Two males with acute bronchiolitis due to <I>Mycoplasma (M.) pneumoniae</I>, aged 24 and 39 years were reported. They presented prolonged cough and fever in the early stage of the disease. Chest Xrays of those patients showed diffused nodular shadows. Chest CT scan showed diffused nodular shadows and thicknning of bronchovascular marking. Blood-gas analysis indicated hypoxemia without abnormal A-aDO<I>2</I>. We diagnosed two patients as <I>M. pneumoniae</I> infection by antibody assays. The Eosinophil cationic protein (ECP) level and IgE level were high. Eosinophilia and endotoxemia were also observed in two patients. We speculated that the allergic reaction and endotoxemia may be related to hypoxemia and the clinical severity of <I>M. pneumoniae</I> infection.
