infectious coryza<\/span><\/b>, which is also referred to as a cold or roup, is caused by the bacterium\u00a0<\/span>haemophilus paragallinarum<\/em>. this disease primarily affects chickens, but quail and pheasants may also be affected.<\/span><\/p>\r\n\r\n\r\n\r\n

coryza is primarily transmitted by direct bird-to-bird contact. in addition, birds can also catch the disease by breathing airborne bacteria and consuming contaminated feed and\/or water. the disease can also be introduced when infected birds are brought into the flock. birds that have recovered from the disease remain carriers of the organism and may occasionally shed the bacteria during their lives. birds risk exposure at poultry shows, bird swaps, and live-bird sales. outbreaks commonly result when infected birds that are not showing any signs of the illness are brought into a healthy flock.<\/span><\/p>\r\n\r\n\r\n\r\n
