Special Issue Information

Dear Colleagues,

Traditional enrichment culture combined with differential and selective plating serve as gold standards for the detection and identification of foodborne bacterial pathogens. Although accurate and sensitive, culture-based methods are labor intensive and time consuming with the results often taking from days to weeks. There is a desire to replace these methods with “rapid methods” that typically employ highly sensitive and fast biosensor-based analysis. However, creative thought and/or diligent empirical effort are required to introduce paradigm shifts in the generation of rapid methods capable of replacing culture-based methods if the need for comparable sensitivity and accuracy is warranted.  Therefore, this Special Issue will showcase contributions ranging from novel sample preparative techniques (like advances in filtration, centrifugation, chemical or particle-based separation, etc.) for the selective, rapid, efficient, and/or quantitative recovery and concentration of targeted bacterial analytes to the development and/or improvement of rapid biosensor-based detection and/or identification platforms (e.g., PCR, phage, immunoassays, optical imaging, luminescence, strip assays, flow cytometry, sequencing, etc.). A further challenge is the determination of live vs. dead organisms. Advances in this field are expected to impact the food production/testing industry and regulatory agencies alike.

Original and review papers dealing with all aspects of “Advances in Foodborne Pathogen Analysis” are welcome for inclusion in this Special Issue of Foods. Reports will focus on the following areas: development and/or improvement of rapid methods for the detection and/or identification of foodborne pathogens (methods, reagents, instrumentation); sample preparation techniques for the rapid and quantitative concentration of targeted microbes in food matrices; new approaches for determining or characterizing pathogen activity, metabolic state or viability.

Biofilms enable the persistence of pathogens in food processing environments. Sanitizing agents are needed that are effective against pathogens entrapped in biofilms that are more difficult to inactivate than planktonic cells that are displaced and found on equipment surfaces. We examined conditions to develop, analyze, and enumerate the enhanced biofilms of three different foodborne pathogens assisted by fluorescence adherence assay and enzymatic detachment. We compared three different isomeric forms of fluorescent substrates that are readily taken up by bacterial cells based on carboxy-fluorescein diacetate (5-CFDA, 5,6-CFDA, 5,6-CFDA, SE). Biofilm-forming strains of Escherichia coli O157:H7 F4546 and Salmonella Montevideo FSIS 051 were identified using a microplate fluorescence assay defined previously for L. monocytogenes. Adherence levels were determined by differences in relative fluorescence units (RFU) as well as recovered bacterial cells. Multiple hydrolytic enzymes were examined for each representative pathogen for the most suitable enzyme for detachment and enumeration to confirm adherence data obtained by fluorescence assay. Cultures were grown overnight in microplates, incubated, washed and replenished with fresh sterile growth medium; this cycle was repeated for seven consecutive days to enrich for robust biofilms. Treatments were performed in triplicate and compared by one-way analysis of variance (ANOVA) to determine significant differences (p < 0.05). Full article
