Porcine reproductive and respiratory syndrome virus (PRRSV) is an enveloped, single stranded, positive sense RNA virus and a member of Arteriviridae. Its genome encodes 10 open reading frames for at least 7 structural proteins and 14 non-structural proteins. Membrane (M), Nuclepcapsid (N), and Glycoprotein-5 (GP5) are the major structural proteins of PRRSV, while Envelope (E), Glycoprotein-2 (GP2), Glycoprotein-3 (GP3), and Glycoprotein-4 (GP4) are the minor structural proteins of PRRSV. GP5 induces neutralizing antibodies and forms heterodimers with M, while N is the most immunogenic protein of PRRSV. Previous studies have shown viral structural proteins are able to form virus-like particles …

Photovoice: Engaging School Communities In Wellness Efforts, Hilary J. Overby

Electronic Theses and Dissertations

Introduction: Currently there are no interactive tools that allow school communities to assess their school wellness needs and foster interest in wellness efforts. PhotoVoice is a participatory action research methodology commonly used in public health that utilizes photography to document and showcase community strengths and weaknesses in order to promote change. Purpose: The purpose of this study was to gather perceptions of a school community after using PhotoVoice to document school wellness efforts 1. Participants: High school students (n=103) and school community members (i.e., residents of community, school faculty) (n=188) were recruited across three school districts. Methods: High school students …
