Progress of streptococcus pneumoniae infection and immunity / 国际儿科学杂志

ABSTRACT

Streptococcus pneumoniae( SP) is the leading pathogenic bacteria of invasive bacterial infec-tions in children. It can cause some life-threatening diseases such as pneumonia,meningitis and sepsis. Strepto-coccus pneumoniae frequently colonizes the upper respiratory tract. It is essential to know the host immune re-sponse during the infection. This paper reviews antigenic structure of SP,pneumococcal conjugate vaccine and pneumococcal virulence factors,especially focuses on the immune response including the effect of innate immu-nity,macrophage,neutrophil and T-cell.
