Avian Paramyxovirus Type 1 in Egypt: Epidemiology, Evolutionary Perspective, and Vaccine Approach

open access: yesFrontiers in Veterinary Science, 2021
Avian orthoavulavirus 1, formerly known as avian paramyxovirus type-1 (APMV-1), infects more than 250 different species of birds. It causes a broad range of clinical diseases and results in devastating economic impact due to high morbidity and mortality ...

Virus shedding in co-infections of low pathogenic avian influenza virus ( H6N2 ) and lentogenic newcastle disease virus (La Sota) in Numida Meleagris [PDF]

open access: yesTrakia Journal of Sciences, 2017
An experiment was conducted to evaluate the effect of a low-pathogenic H6N2 avian influenza A viral strain (LPAIV strain H6N2) on subsequent (after 3 days) vaccination with a lentogenic avian paramyxovirus serotype 1 strain La Sota (APMV-1 strain La Sota)

Revolving ATPase motors as asymmetrical hexamers in translocating lengthy dsDNA via conformational changes and electrostatic interactions in phi29, T7, herpesvirus, mimivirus, E. coli, and Streptomyces

open access: yesExploration, Volume 3, Issue 2, April 2023., 2023
The revolving DNA motors of ATPase have been found in viruses (phi29, T7, herpesvirus, and mimivirus) and bacteria (E. coli and Streptomyces). The motors made of asymmetrical 6 subunits translocate lengthy double‐stranded (ds)DNA. The dsDNA is moved in a circular motion around the inner surface of the motor channel subunits.

Registration of seven powdery mildew‐resistant wild hop germplasm lines

open access: yesJournal of Plant Registrations, Volume 17, Issue 1, Page 171-179, January 2023., 2023
Abstract Cultivation of common hop (Humulus lupulus L.) has increased dramatically during the past decade, with the primary growth occurring in the Pacific Northwest of the United States. A major limitation to hop production is hop powdery mildew [caused by Podosphaera macularis (Wallr.) Braun & Takam].

Dynamic paramyxovirus type 1 seroprevalence maps in broilers in the Valencian Community (eastern Spain) during a five-year period (2008-2012)

open access: yesVeterinární Medicína, 2022
Newcastle disease is a devasting disease in poultry production worldwide, thus it is important to implement control measures to avoid entrance of the disease and its spread in the field.

A Novel Avian Paramyxovirus (Putative Serotype 15) Isolated from Wild Birds

open access: yesFrontiers in Microbiology, 2017
In January 2014, a viral hemagglutinating agent named UPO216 was isolated from fecal droppings of wild birds at the UPO wetland in South Korea during an avian influenza surveillance program.

Experimental infection of mice with avian paramyxovirus serotypes 1 to 9. [PDF]

open access: yesPLoS ONE, 2011
The nine serotypes of avian paramyxoviruses (APMVs) are frequently isolated from domestic and wild birds worldwide. APMV-1, also called Newcastle disease virus, was shown to be attenuated in non-avian species and is being developed as a potential vector ...

Mutations in the fusion protein cleavage site of avian paramyxovirus serotype 4 confer increased replication and syncytium formation in vitro but not increased replication and pathogenicity in chickens and ducks. [PDF]

open access: yesPLoS ONE, 2013
To evaluate the role of the F protein cleavage site in the replication and pathogenicity of avian paramyxoviruses (APMVs), we constructed a reverse genetics system for recovery of infectious recombinant APMV-4 from cloned cDNA.

Experimental infection of hamsters with avian paramyxovirus serotypes 1 to 9

open access: yesVeterinary Research, 2011
Avian paramyxoviruses (APMVs) are frequently isolated from domestic and wild birds throughout the world and are separated into nine serotypes (APMV-1 to -9). Only in the case of APMV-1, the infection of non-avian species has been investigated.
