One pair of primers was designed and synthesized based on the nucleotide sequence(M64927)of chicken infectious laryngotracheitis virus(ILTV) gB gene pulished in the GenBank. gB gene of ILTV Henan isolate(ILTV-CG) was amplified by PCR.

• 根据传染性喉气管炎病毒(ILTV)gB基因的核苷酸序列；设计、合成1对引物；应用PCR扩增鸡ILTV河南株(ILTV-CG)gB基因.
