Some of the members of the Mycobacterium avium-intracellulare (MAI) complex are recognised as human pathogens in both immunocompromised and immunocompetent patients. The current molecular methods that are available to genotype the MAI complex members can be both expensive and technically demanding. In this report, we describe for the first time the application of a real-time PCR and high resolution melt approach to differentiate between the complex members by targeting a member of the PPE (Pro-Pro-Glu) gene family, MACPPE24. In this aim, reference strains of the Mycobacterium avium subspecies and Mycobacterium intracellulare (M. intracellulare) were used to optimise the technique. Then, this real time PCR-HRM approach was used to distinguish 10 Mycobacterium avium subspecies hominissuis field isolates from the M. intracellulare reference strain
