Chikungunya Virus Infection-Associated Bone And Joint Disease, Brad A. Goupil
Chikungunya Virus Infection-Associated Bone And Joint Disease, Brad A. Goupil
LSU Doctoral Dissertations
Chikungunya virus (CHIKV) is a mosquito-borne alphavirus that circulates predominantly in tropical and subtropical regions. Infection results in severe debilitating polyarthralgia during the acute phase of disease, and reports suggest that chronic arthralgia lasting months to years after the initial infection can occur. More severe and prolonged disease has been associated with pre-existing joint disease, though this has not been experimentally examined. In the research presented herein, two established mouse models (adult IRF 3/7 -/- -/- and wild-type C57BL/6J mice) were utilized to characterize CHIKV-associated bone and joint disease and evaluate its impact on the progression of pre-existing osteoarthritis (OA) …

Arbovirus Phenotype Alters Transmission Potential, Rebecca C. Christofferson
LSU Doctoral Dissertations
Extrinsic and environmental factors are known to affect the transmission of arthropod-borne viruses (arboviruses), including variations in the arthropod vector populations. Differences among these factors have been associated with differential transmission and are sometimes used to control the spread of an arbovirus through a vertebrate population in an effort to prevent or disrupt an outbreak. However, diversity in intrinsic viral populations, such as genetic and phenotypic variability, is not often accounted for when considering alterations in transmission. Presented in this dissertation are four experimental studies that explore the contribution of viral intrinsic factors, especially phenotypic variability, to the transmission potential …
