口腔細菌Streptococcus intermediusの新展開

It is believed that the reduction of the number of bacteria, such as Pseudomonas aeruginosa, Staphylococcus aureus, Candida and periodontopathogenic bacteria, and forming the healthy oropharyngeal flora by oral health care are effective in preventing aspiration pneumonia. These bacteria are often isolated and cultured from the aspiration pneumonia recurrence-prone patient's pharynxes at the same time. However, the microbiological analyses regarding the aspiration pneumonia have not been performed sufficiently. We have developed the studies on S. intermedius, one of the aspiration pneumonia-causing bacteria and these findings are shedding light on the mechanisms for diabetes mellitus, Sjögren's syndrome and chronic thyroiditis, and the prevention of influenza as well as aspiration pneumonia.
