We used Fourier-transform infrared (FTIR) spectroscopy to analyze 4 carbapenem-resistant outbreaks. FTIR distinguished between isolates from different hospitals and uncovered the relatedness between isolates from acute-care hospitals and a post-acute-care hospital. Using higher cutoffs reveals more distant relationships and lower cutoffs support analyses of recent events.
我们使用傅里叶变换红外（FTIR）光谱分析了 4 起碳青霉烯类耐药爆发事件。FTIR 能够区分来自不同医院的分离株，并揭示了来自急性护理医院和后期护理医院的分离株之间的相关性。使用更高的截止值可以揭示更远的关系，而使用更低的截止值则支持对近期事件的分析。
