Traditional means for microbial detection can no longer match the pace of today’s food processing and global distribution networks. At the same time, rapid detection of pathogens in foods has never been more important. In the U.S. alone, there are an estimated 47.8 million illnesses, over 127,000 hospitalizations and 3,000-plus deaths attributed to foodborne illness each year. Emerging sensor and detection platforms can provide the timely and actionable information needed to lessen the human and economic burdens levied by foodborne disease. This symposium features presentations on emerging optical, nanotechnological, spectroscopic and electrochemical technologies for pathogen detection, including label-free and high-throughput methods. Novel ligands for pathogen capture will also be examined. Benefits and challenges of these new methods and their comparison with existing techniques will be discussed. Label-free approaches and the advantages of novel bioaffinity ligands will be highlighted.
 
Talks by leading academics and researchers in the military and private sectors will include:

•    Light scattering and spectral pattern recognition for bacterial detection
•    Flow cytometry for rapid detection of pathogens in complex matrices
•    Bioluminescent bacteriorphage for high-throughput detection of pathogens 
•    Antimicrobial peptides as bioaffinity ligands for pathogen detection
•    Parallel capillary electrophoresis for high-throughput detection and characterization of pathogens

2:00  Registration with Exhibit & Poster Viewing 
 
2:20 Chairperson’s Welcome and Opening Remarks
Byron Brehm-Stecher, Ph.D., Associate Professor, Iowa State University 

2:30  Light Scattering and Optical Sensors for High Throughput Screening of Bacterial Pathogens
Arun Bhunia, BVSc, Ph.D., Professor of Molecular Food Microbiology, Center for Food Safety Engineering, Dept. of Food Science and Dept. of Comparative Pathobiology, Purdue University
 

Rapid high throughput pathogen screening tools are crucial in improving safety of our food supply. Current pathogen detection trend emphasizes the application of single platform for detection of multiple pathogens/toxins in a cost effective manner. Our research team is currently developing high throughput nano/biosensor-based screening tools such as fiber optic, cell-based and light scattering for detection of multi-pathogens and toxins from food. Cell-based sensor determines virulence potential and is suitable for confirmation of pathogens or toxins present in a sample while light scattering sensor is a label-free method for real-time detection and identification of bacterial colonies on agar plates. While light scattering sensor can detect and identify bacterial colonies on plate without the use of any labeling reagents. It can also be used for bacterial community analysis on products and for process verification, and hygiene monitoring. Limit of detection, specificity, automation and application of each sensor with various sample matrices will be discussed. 
 
 
3:00  Flow Cytometry for Rapid Detection of Pathogens in Complex Matrices
Byron Brehm-Stecher, Ph.D., Associate Professor, Iowa State University
Flow cytometry (FCM) is a rapid method for analysis of cells in liquid suspension. Although FCM was originally developed for measurement of mammalian cells, it has found increasing use in microbiology over the past two decades. FCM allows collection of data at the single cell level on cell physiology, number, viability, genetic identity and other parameters. Depending on the staining technique used, FCM can also be a very robust means for analysis of complex samples, enabling operators to differentiate between cells of interest and high backgrounds of particulate matter or non-target microflora. This talk will provide an overview of FCM and its applications in food microbiology for the detection and characterization of foodborne microorganisms. 
 
3:30  Parallel Capillary Electrophoresis for High-Throughput Detection and Characterization of Pathogens
Pierre Vareneau, Ph.D., Chief Technology Officer, Advanced Analytical Technologies, Inc.
Capillary electrophoresis (CE) has long been a workhorse technology in analytical chemistry labs. CE provides rapid and efficient separations of biologically relevant molecules or compounds, can be used to analyze small sample volumes and typically requires minimal sample preparation. A key advantage of CE is its superior ability to separate complex pools of nucleic acid fragments that present distinct challenges to the gel-based electrophoresis systems that are most commonly used for DNA analysis. This talk will focus on the use of high-throughput parallel CE for nucleic acid-based analysis of foodborne pathogens, contrasting this approach from traditional analyses, including gel-based systems. Additional applications of parallel CE, including next-generation sequencing and related uses will be discussed.

4:30  Antimicrobial Peptide Sensor Arrays for Endotoxin Detection and Discrimination: Towards Microbial Forensics Applications
Joshua R. Uzarski, PhD, Research Scientist, Battelle Memorial Institute, contractor for US Army Natick Soldier Research, Development, and Engineering Center

Lipopolysaccharides, also called endotoxin, shed from Gram negative bacterial pathogens, are the cause of septic shock syndrome and are a pressing issue in sterile environments including health and food preparation facilities. Current detection methods are insufficient, being both temporally and monetarily expensive. We have developed a method using a small array of antimicrobial peptides that detect and discriminate LPS molecules from different bacterial species, strains, and also from different original growth conditions. The latter example might help identify the source of an endotoxin or pathogen outbreak, augmenting the field of microbial forensics. 

5:00  Bioluminescence-transducing phage for detection/identification of E. coli O157:H7 
Bruce Applegate, Associate Professor in Biological Sciences and Food Science, Purdue University*

Shiga-toxigenic strains of E. coli, especially E. coli O157:H7, are most frequently associated with beef and produce, and they can cause serious disease such as severe bloody diarrhea and potentially fatal hemolytic uremic syndrome. We have developed O157:H7-specific bacteriophage ΦV10 to transduce luxCDABE, causing the pathogen to bioluminesce if it is present. We have tested ΦV10-luxagainst diluted O157:H7 at 37°C in beef and romaine lettuce selective enrichments following the protocols from the USDA FSIS and FDA BAM, respectively. Using a luminometer to detect bioluminescence, initial inocula of 10 CFU/g could be detected in beef and 103CFU/g in lettuce in 12 hours, giving a putative positive result even before the real-time PCR step of current protocols.*Carla Rosenfield, PhD candidate in Biological Science, Purdue University 

 

 
 
5:30  Close of Symposium 
 
 
 
 
 
 
 
 
Industry, government and academic scientists are encouraged to submit poster titles for this event. One-page abstracts (8 1/2" x 11" with 1-inch margins) must be submitted via e-mail: SUBMIT@knowledgefoundation.com no later than May 10, 2014 for inclusion in conference documentation. Additional poster submissions will be accepted until May 25, 2014 but may not be included in conference documentation.

DIMENSIONS of the poster boards are:
