Eco-Evolutionary Drivers of Vibrio parahaemolyticus Sequence Type 3 Expansion: Retrospective Machine Learning Approach

Eco-Evolutionary Drivers of Vibrio parahaemolyticus Sequence Type 3 Expansion: Retrospective Machine Learning Approach

Machine learning has been credited for its ability to harness the predictive power of evolution, using pattern recognition to uncover complex associations between biological processes [32]; therefore, it is well-placed for the novel exploration of interacting eco-evolutionary mechanisms in combination.

Molecular Evolutionary Dynamics of Coxsackievirus A6 Causing Hand, Foot, and Mouth Disease From 2021 to 2023 in China: Genomic Epidemiology Study

Molecular Evolutionary Dynamics of Coxsackievirus A6 Causing Hand, Foot, and Mouth Disease From 2021 to 2023 in China: Genomic Epidemiology Study

The slope of the regression line provides an estimate of the rate of evolution in substitutions per site per year, and the intercept with the time-axis constitutes an estimate of the age of the root. The time-scaled tree along with historical population dynamics were estimated using the BEAST package (version 1.10.4) [33]. Information regarding the time of the most recent common ancestor (t MRCA) and the rate of evolution (represented as substitutions per site per year) were derived from this estimation.

Mutational Patterns Observed in SARS-CoV-2 Genomes Sampled From Successive Epochs Delimited by Major Public Health Events in Ontario, Canada: Genomic Surveillance Study

Mutational Patterns Observed in SARS-CoV-2 Genomes Sampled From Successive Epochs Delimited by Major Public Health Events in Ontario, Canada: Genomic Surveillance Study

The adaptive evolution of more transmissible and virulent COVID-19 variants associated with different acquired mutations over time may lead to increased case counts, increased mortality rates, and reduced effectiveness of general COVID-19 vaccines [4].

The Evolution and Disparities of Online Attitudes Toward COVID-19 Vaccines: Year-long Longitudinal and Cross-sectional Study

The Evolution and Disparities of Online Attitudes Toward COVID-19 Vaccines: Year-long Longitudinal and Cross-sectional Study

Therefore, it is essential for us to study the evolution and disparities of attitudes across population groups accompanying the introduction of COVID-19 vaccines. To identify COVID-19 vaccine-related literature, we searched the World Health Organization COVID-19 database [4] with the keywords “vaccine” and “vaccination.”

Phylogenetic and Mutational Analysis of Lassa Virus Strains Isolated in Nigeria: Proposal for an In Silico Study

Phylogenetic and Mutational Analysis of Lassa Virus Strains Isolated in Nigeria: Proposal for an In Silico Study

Therefore, our proposed study would focus on determining the mutational profile of Lassa virus strains isolated in 2018 and 2019 and to compare them with isolates from previous years, identify gene trees that may serve as surrogates for species trees, and help reconstruct the time-scaled evolution of Lassa virus in Nigeria. To our knowledge, no studies have reported a marker gene for Lassa virus in Nigeria.

Isolating SARS-CoV-2 Strains From Countries in the Same Meridian: Genome Evolutionary Analysis

Isolating SARS-CoV-2 Strains From Countries in the Same Meridian: Genome Evolutionary Analysis

Hy Phy 2.5.8 (MP) was used to perform recombination analysis by the genetic algorithm recombination detection method and conduct trimming, stop codon removal, and phylogenetic tree and mixed effects model of evolution (MEME) analyses [12]. The MEME web site was used to read JSON output files and generate MEME images and tables.

The Novel Coronavirus Enigma: Phylogeny and Analyses of Coevolving Mutations Among the SARS-CoV-2 Viruses Circulating in India

The Novel Coronavirus Enigma: Phylogeny and Analyses of Coevolving Mutations Among the SARS-CoV-2 Viruses Circulating in India

Through this genome analyses and phylogenetic approach, we have attempted to focus on the natural evolution of SARS-Co V-2 from its existing ancestors within the zoonotic reservoir. Furthermore, analyzing the novel mutations accumulated within the viral genome over the period with reference to the Wuhan strains (clade O) will underscore their impact on the structure and function of viral proteins.

A Snapshot of SARS-CoV-2 Genome Availability up to April 2020 and its Implications: Data Analysis

A Snapshot of SARS-CoV-2 Genome Availability up to April 2020 and its Implications: Data Analysis

Before carrying out any phylogeny-based analysis of virus evolution and spatiotemporal spread, it is crucial to test the quality of the sequence data, since uneven sampling, the presence of phylogenetic noise, and the absence of a temporal signal can affect the reliability of the results (eg, ancestral state reconstructions, molecular clock calibrations) [22]. SARS-Co V-2 full genome alignments generated from sequences in GISAID [23] at different time points were analyzed as follows.
