| Outline of Final Research Achievements |
A total of 453 isolates were obtained in 18 medical settings in Myanmar. Molecular epidemiological analysis was revealed that 172 Escherichia coli isolates, 71 Klebsiella pneumoniae isolates, 2 Burkholderia cepacian isolates, 4 Citrobacter freundii isolates, 28 Enterobacter spp. isolates, 1 Morganella morganii isolate, 2 Pantoea spp. isolates, 3 Proteus mirabilis isolates, 3 Providencia spp. isolates, 178 Pseudomonas spp. isolates, 1 Raultella ornithinolytica isolate, 1 Serratia marcescens isolate and 4 Shingomonas paucimobilis isolates were identified by 16S rRNA sequencing. These isolates harbored genes encoding metallo-β-lactamases and these carbapenemases encoding genes were associated with carbapenem resistance. In addition, these isolates harbored genes encoding 16S rRNA methylases and these 16S rRNA methylases encoding genes were associated with extremely highly aminoglycoside resistance in these isolates obtained in medical settings in Myanmar.
