Pneumokocken är en kapslad grampositiv bakterie under kategorin streptokocker som finns i näsans normalflora hos ungefär hälften av alla barn och även i normalfloran i munhålan och i de övre luftvägarna hos friska personer, men kan komma att bli. Streptococcus pneumoniae är en grampositiv fakultativt anaerob diplokock, som även kan växa i korta kedjor. Den är alfahemolytisk på blodagar och kliniska isolat av pneumokocker bär oftast på en polysackaridkapsel. Beroende på skillnader i kapselns struktur kan pneumokockerna indelas i mer än 90 olika serotyper Streptococcus pneumoniae, Streptococcus oralis, Streptococcus mitis and Streptococcus pseudopneumoniae are closely related species of viridans group streptococci (VGS). VGS belong to the indigenous microbiota in the different tracts of the human body and can be associated with infections such as endocarditis and sepsis

Pneumococcal Infections (Streptococcus pneumoniae

Pneumonia is swelling (inflammation) of the tissue in one or both lungs. It's usually caused by a bacterial infection. It can also be caused by a virus, such as coronavirus (COVID-19). Symptoms of pneumonia. The symptoms of pneumonia can develop suddenly over 24 to 48 hours, or they may come on more slowly over several days Streptococcus pneumoniae is a prevalent human pathogen that is a major cause of community-acquired pneumonia. S. pneumoniae utilizes the competence regulon to initiate its attack on the human host. In the current manuscript, we report 1) the design of cyclic competence-stimulating peptide analogs capable of inhibiting the competence regulon in S. pneumoniae with activities at the low nanomolar. Streptococcus pneumoniae is capable of causing multiple infectious syndromes and occasionally causes outbreaks. The objective of this review is to update prior outbreak reviews, identify control measures, and comment on transmission. We conducted a review of published S. pneumoniae outbreaks, defined as at least two linked cases of S. pneumoniae

Group A Streptococcus (GAS; Streptococcus pyogenes) is a bacterium which can colonise the throat, skin and anogenital tract.It causes a diverse range of skin, soft tissue and respiratory tract. Streptococcus pneumoniae (pneumococcus) can cause a range of different illnesses including sinusitis, otitis media, pneumonia, bacteraemia, osteomyelitis, septic arthritis and meningitis. Vaccines are available that help prevent invasive pneumococcal disease (such as bacteraemia and meningitis) Streptococcus agalactiae or group B streptococcus (GBS)—a gram-positive, β-hemolytic organism in the Streptococcus genus that carries the Lancefield group B antigen. GBS are encapsulated organisms and ten antigenically distinct capsular serotypes have been described (1a, 1b, II-IX) in the Streptococcus mitis group may occur. Streptococcus pneumoniae vaccine may cause false positive results within two days following vaccination and is not recommended within five days following pneumococcal vaccination. This test has only been validated for urine samples. Antigen testing is no Streptococcus pneumoniae is a major human pathogen responsible for enormous global morbidity and mortality. Despite this, the pneumococcus makes up part of the commensal nasopharyngeal flora. How the pneumococcus switches from this commensal to pathogenic state and causes disease is unclear and very likely involves variability in expression of its virulence factors

Streptococcus pneumoniae colonies on a blood agar plate. The bile solubility test causes the lysis of: Optochin disk test, 5 μg/mL or less.

Streptococcus is a genus of spherical Gram-positive bacteria, belonging to the phylum Firmicutes and the lactic acid bacteria group. Cellular division occurs along a single axis in these bacteria, and thus they grow in chains or pairs, hence the name — from Greek streptos, meaning easily bent or twisted, like a chain.Contrast this with staphylococci, which divide along multiple.
