a positive respiratory specimen or Acid Fast Bacillus (AFB) smear showing the presence of mycobacterium tuberculosis. The inflammatory response is our body’s way to fight bacterial infection. The immune response is the body’s defense against viruses. Our body's defense system discerns the type of enemy trying to invade, and launches the appropriate response, be it inflammatory or an immune response. Tuberculosis is considered the world’s deadliest disease. Tuberculosis is better known as TB

important to minimise cross infection of Micro-organisms. Many micro-organisms are good for us and are essential for life, such as bacteria in the intestine which helps break down food waste matter. However, when a micro-organism is capable of doing harm it is said to be pathogenic. There are four main micro -organisms that cause disease, these include, Viruses, Bacteria, Fungi, and Protozoa. Personal Protective Equipment (P.P.E) can act as a barrier to protect you against infectious material. P.P

an experiment to see which household products are most effective on the killing of bacteria Micrococcus luteus. The genus of the bacteria being used in this experiment is Micrococcus.
