Dataset for publication: An inter-laboratory study characterizes the impact of bioinformatic approaches on genome-based cluster detection for foodborne bacterial pathogens
<p>This dataset is part of a dry-lab interlaboratory study conducted across Germany, regarding bacterial outbreak detection based on NGS data, with a focus on bioinformatic analysis of four species to identify potential variability caused by different data analysis approaches and human interpretation. Participants were asked to follow their usual in-house protocols while adhering to the general guidelines. A quality assessment (with sample exclusion) was followed by 7-gene Multilocus-Sequence Typing (MLST), core genome Multilocus Sequencing Typing (cgMLST), and SNP calling. The participants were then asked to identify clusters. The study was not intended to resemble a standard proficiency test with a passing/failing grade, but rather to investigate and quantify obvious variability in the results and, where possible, the reasons for it. For this purpose, the datasets included borderline cases in terms of quality.</p>
BacSPaD: A robust bacterial strains' pathogenicity resource based on integrated and curated genomic metadata
<p>The vast array of omics data in microbiology presents significant opportunities for studying bacterial pathogenesis and creating computational tools for predicting pathogenic potential. However, the field lacks a comprehensive, curated resource that catalogs bacterial strains and their ability to cause human infections. Current methods for identifying pathogenicity determinants often introduce biases and miss critical aspects of bacterial pathogenesis.<br>In response to this gap, we introduce BacSPaD (Bacterial Strains’ Pathogenicity Database), a thoroughly curated database focusing on pathogenicity annotations for a wide range of high-quality, complete bacterial genomes. Our rule-based annotation workflow combines metadata from trusted sources with automated keyword matching, extensive manual curation, and detailed literature review. Our analysis classified 5,502 genomes as pathogenic to humans (HP) and 490 as non-pathogenic to humans (NHP), encompassing 532 species, 193 genera, and 96 families. Statistical analysis demonstrated a significant but moderate correlation between virulence factors and HP classification, highlighting the complexity of bacterial pathogenicity and the need for ongoing research. This resource is poised to enhance our understanding of bacterial pathogenicity mechanisms and aid in the development of predictive models. To improve accessibility and provide key visualization statistics, we developed a user-friendly web interface, accessible at<a href="https://bacspad.altrabio.com/"> </a><a href="https://bacspad.altrabio.com/"><u>https://bacspad.altrabio.com</u></a>.</p>

Species-colored Themisto v3 index with 640k bacterial genomes
<p>This is a Themisto v3 [1] index containing the 639,981 high-quality genomes from 661k bacterial genomes dataset of Blackwell et al. [2]. The index contains all distinct 31-mers of the dataset (both strands). There are 71 billion distinct 31-mers in the data (35.5 billion reverse complement pairs). Each k-mer is annotated with the set of species identifiers that contain that 31-mer. The species identifiers are called colors. There are 2340 distinct colors in the dataset, so the color identifiers range from 0 to 2339.</p> <p>To pseudoalign reads.fastq against the index using 16 threads, install <a href="https://github.com/algbio/themisto">Themisto v3</a>, and use the following command:</p> <pre><code class="language-bash">themisto pseudoalign -q reads.fastq -i themisto_640k/index -t 16 --temp-dir .</code></pre> <p>This will output one line of space-separated integers per read in the input. The first integer on a line is the zero-based rank of the read in the fastq file, and the rest of the integers are the identifiers of colors that are compatible with the read. The file color_names.csv lists the species name and the taxid for each color.</p> <p>The pseudoalignment counts <strong>should not be directly used as abundance estimates</strong> because they only describe which reads are <em>compatible</em> with which species, and a single read may be compatible with many. We recommend using mSWEEP to estimate abundances based on the pseudoalignment data: https://github.com/PROBIC/mSWEEP.</p> <p>--</p> <p>The index was constructed with Themisto v3.0.0 using the following command line parameters:</p> <pre><code class="language-bash">themisto build -i input_file_list.txt --file-colors --reverse-complements -o 640k_bacteria -m 512000 -t 48 -k 31 --temp-dir temp --verbose -d 20</code></pre> <p>The file source_accessions.txt lists the accession numbers of assemblies included in the database.</p> <p>[1] Alanko, J.

skDER Representative Genomes for Select Bacterial Taxa
<p>Genomes belonging to a single genus or order were gathered using a loose search of taxonomic classifications in GTDB R214. By loose we required the string 'g__{GENUSNAME}' to be found in taxonomic info column by GTDB, thus allowing gathering of associated genera (which GTDB suggests are different, but literature/domain experts have yet to rename).</p><p>Genomes belonging to a taxa were dereplicated using skDER (v1.0.7) in "greedy" clustering mode with default values for parameters (99% ANI cutoff, 90% AF cutoff).</p><p>Overview of Files:</p><p>- The 'Genome_Dereplication_Overview.tsv' contains details of all the genomes considered as potential representatives for each taxonomic group and their GTDB R214 taxonomic classifications.</p><p>- 18 _Clustering_Information.txt files which contains the relationship information of non-representative genomes to their nearest representative genome. Generated using the `-n` argument in skder v.1.0.7. </p><p>- 18 tar.gz compressed directories are provided. Each compressed directory features representative genomes in FASTA format determined for a particular taxon using skDER with greedy clustering and default cutoffs.

75 Coral Endolith Bacterial Genomes (MAGs) from Red Sea corals Goniastrea edwardsi and Porites lutea
<p>The skeleton of reef-building corals harbors diverse microbial communities that can supply energy to the coral host tissues and might have an integral role in holobiont nutrient cycling. However, we are lacking functional insight of the endolithic microbiome at large. In particular, the link between endolithic microbiome diversity and encoded genomic potential to supply energy to the coral host during coral bleaching, in the absence of their Symbiodiniaceae photosymbionts, remains poorly understood. Here we assembled endolith bacterial MAGs from DNA of coral skeletons from Goniastrea edwardsi and Porites lutea, two common reef‐building corals from the central Red Sea.</p>
One to host them all: genomics of the diverse bacterial endosymbionts of the spider Oedothorax gibbosus
<p>Bacterial endosymbionts of the groups <em>Wolbachia</em>, <em>Cardinium </em>and <em>Rickettsiaceae </em>are well-known for their diverse effects on their arthropod hosts, ranging from mutualistic relationships to reproductive phenotypes. Here, we analyzed a unique system in which the dwarf spider <em>Oedothorax gibbosus</em> is co-infected with up to five different endosymbionts affiliated with <em>Wolbachia</em>, ‘<em>Candidatus </em>Tisiphia’ (formerly Torix group <em>Rickettsia</em>), <em>Cardinium, </em>and <em>Rhabdochlamydia</em>. Using short-read genome sequencing data, we show that the endosymbionts are heterogeneously distributed among <em>O. gibbosus</em> populations and are frequently found co-infecting spider individuals. To study this intricate host-endosymbiont system on a genome resolved level, we used long-read sequencing to reconstruct closed genomes of the <em>Wolbachia</em>, ‘<em>Ca. </em>Tisiphia’ and <em>Cardinium </em>endosymbionts. We provide insights in the ecology and evolution of the endosymbionts and shed light on the interactions with their spider host. We detected high quantities of transposable elements in all endosymbiont genomes and provide evidence that ancestors of the <em>Cardinium</em>, ‘<em>Ca. </em>Tisiphia’ and <em>Wolbachia </em>endosymbionts have co-infected the same hosts in the past. Our findings contribute to broadening our knowledge about endosymbionts infecting one of the largest animal phyla on earth, and show the usefulness of transposable elements as an evolutionary “contact-tracing” tool.</p>
Genome Sizes of Bacterial Species Detected in Cell-Free DNA of Patients with Acute Leukemia and Sepsis, Including Those Undergoing Bone Marrow Transplantation
<p>Next Generation Sequencing (NGS) analysis of Cell-Free DNA provides valuable insights into a spectrum of pathogenic species (particularly bacterial) in blood. Patients with Sepsis often face problems like delays in treatment regimens (combination or cocktail of antibiotics) due to the long turnaround time (TAT) of classical and standard blood culture procedures. NGS gives results with lower TAT along with high-depth coverage. The use of NGS may be a possible solution to deciding treatment regimens for patients without losing precious time and more accurately possibly saving lives.</p> <p>Our curated dataset is of bacterial species or strains detected along with their genome size in 107 AML patients diagnosed with Sepsis clinically. Cell-free DNA profiles of patients were built and sequencing was done in Illumina (NovaSeq and NextSeq). Bioinformatic analysis was performed using two classification algorithms namely kraken2 and kaiju. For kraken2 based classification reference bacterial index developed by Carlo Ferravante et al (Zenodo 2020) (link: https://zenodo.org/records/4055180) was used, while for kaiju-based classification reference database named "nr_euk" dated "2023-05-10" (link: https://bioinformatics-centre.github.io/kaiju/downloads.html) was used.</p> <p>Genome size annotation is important in metagenomics since for the use of depth of coverage (abundance), genome size is required. In metagenomic classification algorithms like kraken/kraken2 and kaiju output computes reads assigned only and not abundance. In kaiju, the problem is more complicated since the reference database does not have a fasta file but only an index file from which alignment is done. </p> <p>To address the above challenges to compute "depth of coverage" or simply abundance, we build a Genome size annotator tool (https://github.com/patkarlab/Genome-Size-Annotation) which provides genome size for each species detected given its taxid is available. In this tool, the NCBI Datasets tool, NCBI Genome API check tool, and Data Mining from AI search engines like perplexity.ai are used. </p> <p>We have curated two datasets</p> <p>Kraken2 dataset named "FINAL METAGENOMIC DATA MASTERSHEET - kraken_genome_annotation"<br>Kaiju dataset named "FINAL METAGENOMIC DATA MASTERSHEET - kaiju_genome_annotation"</p> <p>*Please note that for kraken2 curated dataset, we used data mining from the AI search engine perplexity.ai while for kaiju we did not use perplexity, ai, and any species whose genome size was not found was labeled "NA"</p>

Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia
Successful prevention and mitigation of biological invasions requires retracing the initial steps of introduction, as well as understanding key elements enhancing the adaptability of invasive species. We studied the genetic diversity of the green alga Caulerpa taxifolia and its associated bacterial communities in several areas around the world. The striking congruence of α and ß diversity of the algal genome and endophytic communities reveals a tight association, supporting the holobiont concept as best describing the unit of spreading and invasion. Both genomic compartments support the hypotheses of a unique accidental introduction in the Mediterranean and of multiple invasion events in Southern Australia. In addition to helping with tracing the origin of invasion, bacterial communities exhibit metabolic functions that can potentially enhance adaptability and competitiveness of the consortium they form with their host. We thus hypothesize that low genetic diversities of both host and symbiont communities may contribute to the recent regression in the Mediterranean, in contrast with the persistence of highly diverse assemblages in southern Australia. This study supports the importance of scaling up from the host to the holobiont for a comprehensive understanding of invasions.
Integrated genome-wide investigations of the housefly, a global vector of diseases reveal unique dispersal patterns and bacterial communities across farms
<p><span><span><span><span><span><span><span><span><span><span><span><b>Background:</b>Houseflies (<i>Musca domestica</i>L.) live in intimate association with numerous microorganisms and is a vector of human pathogens.

Compendium of specialized metabolite biosynthetic diversity encoded in bacterial genomes
<p>Bacterial specialized metabolites are a proven source of antibiotics and cancer therapeutics, but whether we have sampled all the secondary metabolite chemical diversity of cultivated bacteria is not known. We analysed ~ 170,000 bacterial genomes and ~ 47,000 metagenome assembled genomes (MAGs) using a modified BiG-SLiCE and the new clust-o-matic algorithm. We found that only 3% of the natural products potentially encoded in bacterial genomes have been experimentally characterized. We show that the variation of secondary metabolite biosynthetic diversity drops significantly on a genus level, identifying it as an appropriate taxonomic rank for comparison. Equal comparison of genera based on Relative Evolutionary Distance revealed that <em>Streptomyces</em> bacteria encode the largest biosynthetic diversity by far, with <em>Amycolatopsis</em>, <em>Kutzneria</em> and <em>Micromonospora</em> also encoding substantial chemical diversity. Finally we find that several less-well-studied taxa such as Weeksellaceae (Bacteroidota), Myxococcaceae (Myxococcota), <em>Pleurocapsa</em> and Nostocaceae (Cyanobacteria) have potential to produce highly diverse secondary metabolites that warrant further investigation.</p>
