Since 1995, a new disease characterized by stunted growth, the provenventriculus swelling, the proventricular papilla hemorrhage and ulcer had been found in some regions of China.

自1995年以来，我国一些地区相继发生了一种以鸡体慢性消瘦，腺胃严重肿大，腺胃乳头出血、溃疡为特征的疾病，给养鸡业造成了巨大损失。

Three infectious bronchitis virus isolates named as Q1, J2 and T3 were isolated from proventricular tissue taken from vaccinated chicken flocks in China.

从我国接种过传染性支气管炎疫苗的幼鸡群的腺胃组织中分离得到三个传染性支气管炎毒株Q1、J2和T3，并对它们的部分生物学特性进行研究。

According to epidemiological investigation, the occurance of the disease was related with breeding chickens, in which the IBV had played and important role in the infected chickens. The histopathological and ultrastructural lesions in proventricular, bursa of Febrcius, thymus, duodenum and kidney were studied.

流行病学调查表明：本病的发生与种鸡场有关，IBV在本病的发生过程中起到重要的作用，根据本病突出的病理变化为腺胃炎，我们将其称作传染性腺胃炎。

Four viral strains were found in proventricular tissues; three of them were identified as reticuloendotheliosis virus, coronavirus and Newcastle disease virus respectively. 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。
