Poultry can also become infected with two kinds of leukosis, infectious laryngotracheitis, turkey rhinotracheitis, chlamdyiosis and various mycoplasma infections. Some other diseases affecting poultry include avian encephalomyelitis, aspergillosis and infectious bursal disease.
A University of Florida Institute of Food and Agricultural Sciences Extension service article divides poultry diseases into three main categories. They are the 16 viral and bacterial respiratory diseases, eight non-respiratory viral diseases and seven non-respiratory bacterial diseases. Some of these diseases have sub-types, and some affect only certain types of fowl. The turkey vulture, for example, is the only species not subject to infection by botulism. On the other hand, the two types of bronchitis affect only chickens and bobwhite quail.
The University of Florida IFAS Extension page gives clinical signs of the diseases, treatment if any is available and prevention measures. The page also lists which diseases can infect which species of poultry.Learn more about Chickens
