Progression of infection
An infection is the invasion of the body microorganisms with pathogenic abilities such as bacteria, parasites and Viruses. Pathogens (Bacteria) invade the host cells, multiply greatly and secrete toxins that cause cellular damage or lysis that trigger an immune response that causes localised inflammation and activation of leukocytes to prevent the spread of pathogens to other areas of the body. Depending on the host’s immune system, sometimes the increase in the number of bacteria overwhelms the immune system causing the infection to spread to other parts of the body (Remick, Pathophysiology of sepsis, 2007). This is commonly attributed to gram positive and gram negative bacteria that usually cause severe infections that lead to an extreme inflammatory and immune response as a lot of cytokines are released as the
