Origins and evolutionary genomics of the novel 2013 avian-origin H7N9 influenza A virus in China: Early findings [PDF]
arXiv, 2013 In March and early April 2013, a new avian-origin influenza A (H7N9) virus (A-OIV) emerged in the eastern China. During the first week of April, the 18 infection cases have been confirmed and 6 people have died since March. This virus has caused global concern as a potential pandemic threat.

Membrane Thickness Sensitivity of Avian Prestin: Implications [PDF]
arXiv, 2023 Avian prestin is sensitive to membrane thickness as much as mammalian prestin, which undergoes conformational transitions in membrane area and thereby drives length changes of the cylindrical cell body of outer hair cells. The membrane thickness dependence of mammalian prestin stems from changes in hydrophobic profile in conformational states ...

Detection of ALV p27 in cloacal swabs and virus isolation medium by sELISA
BMC Veterinary Research, 2019 Background Avian leukosis (AL), which is caused by avian leukosis virus (ALV), has led to substantial economic losses in the poultry industry. The kit used to detect all ALV-positive chickens in breeder flocks is very important for efficiently ...

Forward Hysteresis and Backward Bifurcation Caused by Culling in an Avian Influenza Model [PDF]
arXiv, 2013 The emerging threat of a human pandemic caused by the H5N1 avian influenza virus strain magnifies the need for controlling the incidence of H5N1 infection in domestic bird populations. Culling is one of the most widely used control measures and has proved effective for isolated outbreaks. However, the socio-economic impacts of mass culling, in the face

Punctuated evolution of influenza virus neuraminidase (A/H1N1) under migration and vaccination pressures [PDF]
arXiv, 2012 Influenza virus contains two highly variable envelope glycoproteins, hemagglutinin (HA) and neuraminidase (NA). The structure and properties of HA, which is responsible for binding the virus to the cell that is being infected, change significantly when the virus is transmitted from avian or swine species to humans.

PCD2Vec: A Poisson Correction Distance-Based Approach for Viral Host Classification [PDF]
arXiv, 2023 Coronaviruses are membrane-enveloped, non-segmented positive-strand RNA viruses belonging to the Coronaviridae family. Various animal species, mainly mammalian and avian, are severely infected by various coronaviruses, causing serious concerns like the recent pandemic (COVID-19).

Comparative response of turkeys and chickens to avian lymphoid leukosis virus [PDF]
Avian Pathology, 1983 Response of turkeys and 151(5)x7(1) chickens to prenatal or neonatal inoculation with the avian leukosis virus RAV-1 was compared. Virus-inoculated turkeys and chickens developed viraemia and antibody to. RAV-1. Many of the chickens remained persistently viraemic through the duration of the experiment, whereas in turkeys viraemia was transient ...
