Orthomyxo-, paramyxo- and flavivirus infections in wild waterfowl in Finland

Virology Journal, 2008
Background Screening wild birds for viral pathogens has become increasingly important. We tested a screening approach based on blood and cloacal and tracheal swabs collected by hunters to study the prevalence of influenza A, paramyxo-, flavi-, and ...

Apple chlorotic leaf spot virus infection affects the physiology and biochemistry of leaves and the quality of fruits of Tuscany (Italy) autochthonous apple varieties

Plant Pathology, Volume 74, Issue 1, Page 158-170, January 2025.
This study confirmed the presence of ACLSV in Tuscany in Mora and Ruggine apple varieties. ACLSV impaired photosynthesis, particularly in Ruggine, and increased fruit size but reduced its quality. Abstract The present study focused on three autochthonous varieties of apple trees belonging to the old Tuscany germplasm (central Italy), Chitignano, Mora ...

Genotypic characterisation of Avian paramyxovirus type-1 viruses isolated from aquatic birds in Uganda

Onderstepoort Journal of Veterinary Research, 2018
Avian paramyxovirus type-1 (APMV-1) viruses of the lentogenic pathotypes are often isolated from wild aquatic birds and may mutate to high pathogenicity when they cross into poultry and cause debilitating Newcastle disease.

Current Status and Prospects of Virus Elimination in Economically Important Crops of Ethiopia Through Tissue Culture Practices: A Review

Advances in Agriculture, Volume 2025, Issue 1, 2025.
Currently, huge crop losses in countries’ genetic resources result from emerging or re‐emerging plant viral diseases, making food security a constant challenge. A critical examination of recent tissue culture practices in Ethiopia reveals numerous limitations that have contributed to the limited advancements of plant tissue culture (PTC) techniques ...

Molecular Characterization and Phylogenetic Analysis of Velogenic NDV Genotype VII Isolated From an Outbreak in Genotype II‐Vaccinated Poultry Flocks of the Southern Region of Pakistan

BioMed Research International, Volume 2025, Issue 1, 2025.
Despite the administration of multiple doses of the Newcastle disease virus (NDV) vaccine, a high mortality rate (20%–40%) due to NDV was observed in the southern region of Pakistan. In the current study, clinical samples were obtained from affected areas with NDV infection.

Avian Paramyxovirus Type-3 as a Vaccine Vector: Identification of a Genome Location for High Level Expression of a Foreign Gene

Frontiers in Microbiology, 2017
Avian paramyxovirus serotype 3 (APMV-3) causes infection in a wide variety of avian species, but it does not cause apparent diseases in chickens. On the contrary, APMV-1, also known as Newcastle disease virus (NDV), can cause severe disease in chickens ...
