Common poultry diseases include Aspergillosis, avian influenza and botulism. Aspergillosis is an infectious fungal disease that is not contagious. It primarily affects the respiratory tract of poultry, but can affect all organs.Continue Reading
It is most often found in chickens and turkeys, and less frequently in ducks, geese, pigeons, canaries and other wild or pet birds. Aspergillosis may cause acute and chronic infection and usually appears in birds that are 7 to 40 days old. It is believed to be caused by impaired immunity and the inhalation of large numbers of spores that have been contaminated.
Avian influenza, or bird flu, is spread through the secretions of infected birds and is caused by the H5N1 virus. Mosquitoes and ticks may also transmit avian flu, with outbreaks often coinciding with the rainy season where mosquitoes are abundant. Avian flu is transmittable to people, and as of 2004, all known cases have appeared in Southeast Asia, contracted by people who handle chickens. Infected birds shed the virus in their saliva, droppings and nasal secretions. As of 2015, the Centers for Disease Control considers the risk of transmission to people as low.
Botulism occurs in poultry as a result of ingesting the toxin Clostridium botulinum, a bacteria that is widespread in soil. Decomposing vegetation, coupled with warm temperatures, provides an ideal environment for botulism to occur. Botulism often causes death in waterfowl, with ducks most often affected.Learn more about Chickens
