THE MICROBIOME AND THE REPRODUCTIVE ECOLOGY OF Dermacentor variabilis AND Dermacentor andersoni IN WESTERN CANADA
… survival of larvae, larval behaviour, and transovarial transmission of bacteria by D. andersoni and D. variabilis. I also compared the microbiomes of engorged females, their eggs and larvae of the two species using next generation sequencing and quantitative PCR assays. The results showed a …

Transcriptional regulation of mosquito oogenesis
… is maintained in natural populations in part by transovarial transmission from infected females to their progeny. Our understanding of the innate immune response in mosquito ovaries is a fundamental step toward understanding the transmission cycle of LACV and other vertically transmitted …

Molecular analysis of La Crosse virus transcription and replication in host cells
… LAC virus is maintained in nature through transovarial transmission from an infected female mosquito to her progeny. The potential molecular basis of these long-term, persistent, nonpathogenic infections was investigated in this dissertation. LAC virus primes transcription of its mRNA by …

Characterization of rickettsial infection dynamics within Dermacentor variabilis and Amblyomma maculatum
… key component of vector competence and pathogen transmission to the mammalian host. Contemporary detection of novel tick hosts for rickettsial species, combined with an unprecedented rise in human cases of SFG rickettsiosis, necessitates a deeper understanding of tick/Rickettsia interactions. The …

Overwintering Mechanisms of La Crosse Virus Vectors
… a complex natural cycle through horizontal transmission with sciurid rodents and Aedes mosquitoes in Virginia. Transovarial transmission also occurs in this host-parasite system and has evolved for the virus to persist through winter. The virus perpetuates in diapause induced embryos and …

Bionomics of Ochlerotatus triseriatus Say (Diptera: Culicidae) and Aedes albopictus Skuse (Diptera: Culicidae) in emerging La Crosse virus foci in Virginia
… human case site, indicating the occurrence of transovarial transmission at this site. The supervised landcover classification for Wise County yielded a landcover map with an overall accuracy of 98% based on comparison of output classification with user-defined ground truth data. Posterior …

Comparative Transmission and Pathogenesis of La Crosse Virus (LACV) Lineages and Evidence for LACV Circulation in Virginia Wildlife
… the Eastern Chipmunk (Tamias striatus) or via transovarial transmission from mother mosquitoes to offspring. Historically, LACV comprised two genetically distinct lineages: lineage I in the Midwest and Appalachian regions and lineage II in the southern region. Lineage I LACV is a growing public …
