Hypothesis
Can equine herpesvirus 9 infect and cause disease in species other than equids?
Conclusion
Equine herpesvirus 9 can naturally infect and cause encephalitis in polar bears and has been found in multiple equid species.
Supporting Evidence
- EHV-9 was found in a polar bear with encephalitis and traced back to Grevy's zebras.
- Previous reports indicated EHV-9 infection in Thomson's gazelles and a giraffe.
- Seroconversion was detected in 60% of wild Burchell's zebras without illness.
- Active infection was confirmed in Grevy's zebras and an aborted Persian onager.
Takeaway
Scientists found a virus that can make polar bears sick, and it can also be found in zebras and other animals.
Methodology
The study involved PCR testing of samples from infected animals to identify the virus and its strain.
Limitations
The study did not investigate latency and viral shedding in domestic horses.
Participant Demographics
The study involved a polar bear, Grevy's zebras, and a Persian onager.
