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%). Se hela listan på emedicine.medscape.com Immunologic detection of pneumococcal capsular material (“bacterial antigen”) generally does not add information beyond what is determined by Gram stain, although nuclear probes may eventually be useful in this situation.

Nature av M PiHl · Citerat av 4 — Other Gram-positive bacteria, such as, streptococci, Enterococcus terobacteriacae, streptococci and others (Dasgupta et Ventilation-associated pneumonia. streptococcus pneumoniae meningitis - also called pneumococcal meningitis, streptococcus pneumoniae meningitis - caused by a gram positive diplococcus, The large number of unconfirmed and PCR-negative cases in HES suggests Gram stain and culture for Streptococcus pneumoniae, Neisseria meningitidis Streptococcus pyogenes is non-motile gram-positive cocci, which contains the Lancefield group A antigen that can cause serious infections such as pharyngitis, Grampositiva och gramnegativa aeroba och anaeroba bakterier, till exempel Salmonella, Shigella, Haemophilus influenzae,. Streptococcus pneumoniae The organism was termed Diplococcus pneumoniae from 1920 because of its characteristic appearance in Gram-stained sputum. It was renamed Streptococcus pneumoniae in 1974 because it was very similar to streptococci. Streptococcus pneumoniae played a central role in demonstrating that genetic material consists of DNA. Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections.

Streptococcus pneumoniae will usually appear as BACKGROUND.

Guarner J(1), Packard MM, Nolte KB, Paddock CD, Shieh WJ, Tondella ML, McGee L, Zaki SR. those organisms that stained blue/violet with Gram’s stain are gram-positive bacteria and include Streptococcus pneumoniae (found in the lungs of those with pneumonia) and Streptococcus pyogenes (from patients with Scarlet fever) while those that were decolorized are gram-negativebacteria such as the Salmonella Typhi that is associated with Micrograph of Gram-stained Streptococcus pneumoniae bacteria in sputum. Capsules around Streptococcus pneumoniae cells. Pneumococcus with a capsule in sputum.

Streptococcus pneumoniae cells are Gram-positive, lancet-shaped cocci (elongated cocci with a slightly pointed outer curvature). Usually, they are seen as pairs of cocci (diplococci), but they may also occur singly and in short chains. When cultured on blood agar, they are alpha hemolytic.

Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, 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 nonmotile.
