Birds, Humans, Cats, Cattle, Goats, Sheep, and Pigs

Overview / Symptoms

  • Psittacosis is caused by the bacterium Chlamydophila psittaci, which can be found in the droppings of infected birds
  • All birds are susceptible to psittacosis and may transmit it to mammals, including cattle, cats, goats, sheep, pigs, and humans
  • Human cases are rare, but typically result from contact with infected pet birds (parrots, parakeets, macaws, and cockatiels) or poultry (turkeys and ducks)
  • Humans may experience fever, chills, headache, muscle aches, and a dry cough
  • Transmitted to humans through the inhalation of dried secretions from infected birds
  • There are no specific symptoms in infected birds, but some may present with weight loss, depression/listlessness, difficulty breathing, pink eyes that may produce discharge, watery green feces, or sudden death
