Bacterial communities in carrion and burying beetle (Silphidae) secretions
Pratt, Carrie J. (2021-05)The family Silphidae contains about two hundred species of carrion and burying beetles divided into two subfamilies: Silphinae and Nicrophorinae. While both groups exhibit necrophagous feeding patterns, they are differentiated ... -
Elucidation of the molecular mechanisms of foodborne human pathogen inactivation by cold atmospheric plasma through RNA-Seq analysis
Timmons, Christopher (2016-07)Foodborne human illness caused by pathogenic bacteria is a significant health and economic burden worldwide. Efficient food decontamination methods that do not alter food quality can greatly alleviate this burden. Cold ... -
Evaluation and Optimization of Bioinformatic Tools for the Detection of Human Foodborne Pathogens in Complex Metagenomic Datasets
Sharp, Gretta Marie (2019-07)Foodborne human pathogens pose a significant risk to human health as each year one in six Americans becomes sick from one of over 31 known human foodborne pathogens. Due to the differences in their growth requirements, ... -
Evaluation of identification and molecular characterization of foodborne pathogens by whole genome sequencing through Illumina and Nanopore
Lopez Guerra, Nicolas Javier (2021-07)As next-generation sequencing (NGS) costs has dropped in recent years, whole genome sequencing (WGS) has been adopted as the primary typing method for pathogens of interest in outbreak surveillance in the U.S. In this ... -
Evaluation of the effects of electrode configuration and power pulse regime on the inactivation efficiency of Salmonella enterica by atmospheric cold plasma
Meeks, Carrie Sue (2022-05)Effective food decontamination method is critical in safeguard food safety in fresh produce worldwide. While there are several commercially available methods for food decontamination many are unsustainable or lack consumer ... -
Fate of salmonella introduced to cantaloupe through natural fruit cracks and flowers, alone or in the presence of the plant pathogen Erwinia tracheiphila
Gautam, Dhiraj (2012-12)Salmonella-tainted cantaloupe has been implicated in foodborne illnesses. We know little about Salmonella ecology on cantaloupe flowers and fruits, and chose to investigate whether it can enter edible tissues, and whether ... -
Identification of Candidate Genes for Biosurfactant Production in Lactobacillus Species
Velasco Vazquez, Pryscila (2017-08-01)Most bacteria are capable of forming biofilms to protect themselves from antimicrobials and other sanitation procedures. Undesired biofilm formation is a serious problem in the food and healthcare industries. Probiotic ...
