Dynamic Programming Algorithms for Discovery of Antibiotic Resistance in Microbial Genomes

no code implementations29 Nov 2023 Manal Helal, Vitali Sintchenko

The translation of comparative genomics into clinical decision support tools often depends on the quality of sequence alignments.

Multiple Sequence Alignment

Defining Reference Sequences for Nocardia Species by Similarity and Clustering Analyses of 16S rRNA Gene Sequence Data

no code implementations29 Nov 2023 Manal Helal, Fanrong Kong, Sharon C. A. Chen, Michael Bain, Richard Christen, Vitali Sintchenko

The most representative 16S rRNA sequences for individual Nocardia species have been identified as 'centroids' in respective clusters from which the distances to all other sequences were minimized; 110 16S rRNA gene sequences with identifications recorded only at the genus level were classified using machine learning methods.

Clustering Dimensionality Reduction

Linear normalised hash function for clustering gene sequences and identifying reference sequences from multiple sequence alignments

no code implementations29 Nov 2023 Manal Helal, Fanrong Kong, Sharon C-A Chen, Fei Zhou, Dominic E Dwyer, John Potter, Vitali Sintchenko

The combination of MSA with the linear mapping hash function is a computationally efficient way of gene sequence clustering and can be a valuable tool for the assessment of similarity, clustering of different microbial genomes, identifying reference sequences, and for the study of evolution of bacteria and viruses.

Persistence of the Omicron variant of SARS-CoV-2 in Australia: The impact of fluctuating social distancing

no code implementations20 Nov 2022 Sheryl L. Chang, Quang Dang Nguyen, Alexandra Martiniuk, Vitali Sintchenko, Tania C. Sorrell, Mikhail Prokopenko

Our study delineated distinct phases of the Omicron-associated pandemic stage, and retrospectively quantified the adoption of social distancing measures, fluctuating over different time periods in response to the observable incidence dynamics.
