This was a randomized, double-blinded multicenter cohort study of Finnish children aged 2 to 24 months. The study was designed to evaluate the efficacy of two 7-valent pneumococcal conjuga...
Streptococcus pneumoniae is a major cause of pneumonia, sepsis, bacteremia, and pneumococcal meningitis among infants and children worldwide. The 7-valent conjugate pneumococcal vaccine (P...
The primary purpose of this study is to characterize the immune response to a single dose of 13-valent pneumococcal conjugate vaccine (13vPnC) in children previously vaccinated with a prim...
The 13-valent pneumococcal conjugate vaccine (13vPnC) is being developed for adults to prevent pneumococcal diseases such as meningitis (inflammation of the brain lining), septicemia (bloo...
This study will estimate the incidence of invasive pneumococcal disease in members of the Northern Kaiser Permanente healthcare system during each of the 5 following introduction of Prevna...
The importance of bacterial infections following respiratory syncytial virus (RSV) remains unclear. We evaluated whether variations in RSV epidemic timing and magnitude are associated with variations ...
Several cohort studies have indicated associations between S. pneumoniae and other microbes in the nasopharynx. To study causal relationships between the nasopharyngeal microbiome and pneumococcal car...
Bacteremic pneumonia (BP) accounts for ~35% of invasive pneumococcal disease (IPD) in young children. Our aims were to compare age, seasonal and serotype distribution of BP versus non-BP IPD and to de...
Pneumococci remain the most important cause for community-acquired pneumonia. The colonization of the nasopharynx is prerequisite for their transmission and the colonization of toddlers are an importa...
Changes in pneumococcal serotype-specific carriage and invasive pneumococcal disease (IPD) after the introduction of pneumococcal conjugate vaccine (PCV7) could inform serotype epidemiology patterns f...
Medical and Biotech [MESH] Definitions
A febrile disease caused by STREPTOCOCCUS PNEUMONIAE.
A collective expression for all behavior patterns acquired and socially transmitted through symbols. Culture includes customs, traditions, and language.
Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.
A technique for maintaining or growing TISSUE in vitro, usually by DIFFUSION, perifusion, or PERFUSION. The tissue is cultured directly after removal from the host without being dispersed for cell culture.
Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).
