A case of acute psittacosis with severe abdominal pain.

We report the case of a psittacosis patient with severe abdominal pain who subsequently developed acute respiratory failure. The main symptoms of psittacosis are considered to be upper respiratory inflammation and influenza-like symptoms. However, it should be emphasized that digestive symptoms can be prominent in psittacosis patients. Early diagnosis of this condition is difficult and there is a need for an effective method for rapid diagnosis.
