Turning to something which is thankfully, far less common
but a little bit cuter would be Chlamydia Psittaci causing Psittacosis or Parrot Fever
such as we see in this beautiful and fascinating image on the screen.
Psittacosis is as I mentioned before, transmitted through dry bird feces,
typically aerosolized to the human recipient when they’re changing the papers
at the bottom of the cage.
Most Psittacosis is asymptomatic thankfully
but it rarely can cause a mild flu-like illness progressing
all the way up to a very serious interstitial pneumonia accompanied by respiratory failure,
so, patients may become cyanotic, have air hunger, breathing difficulties.
If they have underlying chronic lung disease, they may then develop systemic disease
because the lungs have allowed dissemination of the organism into other parts of the body.
Those patients may develop liver failure and jaundice
and they may develop central nervous system involvement including seizures, severe headaches,
and even encephalopathy and coma.
