text_B: Streptococcus pneumoniae , or pneumococcus , is a Gram-positive , alpha-hemolytic -LRB- under aerobic conditions -RRB- or beta-hemolytic -LRB- under anaerobic conditions -RRB- , facultative anaerobic member of the genus Streptococcus .. Streptococcus. Streptococcus. Gram-positive. Gram-positive. facultative anaerobic. facultative anaerobe. genus. genus. alpha-hemolytic. hemolysis ( microbiology ). As a significant human pathogenic bacterium S. pneumoniae was recognized as a major cause of pneumonia in the late 19th century , and is the subject of many humoral immunity studies .. pathogenic bacterium. pathogenic bacterium. pneumonia. pneumonia. humoral immunity. humoral immunity. S. pneumoniae resides asymptomatically in healthy carriers typically colonizing the respiratory tract , sinuses , and nasal cavity .. nasal cavity. nasopharynx. However , in susceptible individuals with weaker immune systems , such as the elderly and young children , the bacterium may become pathogenic and spread to other locations to cause disease .. weaker immune systems. immunocompromised. S. pneumoniae is the main cause of community acquired pneumonia and meningitis in children and the elderly , and of septicemia in those infected with HIV .. pneumonia. pneumonia. community acquired pneumonia. community acquired pneumonia. meningitis. meningitis. septicemia. septicemia. HIV. HIV. The organism also causes many types of pneumococcal infections other than pneumonia .. pneumonia. pneumonia. These invasive pneumococcal diseases include bronchitis , rhinitis , acute sinusitis , otitis media , conjunctivitis , meningitis , sepsis , osteomyelitis , septic arthritis , endocarditis , peritonitis , pericarditis , cellulitis , and brain abscess .. meningitis. meningitis. bronchitis. bronchitis. rhinitis. rhinitis. acute sinusitis. acute sinusitis. otitis media. otitis media. conjunctivitis. conjunctivitis. sepsis. sepsis. osteomyelitis. osteomyelitis. septic arthritis. septic arthritis. endocarditis. endocarditis. peritonitis. peritonitis. pericarditis. pericarditis. cellulitis. cellulitis. brain abscess. brain abscess. S. pneumoniae can be differentiated from the viridans streptococci , some of which are also alpha-hemolytic , using an optochin test , as S. pneumoniae is optochin-sensitive .. viridans streptococci. viridans streptococci. alpha-hemolytic. hemolysis ( microbiology ). optochin. optochin. S. pneumoniae can also be distinguished based on its sensitivity to lysis by bile , the so-called `` bile solubility test '' .. lysis. lysis. bile. bile.
