Streptococcus pneumoniae is the most frequent cause of pneumonia and meningitis. Because S pneumoniae can colonize the upper respiratory tract and antibiotic treatment may inhibit growth, culture-based diagnosis can be problematic. An immunohistochemical assay using a polyclonal antibody against pneumococci was used to test formalin-fixed, paraffin-embedded tissue samples from 46 patients for w...
Streptococcus pneumoniae (the pneumococcus) is an important opportunistic human pathogen killing more than 1 million people each year. Having the availability of a system capable easy genome editing would significantly facilitate drug discovery and efforts to identify new vaccine candidates.
To clarify the discrepancy between increasing resistance and conservative clinical effects of macrolides on macrolide-resistant Streptococcus pneumoniae, the authors evaluated the effects of sub-minimum inhibitory concentrations of macrolides on pneumolysin. In vitro, S. pneumoniae was incubated with 1, 2 and 4 microg.mL(-1) of clarithromycin (CLR) and azithromycin (AZM) for 8 h. Western blot a...
A novel, rapid, and noninvasive test (ODK0501) to detect Streptococcus pneumoniae antigen was evaluated in a Japanese multicenter study. ODK0501 uses polyclonal antibodies to detect C polysaccharide of S. pneumoniae from sputum samples by an immunochromatographic assay. The utility of ODK0501 was evaluated for 161 adult patients with lower respiratory tract infection between March 2006 and Marc...
Streptococcus pneumoniae, esas olarak orta kulak iltihabına, toplum kökenli pnömoniye hatta bazen bakteriyemiye neden olan Gram pozitif bir koktur. Genellikle üriner sistem enfeksiyonu etkeni kabul edilmez. Dizüri şikayetiyle başvuran 58 yaşındaki erkek hastanın tekrarlanan idrar kültürlerinden pneumoniae izole edilmiştir. Hastada başka enfeksiyon belirtisi bulunmamıştır. İdrar analizlerinde he...
The purpose of this study was to identify the major etiological agents responsible for invasive bacterial infections in immunocompetent Korean children. We retrospectively surveyed invasive bacterial infections in immunocompetent children caused by eight major pediatric bacteria, namely Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Streptococcu...
Spanish clones of penicillin-resistant Streptococcus pneumoniae are the most common clones recovered in recent cases of meningitis in Spain. international multiresistant Streptococcus pneumoniae clone resistant to fluoroquinolones and other families of antibiotics. Increasing resistance of Streptococcus pneumoniae to fluoro-quinolones: results of a Hong Kong multicentre study in 2000. Streptoco...
UNLABELLED The distribution, genome location, and evolution of the four paralogous zinc metalloproteases, IgA1 protease, ZmpB, ZmpC, and ZmpD, in Streptococcus pneumoniae and related commensal species were studied by in silico analysis of whole genomes and by activity screening of 154 representatives of 20 species. ZmpB was ubiquitous in the Mitis and Salivarius groups of the genus Streptococcu...
Pneumococcal endocarditis is an uncommon disease. Here, we describe a case of endocarditis caused by Streptococcus pneumoniae in a young man following a nose trauma. In traumas that involve the respiratory system and the mucous membrane, bacterial complications such as colonization and bacteremia and end-organ involvement should be considered by physicians.
The present studies demonstrate that antisera directed against Streptococcus pneumoniae type 14 is opsonic for group B streptococci type III in a neutrophile-mediated bactericidal assay. Specificity was demonstrated by the observations that group B streptococci type III and S. pneumoniae type 14 adsorbed the opsonic activity of anti-S. pneumoniae type 14 antisera. Group B streptococci strain 09...
