PCV15 (Vaxneuvance ®) is a sterile suspension of purified capsular polysaccharides from 15 serotypes of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F, and 33F ...Exposure to respiratory pathogens such as Streptococcus pneumoniae (pneumococcus) is a frequent event that can result in immediate clearance, nasal colonisation or disease for the host. Human and mouse studies have shown that natural colonisation is an immunising event. Colonisation is prevalent in children but rare in human adults (<10%), suggesting that despite high pneumococcal exposure ...2010 May;16 (5):411-8. doi: 10.1111/j.1469-0691.2010.03183.x. Streptococcus pneumoniae is a major pathogen of humans, causing diseases such as pneumonia and meningitis. The organism produces several virulence factors that are involved in the disease process. The molecular basis of the action of some of these virulence factors is being elucidated.Streptococcus pneumoniae is an important commensal and pathogen responsible for almost a million deaths annually in children under five. The formation of biofilms by S. pneumoniae is important in nasopharyngeal colonization, pneumonia, and otitis media. Pneumolysin (Ply) is a toxin that contributes significantly to the virulence of S ...

To evaluate the reliability of pneumococcal urinary antigen detection we calculated its sensitivity and positive and negative predictive values, using 3 different reference groups of patients as the gold standard: (1) in definite pneumococcal pneumonias (CAP with S pneumoniae isolated in blood or pleural fluid culture); (2) in probable ...Sketchy Micro. 215.21MB. 0 & 3324 images.

However, diseases caused by non-vaccine type (NVT) S. pneumoniae are increasing. In this study, we report an invasive pneumococcal disease (IPD) caused by NVT multidrug-resistant (MDR) S. pneumoniae transmitted from a vaccinated infant ...

Staphylococcus aureus, also known as "staph," is a gram-positive, beta-hemolytic, catalase, and coagulase-positive bacteria, which is known to cause a wide range of infections in humans. Staph is normally part of the human normal skin and nasal flora, but if it overgrows or if the skin is damaged, then it can cause disease through direct ... Streptococcus pneumoniae (pneumococcus) has long been one of the most prominent bacterial causes of disease in humans and was one of the first to be identified as a cause of human infection [ 1 ]. Since 2000, however, its impact has been blunted by the widespread use of vaccines that largely prevent infection and colonization …Streptococcus pneumoniae (pneumococcus) has long been one of the most prominent bacterial causes of disease in humans and was one of the first to be identified as a cause of human infection [ 1 ]. Since 2000, however, its impact has been blunted by the widespread use of vaccines that largely prevent infection and colonization in young children. ….

Streptococcus pneumoniae, Invasive Disease (IPD-Invasive Pneumococcal Disease) Overview1,2,5 Streptococcus pneumoniae, also called pneumococcus, is a bacteria that causes an acute infection. Some pneumococcal infections are considered "invasive" when the infection occurs in areas parts of the body that are normally sterile.Streptococcus pneumoniae is a Gram-positive, non-flagellated bacterium, often arranged in pairs or short chains of cells (Ye et al., 2018; Paton and Trappetti, 2019). It is widely distributed in nature and often colonizes the mucous membranes of the human upper respiratory organs, mainly targeting immunocompromised people, such as children and ...Streptococcus pneumoniae is a primary cause of meningitis and pneumonia. 1,2 The bacterium is also responsible for a substantial proportion of milder infections, including otitis media and ...

What is an invasive Streptococcus pneumoniae infection?. Streptococcus pneumoniae are bacteria that are commonly found in the nose and throat of children and adults. S. pneumoniae can infect the lungs (pneumonia) or ears (otitis media), but it is considered "invasive" when it is found in the blood, spinal fluid (e.g., meningitis), or other site that normally does not have bacteria present.Pneumococcal Disease. Diseases caused by Streptococcus pneumoniae (the pneumococcus) are a major public health problem worldwide. In the developing world young children and the elderly are most affected; it is estimated that about one million children die of pneumococcal disease every year. Streptococcus pneumoniae is an encapsulated bacteria ...Author Summary Streptococcus pneumoniae bacteria are responsible for serious human infections including meningitis, pneumonia and bacteraemia and are a common cause of otitis media (ear infection) in children. However, they most often reside harmlessly in the infant nasopharynx. An association has long been observed between the type of polysaccharide capsule surrounding the bacteria and ...
