Introduction The Gram-positive bacterium,Streptococcus pneumoniae(***),often colonizes the nasopharynx;however,it is one of the major microorganisms that cause pneumonia and meningitis.[[1],[2],[3]]It presents several virulence factors,such as surface proteins and enzymes,pneumolysin toxin,and a polysaccharide capsule,which is mainly responsible for the immune response;the capsule also facilitates classification of the bacterium into several serotypes.[1,2]In vulnerable individuals,the bacterium may lead to the development of invasive pneumococcal disease(IPD),which is defined as an infection of normally sterile locations.
