Non-Human Primate Models of Tuberculosis

Among the animal models of tuberculosis (TB), the non-human primates, particularly rhesus macaques (Macaca fascicularis) and cynomolgus macaques (Macaca mulatta), share the greatest anatomical and physiological similarities with humans. Macaques are highly susceptible to Mycobacterium tuberculosis infection and manifest the complete spectrum of clinical and pathological manifestations of TB as seen in humans. Therefore, the macaque models have been used extensively for investigating the pathogenesis of M. tuberculosis infection and for preclinical testing of drugs and vaccines against TB. This review focuses on published major studies that exemplify how the rhesus and cynomolgus macaques have enhanced and may continue to advance global efforts in TB research.
