Effect of pH on the growth and cytopathogenicity of avian infectious bronchitis virus in chick kidney cells

摘要

The growth of avian infectious bronchitis virus (IBV) in chick kidney cells at different pH values in the range 6.0–9.0 demonstrated that although the virus was released at a much faster rate at the higher pH values the titre tended to drop more quickly. At the acid pH values the virus was released more slowly but reached a maximum titre similar to that at the higher pH values and showed only minimum reduction in infectivity up to 49 hours post inoculation.
