Recombinant canarypox virus expressing the VP2 protein of infectious bursal disease virus induces protection in vaccinated SPF chickens
To study the in vivo distribution of the CNPV viral vector, we conducted two trials. In the first trial, six 11- day-old SPF chickens were intramuscularly vaccinated in one leg with CN048-VP2 (106 plaque-forming units (PFU) mixed with 0.5% v/v Indian ink). Three birds were sacrificed at 1 and 3 days after vaccination, and muscle at the immunization site (identified by Indian ink), muscle from the non-injected leg, BF, and spleen were removed, weighed, and homogenized in phosphate buffer (50% w/v). Total DNA was extracted from organs using a QIAamp® DNA Mini Kit (QIAGEN, USA) and used as the template for PCR amplification of CNPV241 (primers P39F: 5′-AATAACACGACACAGCCGCAAG-3′, P39R: 5′-CAATTAATTAGATCGTGGTGGA-3′) or the glyceraldehyde-3-phosphate dehydrogenase (gapdh) gene (primers GAPDH Fw: 5′-AGAACATCATCCCAGCGTCC-3′, GAPDH Rv: 5′-CGGCAGGTCAGGTCAACA-3′).
