They are usually found in pairs (diplococci) and do not form spores and are nonmotile. As 2020-06-08 2013-01-22 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. 2006-03-01 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%). 2021-04-02 View Exam slide 1.doc from ANATOMY 3 at Kharkiv National Medical University. Staphylococcus, Gram stain Streptococcus pneumoniae Streptococcus pneumoniae, Gram stain Neisseria spp., Gram stain … Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), facultative anaerobic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile.

Gram stain, and real-time PCR using S. pneumoniae, N. meningitidis, and H. influenzae specific primers and probes. An antibiotic detection disk bioassay was used to test for the presence of antibiotic activity in CSF. The diagnostic accuracy of tests were evaluated using multiple methods, including direct evaluation of Gram stain and real-time Overview: Streptococcus pneumoniae is a Gram-positive, non-spore-forming, non-motile, lancet-shaped coccus anaerobe and a member of the Streptococcaceae family of bacteria (Figure 1). This organism has a capsule comprised of peptidoglycan and teichoic acid that protecting it from complement C3b opsonization, and is alpha-hemolytic .
