A fast and reliable detection and identification of microorganisms is crucial in environmental science, for food quality as well as medical diagnosis. In these fields, all types of Raman spectroscopy are gaining more and more importance during the last years. The review provides an extensive overview of recent research, technical expertise, and scientific findings based on Raman spectroscopic detection and identification of microorganisms within the years 2010 and 2015, demonstrating the diverse capability of Raman spectroscopy as a modern analytical tool. Raman spectroscopy distinguishes itself from other currently applied techniques by its easy application at low cost, its high speed of analysis, and its broad information content on both the chemical composition and the structure of biomolecules within the microorganisms. Slight chances in the chemical composition of microorganisms can be monitored by means of Raman spectroscopy and used to differentiate genera, species, or even strains. Detection of pathogens is possible from complex matrices, such as soil, food, and body fluids. Further, spectroscopic studies of host–pathogen interactions are addressed as well as the effect of antibiotics on bacteria. Copyright © 2015 John Wiley & Sons, Ltd.

“…Singleplex and multiplex detection of E. coli, S. aureus, Campylobacter, Listeria, and Bacillus anthracis spores coupled with immunomagnetic separation (IMS), microfluidics, and filtration have been reported (19,43,77,104,121,134). Detection has been evaluated in some food matrices, including ground beef, peanut butter, apple juice, and orange juice (19,43,77,121). Representative LODs were 15 to 35 CFU/ml in pure culture (134) and 10 2 CFU/ml in apple juice (77) without enrichment and 10 CFU/ml in ground beef after 2 h of enrichment (19).…”

Bacterial pathogens are one of the leading causes of food safety incidents and product recalls worldwide. Timely detection and identification of microbial contamination in agricultural and food products is crucial for disease prevention and outbreak investigation. In efforts to improve and/or replace time-consuming and laborious "gold standards" for pathogen detection, numerous alternative rapid methods have been proposed in the past 15 years, with a trend toward incorporating nanotechnology and nanomaterials in food pathogen detection. This article is a review of the use of nanotechnology in various detection and sample preparation techniques and advancements in nanotechnology applications in food matrices. Some practical considerations in nanobioassay design are discussed, and the gaps between research status quo and market demands are identified.

“…For example, Ma et al (2014) described the use of the paper clip immunoassay that incorporated gold nanoparticles that can quantify bacteria in water samples (Ma et al 2014). Another example is the use of magnetite-gold nanoparticles bound to E. coli O157:H7-specific antibodies which are used in combination with immunomagnetic separation (IMS) methods and surfaceenhanced Raman spectroscopy for the detection of E. coli O157:H7 in apple juice (Najafi et al 2014).…”

Pages: vi + 258 ISBN: Book: 978-1-910190-77-7. Ebook: 978-1-910190-78-4 £159, $319 Published by: Caister Academic Press www.caister.com Escherichia coli is an important member of the normal healthy microbiome of humans and other mammals. In addition, some strains are thought to be probiotic, and therefore beneficial to the host. However, other strains of E. coli have evolved into highly versatile, and frequently deadly, pathogens, the resultant diseases causing significant economic loss and public health burdens worldwide. Recent studies have shown that the E. coli genome has a high plasticity allowing it to adapt to new niches and survive in stressful conditions and to evolve into new hybrid strains with shared genes, including virulence genes. Omics and whole genome sequencing approaches have transformed research in this field allowing fascinating new insights into the molecular and cellular biology of the bacterium thus paving the way for the development of novel therapeutic strategies. Under the expert guidance of the editors in this book, renowned international authors provide timely and up-to-date reviews of current cutting-edge E. coli omics, molecular-and cellular-biology research. Topics range from E. coli genome plasticity and evolution to the application of omics technologies for in silico modeling to understand stress-triggered physiological responses. This authoritative volume is essential reading for scientists, both experts and students, working on pathogenic E. coli in academia, government, and biotechnology companies. It is also a must-read for anyone with an interest in bacterial pathogenesis and an important acquisition for all microbiology libraries.
