Mycobacterium is a type of bacteria that causes tuberculosis (TB) in humans. When dividing, cells usually split equally while copying DNA from the mother cell to the daughter cell. Recent research has shown that Mycobacteria behave in a unique manner, with cells dividing (through binary fission) asymmetrically. This means that the Mycobacteria all divide differently; they grow at different rates, sizes and have different vulnerability to antibiotics. Because the Mycobacteria cells are all different from one another, it is hard to create drugs that will defeat and kill all the different types of tuberculosis a human has acquired. Although it seems like one could look at this bacteria under a microscope to analyze this basic conclusion, it was not discovered until recently that this actually occurs. This concept is very important to society because . Another discovery that was found was that when the Mycobacterium divide, the newly created daughter cells grow from the mother’s “older” end of the cell. This means as cellular division continues to occur, there will be a variety of Mycobacteria that are different ages. This leads to different growth rates, while also creating a different vulnerability for each M. tuberculosis cell to antibiotics
