Influenza D virus (IDV), a new member of the influenza virus family, was first reported in 2011 in swine in Oklahoma, USA, and then soon found in cattle across North America and Eurasia. Earlier studies suggested cattle serve as natural reservoir for IDV. The goal of this study is to perform a retrospective study looking at sera collected from Nebraska beef herds in 2003–2004 and 2014 for evidence...
A new member of the Orthomyxoviridae family, influenza D virus (IDV), was first reported in swine in the Midwest region of the United States. This study aims to extend our knowledge on the IDV epidemiology and to determine the impact of bovine production systems on virus spread. A total of 15 isolates were recovered from surveillance of bovine herds in Mississippi, and two genetic clades of viruses...
Identification of antigenic variants is the key to a successful influenza vaccination program. The empirical serological methods to determine influenza antigenic properties require viral propagation. Here a novel quantitative PCR-based antigenic characterization method using polyclonal antibody and proximity ligation assays, or so-called polyPLA, was developed and validated. This method can detect...
