Phylogenetic Reconstructions Reveal the Circulation of a Novel Dengue Virus-1V Clade and the Persistence of a Dengue Virus-2 III Genotype in Northeast Brazil

open access: yesViruses, 2023
Dengue fever is among the most significant public health concerns in Brazil. To date, the highest number of Dengue notifications in the Americas has been reported in Brazil, with cases accounting for a total number of 3,418,796 reported cases as of mid ...

Main determinants of human influenza phylodynamics

open access: yes, 2010
As stated in [1], three main mechanisms have been proposed to explain the particular phylodynamic patterns observed in human influenza viruses: - a short-lived full cross-immunity among viral strains [2], - a punctuated evolution of the hemagglutinin (HA)

Bovine Coronavirus: Variability, Evolution, and Dispersal Patterns of a No Longer Neglected Betacoronavirus

open access: yesViruses, 2020
Bovine coronavirus (BoCV) is an important pathogen of cattle, causing severe enteric disease and playing a role in the bovine respiratory disease complex. Similar to other coronaviruses, a remarkable variability characterizes both its genome and biology.

Unraveling the epidemiology of Mycobacterium bovis using whole-genome sequencing combined with environmental and demographic data

open access: yesFrontiers in Veterinary Science, 2023
When studying the dynamics of a pathogen in a host population, one crucial question is whether it transitioned from an epidemic (i.e., the pathogen population and the number of infected hosts are increasing) to an endemic stable state (i.e., the pathogen

An efficient Bayesian inference framework for coalescent-based nonparametric phylodynamics [PDF]

open access: yes, 2015
MotivationThe field of phylodynamics focuses on the problem of reconstructing population size dynamics over time using current genetic samples taken from the population of interest. This technique has been extensively used in many areas of biology but is

A69 Phylodynamics of language evolution [PDF]

open access: yesVirus Evolution, 2019
Abstract We used Bayesian evolutionary analysis to study linguistic data and infer phylogenetic trees of language evolution. Languages were encoded as binary strings indicating the presence or absence of members of cognate classes, the equivalence of classes of words with similar meaning, and shared ancestry.

Phylodynamics of SARS-CoV-2 in France, Europe, and the world in 2020

open access: yeseLife, 2023
Although France was one of the most affected European countries by the COVID-19 pandemic in 2020, the dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) movement within France, but also involving France in Europe and in the world ...

Phylodynamics of the Brazilian feline immunodeficiency virus

open access: yesInfection, Genetics and Evolution, 2017
Feline immunodeficiency virus (FIV), like other retroviruses, displays large genomic divergence when different isolates are compared. In this study, 31 FIV positive samples of domestic cats from Porto Alegre, RS, Brazil were used aiming at a detailed genomic characterization and a better understanding of the molecular epidemiology of the virus in ...

Phylodynamic approaches to studying avian influenza virus

open access: yesAvian Pathology, 2023
Avian influenza viruses can cause severe disease in domestic and wild birds and are a pandemic threat. Phylodynamics is the study of how epidemiological, evolutionary, and immunological processes can interact to shape viral phylogenies. This review summarizes how phylodynamic methods have and could contribute to the study of avian influenza viruses ...

What happened after the epidemic? Equine influenza surveillance sheds light on sources and seasonal risk in the United Kingdom

open access: yesEquine Veterinary Journal, Volume 58, Issue 5, Page 1269-1282, September 2026.
Abstract Background The epidemiology of equine influenza (EI) in the United Kingdom has not been systematically described since the 2019 epidemic. Objectives To summarise UK EI surveillance (2020–2024), quantify outbreak seasonality and assess movement‐related sources. Study Design Retrospective observational analysis of national surveillance and horse
