| Outline of Final Research Achievements |
It was found that rapid nucleic acid-based diagnosis for the detection of Mycoplasma pneumoniae and rapid susceptibility testing for macrolides (Decision of the therapeutic antibiotics) led to reduction of the symptom, shortening of the duration of treatment at the time of M. pneumoniae infection. The macrolide-resistant mycoplasma suddenly had decreased in 2015 during an investigation period from 2013 through 2015. The major cause was change of prevalence types from macrolide-resistant type I bacteria to macrolide-sensitive type II bacteria. It was recognized that the violent change of the resistance ratio was found with change of the prevalent types.
