Infections of the lower respiratory tract, such as pneumonia, are one of the leading causes of death worldwide. Streptococcus pneumoniae might colonize the upper respiratory tract and is the main aetiological agent of community-acquired pneumonia (CAP). In the last decades, several factors related to the host, the microorganism and the antibiotic therapy have been investigated to identify risk ...Study design Detection and serotyping of Streptococcus pneumoniae are important to assess the impact of pneumococcal vaccines. This study describes the diagnostic accuracy of PCR-based detection of S. pneumoniae directly from nasopharyngeal (NP) swabs collected for respiratory virus studies. Methods Active surveillance for community-acquired pneumonia (CAP) in hospitalised adults was performed ...Streptococcus pneumoniae (also known as pneumococcus) is a Gram-positive, extracellular, opportunistic pathogen that colonizes the mucosal surfaces of the human upper respiratory tract (URT).

LytA, major autolysin of Streptococcus pneumoniae, requires access to nascent peptidoglycan. PMC3322828. 10.1074/jbc.M111.318584. The pneumococcal autolysin LytA is a virulence factor involved in autolysis as well as in fratricidal- and penicillin-induced lysis. In this study, we used biochemical and molecular biological approaches to elucidate ...The aim of this study was to study the serotypes and clonal diversity of pneumococci causing invasive pneumococcal disease in Catalonia, Spain, in the era of 13-valent pneumococcal conjugate vaccine (PCV13). In our region, this vaccine is only available in the private market and it is estimated a PC …Pneumocystis jirovecii is a common cause of pneumonia in immunosuppressed patients, especially in those infected with human immunodeficiency virus (HIV) and in those receiving systemic corticosteroids. Symptoms include fever, dyspnea, and dry cough. Diagnosis requires demonstration of the organism in an induced sputum specimen or …Invasive pneumococcal disease: isolation of Streptococcus pneumoniae from normally sterile site in resident of a surveillance area in 2018. ABCs Methodology ABCs personnel routinely contacted all microbiology laboratories serving acute care hospitals in their area to identify cases. Standardized case report forms that include

Streptococcus pneumoniae (SPN) is a globally significant cause of meningitis, the pathophysiology of which involves damage to the brain by both bacterial virulence factors and the host inflammatory response. In most cases of SPN meningitis bacteria translocate from the blood into the central nervous system (CNS). The principal site of SPN translocation into the CNS is not known, with possible ...Streptococcus pneumoniae (pneumococcus) is a major cause of morbidity and mortality world-wide. The initial event in invasive pneumococcal disease is the attachment of encapsulated pneumococci to epithelial cells in the upper respiratory tract.Streptococcus pneumoniae serotype epidemiology is essential since serotype replacement is a concern when introducing new polysaccharide-conjugate vaccines. A novel PCR-based automated microarray assay was developed to assist in the tracking of the serotypes. Autolysin, pneumolysin and eight genes located in the capsular operon were amplified using multiplex PCR. This step was followed by a ... ….

Symptoms of pneumococcal pneumonia, a lung infection, include: Fever and chills. Cough. Rapid breathing or difficulty breathing. Chest pain. Older adults with pneumococcal pneumonia may experience confusion or low alertness, rather than the more common symptoms listed above. Complications of pneumococcal pneumonia include:Etiology. Numerous Streptococcus bacteria can cause meningitis. The most significant one is Streptococcus pneumoniae, probably the leading etiologic agent of meningitis worldwide, both in …Anaerobes: Clostridium species, † Peptococcus species, † Peptostreptococcus species, Bacteroides species, including B. fragilis. † These are not beta-lactamase producing strains and, therefore, are susceptible to ampicillin alone.

Pneumococcal surface protein A (PspA) is a surface protein of Streptococcus pneumoniae that may be a candidate antigen for new pneumococcal vaccines. This study investigates the distribution of PspA clades of the causative strains of adult invasive pneumococcal disease (IPD) in Japan. Of the 1,939 strains isolated from cases of adult IPD during 2014-2019, the PspA clades of 1,932 (99.6% ...SPNEU. Streptococcus pneumoniae Ag, U. 77949-6. Result Id. Test Result Name.
