Researchers from the University of Queensland (UQ) developed a new vaccine against West Nile Virus (WNV) to protect farmed saltwater crocodiles from skin lesions. | ManilaBulletin READ:
According to their study recently published in the npj Vaccines journal, the chimeric virus vaccines are composed of the non-structural genes of the insect-specific flavivirus Binjari virus and genes encoding the structural proteins of WNV.
"We have demonstrated that our vaccine induces a robust immune response in vaccinated animals after two doses," said Hall, adding that "crocodiles that received the vaccine developed strong protective immunity against WNV, without the virus replicating." "Crocs infected with the local strain of WNV, known as Kunjin virus, develop small skin lesions called pix, which renders their hide unsaleable," said Hobson-Peters.
In the eyes of the research team, protecting farmed crocodiles not only holds economic value but also has ecological benefits.
