A numerical method for the IBV problems of the nonlinear reaction-diffusion equation was described.
本文讨论了求非线性反应—扩散方程初边值问题数值解的一种方法。
IBV mainly causes damages in respiratory tissue, reproductive system and kidney, and results in decreased both egg production and quality and poor performance.
This paper reports the course followed leading to the successful adaptation of IBV Massachusetts 41 strain to CEK cells as a prerequisite for the development of a micro serum neutralization test.
The protective efficacy of vaccines showed that the live attenuated vaccines only provided partial protection to the vaccinated chickens against heterologous IBV infection.
我国目前使用的主要活疫苗对异种IBV分离株的感染不能提供完全的保护作用。
To study the genomic characteristics of IBV variant isolate, we obtained the full genome sequences of nephropathogenic JH06111 by amplifying, cloning and sequencing of its cDNA.
Our results also showed that invivo recombination of IBV may have occurred at a rather high frequency, contributing to the diversity of these IBV isolates.
