This chapter presents recent advances in bacteriophage research and their application in the area of food safety. Section 1 describes general facts on phage biology that are relevant to their application for control and detection of bacterial pathogens in food and environmental samples. Section 2 summarizes the recently acquired data on application of bacteriophages to control growth of bacterial pathogens and spoilage organisms in food and food-processing environment. Section 3 deals with application of bacteriophages for detection and identification of bacterial pathogens. Advantages of bacteriophage-based methods are presented and their shortcomings are discussed. The chapter is intended for food scientist and food product developers, and people in food inspection and health agencies with the ultimate goal to attract their attention to the new developing technology that has a tremendous potential in providing means for producing wholesome and safe food.

Reports on pathogen detection have usually focused on the following methodologies such as traditional culture collection (Reissbrodt, 2004; Velusamy et al., 2010), genetic approaches based on polymerase chain reaction (PCR) (Bennett et al., 1998; Gallegos-Robles et al., 2009; Malorny et al., 2003), and immunological methods (Cho et al., 2014; Pandey et al., 2014), although other methods such as scattering spectroscopy (Banada et al., 2009; Bhunia, 2008; Rajwa et al., 2010) and phage-based detection (Brovko et al., 2012; Goodridge et al., 1999; Smartt et al., 2012) have also been used. Methods such as colony counting and biochemical methods are effective and reliable and are the gold standard, but takes several days and are accompanied with laborious steps. "

    ABSTRACT: To date most LF-ICA format for pathogen detection is based on generating color signals from gold nanoparticle (AuNP) tracers that are perceivable by naked eye but often these methods exhibit sensitivity lower than those associated with the conventional enzyme-based immunological methods or mandated by the regulatory guidelines. By developing AuNP avidin-biotin constructs in which a number of enzymes can be labeled we report on an enhanced LF-ICA system to detect pathogens at very low levels. With this approach we show that as low as 100CFU/mL of Escherichia coli O157:H7 can be detected, indicating that the limit of detection can be increased by about 1000-fold due to our signal amplification approach. In addition, extensive cross-reactivity experiments were conducted (19 different organisms were used) to test and successfully validate the specificity of the assay. Semi-quantitative analysis can be performed using signal intensities which were correlated with the target pathogen concentrations for calibration by image processing. Copyright © 2015 Elsevier B.V.

    ABSTRACT: The first studies involving phage dating from the early nineteenth century. In the last three decades these studies were intensified, mainly because of the emergence of antibiotic-resistant bacterial strains. Since then, the wide and diversity of phage species became evident. It is estimated that there are 10 31 particles and 10 8 different species of phages dispersed in the biosphere, which highlights their importance in ecosystems on the planet. These data generates the need for an efficient phage classification system. Classically, the phages have been classified according to their structure, type of genetic material (DNA or RNA), host range and infection cycle. Additionally, molecular techniques such as pattern of enzymatic restriction of the DNA, profile of structural proteins, and more recently gene sequencing have been increasingly employed for

    ABSTRACT: Enteric infections account for high morbidity and mortality and are considered to be the fifth leading cause of death at all ages worldwide. Seventy percent of all enteric infections are foodborne. Thus significant efforts have been directed toward the detection, control and prevention of foodborne diseases. Many antimicrobials including antibiotics have been used for their control and prevention. However, probiotics offer a potential alternative intervention strategy owing to their general health beneficial properties and inhibitory effects against foodborne pathogens. Often, antimicrobial probiotic action is non-specific and non-discriminatory or may be ineffective. In such cases, bioengineered probiotics expressing foreign gene products to achieve specific function is highly desirable. In this review we summarize the strategic development of recombinant bioengineered probiotics to control enteric infections, and to examine how scientific advancements in the human microbiome and their immunomodulatory effects help develop such novel and safe bioengineered probiotics.
