Identification And Characterization Of A Novel Structural Protein Of Porcine Reproductive And Respiratory Syndrome Virus, The Replicase Nonstructural Protein 2, Matthew Allan Kappes Jan 2014

Identification And Characterization Of A Novel Structural Protein Of Porcine Reproductive And Respiratory Syndrome Virus, The Replicase Nonstructural Protein 2, Matthew Allan Kappes

Graduate Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is a rapidly mutating pathogen eliciting respiratory and reproductive disease of high economic consequence. The PRRSV non-structural protein 2 (nsp2) is a large multifunctional protein encoded by the most genetically diverse region of the genome - the selective pressure potentiating mutation within this region is unknown. Here we report the identification of a unique function of nsp2 as a structural component of the PRRSV virion; the first PRRSV structural protein identified which is not expressed from a sub-genomic RNA or regulated via the discontinuous transcription pathway. Through the use of a set of custom ...


Development Of An In Vitro Model And Fluorescent Protein Expression System For The Study Of Highly Abortigenic Campylobacter Jejuni, Moria Ann Borys Jan 2014

Development Of An In Vitro Model And Fluorescent Protein Expression System For The Study Of Highly Abortigenic Campylobacter Jejuni, Moria Ann Borys

Graduate Theses and Dissertations

Campylobacter spp. are a leading cause of sheep abortions worldwide; Campylobacter fetus ssp. fetus has historically been the major culprit. Increasingly, however, C. jejuni has been isolated from cases of sheep abortion, and it has now replaced C. fetus ssp. fetus as the predominant cause of Campylobacter-related ovine abortion in the United States. Emergence of a single tetracycline resistant clone (clone SA) has been implicated as the primary reason for this shift. Virulence factors for clone SA have still not been completely elucidated, and it is not known how this bacterium reaches the uterine and placental tissue from the ...
