Abstract: The present invention relates to a probe for detecting bacteria using a peptidoglycan-binding protein, and a method for preparing the same. Also, the present invention relates to a method for detecting bacteria using the probe. The probe for detecting bacteria according to the present invention can specifically detect bacteria. That is, the probe according to the present invention can clearly distinguish between yeast and bacteria and can detect both Gram-negative and Gram-positive bacteria, and thus is expected to be usable in various fields as a universal probe for detecting bacteria. Further, use of the probe allows bacteria to be detected by identifying only fluorescence development without an additional enzymatic treatment, thereby enabling a simple and quick bacterial detection. In particular, the probe is expected to be effectively usable in the food industry where quick bacterial detection is required.
