Streptococcus pneumoniae

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 Streptococcus pneumoniae Streptococcus pneumoniae, též pneumococcus, je grampozitivní alfa-hemolytický, aerotolerantní anaerobní kok z rodu Streptococcus. Tato bakterie je významným lidským patogenem, byla identifikována jako hlavní příčina pneumonie konce 19. století a je předmětem mnoha studií humorální imunity

Streptococcus pneumoniae Streptococcus pneumoniae je grampozitivní, fakultativně anaerobní, α-hemolytický, viridující kok, který roste ve dvojicích a má lancetovitý tvar. Běžně kolonizuje sliznici horních cest dýchacích v neopouzdřené formě (kolonizováno je 70 % dětí) Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae (pneumococcus). People with pneumococcal disease can spread the bacteria to others when they cough or sneeze. Pneumococcus bacteria can cause infections in many parts of the body, includin Streptococcus Pneumoniae is a beta-hemolytic, or alpha-hemolytic, gram-positive bacterium. It resides in the human body mainly in the sinuses, nasal cavity and respiratory tract. It does not harm the human body and benefits from it. However, in people who have a weak immune system, this bacterium becomes a pathogen and hence creates and spreads.

There are more than 90 different strains of Streptococcus pneumoniae (S. pneumoniae) bacteria (known as serotypes), some of which cause more serious infection than others Streptococcus pneumoniae ist ein klassischer Erreger von Pneumonien, besonders der Lobärpneumonie. Ungefähr 50% der ambulant erworbenen Pneumonien sollen durch Pneumokokken verursacht sein. Die Bakterien breiten sich entlang der Kohn-Poren aus, deshalb begrenzt sich die Entzündung i.d.R. auf einen Lungenlappen Lo Streptococcus pneumoniae, anche detto pneumococco e un tempo noto come Diplococcus pneumoniae o Diplococcus lanceolatus o Bacillo di Fraenkel, è un batterio gram-positivo appartenente al genere Streptococcus ed è il principale responsabile della polmonite negli adulti Vaccines help prevent pneumococcal disease, which is any type of illness caused by Streptococcus pneumoniae bacteria. There are two kinds of pneumococcal vaccines available in the United States: Pneumococcal conjugate vaccine or PCV13 Pneumococcal polysaccharide vaccine or PPSV2

De Streptococcus pneumoniae (pneumokok) is een grampositieve diplokok die regelmatig de bovenste luchtwegen van mensen koloniseert zonder ziekte te veroorzaken (asymptomatisch dragerschap) [1, 2] Streptococcus pneumoniae (le pneumocoque) est une espèce de bactérie du genre Streptococcus. C'est un important agent pathogène chez l'humain. Il est notamment responsable de nombreuses co-infections : il a, par exemple, aggravé la mortalité lors de la pandémie de grippe espagnole. Son nom initial était Diplococcus pneumonia en 1926 Streptococcus pneumoniae is a rare bacteria that can cause pneumonia, meningitis or a blood stream infection. The disease is spread from person-to-person by direct contact with respiratory secretions, like saliva or mucus. Symptoms generally include an onset of fever and shaking or chills Streptococcus pneumoniae is a non-motile, non-spore forming, gram-positive bacteria of the firmicute phylum. S. pneumoniae is also commonly referred to as pneumococcus [1,2]. Streptococcus pneumoniae are in the shape of a slightly pointed coccus, as seen in Figure 1

Se trata de una bacteria grampositiva de 1,2-1,8 µm de longitud, que presenta una forma oval y el extremo distal lanceolado Streptococcus pneumoniae is a gram-positive, catalase-negative, facultatively anaerobic organism that grows as a single coccus, as diplococci often identifiable because of their lancet shape, and in chains of variable length.

(1,2) In 2009, it is estimated that S pneumoniae was responsible for approximately 43,500 infections and 5,000 deaths in the United States

  1. Streptococcus pneumoniae is also responsible for meningitis via direct spread from the nasopharyngeal niche to the central nervous system (CNS). Direct entry through dural defects is possible. Bacterial components are recognized by receptors of brain cells. This leads to the release of pro-inflammatory cytokines
  2. Streptococcus pneumoniae are Gram-positive bacteria in the shape of a slightly pointed cocci. They are usually found in pairs (diplococci), but are also found singly and in short chains. S. pneumoniae are alpha hemolytic (a term describing how the cultured bacteria break down red blood cells for the purpose of classification). Individual bacteria are between 0.5 and 1.25 micrometers in diameter
  3. Streptococcus pneumoniae or Strep. pneumoniae can be broken down into strepto- which means chain, -coccus, which means round shape, and pneumoniae, which refers to the fact that it causes pneumonia - no surprises there. So, Strep pneumoniae are round bacteria that tend to grow in chains, usually in lancet-looking pairs called diplococci

Streptococcus pneumoniae (pneumococcus) is one of the most common causes of pneumonia, septicemia, and meningitis in children and adults both in developing and developed countries. S. pneumoniae is the most common causative agent in community-acquired pneumonia (CAP). It produces several virulence factors including polysaccharide capsules.

Streptococcus pneumoniae is a bacterium that causes respiratory infections in children and adults as well as meningitis. It is the most common cause of bacterial inner ear infection in children. It is common in adults and the most frequent cause of pneumonia among the elderly and those not able to fight off infections Streptococcus pneumoniae. Streptococcus is a genus of microscopic, single-celled bacteria. The individual cells often join to form pairs and are sometimes found in chains. Each cell is surrounded by a protective capsule. S. pneumoniae was discovered in 1881 by Louis Pasteur Streptococcus pneumoniae scanning electron micrograph of a pair of diplococci. CDC. Capsule A capsule composed of polysaccharide completely envelops the pneumococcal cells. During invasion the capsule is an essential determinant of virulence. The capsule interferes with phagocytosis by preventing complement C3b opsonization of the bacterial. Abstract. Streptococcus pneumoniae (Spn) colonizes the nasopharynx and can cause pneumonia.From the lungs it spreads to the bloodstream and causes organ damage. We characterized the in vivo Spn and mouse transcriptomes within the nasopharynx, lungs, blood, heart, and kidneys using three Spn strains. We identified Spn genes highly expressed at all anatomical sites and in an organ-specific.
