Determinants Of Fine-Scale Heterogeneity In Mosquito-Borne Virus Systems, Elizabeth Handly Mayton

LSU Doctoral Dissertations

ABSTRACT

Arthropod-borne viruses (arboviruses) are the etiological agents of much morbidity and mortality, especially in low- and middle-income countries. Many of these viruses are spread and maintained by mosquitoes, particularly the urban mosquito Aedes aegypti. Zika virus (ZIKV) is responsible for one of the largest vector-borne disease outbreaks in the past decade, affecting millions in Central and South America including a wave of microcephaly among newborns. Mayaro virus (MAYV) is a mosquito-borne virus endemic to South America and is predicted to become an emergent public health threat. Describing the vector-virus transmission systems are critical for understanding the potential spread …

Functional And Phenotypic Evaluation Of Murine Cytomegalovirus Infection Of The Heart, Cassandra Marie Bonavita

LSU Doctoral Dissertations

Human Cytomegalovirus (HCMV) is a ubiquitous pathogen which infects 50-90% of the world population and results in lifelong latent infection with periodic transient reactivations. In immunocompetent populations acute infection is generally asymptomatic but seropositivity is associated with many chronic diseases, including cardiovascular disease. Despite 139 years of research into HCMV pathogenesis there is still no licensed vaccine and many gaps in the general knowledge of the virus. This includes the role of long term infection as it pertains to chronic diseases. In these studies, murine cytomegalovirus (MCMV) was used as a model of HCMV pathogenesis in the heart. MCMV shares …
