Isolation and Identification of a Nephrotropic BF Strain of Infectious Bronchitis Virus 鸡传染性支气管炎嗜肾性BF株病毒的分离与鉴定
Since then, extensive surveys in Asia and Europe have revealed many new serotypes of IBV. Recent year, IBV isolates exhibit tropisms for the kidneys in China, and the major IBV isolates are variant nephrotropic strains, which make it very difficult to vaccination. 此后,在亚洲和欧洲也发现了多个新的IBV血清型。近年来,我国IBV分离株大多为肾变型,主要分离株为肾型变异株,给免疫防控带来了很大困难。
