Pathogen Chlamydia psittaci is the primary pathogen responsible for psittacosis, commonly known as parrot fever. This bacterium is not highly resistant to heat and is inactivated at 55°C within 5 minutes or at 37°C after 48 hours. Under direct sunlight, it can survive for up to 6 days, and in water, it may remain viable for up to 17 days. While Chlamydia is relatively insensitive to acidic and alkaline environments, it is easily destroyed by quaternary ammonium compounds and lipid solvents. Common disinfectants such as benzalkonium chloride, iodine solutions, 70% alcohol, and 3% hydrogen peroxide can effectively reduce its infectivity within minutes. Epidemiology Chlamydia psittaci affects a wide range of bird species, with parrots and pigeons being particularly susceptible. Infected birds and asymptomatic carriers are the main sources of transmission. The disease spreads through airborne particles, such as dust and droplets, entering the respiratory tract or eyes. Insects like cockroaches that feed on blood can also contribute to the spread. Humans can contract the infection, so proper hygiene and protective measures are essential when handling birds or cleaning their habitats. Symptoms The clinical signs of Chlamydia psittaci infection vary depending on the strain's virulence. Parrots and pigeons may show different symptoms. Infected parrots often appear lethargic, lose their appetite, and develop purulent discharge from the eyes and nose. As the disease progresses, they may suffer from diarrhea, dehydration, and significant weight loss. Pigeons typically display restlessness, eye and nasal secretions, loss of appetite, and diarrhea. Most older pigeons recover but may become long-term carriers of the bacteria. Prevention 1. Control the source of infection: Before introducing new birds into an existing group, ensure that the area is free from Chlamydia. It is recommended to isolate new birds for at least two weeks and monitor them closely during this period. 2. Proper disposal of feces, litter, and feathers is crucial. All cage equipment should be thoroughly disinfected, and measures should be taken to eliminate blood-sucking insects to prevent disease spread. 3. Tetracycline antibiotics, including chlortetracycline, oxytetracycline, and erythromycin, are effective treatments. However, chloramphenicol should be avoided due to its toxicity. The typical dosage is 2–4 grams per kilogram of feed, though it may not work for latent infections. Treatment should be conducted under strict isolation conditions. If the number of infected birds is small, culling may be considered. 4. Administer "Bird Music" for 5 to 7 days, with a daily dose of 1 gram. 5. Feeding "Enhanced" No. 6 capsules is also recommended for better results.
