Molecular characterization of pneumococcal surface protein K, a potential pneumococcal vaccine antigen

Nasopharyngeal Pneumococcal Colonization among Children after Pneumococcal Conjugate Vaccine Introduction

World Health Organization has recommended all countries to introduction of Pneumococcal Conjugate Vaccine (PCV) in routine immunization schedule, especially those countries with higher rate of mortality in children. However, Islamic Republic of Iran and more than 50 other countries including Algeria, Antigua and Barbuda, Belarus, Belize, Bhutan, Bosnia and Herzegovina, Brunei Darussalam, Cabo V...

Pneumococcal diversity: considerations for new vaccine strategies with emphasis on pneumococcal surface protein A (PspA).

Streptococcus pneumoniae is a problematic infectious agent, whose seriousness to human health has been underscored by the recent rise in the frequency of isolation of multidrug-resistant strains. Pneumococcal pneumonia in the elderly is common and often fatal. Young children in the developing world are at significant risk for fatal pneumococcal respiratory disease, while in the developed world ...

Combination of Pneumococcal Surface Protein A (PspA) with Whole Cell Pertussis Vaccine Increases Protection Against Pneumococcal Challenge in Mice

Streptococcus pneumoniae is the leading cause of respiratory acute infections around the world. In Latin America, approximately 20,000 children under 5 years of age die of pneumococcal diseases annually. Pneumococcal surface protein A (PspA) is among the best-characterized pneumococcal antigens that confer protection in animal models of pneumococcal infections and, as such, is a good alternativ...

Development of a protein antigen based pneumococcal vaccine utilizing a polyanhydride nanoparticle delivery platform

Pneumococcal Capsular Polysaccharide Vaccine

Streptococcus pneumoniae (pneumococcus [Pnc]) is a common bacterial agent found in mild mucosal as well as severe systemic infections. Local infections, such as acute otitis media, are rather common; every child has at least one during the first 2 years of life (1), and Pnc is the causative agent in approximately half of the bacterial culturepositive cases (2). Pneumonia is another disease ofte...
