KARGA: Multi-platform Toolkit for -mer-based Antibiotic Resistance Gene Analysis of High-throughput Sequencing Data.

IEEE EMBS Int Conf Biomed Health Inform 2021 Jul 10;2021. Epub 2021 Aug 10.

Data Intelligence Systems Lab, Department of Epidemiology, College of Public Health and Health Professions, University of Florida, Gainesville, FL, USA.

High-throughput sequencing is widely used for strain detection and characterization of antibiotic resistance in microbial metagenomic samples. Current analytical tools use curated antibiotic resistance gene (ARG) databases to classify individual sequencing reads or assembled contigs. However, identifying ARGs from raw read data can be time consuming (especially if assembly or alignment is required) and challenging, due to genome rearrangements and mutations. Read More

Accurate and Strict Identification of Probiotic Species Based on Coverage of Whole-Metagenome Shotgun Sequencing Data.

Front Microbiol 2019 7;10:1683. Epub 2019 Aug 7.

C&K Genomics, Songpa-gu, South Korea.

Identifying the microbes present in probiotic products is an important issue in product quality control and public health. The most common methods used to identify genera containing species that produce lactic acid are matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA sequence analysis. However, the high cost of operation, difficulty in distinguishing between similar species, and limitations of the current sequencing technologies have made it difficult to obtain accurate results using these tools.

Fast and flexible bacterial genomic epidemiology with PopPUNK.

Genome Res 2019 02 24;29(2):304-316. Epub 2019 Jan 24.

MRC Centre for Global Infectious Disease Analysis, Department of Infectious Disease Epidemiology, Imperial College London, London W2 1PG, United Kingdom.

The routine use of genomics for disease surveillance provides the opportunity for high-resolution bacterial epidemiology. Current whole-genome clustering and multilocus typing approaches do not fully exploit core and accessory genomic variation, and they cannot both automatically identify, and subsequently expand, clusters of significantly similar isolates in large data sets spanning entire species. Here, we describe PopPUNK (ulation artitioning sing ucleotide -mers), a software implementing scalable and expandable annotation- and alignment-free methods for population analysis and clustering.

Nonpareil 3: Fast Estimation of Metagenomic Coverage and Sequence Diversity.

mSystems 2018 May-Jun;3(3). Epub 2018 Apr 10.

School of Civil and Environmental Engineering, Georgia Institute of Technology, Atlanta, Georgia, USA.

Estimations of microbial community diversity based on metagenomic data sets are affected, often to an unknown degree, by biases derived from insufficient coverage and reference database-dependent estimations of diversity. For instance, the completeness of reference databases cannot be generally estimated since it depends on the extant diversity sampled to date, which, with the exception of a few habitats such as the human gut, remains severely undersampled. Further, estimation of the degree of coverage of a microbial community by a metagenomic data set is prohibitively time-consuming for large data sets, and coverage values may not be directly comparable between data sets obtained with different sequencing technologies.
