Performance of diagnostic tests to detect respiratory viruses in older adults. [PDF]

, 2010
The performance of 4 laboratory methods for diagnosis of viral respiratory tract infections (RTI) in older adults was evaluated. Seventy-four nasopharyngeal (NP) swab specimens were obtained from 60 patients with RTI at a long-term care facility over 2 ...

Viruses associated with pneumonia in adults. [PDF]

, 2012
Viral pneumonia, which is typically associated with disease in childhood, is increasingly recognized as causing problems in adults. Certain viruses, such as influenza virus, can attack fully immunocompetent adults, but many viruses take advantage of more-

Experimental validation and computational modeling of anti-influenza effects of quercetin-3-O-α-L-rhamnopyranoside from indigenous south African medicinal plant Rapanea melanophloeos

BMC Complementary and Alternative Medicine, 2019
Background Influenza A virus (IAV) is still a major health threat. The clinical manifestations of this infection are related to immune dysregulation, which causes morbidity and mortality.

From monolayer to spheroid: assessing influenza a virus infection in 2D and 3D cell culture of A549 and HEK293

Virology Journal
Background and aim Three-dimensional (3D) culture models better mimic cell-to-cell interactions compared to traditional two-dimensional (2D) cultures, providing more physiologically relevant alternative for virus infection studies.

Historical Pandemic and Contemporary Influenza A Viruses Reveal PB2 M631L as a Convergent Adaptation to Human ANP32

Microorganisms
Understanding the genetic changes that allow avian influenza A viruses (IAVs) to switch their natural hosts and establish productive infection in humans is important for pandemic risk assessment. Adaptations in the IAV polymerase are required to overcome

Parenteral vaccination of mammalian livestock with Newcastle disease virus-based vector vaccines offers optimal efficacy and safety [PDF]

, 2011
Newcastle disease virus (NDV) is an avian virus that is being evaluated as a vaccine vector for the delivery of foreign genes in mammals. The use of NDV as a vaccine vector in these species offers two major advantages.

Viable porcine arteriviruses with deletions proximal to the 3 ' end of the genome [PDF]

, 2001
In order to obtain attenuated live vaccine candidates of porcine reproductive and respiratory syndrome virus (PRRSV), a series of deletions was introduced at the 3′ end of the viral genome using an infectious cDNA clone of the Lelystad virus isolate. RNA
