Abstract

Eighteen isolates of infectious bronchitis virus (IBV) from Italy and Poland in 1997 to 1998 were comprehensively analysed by serum haemagglutination inhibition and virus neutralization tests, and by type-specific polymerase chain reactions and spike protein S1 gene sequencing. Four types of IBV (793/B, 624/I, B1648 and Massachusetts) were detected in Italy, while the presence of 793/B was confirmed in Poland. This showed that not only were four types of IBV co-existing within a single year, but also that several types of IBV have persisted in Europe for many years (at least 13 to 14 years for types B1648 and 793/B). Sequencing of the S1 gene of the 624/I isolate confirmed this as a unique type of IBV.

摘要

1997年至1998年期间，从意大利和波兰采集了18株传染性支气管炎病毒（IBV）分离株，通过血清血凝抑制试验、病毒中和试验、型特异性聚合酶链反应以及刺突蛋白S1基因测序进行了全面分析。在意大利检测到了四种类型的IBV（793/B、624/I、B1648和马萨诸塞型），而在波兰证实存在793/B型。这表明，不仅在同一年中有四种类型的IBV共存，而且几种类型的IBV已在欧洲持续存在多年（B1648型和793/B型至少已存在13至14年）。对624/I分离株的S1基因进行测序，证实其为一种独特类型的IBV。
