Investigating Vibrio parahaemolyticus interactions with the Pacific oyster, Crassostrea gigas

Creator:: Aagesen, Alisha M.
Abstract:: Vibrio parahaemolyticus is a Gram-negative, halophilic, human pathogenic bacterium ubiquitous in the marine environment. Like many Vibrio species, V. parahaemolyticus commonly associates with shellfish, particularly oysters. Ingestion of a raw or under cooked oysters contaminated with V. parahaemolyticus can cause gastroenteritis, which is typically self-limiting and rarely causes death. Globally,...

Molecular and genetic assessment of selected antiporters and methyl-accepting chemotaxis proteins in Vibrio cholerae

Creator:: Quinn, Matthew J.
Abstract:: The pathogen Vibrio cholerae uses cations as a primary currency of virulence and environmental persistence, using gradients of those cations to move, acquire nutrients, and control virulence gene expression. An understanding of the overlapping roles of bioenergetics and chemotaxis in the virulence and environmental survival of V. cholerae issues from...

Characterization of the Sodium Transporting NADH:Quinone Oxidoreductase (NQR) in Vibrio cholerae

Creator:: Fassio, Sara R.
Abstract:: Vibrio cholerae is the causative agent of cholera, a serious diarrheal disease in developing countries. V. cholerae has a unique redox driven respiration-linked sodium pump, Na⁺ translocating NADH:quinone oxidoreductase (NQR). Several reports previously showed that NQR plays an important role in virulence, metabolism, and sodium homeostasis of V. cholerae. This...

Prevalence of the Haemonchus sp. parasite in Oregon cattle

Creator:: Castle, Kayla
Abstract:: Haemonchus sp. is known to be present in geographical regions of Oregon that are more arid and warm, which has been the preferred climate of this parasite. However, it was not detected in Western Oregon bovine until recently. Haemonchus sp. was first detected in Western Oregon bovine from a fecal...

Identification of an aerotaxis transducer in Vibrio cholerae

Creator:: Boin, Markus A.
Abstract:: The ability to move towards favorable environmental conditions, called chemotaxis, is common among motile bacteria. In particular aerotaxis has been extensively studied in Escherichia coli. Three putative aer gene homologs were identified in the V. cholerae genome designated VCAer-1 (VC0512) VCAer-2 (VCA0658), and VCAer-3 (VCA0988). Deletion analyses indicated that only...

Characterization of Membrane Vesicles Released by the Opportunistic Human Pathogen Mycobacterium avium subsp. hominissuis (MAH) in Response to an in vitro System Mimicking the Phagosomal Environment

Creator:: Chiplunkar, Sanket S.
Abstract:: Mycobacterium avium subsp. hominissuis (MAH) belongs to the most-clinically significant non-tuberculous mycobacterial (NTM) pathogens with constant increase in disease prevalence, mainly in several industrialized western countries where tuberculosis is less prevalent. Upon entry into the alveolar space, MAH is engulfed by resident-macrophages, where the pathogen adapts to the hostile phagosomal...

Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

Creator:: Delgado, Hanna
Abstract:: Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

Development of monoclonal antibody-based assays for the detection of Vibrio tubiashii zinc-metalloprotease (VtpA)

Creator:: Gharaibeh, Dima N., Biel, Frances M., and Häse, Claudia C.
Abstract:: Vibrio tubiashii has been linked to disease outbreaks in molluscan species, including oysters, geoducks, and clams. In particular, oyster hatcheries in the Pacific Northwest have been plagued by intermittent vibriosis since 2006. Accurate detection of vibrios, including V. tubiashii, is critical to the hatcheries in order to allow for rapid...

The Inhibitory Activity of Essential Oil Constituents Against Clostridium perfringens Type A Isolates

Creator:: Alanazi, Saud
Abstract:: C. perfringens type A isolates are the causative agents of C. perfringens type A food poisoning (FP) and non-food-borne (NFB) human gastrointestinal diseases. In this study, we evaluated the antimicrobial effect of essential oil constituents (cinnamaldehyde, eugenol, allyl isothiocyanate (AITC), and carvacrol) against C. perfringens FP and NFB isolates grown...

Inactivation Strategy for Clostridium perfringens Spores Adhered onto Stainless Steel Surfaces

Creator:: Alzubeidi, Yasmeen S.
Abstract:: Clostridium perfringens is a spore-forming pathogenic bacterium that causes a variety of diseases in human and animals. C. perfringens type A isolates produce enterotoxin (CPE) causing food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) diseases including antibiotic-associated diarrhea and sporadic diarrhea. C. perfringens type A food poisoning currently ranks as...
