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。

Three infectious bronchitis virus isolates named as Q1, J2 and T3 were isolated from proventricular tissue taken from vaccinated chicken flocks in China The biological characteristics of the three isolates were observed.

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。将病毒通过9-11日龄鸡胚，盲传5-6代。

In clean diluent condition, the median lethal concentration (MLC50) of CIO2 against bacteria and yeast was 9.4 and 8.4 ppm, respectively. In dirty diluent condition, the MLC50 of CIO2 against bacteria and yeasts was 39.9 and 24.3 ppm, respectively. The virucidal activity of CIO2 against 100 median embryo lethal dose (100 ELD50) of Newcastle disease virus, avian influenza virus, infectious bronchitis virus and infectious bursal disease virus was 1.2, 1.2, 2.5 and 1.2 ppm, respectively.
