Tuberculosis (TB) remains a leading cause of death globally among infectious diseases that has killed more numbers of people than any other infectious diseases. Animal models have become the lynchpin for mimicking human infectious diseases. Research on TB could be facilitated by animal challenge models such as the guinea pig, mice, rabbit and non-human primates. No single model presents all aspects of disease pathogenesis due to considerable differences in disease resistance/susceptibility between these models. Availability of a wide range of animal strains, Mycobacterium tuberculosis strains, route of infection and doses affect the disease progression and intervention outcome. Different animal models have contributed significantly to the drug and vaccine development, identification of biomarkers, understanding of TB immunopathogenesis and host genetic influence on infection. In this review, the commonly used animal models in TB research are discussed along with their advantages and limitations.
