易传染

It was not until scientists like Louis Pasteur and Robert Koch developed the germ theory that the mystery of infectious disease was unraveled.

它直到科学家象一样路易斯·帕斯蒂尤尔和罗伯特·科奇开发了细菌理论谜传染的疾病被解开。

The causative agent of the disease is an Corona virus, infectious bronchitis virus IBV）, classified as Corona .Present vaccines for IB are all modified live viruses derived either by sequential passage embrocated chicken eggs. As Immunogenicity of IBV is usually correlated with its virulence, almost all modified live IB vaccines remained insufficient attenuation and have shown a variety of side effects including spread of vaccine virus to no vaccinates, occurrence of long term "carrier" birds, and increasing virulence during in vivo passage.

目前国内外预防本病所用的疫苗大多数是弱毒疫苗，但现用弱毒疫苗都存在以下缺点：（1）与IBV强毒一样，其弱毒疫苗株也能引起潜伏感染，潜伏感染的鸡将终生带毒；（2）疫苗病毒可以由接种鸡传染给非接种鸡，在鸡群之间传播过程中毒力会返强，从而成为新的感染源；（3）传染性支气管炎病毒极易发生变异，且易成为病毒重组的供体和受体，给使用IB传统疫苗预防和根除IB带来极大的困难。

He had commanded him not to come near him during his illness, which was exceedingly contagious: but finding that Castruccio waited on him by stealth, he felt that it was in vain to oppose; and, only intreating him to use every imaginable precaution, they spent the last hours of Ruggieri's life together.
