Pneumocystis jiroveci is what type of pathogen, and what infection does the pathogen cause?

Pneumocystis jirovecii is a fungus, and it causes Pneumocystis pneumonia. It’s an opportunistic pathogen, meaning it typically causes disease in people with weakened immune systems (like AIDS patients or those on immunosuppressive therapy). The infection presents as a subacute, diffuse interstitial pneumonia with symptoms such as progressive shortness of breath, dry cough, and fever, and imaging often shows bilateral interstitial infiltrates. This distinguishes it from bacterial tuberculosis or viral infections like influenza, and from bronchitis, which are not caused by this fungus.
