Phylogenetic analysis of the promoter element 2 of paramyxo- and filoviruses

Microbiology Spectrum
Paramyxo- and filovirus genomes are equipped with bipartite promoters at their 3' ends to initiate RNA synthesis. The two elements, the primary promoter element 1 (PE1) and the secondary promoter element 2 (PE2), are separated by a spacer region that ...

Alston Virus, a Novel Paramyxovirus Isolated from Bats Causes Upper Respiratory Tract Infection in Experimentally Challenged Ferrets

Viruses, 2018
Multiple viruses with zoonotic potential have been isolated from bats globally. Here we describe the isolation and characterization of a novel paramyxovirus, Alston virus (AlsPV), isolated from urine collected from an Australian pteropid bat colony in ...

A Conservation Assessment and Systematic Review of the Endangered Spectacled Flying‐Fox 濒危眼镜狐蝠的保护评估与系统综述

Wildlife Letters, Volume 3, Issue 4, Page 173-193, December 2025.
Spectacled flying‐fox Pteropus conspicillatus populations have declined so seriously over two decades that they are now endangered. Inaction has allowed threats to increase. Extreme heat events are now a lethal reality, habitat loss continues almost unabated, and pressure to disperse roosts is ever‐present. Obtaining resources and taking action to help

Efficient and Robust Paramyxoviridae Reverse Genetics Systems

mSphere, 2017
The notoriously low efficiency of Paramyxoviridae reverse genetics systems has posed a limiting barrier to the study of viruses in this family. Previous approaches to reverse genetics have utilized a wide variety of techniques to overcome the technical ...

Cooperative Neuraminidase Activity in a Paramyxovirus

Virology, 1995
Paramyxoviruses possess neuraminidase (NA) activity, i.e., the ability to cleave sialic acid from membrane-bound and soluble glycoconjugates. The activity is associated with a homotetrameric, surface glycoprotein spike, called the hemagglutinin-neuraminidase.

Genotype I Newcastle Disease Virus, Isolated from Wild Duck, Can Protect Chickens Against Newcastle Disease Caused by Genotype VII

Pathogens
Newcastle disease viruses (NDVs) circulating among wild birds and poultry may differ in virulence. Some NDVs cause devastating outbreaks in chickens. The NDV/duck/Moscow/3639/2008 (d3639) strain was isolated from a wild duck.

Inhibiting Human Parainfluenza Virus Infection by Preactivating the Cell Entry Mechanism

mBio, 2019
Paramyxoviruses, specifically, the childhood pathogen human parainfluenza virus type 3, are internalized into host cells following fusion between the viral and target cell membranes.

The origin and prevention of pandemics. [PDF]

, 2010
Despite the fact that most emerging diseases stem from the transmission of pathogenic agents from animals to humans, the factors that mediate this process are still ill defined.
