Illustration of the bacteria Streptococcus pneumoniae showing pairs of bacteria,called diplococci. In humans,Streptococcus pneumoniae is a normal part of the nasal cavity,sinuses and upper respiratory tract flora. Streptococcus pneumoniae can become infectious,particularly when immunity is reduced,causing pneumonia. In pneumonia,the bacteria invade the air sacs (alveoli) in the lungs causing an inflammatory response where plasma,blood and white blood cells fill the lung alveoli. | |
