Streptococcus pneumoniae (pneumococcus) has long been one of the most prominent bacterial causes of disease in humans and was one of the first to be identified as a cause of human infection [ 1 ]. Since 2000, however, its impact has been blunted by the widespread use of vaccines that largely prevent infection and colonization in young children.

Some pneumococcal infections are considered “invasive” when the infection occurs in areas parts of the body that are normally sterile.Staphylococcus epidermidis is a round, gram-positive, catalase-positive, coagulase-negative, and urease-positive bacteria, which is normally part of the normal human flora, especially on the skin and mucosa. While S. epidermidis is generally harmless, it can cause opportunistic infections in people with weakened immune systems. Streptococcus pneumoniae (the pneumoccus) is the leading cause of otitis media, community-acquired pneumonia, and bacterial meningitis. The success of the pneumococcus stems from its ability to persist in the population as a commensal and avoid killing by immune system.
