  • Other Background: We previously revealed that several multiple-locus variable-number tandem-repeat analyses（MLVA）and P1 types of Mycoplasma pneumoniae（M. pneumoniae）cocirculated between 2011 and 2013 in Yamagata, Japan. However, the regional spread of M. pneumoniae infection by genotype is not reported yet. It remains unclear whether there is a difference in the spread of macrolide-resistant M. pneumoniae among genotypes. Methods: Genotypes were labeled according to 4-locus（Mpn 13, 14, 15, and 16）MLVA and P1 types. A total of 208 strains belonging to three major genotypes, i.e., type 4-5-7-2, 1; 4-5-7-3, 1; and 3-5-6-2, 2c, were analyzed by combining with the information of macrolide resistance-associated mutation and the patients’ information including residence. Results and Discussion: The three genotypes were widely distributed over more than four cities and towns in Yamagata Prefecture, cocirculating between late 2011 and early 2013, and there was little difference in the duration of their epidemics. Timing of macrolide-resistant strain appearance during the epidemic period differed between type 4-5-7-2, 1 and type 4-5-7-3, 1, and it did not appear throughout type 3-5-6-2, 2c epidemic. These genotypic differences can account for the variation in the prevalence of macrolide resistance-associated mutations in each of the studied areas.
