    Ferguson, Jayde A.
    Abstract:
    Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

    Creator:
    Ramsay, Jennifer Mara
    Abstract:
    Zebrafish, Danio rerio, are widely used as vertebrate research organisms yet little is know about their responses to husbandry stressors. This dissertation examined the whole-body cortisol responses of zebrafish to husbandry stress. Additionally, the effects of stress on the susceptibility to mycobacteriosis and microsporidiosis (Pseudoloma neurophilia) were determined including effects...

  • Mechanisms for the interaction of environmental mycobacteria with host cells

    Creator:
    Harriff, Melanie J.
    Abstract:
    Environmental mycobacteria are important opportunistic pathogens for many hosts, including humans, cattle, and fish. Two well-studied species are Mycobacterium avium subsp. avium, a significant cause of disseminated bacterial disease in patients with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s disease in cattle. Many other species that are...
