Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear. The incidence of disease among those infected varies greatly depending on the particular pathogen and individual susceptibility.
Tuberculosis is an infectious disease. The bacteria that cause tuberculosis are called mycobacterium tuberculosis. People with TB or tuberculosis cough excessively and suffer a terrible pain in the chest. They cough up blood and display excessive weight loss, fatigue, loss of appetite, and persistent fever.hile a majority of bacteria in the human body are countered by the immune system, there are a few that are pathogenic in nature. Pathogenic bacteria cause infectious diseases like leprosy, cholera, anthrax, and bubonic plague.
