Psittacosis, a disease affecting birds, is caused by the bacterium Chlamydia psittaci. Typically transmitted through inhalation of contaminated particles from bird droppings or respiratory secretions, it primarily impacts avian species, with parrots being common carriers. Infected birds may exhibit respiratory distress, nasal discharge, and lethargy. The bacterium can persist in the environment, posing a risk to other birds and those in close contact. In many cases, infected birds show no symptoms, complicating early detection. Veterinary care is crucial for diagnosis and treatment, often involving antibiotics. Proper hygiene, quarantine measures, and maintaining a clean environment are essential in preventing the spread of psittacosis among bird populations. Bird owners, breeders, and workers in aviaries or pet shops should be vigilant, as psittacosis can have significant consequences for avian health and welfare.
