Clamydia psittaci is also called Psittacosis, chlamydiosis or parrot fever. These bacteria are related to the Chlamydia trachomatis bacteria. These bacteria cause respiratory infection among birds along with ocular discharge and diarrhea. In some cases the birds may not show signs of infection. The zoonotic potential of this organism can result in transmission of these bacteria from the animals to human beings.

The transmission of these bacteria occurs through air when the bacteria are shed from infected birds through nasal and ocular shedding or through fecal material along with feather dust. This organism can remain stable and becomes dry. It then contaminates the air and is inhaled by another host. Transmission of Chlamydia psittaci from birds to human beings can occur and this is particularly dangerous for individuals who are elderly, sick and pregnant women.

Chlamydia psittaci in birds results in symptoms such as temperature, tremor, yellow or green droppings and lethargy. Among human beings the symptoms associated with this bacterial infection include fever, headache, chills, shortness of breath, myalgia, conjunctivitis, loss of appetite and malaise. This infection can be avoided by preventing this organism from entering the facility.

This infection may spread in bird fares and bird marts and so it is advisable to avoid situations and places where the infection may spread. Following hygienic practices by removing fecal material and improving the air circulation can help in preventing this infection. The symptoms are observed in around 4 to 15 days following an exposure. While psittacosis results in lung disease it can also affect other organs. Diagnosis of this infection can be done through some laboratory examinations.

Treatment for Chlamydia psittaci bacteria includes taking antibiotics like tetracycline and derivatives. The treatment should be continued for a period of around 45 days and the antibiotics should be taken through intramuscular injections or can be administered intravenously. Transmission of this disease from one person to another is quite rare.

For correct diagnosis of this condition it is important to notify the doctor that the concerned patient has come in contact with birds that may be infected with the Chlamydia psittaci bacteria. Through some laboratory examinations the organisms can be detected and the infection can be identified. While the disease can respond well to tetracycline it tends to be resistant to penicillin.
