ABSTRACT
Hadi T., Residence time
of H9N2 avian influenza virus in lung and kidney of vaccinated broilers, Onl J Vet Res., 28
(12): 853-859, 2024. RT-PCR assay was performed to compare
duration of H9N2 avian influenza virus in lung and kidney of broilers 3, 7, 11
and 15 days after vaccination. Thirty day old
commercial broiler chicken were inoculated intranasaly with H9N2 low pathogenic avian influenza virus.
Five chickens were randomly selected on days 3, 7, 11 and 15 after vaccination
for lung and kidney virus. We found virus in lung ~20% on day 3, 80% day 7, 20%
day 11 and none on day 15 and in kidneys ~20% on day 3, 80% day 7, 20% day 11 and
20% day 15 after vaccination. Results suggest that
H9N2 avian influenza subtype replicates in body of chickens but remains in
kidney longer.
