title: New strain multidrug resistant tuberculosis G24767 in Puerto Rico: Old disease a continuous threat.
abstract: Multidrug resistant tuberculosis (MDR-TB) is defined as a Mycobacterium tuberculosis strain resistant to two or more first-line anti-tuberculous drugs. Tuberculosis (TB) is a global threat to society despite improvement in therapy as it continues to be an economic burden especially in underdeveloped countries. The downfall of global economics and growing travel destinations in developing countries has escalade the exposure of organism not previously encountered in industrialized nations. Most cases of MDR-TB are reported on immunosuppressed patients with risk factors and from endemic areas. Nevertheless new strains with higher transmission degree are emerging as a threat in patients who have low risk factors for the development of MDR-TB.
