MICROBIOLOGY. Streptococcus pneumoniae (pneumococcus): Gram-positive diplococcus with polysaccharide capsule, demonstrated by Quellung reaction or  

pneumococcus. noun + grammatik. A gram-positive bacterium, Streptococcus pneumoniae, that causes pneumonia and other infectious diseases.

頻度. Klebsiella pneumoniae Capsules Bacteria (Gram Negative Bacillus) In a previous post I discussed the Quellung Reaction which is used to visualize capsules produced by the gram positive organism Streptococcus pneumoniae (pneumococcus), There I mentioned that organisms other than the pneumococcus are capable of producing a capsule that surrounds the bacterial cell. Multiplex PCR was able to detect one additional isolate each of Streptococcus pneumoniae and Haemophilus influenzae type b. When compared with multiplex PCR as the gold standard, culture and latex agglutination tests had same sensitivity (80%), specificity (100%), PPV (100%) and NPV (97.8%), whereas Gram stain had poor sensitivity (40%) and good specificity (95.6%).
