Abstract

Abstract Mycoplasma orale is a rare cause of invasive infection in immunodeficient hosts. Phosphatidylinositol 3-kinase, regulatory subunit 1 (PI3KR1) mutations predispose patients to sinopulmonary infections, alongside bronchiectasis autoimmunity and lymphoproliferation. We report 2 cases of PI3KR1 deficiency with invasive M orale and effective treatment options.
