Partially published
Macrolide-resistant M.pneumoniae distributed in Japan(2008March~2013December).
The isolation of macrolide-resistant M.pneumoniae from ca 73%(686/939) of clinical specimens collected from pediatric patient in Japan : distribution :61% (69/113)in Kyusyu area, 67%(225/336) in Chugoku area, 93%(75/81) in Shikoku area, 78%(140/176) in Kinki area, 69%(43/62) in Hokkaido area, 83%(95/114) in Tokai area, 58%(21/36) in Kanto area.
Macrolide-resistant M.pneumoniae which was isolated from patient without treatment is 47% (N=156).
MR patients: WBC7621, CRP2.21
MS patients: WBC8332, CRP2
Macrolide-resistant M.pneumoniae strains have single point mutation in the 23SrRNA gene either on A2063G(97%) or on A2063T(2%).
Days of fever
The days of fever with administration of macrolide to patient infected with MR were significantly longer than those of infected with MS (mean of 3.74 days versus 1.23 day, P=0.0001).
We consider that the patients are infected with MR if the days of fever are two and more.
The duration of fever with administration of RKM to pateint infected Mycoplasma were shorter than cases of CAM and AZM.
The days of fever with administration of minocycline and tosufloxacin to patient infected with MR were significantry more effective than macrolide to patient (mean of 1.23days versus 1.57days versus 3.74days).
The quantitative PCR showed that the treatment with macrolide resulted in a mild decrease in amount of MR.
The quantitative PCR showed that the treatment with either tosufloxacin or minocycline resulted in a decrease in amount of MR.
