Continuous surveillance of potentially zoonotic avian pathogens detects contemporaneous occurrence of highly pathogenic avian influenza viruses (HPAIV H5) and flaviviruses (USUV, WNV) in several wild and captive birds

Emerging Microbes and Infections, 2023
Three avian viral pathogens circulate in Germany with particular importance for animal disease surveillance due to their zoonotic potential, their impact on wild bird populations and/or poultry farms: Highly pathogenic (HP) avian influenza virus (AIV) of

Avian flu: «for whom the bell tolls»?

Вопросы вирусологии
The family Orthomyxoviridae consists of 9 genera, including Alphainfluenza virus, which contains avian influenza viruses. In two subtypes H5 and H7 besides common low-virulent strains, a specific type of highly virulent avian virus have been described to

Determination of cold-adapted influenza virus (Orthomyxoviridae: Alphainfluenzavirus) polymerase activity by the minigenome method with a fluorescent protein

Вопросы вирусологии, 2023
Introduction. Polymerase proteins PB1 and PB2 determine the cold-adapted phenotype of the influenza virus A/Krasnodar/101/35/59 (H2N2), as was shown earlier. Objective.

A Novel Iminosugar UV-12 with Activity against the Diverse Viruses Influenza and Dengue (Novel Iminosugar Antiviral for Influenza and Dengue)

Viruses, 2015
Iminosugars are capable of targeting the life cycles of multiple viruses by blocking host endoplasmic reticulum α-glucosidase enzymes that are required for competent replication of a variety of enveloped, glycosylated viruses.

Lyophilisation of influenza, rabies and Marburg lentiviral pseudotype viruses for the development and distribution of a neutralisation-assay based diagnostic kit [PDF]

, 2014
Pseudotype viruses (PVs) are chimeric, replication-deficient virions that mimic wild-type virus entry mechanisms and can be safely employed in neutralisation assays, bypassing the need for high biosafety requirements and performing comparably to ...

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

The 5' ends of Thogoto virus (Orthomyxoviridae) mRNAs are homogeneous in both length and sequence [PDF]

Journal of Virology, 1996
Thogoto (THO) virus is a tick-borne member of the Orthomyxoviridae whose genome consists of six segments of linear, negative sense, single-stranded RNA. To gain insight into the mechanism by which viral mRNA transcripts are initiated, poly(A)+ RNA isolated from THO virus-infected cells was characterized by (i) primer extension experiments, (ii ...

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Influenza pathogenesis: mechanisms of modulation by agent proteins

Журнал инфектологии, 2015
Modern concepts of the influence of the proteins from viruses-etiological agents of flu – Influenzavirus A, B and C (Orthomyxoviridae) – on the development of different elements of the main disease pathogenesis are analyzed in the review.
