Longitudinal anellome dynamics in the upper respiratory tract of children with acute respiratory tract infections Virus Evol. (IF 5.3) Pub Date : 2023-07-13 Le Cao, Yingying Ma, Zhenzhou Wan, Bing Li, Weimin Tian, Chiyu Zhang, Yanpeng Li
Anelloviruses (AVs) are ubiquitous in humans and are the most abundant components of the commensal virome. Previous studies on the diversity, transmission and persistence of AVs mainly focused on the blood or transplanted tissues from adults; however, the profile of the anellome in the respiratory tract in children are barely known. We investigated the anellome profile and their dynamics in the upper

From Vaccine to Pathogen: Modeling Sabin 2 Vaccine Virus Reversion and Evolutionary Epidemiology in Matlab, Bangladesh Virus Evol. (IF 5.3) Pub Date : 2023-07-08 Wesley Wong, Jillian Gauld, Michael Famulare
The oral poliovirus vaccines (OPV) are one of most effective disease eradication tools in public health. However, the oral poliovirus vaccine strains are genetically unstable and can cause outbreaks of circulating, vaccine-derived poliovirus (cVDPV2) that are clinically indistinguishable from wild poliovirus (WPV). Here, we developed a Sabin 2 reversion model that simulates the reversion of Sabin 2

Metagenomics reveals the structure of Mastrevirus-host interaction network within an agro-ecosystem Virus Evol. (IF 5.3) Pub Date : 2023-07-06 Sohini Claverie, Murielle Hoareau, Sélim Ben Chéhida, Denis Filloux, Arvind Varsani, Philippe Roumagnac, Darren P Martin, Jean-Michel Lett, Pierre Lefeuvre
As highly pervasive parasites that sometimes cause disease, viruses are likely major components of all natural ecosystems. An important step towards both understanding the precise ecological roles of viruses and determining how natural communities of viral species are assembled and evolve, is obtaining full descriptions of viral diversity and distributions at ecosystem scales. Here we focused on obtaining

Genome analyses of species A rotavirus isolated from various mammalian hosts in Northern Ireland during 2013-2016. Virus Evol. (IF 5.3) Pub Date : 2023-07-04 Paula Lagan,Mark H Mooney,Ken Lemon
Rotavirus group A (RVA) is the most important cause of acute diarrhoea and severe dehydration in young mammals. Infection in livestock is associated with significant mortality and economic losses and, together with wildlife reservoirs, acts as a potential source of zoonotic transmission. Therefore, molecular surveillance of circulating RVA strains in animal species is necessary to assess the risks

Evolutionary changes in the number of dissociable amino acids on spike proteins and nucleoproteins of SARS-CoV-2 variants Virus Evol. (IF 5.3) Pub Date : 2023-06-29 Anže Božič, Rudolf Podgornik
The spike protein of SARS-CoV-2 is responsible for target recognition, cellular entry, and endosomal escape of the virus. At the same time, it is the part of the virus which exhibits the greatest sequence variation across the many variants which have emerged during its evolution. Recent studies have indicated that with progressive lineage emergence, the positive charge on the spike protein has been

The hidden diversity of ancient bornaviral sequences from X and P genes in vertebrate genomes Virus Evol. (IF 5.3) Pub Date : 2023-06-09 Bea Clarise B Garcia, Yahiro Mukai, Keizo Tomonaga, Masayuki Horie
Endogenous bornavirus-like elements (EBLs) are heritable sequences derived from bornaviruses in vertebrate genomes that originate from transcripts of ancient bornaviruses. EBLs have been detected using sequence similarity searches such as tBLASTn, whose technical limitations may hinder the detection of EBLs derived from small and/or rapidly evolving viral X and P genes. Indeed, no EBLs derived from

Evolution of anelloviruses from a circovirus-like ancestor through gradual augmentation of the jelly-roll capsid protein Virus Evol. (IF 5.3) Pub Date : 2023-05-27 Anamarija Butkovic, Simona Kraberger, Zoe Smeele, Darren P Martin, Kara Schmidlin, Rafaela S Fontenele, Michelle R Shero, Roxanne S Beltran, Amy L Kirkham, Maketalena Aleamotu’a, Jennifer M Burns, Eugene V Koonin, Arvind Varsani, Mart Krupovic
Anelloviruses are highly prevalent in diverse mammals, including humans, but so far have not been linked to any disease and are considered to be part of the ‘healthy virome’. These viruses have small circular single-stranded DNA (ssDNA) genomes and encode several proteins with no detectable sequence similarity to proteins of other known viruses. Thus, anelloviruses are the only family of eukaryotic

Mutual information networks reveal evolutionary relationships within the influenza A virus polymerase Virus Evol. (IF 5.3) Pub Date : 2023-05-25 Sarah Arcos, Alvin X Han, Aartjan J W te Velthuis, Colin A Russell, Adam S Lauring
The influenza A (IAV) RNA polymerase is an essential driver of IAV evolution. Mutations that the polymerase introduces into viral genome segments during replication are the ultimate source of genetic variation, including within the three subunits of the IAV polymerase (PB2, PB1, and PA). Evolutionary analysis of the IAV polymerase is complicated, because changes in mutation rate, replication speed

Comparative whole genome analysis reveals re-emergence of human Wa-like and DS-1-like G3 rotaviruses after Rotarix vaccine introduction in Malawi. Virus Evol. (IF 5.3) Pub Date : 2023-05-22 Chimwemwe Mhango, Akuzike Banda, End Chinyama, Jonathan J Mandolo, Orpha Kumwenda, Chikondi Malamba-Banda, Kayla G Barnes, Benjamin Kumwenda, Kondwani Jambo, Celeste M Donato, Mathew D Esona, Peter N Mwangi, A Duncan Steele, Miren Iturriza-Gomara, Nigel A Cunliffe, Valentine N Ndze, Arox W Kamng’ona, Francis E Dennis, Martin M Nyaga, Chrispin Chaguza, Khuzwayo C Jere
G3 rotaviruses rank among the most common rotavirus strains worldwide in humans and animals. However, despite a robust long-term rotavirus surveillance system from 1997 at Queen Elizabeth Central Hospital in Blantyre, Malawi, these strains were only detected from 1997 to 1999 and then disappeared and re-emerged in 2017, five years after the introduction of the Rotarix rotavirus vaccine. Here we analysed

Variation Within Major Internal Repeats of KSHV In Vivo Virus Evol. (IF 5.3) Pub Date : 2023-05-22 Jan Clement Santiago, Dylan H Westfall, Scott V Adams, Fred Okuku, Warren Phipps, James I Mullins
Kaposi Sarcoma-associated Herpesvirus (KSHV) is the etiologic agent of Kaposi Sarcoma (KS), yet the viral genetic factors that lead to the development of KS in KSHV-infected individuals have not been fully elucidated. Nearly all previous analyses of KSHV genomic evolution and diversity have excluded the three major internal repeat regions: the two origins of lytic replication, IR1 and IR2, and the

Selective events at individual sites underlie the evolution of monkeypox virus clades Virus Evol. (IF 5.3) Pub Date : 2023-05-21 Cristian Molteni, Diego Forni, Rachele Cagliani, Federica Arrigoni, Uberto Pozzoli, Luca De Gioia, Manuela Sironi
In endemic regions (West Africa and the Congo Basin), the genetic diversity of monkeypox virus (MPXV) is geographically structured into two major clades (clade I and II) that differ in virulence and host associations. Clade IIb is closely related to the B.1 lineage, which is dominating a worldwide outbreak initiated in 2022. Lineage B.1 has however accumulated mutations of unknown significance that

Mutation rate, selection, and epistasis inferred from RNA virus haplotypes via neural posterior estimation Virus Evol. (IF 5.3) Pub Date : 2023-05-21 Itamar Caspi, Moran Meir, Nadav Ben Nun, Reem Abu Rass, Uri Yakhini, Adi Stern, Yoav Ram
RNA viruses are particularly notorious for their high levels of genetic diversity, which is generated through the forces of mutation and natural selection. However, disentangling these two forces is a considerable challenge, and this may lead to widely divergent estimates of viral mutation rates, as well as difficulties in inferring fitness effects of mutations. Here, we develop, test, and apply an
