Why do I have to send swabs for psittacosis tests?

The bacterium that causes psittacosis in birds (Chlamydophila psittaci) can be hosted in some individuals without expressing any of the three characteristic symptoms of psittacosis (respiratory diseases, oculibvar / nasal problems and/or diarrhea). To ensure the early detection of the parasite, we request sewage and/or mouth swabs as it is in these places where the bacteria will first be detected.
