Arenavirus Diversity and Phylogeography of Mastomys natalensis Rodents, Nigeria

Emerging Infectious Diseases, 2016
Mastomys natalensis rodents are natural hosts for Lassa virus (LASV). Detection of LASV in 2 mitochondrial phylogroups of the rodent near the Niger and Benue Rivers in Nigeria underlines the potential for LASV emergence in fresh phylogroups of this ...

Ecologic Traits Analysis for Identifying Rodent Hosts for Arenavirus and Hepacivirus in the Americas

Biotropica, Volume 57, Issue 6, November 2025.
Over half of emerging human pathogens originate from wildlife, with rodents serving as key zoonotic hosts. This study used ecological trait‐based models to identify rodent traits associated with arenavirus and hepacivirus infections and detect potential host species across the Americas, our models achieve high predictive accuracy (AUC = 0.92–0.96).

Principal host relationships and evolutionary history of the North American arenaviruses [PDF]

, 2007
A previous study suggested that the genomes of the arenaviruses native to North America are a product of genetic recombination between New World arenaviruses with significantly different phylogenetic histories. The purpose of this study was to extend our

The Biological Characteristics and Mouse Model of Lassa Virus From the First Imported Case in China

MedComm, Volume 6, Issue 8, August 2025.
This is the first case of Lassa fever being introduced to China. A strain of the Lineage IV LASV was successfully isolated, and genomic and mutation analysis were conducted. Infection models were constructed using BALB/c, C57BL/6, and AG129 mice, which were successfully established.

Discovery and biological confirmation of a highly divergent Tacaribe virus in metatranscriptomic data from neotropical bats

mSphere
First isolated from neotropical fruit bats in Trinidad in 1956, Tacaribe virus (TCRV) has rarely been detected since. We searched for New World arenavirus reads in roughly 5.7 million sequencing runs available on public databases using Serratus.

Evaluating the Potential Adverse Effects of Favipiravir on Biochemical, Histopathological, and Spermatological Parameters in Male Rats' Testicular Tissue

Journal of Biochemical and Molecular Toxicology, Volume 39, Issue 6, June 2025.
ABSTRACT Favipiravir is a selective RNA polymerase inhibitor and a broad‐spectrum antiviral drug. Favipiravir reduces cell proliferation by inhibiting RNA transcription, particularly in rapidly proliferating cells such as spermatogonia. The aim of this study was to investigate the effects and mechanism of action of favipiravir (T‐705) on sperm quality ...

Future Developments and Applications of the Vaccines against Dangerous Viral Infections, RNA-Replicon-Based, Obtained from the Venezuelan Equine Encephalomyelitis Virus

Проблемы особо опасных инфекций, 2014
The members of the Filoviridae (Marburg and Ebola viruses) and Arenaviridae (Lassa, Lujo, Machupo, Junin, Guanarito, Sabia viruses) families are the etiological agents of particularly dangerous viral hemorrhagic fevers.
