Genotype distribution of Mycoplasma pneumoniae. (A) The pie chart illustrates the proportion of genotypes across different categories: P1-1 (green), P1-2 (blue), P1-2c (orange), and P1-2 g (red). Each slice represents the percentage of each genotype among a total of 421 samples. The right panel displays the genotype distribution across four regions. (B) The absolute number of individuals with each genotype from four regions in China: Zhejiang (southeast), Liaoning (northeast), Guizhou (southwest), and Hubei (central). Frequencies of each genotype and associated resistance mutations are shown.
