A retrospective study at Yangon Children’s Hospital found resistance to at least one tested antibiotic in 82.5 percent of a selected set of 160 isolates. The single peer-reviewed analysis used blood samples collected during clinical care. Its findings describe particular organisms at one Myanmar hospital, providing local surveillance evidence rather than a national estimate or an individual treatment recommendation.

Selected hospital isolates show high resistance
Bloodstream-infection samples from Yangon Children’s Hospital in Myanmar revealed extensive antibiotic resistance among selected bacterial groups. In this single peer-reviewed retrospective study, 82.5 percent of the 160 analyzed isolates resisted at least one tested antibiotic. An isolate is a bacterial sample separated for laboratory examination. The result describes the analyzed organisms at this hospital rather than resistance among all Myanmar children.[1]
Positive cultures narrow to five bacterial groups
Clinical care generated 4,263 blood samples between August 2023 and July 2025, with 765 positive cultures. The detailed investigation selected five bacterial groups, comprising 160 isolates. The children ranged from birth to thirteen years old. The investigators identified organisms and tested antibiotic susceptibility with disk diffusion and broth microdilution, laboratory methods that assess bacterial growth around antibiotics or at different drug concentrations.[1]
An enzyme test adds a resistance marker
Among Klebsiella pneumoniae, a bacterium in the analyzed set, 62 of 85 isolates resisted meropenem: 72.9 percent. A rapid assay also detected NDM, an enzyme associated with resistance, among 47 percent of the gram-negative set of 134 isolates. These laboratory findings provide local surveillance evidence. The study did not test whether introducing the rapid assay improves patient outcomes, and it cannot determine an individual child’s medication.[1]
