Bacillus subtilis endospore coat protein solubilization methods for studying effects of high pressure precessing

Creator:: Gandhi, Kalpesh K.
Abstract:: Spores of foodborne pathogens such as Clostridium botulinum, Clostridium perfringens and Bacillus cereus are widely distributed in nature. Presence of those spores in food products, particularly C. botulinum spores in vacuum packed, ready-to-eat low-acid products, is a great safety concern. The research here described is a first effort towards understanding...

Analysis of Betta splendens erythrophore responses to Bacillus cereus cultured in different media

Creator:: Austin, Melissa J.
Abstract:: Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...

Bacterial pathogens and associated toxins involved in erythrophore cell aggregation

Creator:: Hutchison, Janine R.
Abstract:: Current detection methods for bacterial contamination rely on structure based detection of proteins and nucleic acids. While these methods are easy to use and reliable, they cannot evaluate the toxicity of a sample and the potential to cause disease. Previously, erythrophore cells derived from Betta splendens had been suggested as...

Chromatophores as cell-based biosensors for the detection of chemically and biologically toxic substances

Creator:: Dukovcic, Stephanie R.
Abstract:: Cell-based biosensors are function-based detectors that use the physiological response of a living cell to sense biologically stimulating agents. This emerging technology extends the application of current detection methods by reporting on the toxicity of a sample and the potential to cause disease. Previously, Betta splendens erythrophores have been described...

Scours in beef calves: causes and treatments

Creator:: Oregon State University. Extension Service and Villarroel, Aurora
Abstract:: Scours is the common name for diarrhea in calves. Diarrhea is a disease of the digestive system characterized by watery feces and increased frequency of bowel movements. The high water content in the feces results in water loss from the body (dehydration). Along with water, the body loses electrolytes, which...

Grapevine rootstocks for Oregon vineyards

Creator:: Oregon State University. Extension Service, Shaffer, Raymond Glen, Sampalo, T. L., Pinkerton, J., and Vasconcelos, M. C.
Abstract:: Grafting, which involves combining two different varieties or species to form a plant with new characteristics, is a technique known from ancient times in tree fruit and grape production. It was, however, used in viticulture only for certain special cases: to change variety, increase vigor, or increase limestone tolerance.

Preventing crown gall disease using oncogene silencing or VirE1-expressing transgenics

Creator:: Humann, Jodi L.
Abstract:: Crown gall disease is caused by the ubiquitous soil bacterium Agrobacterium tumefaciens which transfers a portion if DNA (T-DNA) into the plant cell. Preventing infection by using the biocontrol strain Agrobacterium radiobacter K84 is currently the only defense for crown gall. Two different resistance strategies were examined in this work....

How to reduce the risk of pesticide resistance in winegrape pests in Oregon [2008]

Creator:: Kaiser, Clive, Pscheidt, Jay W., Walton, Vaughn M., and Skinkis, Patricia A.
Abstract:: Pesticides, including insecticides, acaricides, fungicides, bactericides, and herbicides are essential for maintaining healthy grape crops with reliable yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose...

How to reduce the risk of pesticide resistance in apple pests in Oregon

Creator:: Kaiser, Clive, Azarenko, A. N. (Anita Nina), Spotts, Robert Allen, 1945-, and Oregon State University. Extension Service
Abstract:: Pesticides—including insecticides, acaricides, fungicides, and bactericides are essential for maintaining healthy crops with reliable yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose scale (Quadraspidiotus perniciosus...
