Aspergillosis is a non-contagious respiratory disease caused by a fungal species known as Aspergillus. Commonly referred to as mycotic pneumonia, brooders pneumonia, or fungal pneumonia, Aspergillosis affects chickens, ducks, turkeys, waterfowl, game birds, and many other bird species.
Young birds are the most susceptible to infection, though older birds under stress or with compromised immune systems can develop chronic Aspergillosis.
Infection with Aspergillosis occurs through the inhalation of spores, typically from contaminated litter or other contaminations in the hatchery. Infection in young chicks is usually the result of inhaled spores from a contaminated hatching machine. Infections can also occur when infected eggs hatch during incubation and release large numbers of spores which are inhaled by other chicks.
Incidence and severity of the disease increases under warm, wet, or humid conditions. Dusty conditions and environments that result in high levels of ammonia are also perfect breeding grounds for Aspergillosis. That’s why contaminated poultry bedding is one of the most common sources of infection. Continue reading “What is Aspergillosis? Plus How to Prevent It in Your Flock”
