Purpose: Chronic granulomatous disease (CGD) is an inherited immunodeficiency caused by pathogenic variants of genes encoding the enzyme complex NADPH oxidase. In countries where tuberculosis (TB) is endemic and the Bacillus Calmette-Guérin (BCG) vaccine is routinely administered, mycobacteria are major disease-causing pathogens in CGD. However, information on the clinical evolution and treatment of mycobacterial diseases in patients with CGD is limited.

Based on phylogeny, clinical symptoms, and antigenic properties, rickettsiae are classified into four groups. Infections by these agents are characterized by clinical symptoms ranging from self-limited to severe and even fatal febrile illnesses, depending on the Rickettsia spp.

Introduction: Chronic granulomatous disease (CGD) is an inborn error of immunity, characterized by abnormal susceptibility to bacterial and fungal infections and a lack of systemic inflammatory regulation. Pathogenic variants in the CYBB gene are transmitted in an X-linked pattern of inheritance; while the pathogenic variants present in the EROS, NCF1, NCF2, NCF4, or CYBA genes are transmitted with an autosomal recessive inheritance pattern.
Objetives: To describe the clinical, immunological, and genetic characteristics of two patients with CGD and BCG infection.
