Description

technical field [0001] The present invention relates to prophylactic and / or therapeutic agents for Streptococcus pneumoniae infection. Background technique [0002] Streptococcus pneumoniae is a gram-positive diplococcus known as a resident bacterium of the upper trachea. It is a major respiratory pathogen. [0003] According to the report of the National Institute of Infectious Diseases (Japan), Streptococcus pneumoniae is the pathogenic microorganism with the highest frequency in community-acquired pneumonia (CAP) (non-patent literature 1), and the correlation between CAP and medical care and nursing has been reported in this hospital In the prospective study of pneumonia (NHCAP), the frequencies of Streptococcus pneumoniae were 34.8% and 33.9%, respectively, which were the most (Non-Patent Document 2). Compared with patients who did not have it at all, it climbed to 12.1 times (95% confidence interval [CI] 4.1-36.2) (non-patent document 3). From October 1, 2010 (Heisei...

Problems solved by technology

[0004] However, the existence of Streptococcus pneumoniae resistant to antimicrobial drugs has been confirmed, and there have been reports of inoculation discomfort with vaccines, and new countermeasures are expected due to such problems.
