Mutation and Epistasis in Influenza Virus Evolution

open access: yesViruses, 2018
Influenza remains a persistent public health challenge, because the rapid evolution of influenza viruses has led to marginal vaccine efficacy, antiviral resistance, and the annual emergence of novel strains.

Mosquitoes Transmit Unique West Nile Virus Populations during Each Feeding Episode

open access: yesCell Reports, 2017
Arthropod-borne viruses (arboviruses), such as Zika virus, chikungunya virus, and West Nile virus (WNV), pose continuous threats to emerge and cause large epidemics.

Discovery of Two Novel Negeviruses in a Dungfly Collected from the Arctic

open access: yesViruses, 2020
Negeviruses are a proposed group of insect-specific viruses that can be separated into two distinct phylogenetic clades, Nelorpivirus and Sandewavirus.

SARS-CoV-2 variants: Impact on biological and clinical outcome

open access: yesFrontiers in Medicine, 2022
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that was first identified in December 2019, in Wuhan, China was found to be the etiological agent for a novel respiratory infection that led to a Coronavirus Induced Disease named COVID-19.

Global patterns of avian influenza A (H7): virus evolution and zoonotic threats

open access: yesFEMS Microbiology Reviews, 2019
Avian influenza viruses (AIVs) continue to impose a negative impact on animal and human health worldwide. In particular, the emergence of highly pathogenic AIV H5 and, more recently, the emergence of low pathogenic AIV H7N9 have led to enormous ...

The Revisited Genome of Bacillus subtilis Bacteriophage SPP1

open access: yesViruses, 2018
Bacillus subtilis bacteriophage SPP1 is a lytic siphovirus first described 50 years ago. Its complete DNA sequence was reported in 1997. Here we present an updated annotation of the 44,016 bp SPP1 genome and its correlation to different steps of the ...

Clinical-evolutional particularities of the cryoglobulinemic vasculitis in the case of a patient diagnosed with hepatitis C virus in the predialitic phase [PDF]

open access: yes, 2018
Hepatitis C virus (HCV) represents a fundamental issue for public health, with long term evolution and the gradual appearance of several complications and associated pathologies.

Linking influenza virus evolution within and between human hosts

open access: yesbioRxiv, 2019
Influenza viruses rapidly diversify within individual human infections. Several recent studies have deep-sequenced clinical influenza infections to identify viral variation within hosts, but it remains unclear how within-host mutations fare in the global

Research Note: Characterization and phylodynamic analysis of new infectious bursal disease virus variants circulating in Argentina

open access: yesPoultry Science
: Infectious Bursal Disease is a highly contagious disease that affects young chickens and leads to significant economic losses. Its causal agent is a double-stranded RNA virus that, due to its high error rate during the replication process, gives rise ...

Contact transmission of influenza virus between ferrets imposes a looser bottleneck than respiratory droplet transmission allowing propagation of antiviral resistance [PDF]

open access: yes, 2016
Influenza viruses cause annual seasonal epidemics and occasional pandemics. It is important to elucidate the stringency of bottlenecks during transmission to shed light on mechanisms that underlie the evolution and propagation of antigenic drift, host ...
