Cell-Mediated Immunity In Porcine Reproductive And Respiratory Syndrome Virus, Rajeshwari Parida May 2012

Cell-Mediated Immunity In Porcine Reproductive And Respiratory Syndrome Virus, Rajeshwari Parida

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Porcine reproductive and respiratory syndrome virus is a significant swine pathogen which exhibits considerable sequence diversity. In an attempt to identify highly conserved T-cell epitopes contained in proteins of this virus, we examined heptadecamer peptides spanning the sequence of the PRRSV nonstructural proteins 9, 10 and 11, all of them are highly conserved, for their ability to elicit a recall proliferative and interferon-gamma response in peripheral blood mononuclear cells obtained from pigs immunized against the type-II PRRSV strain FL-12. These studies led to the identification of seven peptides, two from each NSP 9 and NSP 10 and, three from NSP …


Role Of Porcine Reproductive And Respiratory Syndrome Virus Non-Structural Protein 1 In Viral Replications And Pathogenesis, Lalit Kumar Beura Aug 2011

Role Of Porcine Reproductive And Respiratory Syndrome Virus Non-Structural Protein 1 In Viral Replications And Pathogenesis, Lalit Kumar Beura

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious agent of significant concern to the global swine industry. PRRSV infection of pigs is initiated by a long viremia after which the virus enters in an extended persistent phase of 3-4 months that ultimately is resolved by the immune system. The delayed and weak host adaptive response is responsible for the protracted convalescence period. An initial sub-optimal innate immune response is postulated to be the reason behind such meager adaptive immune response. A major focus of the studies undertaken in this dissertation was to identify the viral non-structural proteins (nsps) …
