Evaluation Of Therapeutics For An Enterovirus 71 Infection In An Ag129 Mouse Model, Christopher Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Discovered in 1969 in California, enterovirus 71 (EV-71) is a serious cause of disease in young children. It is one of the major causative agents of hand, food, and mouth disease (HFMD), and can produce neurological complications, such as meningitis, encephalitis, and an acute flaccid paralysis. For serious cases, the fatality rate can be up to 26%, almost exclusively in young children.

While the virus was initially discovered in the United States, it was soon detected in the Eastern hemisphere, causing outbreaks in Europe and Asia. The largest outbreak occurred in Taiwan in 2008, with approximately 490,000 cases and 128 …

Development Of An Animal Model For Enterovirus For Evaluation D68 For Screening Of Antiviral Therapies, W. Joseph Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enterovirus D68 (EV-D68) virus has become more prevalent over the last 15 to 20 years. EV-D68 attacks the respiratory system and can cause severe disease in individuals who have underlying respiratory problems. There have also been reports of individuals with EV-D68 showing signs of neurological system problems and acute flaccid paralysis. Because of the increase in patients with EV-D68 and also the potential for neurological disease, an animal model is needed to study the disease and to evaluate experimental therapies for EV-D68 infection.

To develop the animal model, 4-week old AG129 mice that lack alpha and beta interferon receptors, making …

Background

A growing number of arenaviruses can cause a devastating viral hemorrhagic fever (VHF) syndrome. They pose a public health threat as emerging viruses and because of their potential use as bioterror agents. All of the highly pathogenic New World arenaviruses (NWA) phylogenetically segregate into clade B and require maximum biosafety containment facilities for their study. Tacaribe virus (TCRV) is a nonpathogenic member of clade B that is closely related to the VHF arenaviruses at the amino acid level. Despite this relatedness, TCRV lacks the ability to antagonize the host interferon (IFN) response, which likely contributes to its inability to …
