A comprehensive study was conducted using whole- genome shotgun sequencing technology to examine the micro- biomes of urban environments across different cities worldwide. A subset of the collected samples underwent quality control pro- cedures, and the resistome profile, which represents the collection of AMRs, was determined. Various annotation and statistical techniques were employed, including PCA, MCV, MDFS and RF prediction algorithm. We have also carried out clustering, which gave results consistent with the classification. The main objective was to identify AMRs, which play a crucial role in characterizing the origins of the sampled urban microbiomes. This would aid in determining the geographic location for the isolates, provided by the CAMDA 2023. Although a significant number of AMRs were detected in the urban dataset, only a small subset corresponded to the AMRs associated with the provided isolates. This finding suggests that: either 1) the sequencing depth of the urban samples was insufficient, 2) the isolated species were not dominant in the urban dataset, or 3) the classification methods were limited by incomplete reference databases. Nonetheless, based on the analysis, a subset of cities (Auckland, New York and Tokyo) was identified as potential candidates for the origin of the isolates.
