Kalinina 1,2,5  \nAbstract  \nBackground Antimicrobial resistance (AMR) poses a significant global health threat, and an accurate prediction of bacterial resistance patterns is critical for effective treatment and control strategies. In recent years, machine learning (ML) approaches have emerged as powerful tools for analyzing large-scale bacterial AMR data. However, ML methods often ignore evolutionary relationships among bacterial strains, which can greatly impact performance of the ML methods, especially if resistance-associated features are attempted to be detected. Genome-wide association studies (GWAS) methods like linear mixed models accounts for the evolutionary relationships in bacteria, but they uncover only highly significant variants which have already been reported in literature.  \nResults In this work, we introduce a novel phylogeny-related parallelism score (PRPS), which measures  \nwhether a certain feature is correlated with the population structure of a set of samples. We demonstrate that PRPS can be used, in combination with SVM-and random forest-based models, to reduce the number of features  \nin the analysis, while simultaneously increasing models’ performance. We applied our pipeline to publicly available AMR data from PATRIC database for Mycobacterium tuberculosis against six common antibiotics.  \nConclusions Using our pipeline, we re-discovered known resistance-associated mutations as well as new candidate mutations which can be related to resistance and not previously reported in the literature. We demonstrated that taking into account phylogenetic relationships not only improves the model performance, but also yields more biologically relevant predicted most contributing resistance markers.  \nKeywords Machine learning, Phylogeny, Antimicrobial resistance, Tuberculosis  \n*Correspondence:  \nAlperYurtseven [alper.yurtseven@helmholtz-hips.de](alper.yurtseven@helmholtz-hips.de)  \n1 Department of Drug Bioinformatics, Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), Helmholtz Centre for Infection Research (HZI), Campus E8 . 1, Saarbrücken 66123, Saarland, Germany  \n2 Graduate School of Computer Science, Saarland University, Saarbrücken 66123, Saarland, Germany  \n3 Institute of Science and Technology Austria (ISTA), Am Campus 1, Klosterneuburg 3400, Austria  \n4 Centre for Microbiology and Environmental Systems Science, Division of Computational System Biology, University of Vienna, Djerassiplatz 1 A, Wien 1030, Austria  \n5 Faculty of Medicine, Saarland University, Homburg 66421, Saarland, Germany  \nIntroduction  \nMycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), has been a major threat to public health for many years, and remains such a threat now. According to the World Health Organization (WHO), the estimated number of TB-caused deaths in 2021 alone was 1.6 million [1] . TB continues to pose a significant threat to global public health because of its ability to easily transmit and the occurrence of drug-resistant strains of Mtb. In 2019, WHO reposterd over ten million cases, including up to 4.5% of infections with drug resistant bacteria [1] . Early diagnosis and effective treatment are important steps in controlling the spread  \n© The Author(s) 2023.
