Existence of variant strains fowlpox virus
integrated with reticuloendotheliosis virus in its genome in field isolates in Tanzania.
A recombinant fowlpox virus vaccine expressing key protective Mycoplasma gallisepticum antigens could facilitate in the prevention both of fowlpox virus and M.
Naturally occurring dual infection of layer chickens with fowlpox virus and gallid herpesvirus 1 (infectious laryngotracheitis virus) can be diagnosewith the help of electron microscopy, PCR andhistology (24).
Evaluation of recombinant fowlpox virus
expressing infectious bronchitis virus S1 gene and chicken interferon- gene for immune protection against heterologous strains.
Detection of specific reticuloendotheliosis virus sequence and protein from REV-integrated fowlpox virus strains.
Integration of the reticuloendotheliosis virus envelope gene into the poultry fowlpox virus genome is not universal.
We included both inactivated and recombinant fowlpox virus
expressing H5 (rFPV-H5) vaccine studies that used specific-pathogen-free chickens where outcomes against the H5N1 or H5N2 AI viruses were measured.
Immunization of chickens against IBD using a vector that in vivo expresses VP2 has been previously reported using an avian herpesvirus vector , a fowlpox virus
vector , a fowl adenovirus vector  and a Marek's disease virus vector .
The ELISA or hemagglutination inhibition assay was used to test serum samples (N = 38) for antibodies against avian influenza virus, infectious bursal disease virus, fowlpox virus
, and Newcastle disease virus.
In contrast, chickens in Galapagos were infected with a virus that appears to be identical in sequence to the characterized fowlpox virus
and about 30% different from the canarypox/Galapagos group viruses in the regions sequenced.
Efficacy of nucleoprotein and haemagglutinin antigens expressed in fowlpox virus
as vaccine for influenza in chickens.
