Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Characterization of Spoilage Events on Flavored Milk Products by Paenibacillus odorifer

Creator:: Torres, Alejandro
Abstract:: Flavored milk is a growing category for dairy products; however, it is a perishable product that is subject to microbial spoilage which can lead to a negative consumer experience and lead to lost sales. Flavored milk processors communicated unique spoilage events related to their products, including color loss of strawberry...

Investigating the Impact of the Gut Microbiota on Rodent Behavior and their Interaction with Enteroendocrine Cells

Creator:: Singla, Priyanka
Abstract:: Gut-brain communication consists of bidirectional routes between cognitive centers of the brain and peripheral intestines. This bidirectional communication is the result of the interplay between enteroendocrine cells (EECs), enteric nervous system, central nervous system, the vagus nerve, and our microbiota. Multiple studies have associated gut microbial dysbiosis with neurological disorders...

Developing a system of mutagenesis in Francisella tularensis LVS

Creator:: Flax, Lindsay A.
Abstract:: Francisella tularensis is a gram-negative facultative intracellular coccobacillus that primarily infects macrophages. The causative agent of tularemia, this bacterium is considered among the most infectious organisms known, requiring fewer than ten organisms to cause disease. Although ubiquitous in nature, transmission to humans is rare but can occur via insect bites,...

Inhibition of Clostridium perfringens spore growth by synergistic effects of different antimicrobials

Creator:: Alhabeeb, Rabiaa
Abstract:: Clostridium perfringens is a spore-forming anaerobic organism that is commonly present in fresh meat and poultry. The organism's spores can survive a range of food processing methods. C. perfringens type F isolates are the causative agents of C. perfringens type F food poisoning (FP) and non-food borne (NFB) human gastrointestinal...

Low-temperature depuration and low-temperature high hydrostatic pressure processing as post-harvest interventions for diminishing Vibrio parahaemolyticus contamination in oysters

Creator:: Phuvasate, Sureerat
Abstract:: Vibrio parahaemolyticus is a leading cause of acute gastroenteritis associated with consumption of seafood, particularly raw oysters. The United States Centers for Disease Control and Prevention (CDC) estimated that 45,000 cases of V. parahaemolyticus infection occur each year in the U.S. A recent CDC report revealed that the incidence of...

Lipid based nanocarriers for chemotherapeutic drug docetaxel and vaccine delivery

Creator:: Yanasarn, Nijaporn
Abstract:: Nanoscale drug delivery systems have a great impact in current medical field. These carriers have the potential to improve the efficacy and reduce the toxicity of various medicinal products. A broad variety of different lipid based carriers had been developed and used as delivery systems in the past decades. This...

Efficacy of electrolyzed oxidizing water and ozonated water for microbialdecontamination of fresh strawberries (Fragaria x ananassa)

Creator:: Udompijitkul, Pathima
Abstract:: The objectives of this project were to evaluate the efficacies of electrolyzed oxidizing (EO) and ozonated waters as antimicrobial agents for enhancing the microbiological safety of fresh strawberries (Fragaria x ananassa). The influence of sodium chloride (NaCl) concentrations used for preparing EO water was evaluated on their bactericidal activities against...

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...

Search for a repressor regulator of invasion in Mycobacterium avium

Creator:: Tripathi, Sanjai T.
Abstract:: Mycobacterium avium is an intracellular pathogen that is associated with disseminated infection, especially in patients with acquired immunodeficiency syndrome (AIDS). It appears that patients with AIDS acquire M. avium mostly through the intestinal tract, and that bacteria enter the intestinal wall at the terminal ileum. Previous studies have found that...
