| Abstract: | Twenty-seven Australian avian Haemophilus isolates were tested for their ability to cause infectious coryza in specific pathogen-free chickens. All 15 isolates, identified as H. paragallinarum, produced infectious coryza, whereas all 12 H. avium isolates were nonpathogenic, but spread to in-contact chickens. |
