Accurate identification of antibiotic resistance genes (ARGs) is essential for mitigating the spread of antimicrobial resistance. This study introduces a framework that leverages the Nucleotide Transformer (NT) model to predict ARGs in a hybrid dataset consisting of both annotated and non-annotated genes. The NT model was trained using a two-round screened dataset to improve prediction accuracy. The experiment processed non-annotated genomic sequences from NCBI using two distinct methods: sliding window segmentation and CDS annotation with the Prodigal_test tool. These processed sequences were subsequently analyzed by the fine-tuned NT model to predict their antibiotic resistance values. This comparison aimed to improve the real-world predictive performance of the fine-tuned NT model. Predictions from the fine-tuned NT model were cross-validated with BLAST results to assess their feasibility and reliability for non-annotated genes.The dual-track framework (NT prediction + BLAST validation) significantly enhances the reliability of ARG identification and facilitates iterative updates to antibiotic resistance gene databases.

摘要

Accurate identification of antibiotic resistance genes (ARGs) is essential for mitigating the spread of antimicrobial resistance. This study introduces a framework that leverages the Nucleotide Transformer (NT) model to predict ARGs in a hybrid dataset consisting of both annotated and non-annotated genes. The NT model was trained using a two-round screened dataset to improve prediction accuracy. The experiment processed non-annotated genomic sequences from NCBI using two distinct methods: sliding window segmentation and CDS annotation with the Prodigal_test tool. These processed sequences were subsequently analyzed by the fine-tuned NT model to predict their antibiotic resistance values. This comparison aimed to improve the real-world predictive performance of the fine-tuned NT model. Predictions from the fine-tuned NT model were cross-validated with BLAST results to assess their feasibility and reliability for non-annotated genes.The dual-track framework (NT prediction + BLAST validation) significantly enhances the reliability of ARG identification and facilitates iterative updates to antibiotic resistance gene databases.
