Book Description
With the expansion of the breeding production scale and the development of the food industry, the prevalence of foodborne pathogens and subsequent problems including food poisoning and antimicrobial resistance (AMR), contribute much to the global disease burden, leading to the serious health hazard and major economic losses around the world, and foodborne disease has become one of the most challenging issues to public health. The most common pathogens spreading foodborne diseases in humans include but are not limited to Salmonella, Campylobacter, Clostridium, Cronobacter, pathogenic Escherichia coli, Listeria monocytogenes, Staphylococcus aureus, Vibrio parahaemolyticus, Bacillus cereus, Yersinia enterocolitica, etc. These pathogens contaminate various types of foods throughout the food chain including cereal, vegetable, fruit, meat, dairy, and aquatic products in entire proceedings from farmland to fork and disseminate AMR and virulence. In this process, some clinically important antimicrobial-resistant pathogens, such as carbapenem-resistant Enterobacteriaceae (CRE), methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), colistin-resistant or tigecycline-resistant bacteria have spread so quickly that they could be found emerging in clinical hospitals, agricultural farmlands, foods, food animals, environments and also humans/animals guts, in the meantime, super-bug foodborne pathogens with high-level AMR or hypervirulence has been disclosed emerging or re-emerging in more and more publications. Omics techniques including genomics, proteomics, transcriptomics, and metabonomics have greatly improved our understanding of the mechanisms of foodborne pathogens in terms of their AMR and pathogenesis. Simultaneously, an integrated multi-disciplinary “One Health” approach has been used for widespread and sustained surveillance of foodborne pathogens, based on a multi-sectoral collaboration framework, to mitigate and prevent the threats of pathogens of animal-, human-, environment- and food- origins. Though a large number of foodborne pathogen isolates were collected with unfolded phenotypic characteristics as the phase goals for surveillance work, it is still far from clearly exploring how many super-bugs there were, why they were so resistant or hypervirulent, where they came from, how they disseminated, how the mechanisms transmitted and evolved, and what the potential hazards were, etc. We need more intensive and compelling evidence, explanation, and interpretation. This Research Topic aims to provide a platform for recent discoveries and the latest progress in detection, mechanism, and dissemination from Omics insights with regards to the emerging or re-emerging foodborne pathogens with high-level AMR (Multi-drug resistant/Extensively-drug resistant/Pan-drug resistant, MDR/XDR/PDR) or hypervirulence, to increase the understanding of these superbugs, to track their sources, to discover the mechanisms that make them super, and to uncover the dissemination along the animal-food-human chain based on big data, and to assess the human health risks by uptaking them. Emergence, mechanism, and dissemination of them via the food chain by using the application of Omics-based technologies would be of particular interest for this topic. This Research Topic welcomes authors worldwide to contribute any article types like Original Research, Review & Mini-Review, Methods, Hypothesis and Theory, and Perspectives related to this topic, especially for some rare or unusual isolates with extreme importance and significance. Themes in the Research Topic include but are not limited to the sub-topics we suggested below: 1. Detection, prevalence, phenotypic characterizations, risk assessment, and regional or long-term surveillance of the “super-bug” foodborne pathogens; 2. Mechanisms (especially novel mechanisms) explanation/exploration or drug target development using Omics-based technologies and bioinformatics analysis; 3. Regionally or global dissemination of “super-bug” foodborne pathogen clones or relevant determinants especially mobile genetic elements (MGEs); 4. Current advances in the novel and instant detection method/models or method comparison report for the pathogenicity phenotype of the foodborne pathogens; 5. Any pathogen/disease prevention control and clinical treatment management developed to oppose the “super-bug” foodborne pathogen, like the gut microbiota approach, etc. Please note that Frontiers in Microbiology does not accept Case Reports, Clinical Trials, and Systematic Reviews, hence Frontiers in Public Health is a better option. Conflict of Interest: Dr. Scott Van Nguyen works for ATCC. All other topic editors declare no conflict of interest.

Book Description
Advances in next-generation sequencing technologies (NGS) are revolutionizing the field of food microbiology. Microbial whole genome sequencing (WGS) can provide identification, characterization, and subtyping of pathogens for epidemiological investigations at a level of precision previously not possible. This allows for connections and source attribution to be inferred between related isolates that may be overlooked by traditional techniques. The archiving and global sharing of genome sequences allow for retrospective analysis of virulence genes, antimicrobial resistance markers, mobile genetic elements and other novel genes. The advent of high-throughput 16S rRNA amplicon sequencing, in combination with the advantages offered by massively parallel second-generation sequencing for metagenomics, enable intensive studies on the microbiomes of food products and the impact of foods on the human microbiome. These studies may one day lead to the development of reliable culture-independent methods for food monitoring and surveillance. Similarly, RNA-seq has provided insights into the transcriptomes and hence the behaviour of bacterial pathogens in food, food processing environments, and in interaction with the host at a resolution previously not achieved through the use of microarrays and/or RT-PCR. The vast un-tapped potential applications of NGS along with its rapidly declining costs, give this technology the ability to contribute significantly to consumer protection, global trade facilitation, and increased food safety and security. Despite the rapid advances, challenges remain. How will NGS data be incorporated into our existing global food safety infrastructure? How will massive NGS data be stored and shared globally? What bioinformatics solutions will be used to analyse and optimise these large data sets? This Research Topic discusses recent advances in the field of food microbiology made possible through the use of NGS.

Book Description
In January of 2015, under the 1st International Caparica Conference in Antibiotic Resistance, a Research Topic entitled: “Surveying Antimicrobial Resistance: Approaches, Issues, and Challenges to overcome”, was published (http://journal.frontiersin.org/researchtopic/3763/surveying-antimicrobial-resistanceapproaches- issues-and-challenges-to-overcome). The problem of antimicrobial resistance (AMR), caused by excessive and inappropriate use of antibiotics, is a public health issue that concerns us all. The introduction of penicillin in the 1940s, the start of the antibiotics era, has been recognized as one of the greatest advances in therapeutic medicine. However, according to the World Health Organization (WHO), AMR infections are now an increasing worldwide public health threat and a post-antibiotic era is imminent, where common infections and minor injuries could be fatal. AMR is a typical ‘One Health’ problem, in which livestock animals and the environment constitute AMR reservoirs and transmission routes to and from the human population. Without effective antimicrobials to counter and prevent infections, other major achievements in modern medicine, such as organ transplantation, cancer chemotherapy and major surgery, risk being compromised. AMR infections in animals have negative outcomes on animal health, welfare, biosecurity and production. In 2006, the ban of growth promoting antibiotics highlighted antibiotic use in animal production as a risk factor in the development of antibiotic resistant bacteria. Bacteria can be transferred to humans via several routes; consumption of animal products, exposure through contact with animals, and the contamination of ground and surface waters by animal waste products. Therefore, it is of utmost importance that antimicrobial use in animals is reduced to a minimum, without compromising animal health and welfare. Mechanisms of bacterial antibiotic resistance are classified according to the types of antibiotic molecules or their targets in the cell. Environmental antibiotic-resistance genes are spread then acquired by clinically relevant microorganisms. Many resistance genes are conveyed into pathogen genomes via mobile genetic elements such as plasmids, transposons or integrons, increasing the propagation of potential resistant pathogens. Substantial progress has already been made in elucidating the basic regulatory networks that endow bacteria with their extraordinary capacity to adapt to a diversity of lifestyles and external stress factors. So how will we face bacteria in the future?

Book Description
Fungal diseases have contributed to death and disability in humans, triggered global wildlife extinctions and population declines, devastated agricultural crops, and altered forest ecosystem dynamics. Despite the extensive influence of fungi on health and economic well-being, the threats posed by emerging fungal pathogens to life on Earth are often underappreciated and poorly understood. On December 14 and 15, 2010, the IOM's Forum on Microbial Threats hosted a public workshop to explore the scientific and policy dimensions associated with the causes and consequences of emerging fungal diseases.

Book Description
The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.
