What is the primary route for *A. paragallinarum* transmission between chickens in a commercial flock?

Answer

Direct contact involving the inhalation of aerosols or droplets.

Infectious Coryza is known for spreading extremely rapidly through a susceptible population, primarily due to its highly contagious nature. The dominant and most efficient method by which the causative bacteria moves from an infected bird to a healthy one is direct contact. This occurs when susceptible birds inhale respiratory particles, such as aerosols or droplets, that are forcefully expelled by an infected individual through coughing or sneezing. While indirect routes involving fomites and personnel are significant contributors to introducing the disease or spreading it between different farm areas, direct aerosol transmission within the immediate flock remains the principal mechanism for rapid spread among birds.
