Construction and development of new rabiesvirus vectors carrying enhanced greenfluorescent protein: supplementary data

Aim: Rabies is one of the most lethal viral diseases. This study developed a recombinant rabies virus,
PVEGFP, expressing an EGFP protein based on PV strain to be applied in virus-neutralizing antibody (VNA)
titration methods. Methods: The EGFP gene was inserted into the PVMCS strain, a previously discussed
recombinant virus. The recombinant virus was applied in the rapid fluorescent focus inhibition test (RFFIT)
VNA titration method, and six vaccinated persons were studied for validation. Results: The recombinant
rabies strain showed similar propagation properties to its ancestry strain, PVMCS. It could also measure
VNA titers in the RFFIT method not significantly different from those acquired using the CVS-11 virus.
Conclusion: Utilizing the PVEGFP strain in the RFFIT method can produce rapid, reliable and affordable
results.
