In this system, PI3 virus enhances the pathogenicity of P. haemolytica and we have shown this interaction occurs with several serotypes of P. haemolytica. Davies and his co-workers have also shown this effect, but apparently without clinical illness. Unfortunately, these authors did not refer to the serotype of P. haemolytica which was used in their experiments nor describe the type of pneumonic lesions that were induced…
