Molecular Epidemiology and Genetic Diversity of Influenza B Viruses Based on Whole-Genome Analysis in Japan and Myanmar, 2016-2020. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background Influenza B virus (IBV) contributes to seasonal epidemics, but its molecular evolution is less defined than influenza A. We analyzed IBVs collected in Japan and Myanmar (2016–2020) to investigate lineage dynamics, reassortment, and genetic mismatch with vaccine strains. Methods Respiratory specimens from patients with influenza‐like

Antigenic and genetic evolution of contemporary swine H1 influenza viruses in the United States [PDF]

, 2018
Several lineages of influenza A viruses (IAV) currently circulate in North American pigs. Genetic diversity is further increased by transmission of IAV between swine and humans and subsequent evolution.

Bayesian inference of reassortment networks reveals fitness benefits of reassortment in human influenza viruses [PDF]

Proceedings of the National Academy of Sciences, 2019
Significance Genetic recombination processes, such as reassortment, make it complex or impossible to use standard phylogenetic and phylodynamic methods. This is due to the fact that the shared evolutionary history of individuals has to be represented by a phylogenetic network instead of a tree.

Testicular degeneration and infertility following arbovirus infection [PDF]

, 2018
Arboviruses can cause a variety of clinical signs including febrile illness, arthritis, encephalitis and hemorrhagic fever. The recent Zika epidemic highlighted the possibility that arboviruses may also negatively affect the male reproductive tract.

Reassortment Patterns in Swine Influenza Viruses

PLoS Currents, 2009
Previous human influenza pandemics were the results of emerging viruses from non-human reservoirs, with at least two caused by strains of mixed human and avian origin. Also, many cases of swine influenza viruses have reportedly infected humans, including the recent human H1N1 strain, isolated in Mexico and the United States.

Widespread Reassortment Shapes the Evolution and Epidemiology of Bluetongue Virus following European Invasion.

PLoS Pathogens, 2015
Genetic exchange by a process of genome-segment 'reassortment' represents an important mechanism for evolutionary change in all viruses with segmented genomes, yet in many cases a detailed understanding of its frequency and biological consequences is ...

In Vitro Reassortment between Endemic Bluetongue Viruses Features Global Shifts in Segment Frequencies and Preferred Segment Combinations

Microorganisms, 2021
Bluetongue virus (BTV) is an arthropod-borne pathogen that is associated with sometimes severe disease in both domestic and wild ruminants. Predominantly transmitted by Culicoides spp.

Oropouche virus: clinical, epidemiological, and molecular aspects of a neglected orthobunyavirus. [PDF]

, 2017
Oropouche virus (OROV) is an important cause of arboviral illness in Latin American countries, more specifically in the Amazon region of Brazil, Venezuela and Peru, as well as in other countries such as Panama.

Genetic Evolution of Avian Influenza A (H9N2) Viruses Isolated from Domestic Poultry in Uganda Reveals Evidence of Mammalian Host Adaptation, Increased Virulence and Reduced Sensitivity to Baloxavir

Viruses, 2022
A (H9N2) avian influenza A viruses were first detected in Uganda in 2017 and have since established themselves in live bird markets. The aim of this study was to establish the subsequent genetic evolution of H9N2 viruses in Uganda.

A reassortant H9N2 influenza virus containing 2009 pandemic H1N1 internal-protein genes acquired enhanced pig-to-pig transmission after serial passages in swine [PDF]

, 2017
Avian H9N2 and 2009 pandemic H1N1 (pH1N1) influenza viruses can infect pigs and humans, raising the concern that H9N2: pH1N1 reassortant viruses could emerge.
