Chlamydophila psittaci is a type of bacteria that primarily infects birds, especially parrots, but can also affect other animals and humans. It causes a disease known as psittacosis, which can lead to respiratory issues and other health problems in infected individuals. The bacteria are often transmitted through inhalation of contaminated dust or direct contact with infected birds. In humans, symptoms of psittacosis can include fever, chills, headache, and cough. Diagnosis typically involves blood tests or cultures to identify the bacteria. Treatment usually consists of antibiotics, and early intervention is important to prevent complications.
