Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

Further Optimization of Controlled Depuration for Eliminating Vibrio parahaemolyticus from Raw Oysters for Safe Consumption

Creator:: Ming, Ziwen
Abstract:: Vibrio parahaemolyticus infections in the United Stated have been linked to consumption of raw shellfish, particularly oysters, with symptoms of headache, abdominal pain, nausea, diarrhea, vomiting. Depuration, as a post-harvest process, has a long history of being applied in shellfish industry to reduce sewage bacteria. In order to reduce the...

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...

Ecology and Environmental Controls of Two Keystone Groups of Oceanic Microorganisms : Diazotrophs and Pathogenic Vibrio

Creator:: Gradoville, Mary Rose
Abstract:: Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

Characterization of Sporulation and Germination Genes in Clostridium perfringens

Creator:: Talukdar, Prabhat Kumar
Abstract:: Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that can produce as many as 17 different toxins and are responsible to cause a wide array of gastrointestinal (GI) and histotoxic diseases in humans and animals. As individual strains produce a subset of these toxins, C. perfringens strains can be classified...

New Insights into the Molecular Mechanism of Clostridium perfringens Spore Germination

Creator:: Banawas, Saeed S.
Abstract:: C. perfringens is a spore-forming, gram-positive, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses. Interestingly, these two major diseases are...

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...

Identification of novel immune molecular pathways and response markers to OmniGen-AF® supplementation in a rat model

Creator:: Branson, Jennifer A.
Abstract:: OmniGen-AF® (OG; Prince Agri Products, Inc., Quincy, IL) is a feed additive containing brewers dehydrated yeast and B-vitamins that supports immune function in ruminant livestock. Targeted profiling of immune-associated genes in whole blood is an effective platform for identification of a) novel molecular pathways and b) immune response markers to...

Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

Creator:: Brown, M. Alex
Abstract:: Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...

Retention of protein repulsive character and antimicrobial activity of PEO brush layers following nisin entrapment

Creator:: Auxier, Julie A.
Abstract:: Nisin, an amphiphilic, antimicrobial peptide, has been shown to integrate into the hydrophobic inner region of poly(ethylene oxide) (PEO) brush layers; however, the presence of integrated nisin may compromise the protein repulsive character of the PEO layer. In particular, the introduction of fibrinogen to nisin-loaded brush layers has been observed...
