Archives of Virology Aims and scope Submit manuscript

Summary

The virulence of influenza A viruses was determined using the intracerebral pathogenicity index test for chickens. The viruses were divided into high virulent, low virulent and avirulent strains. A low virulent strain was recovered from the jejunum and faeces of infected chickens.
