that can be used to protect the public from diseases in the event of an outbreak, natural disaster, or bioterrorism event. MCMs can include things like vaccines, medications, and diagnostic tests. Research on MCMs can include using animal models to test their effectiveness. Some pathogens, like Rabies lyssavirus (RABV), cause few signs of infection before death, which makes it hard to know if test animals survive because of effective MCM treatment, or because they were never infected.
- We tested two RABV strains that had genes added to produce light when the viruses spread in infected animals. We found that these light-producing, or luminescent, rabies strains showed clear evidence of infection in mice, measured in “radiance” using a special laboratory imager. This meant we could detect rabies infection in living animals before clinical signs of rabies were detected.
- Luminescent rabies strains give clear and early signs of rabies virus in test animals. These new models could reduce the number of animals needed for testing, limit harm to test animals, and lower project times as we work to develop and improve MCMs for rabies.
“Medical countermeasures, or MCMs, are a crucial part of public health readiness in the event of an emergency. Improving our animal models will allow future MCM research to be more targeted and efficient, and can reduce the use of laboratory animals in the development and testing of MCMs”
