Bone and joint tuberculosis

Bone and joint tuberculosis is tuberculosis bacteria that invade the human body through the respiratory tract or digestive tract to form primary foci. Tuberculosis bacteria enter lymphatic blood lines and spread to all organs in the body, especially the reticuloendothelial system including bones and joints. The foci were destroyed by phagocytic cells, and a very small number of spreads were latent early. Once the body's resistance decreased, the tuberculosis bacteria in the latently infected foci multiplied, broke through the surrounding tissues, and became ill.
