Abstract: A method for assessing drug-resistant Klebsiella pneumoniae includes the following steps. A test sample is provided, wherein the test sample includes a Klebsiella pneumoniae. A spectrum analysis step is performed, wherein the test sample is detected by a mass spectrometry method so as to obtain a target mass spectrum data. An assessing step for drug-resistant Klebsiella pneumoniae is performed, wherein the target mass spectrum data is analyzed so as to assess whether the Klebsiella pneumoniae is resistant to a carbapenem antibiotic or a colistin or not. When the Klebsiella pneumoniae is resistant to the carbapenem antibiotic, the target mass spectrum data includes a first anti-carbapenem feature mark, and when the Klebsiella pneumoniae is resistant to the colistin, the target mass spectrum data includes a first anti-colistin feature mark.

Abstract: A method for assessing drug-resistant microorganism includes the following steps. A model establishing step is performed so as to obtain an antibiotic resistance assessing classifier. A test sample is provided. A sample pre-processing step is performed so as to obtain a processed sample. An analysis step is performed so as to obtain a target mass spectrum data. A spectrum pre-processing step is performed so as to obtain a normalized target mass spectrum data. A feature extraction step is performed so as to obtain a spectrum feature. An assessing step is performed, wherein the spectrum feature is analyzed by the antibiotic resistance assessing classifier so as to output an assessed result of drug-resistant microorganism, and the assessed result of drug-resistant microorganism is for assessing whether the test microorganism is a drug-resistant microorganism or not.
