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.\r\n\r\nResults: In this work, we introduce a novel phylogeny-related parallelism score (PRPS), which measures whether 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 in 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.\r\n\r\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.","lang":"eng"}],"type":"journal_article","date_published":"2023-12-01T00:00:00Z","article_type":"original","citation":{"chicago":"Yurtseven, Alper, Sofia Buyanova, Amay Ajaykumar A.

We implement an algorithmic solution for the identification of parallel rearrangements in bacterial populations as a tool PaReBrick. The tool takes a collection of strains represented as a sequence of oriented synteny blocks and a phylogenetic tree as input data. It identifies rearrangements, tests them for consistency with a tree, and sorts the events by their parallelism score. The tool provides diagrams of the neighbors for each block of interest, allowing the detection of horizontally transferred blocks or their extra copies and the inversions in which copied blocks are involved. We demonstrated PaReBrick’s efficiency and accuracy and showed its potential to detect genome rearrangements responsible for pathogenicity and adaptation in bacterial genomes.","lang":"eng"}],"intvolume":" 38","ddc":["000"],"status":"public","title":"PaReBrick: PArallel REarrangements and BReaks identification toolkit","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10927","file":[{"success":1,"checksum":"4b5688ff9ac86180ccdf7f82fa33d926","date_updated":"2022-03-28T08:07:46Z","date_created":"2022-03-28T08:07:46Z","file_id":"10930","relation":"main_file","creator":"dernst","content_type":"application/pdf","file_size":3425744,"access_level":"open_access","file_name":"2022_Bioinformatics_Zabelkin.pdf"}],"oa_version":"Published Version","scopus_import":"1","has_accepted_license":"1","article_processing_charge":"No","day":"15","page":"357-363","article_type":"original","citation":{"ieee":"A.

The base of their pathogenicity is the type 3 secretion system (T3SS) encoded by the pINV virulence plasmid, which facilitates host cell invasion and subsequent proliferation. A large family of T3SS effectors, E3 ubiquitin-ligases encoded by the ipaH genes, have a key role in the Shigella pathogenicity through the modulation of cellular ubiquitination that degrades host proteins. However, recent genomic studies identified ipaH genes in the genomes of Escherichia marmotae, a potential marmot pathogen, and an E. coli extracted from fecal samples of bovine calves, suggesting that non-human hosts may also be infected by these strains, potentially pathogenic to humans. We performed a comparative genomic study of the functional repertoires in the ipaH gene family in Shigella and enteroinvasive Escherichia from human and predicted non-human hosts. We found that fewer than half of Shigella genomes had a complete set of ipaH genes, with frequent gene losses and duplications that were not consistent with the species tree and nomenclature. Non-human host IpaH proteins had a diverse set of substrate-binding domains and, in contrast to the Shigella proteins, two variants of the NEL C-terminal domain. Inconsistencies between strains phylogeny and composition of effectors indicate horizontal gene transfer between E. coli adapted to different hosts. These results provide a framework for understanding of ipaH-mediated host-pathogens interactions and suggest a need for a genomic study of fecal samples from diseased animals."}],"project":[{"name":"Evolutionary analysis of gene regulation","grant_number":"I05127","_id":"c098eddd-5a5b-11eb-8a69-abe27170a68f"},{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"isi":1,"quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"external_id":{"pmid":["35477739"],"isi":["000788639400032"]},"language":[{"iso":"eng"}],"doi":"10.1038/s41598-022-10827-3","publication_identifier":{"issn":["2045-2322"]},"month":"04","department":[{"_id":"FyKo"}],"publisher":"Springer Nature","publication_status":"published","pmid":1,"acknowledgement":"The project was initiated with Aygul Minnegalieva and Yulia Yakovleva at the Summer School of Molecular and Theoretical Biology (SMTB-2020), supported by the Zimin Foundation.

Shigella genomes contain numerous insertion sequences (ISs) that lead to pseudogenisation of affected genes and an increase of non-homologous recombination. Here, we study 414 genomes of E. coli and Shigella strains to assess the contribution of genomic rearrangements to Shigella evolution. We found that Shigella experienced exceptionally high rates of intragenomic rearrangements and had a decreased rate of homologous recombination compared to pathogenic and non-pathogenic E. coli. The high rearrangement rate resulted in independent disruption of syntenic regions and parallel rearrangements in different Shigella lineages. Specifically, we identified two types of chromosomally encoded E3 ubiquitin-protein ligases acquired independently by all Shigella strains that also showed a high level of sequence conservation in the promoter and further in the 5′-intergenic region. In the only available enteroinvasive E. coli (EIEC) strain, which is a pathogenic E. coli with a phenotype intermediate between Shigella and non-pathogenic E. coli, we found a rate of genome rearrangements comparable to those in other E. coli and no functional copies of the two Shigella-specific E3 ubiquitin ligases.

Genome sequencing of multiple Streptococcus strains demonstrated high variability in gene content and order even in closely related strains of the same species and created a newly emerged object for genomic analysis, the pan-genome. Here we analysed the genome evolution of 25 strains of Streptococcus suis, 50 strains of Streptococcus pyogenes and 28 strains of Streptococcus pneumoniae.\r\n\r\nResults: Fractions of the pan-genome, unique, periphery, and universal genes differ in size, functional composition, the level of nucleotide substitutions, and predisposition to horizontal gene transfer and genomic rearrangements. The density of substitutions in intergenic regions appears to be correlated with selection acting on adjacent genes, implying that more conserved genes tend to have more conserved regulatory regions.\r\nThe total pan-genome of the genus is open, but only due to strain-specific genes, whereas other pan-genome fractions reach saturation. We have identified the set of genes with phylogenies inconsistent with species and non-conserved location in the chromosome; these genes are rare in at least one species and have likely experienced recent horizontal transfer between species. The strain-specific fraction is enriched with mobile elements and hypothetical proteins, but also contains a number of candidate virulence-related genes, so it may have a strong impact on adaptability and pathogenicity.\r\nMapping the rearrangements to the phylogenetic tree revealed large parallel inversions in all species. A parallel inversion of length 15 kB with breakpoints formed by genes encoding surface antigen proteins PhtD and PhtB in S. pneumoniae leads to replacement of gene fragments that likely indicates the action of an antigen variation mechanism.\r\n\r\nConclusions: Members of genus Streptococcus have a highly dynamic, open pan-genome, that potentially confers them with the ability to adapt to changing environmental conditions, i.e. antibiotic resistance or transmission between different hosts. Hence, integrated analysis of all aspects of genome evolution is important for the identification of potential pathogens and design of drugs and vaccines."}],"publication_status":"published","title":"Micro-evolution of three Streptococcus species: Selection, antigenic variation, and horizontal gene inflow","status":"public","intvolume":" 19","publisher":"Springer Nature","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"8263","year":"2019","date_updated":"2023-02-23T13:28:54Z","date_created":"2020-08-15T11:04:07Z","volume":19,"oa_version":"Published Version","author":[{"orcid":"0000-0003-0120-9319","last_name":"Shelyakin","first_name":"Pavel V.","full_name":"Shelyakin, Pavel V."},{"last_name":"Bochkareva","first_name":"Olga","orcid":"0000-0003-1006-6639","id":"C4558D3C-6102-11E9-A62E-F418E6697425","full_name":"Bochkareva, Olga"},{"last_name":"Karan","first_name":"Anna A.","full_name":"Karan, Anna A."},{"first_name":"Mikhail S.","last_name":"Gelfand","full_name":"Gelfand, Mikhail S."}]},{"abstract":[{"text":"OGs with putative pseudogenes by the number of affected genomes in different chlamydial species.

Despite their parasitic lifestyle and isolated intracellular environment, these bacteria managed to avoid accumulation of deleterious mutations leading to subsequent genome degradation characteristic for many parasitic bacteria.\r\nResults\r\n\r\nWe report pan-genomic analysis of sixteen species from genus Chlamydia including identification and functional annotation of orthologous genes, and characterization of gene gains, losses, and rearrangements. We demonstrate the overall genome stability of these bacteria as indicated by a large fraction of common genes with conserved genomic locations. On the other hand, extreme evolvability is confined to several paralogous gene families such as polymorphic membrane proteins and phospholipase D, and likely is caused by the pressure from the host immune system.\r\nConclusions\r\n\r\nThis combination of a large, conserved core genome and a small, evolvable periphery likely reflect the balance between the selective pressure towards genome reduction and the need to adapt to escape from the host immunity.","lang":"eng"}],"issue":"1","_id":"6898","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Chlamydia pan-genomic analysis reveals balance between host adaptation and selective pressure to genome reduction","status":"public","ddc":["570"],"intvolume":" 20","file":[{"file_id":"6924","relation":"main_file","date_created":"2019-10-01T10:33:17Z","date_updated":"2020-07-14T12:47:44Z","checksum":"b798773c5823012d31c812c9f7975da2","file_name":"2019_BioMed_Sigalova.pdf","access_level":"open_access","creator":"kschuh","file_size":4157175,"content_type":"application/pdf"}],"oa_version":"Published Version","month":"09","publication_identifier":{"eissn":["14712164"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000485256100001"]},"oa":1,"isi":1,"quality_controlled":"1","doi":"10.1186/s12864-019-6059-5","language":[{"iso":"eng"}],"article_number":"710","file_date_updated":"2020-07-14T12:47:44Z","year":"2019","publication_status":"published","publisher":"BioMed Central","department":[{"_id":"FyKo"}],"author":[{"full_name":"Sigalova, Olga M.","last_name":"Sigalova","first_name":"Olga M."},{"full_name":"Chaplin, Andrei V.","last_name":"Chaplin","first_name":"Andrei V."},{"orcid":"0000-0003-1006-6639","id":"C4558D3C-6102-11E9-A62E-F418E6697425","last_name":"Bochkareva","first_name":"Olga","full_name":"Bochkareva, Olga"},{"full_name":"Shelyakin, Pavel V.","first_name":"Pavel V.","last_name":"Shelyakin"},{"full_name":"Filaretov, Vsevolod A.","last_name":"Filaretov","first_name":"Vsevolod A."},{"full_name":"Akkuratov, Evgeny E.","last_name":"Akkuratov","first_name":"Evgeny E."},{"last_name":"Burskaia","first_name":"Valentina","full_name":"Burskaia, Valentina"},{"last_name":"Gelfand","first_name":"Mikhail S.","full_name":"Gelfand, Mikhail S."}],"related_material":{"record":[{"id":"9731","status":"public","relation":"research_data"},{"id":"9783","status":"public","relation":"research_data"},{"relation":"research_data","status":"public","id":"9890"},{"relation":"research_data","status":"public","id":"9892"},{"id":"9893","status":"public","relation":"research_data"},{"id":"9894","status":"public","relation":"research_data"},{"id":"9895","relation":"research_data","status":"public"},{"relation":"research_data","status":"public","id":"9896"},{"status":"public","relation":"research_data","id":"9897"},{"relation":"research_data","status":"public","id":"9898"},{"status":"public","relation":"research_data","id":"9899"},{"relation":"research_data","status":"public","id":"9900"},{"status":"public","relation":"research_data","id":"9901"}]},"date_created":"2019-09-22T22:00:36Z","date_updated":"2023-08-30T06:20:22Z","volume":20},{"month":"09","day":"12","article_processing_charge":"No","oa":1,"citation":{"ieee":"O.
