👉 Argyrophylax is a type of bacterial infection characterized by swelling in the lungs, typically due to inflammation and damage from infections such as tuberculosis or pneumonia. It can be caused by multiple factors, including bacteria like Streptococcus pyogenes, which are commonly found in the respiratory tract. Argyrophylax occurs when the immune system is unable to effectively fight off the infection, leading to swelling and inflammation of the lungs.
