| [gene mutations associated with macrolide-resistance and p1 gene typing of mycoplasma pneumoniae isolated in yamagata, japan, between 2004 and 2013]. | to clarify the epidemiologic features of mycoplasma pneumoniae, we examined 358 m. pneumoniae strains isolated between 2004 and 2013 in yamagata, japan. analysis of macrolide-resistance-associated 23s ribosomal rna (rrna) domain v mutations revealed 6 kinds of mutants (81 a2063g, 43 a2063t, 1 a2063c, 1 a2064c, 4 c2617g and 1 c2617 mutation). there were only two mutants before 2009, but mutants a2063t and a2063g increased in 2009 and from 2010, respectively. the annual ratio of mutants varied fro ... | 2015 | 26548292 |
