| gene detection, virus isolation, and sequence analysis of avian leukosis viruses in taiwan country chickens. | avian leukosis virus (alv) infection in taiwan country chickens (tccs) was investigated by using gene detection, virus isolation, and sequence analysis. the blood samples of 61 tcc flocks at market ages from a slaughter house were screened for exogenous alvs using polymerase chain reaction to investigate the alv infection status. the buffy coats from three breeder and four commercial chicken flocks were cocultured with df-1 cells to isolate the virus. the full proviral dna genomes of two alv iso ... | 2013 | 24689170 |
