Another unidentified virus was of spherical shape, ranging from 60nm to 80nm in diameter, and could be found only among cells.

从腺胃组织的超薄切片中可观察到四种病毒颗粒，分别为IBV、网状内皮组织增生症病毒和新城疫病毒，此外还有一种呈球形，大小在60~80nm的病毒颗粒，该病毒主要分布于细胞间隙中，尚未鉴定。

7Kb of these isolates were amplified by using RT-PCR The amplified DNA were then cloned and sequenced The analysis of the sequence data further confirmed that IBV was the pathogenic agent of the infectious disease associated with proventricular lesion

利用扩增片段两端的EcoRⅠ和BamHⅠ位点将扩增片段克隆进pBluescripⅡKS载体，转化大肠杆菌JM109，挑选白色菌落并用PCR方法对插入片段进行鉴定。用双脱氧终止法对扩增的片段进行测序并与GenBank公开的序列进行比较分析。结果进一步证实IBV是导致此种野外发生的腺胃相关疾病的病原。
