Once sequenced, our assembled genome sequenced can be annotated to identify target genes and compared to a reference genome for similarities such as the case of BLAST, which is used to establish evolutionary relationships between species. The sequences can also be compared for variants. In this report Illumina-based next generation sequencing was used to sequence the genomes of three Staphylococcus aureus strains which are the methicillin resistant strain (MRSA), methicillin sensitive strain (MSSA) and an unknown strain of S. aureus (U). This involved an array of techniques, from the extraction of genomic DNA by way of the QIAGEN DNeasy DNA extraction kit, to quality control of our purified DNA by 1% agarose gel electrophoresis, Nanodrop and Qubit. It then moved on to preparation of DNA libraries from our genomic DNA extract, with the QIAGEN® QIAseq FX DNA Library Kit, from where the libraries went through an Illumina MiSeq sequencer. Raw sequence data was then assembled and analysed with genome annotation tools such as Atermis, Artemis Comparison Tool, WGSA and Abricate. Annotation of our S. aureus species revealed antimicrobial resistance genes. Abricate produced 10 antimicrobial genes for MRSA, 5 for MSSA and 6 for U. Meanwhile Artemis annotation gave 16 antimicrobial resistance genes for MRSA, 13 for MSSA and 14 for U. Information on antibiotic susceptibility of the three bacterial species can then be used to determine the best possible treatment for individuals with S. aureus infections, thus proving that next generation sequencing and genome annotation can serve as an alternative for routine disc antimicrobial susceptibility techniques to diagnose and treat infectious diseases.

But the efficiency of antibiotics is compromised by the growing number of antibiotic-resistant pathogens. Antibiotic resistance, which is implicated in elevated morbidity and mortality rates as well as in the increased treatment costs, is considered to be one of the major global public health threats (www.who.int/drugresistance/en/) and the magnitude of the problem recently prompted a number of international and national bodies to take actions to protect the public (http://ec.europa.eu/dgs/health_consumer/docs/road-map-amr_en.pdf: http://www.who.int/drugresistance/amr_global_action_plan/en/; http://www.whitehouse.gov/sites/default/files/docs/carb_national_strategy.pdf). Understanding the mechanisms by which bacteria successfully defend themselves against the antibiotic assault represent the main theme of this eBook published as a Research Topic in Frontiers in Microbiology, section of Antimicrobials, Resistance, and Chemotherapy. The articles in the eBook update the reader on various aspects and mechanisms of antibiotic resistance. A better understanding of these mechanisms should facilitate the development of means to potentiate the efficacy and increase the lifespan of antibiotics while minimizing the emergence of antibiotic resistance among pathogens.

This report identifies innovative approaches to the development of antimicrobial drugs and vaccines based on a greater understanding of how the human immune system interacts with both good and bad microbes. The report concludes that the development of a single superdrug to fight all infectious agents is unrealistic.

Unnecessary and inappropriate use of antibiotics favours the emergence and spread of resistant bacteria. A crisis has been building up over decades, so that today common and life-threatening infections are becoming difficult or even impossible to treat. It is time to take much stronger action worldwide to avert an ever increasing health and economic burden. A new WHO publication "The evolving threat of antimicrobial resistance--Options for action" describes examples of policy activities that have addressed AMR in different parts of the world. The aim is to raise awareness and to stimulate further coordinated efforts.

These guidelines aim to help preserve the effectiveness of antibiotics that are important for human medicine by reducing their use in animals.

DOWNLOAD EBOOK →The National Strategy for Combating Antibiotic Resistant Bacteria, published in 2014, sets out a plan for government work to mitigate the emergence and spread of resistant bacteria. Direction on the implementation of this strategy is provided in five-year national action plans, the first covering 2015 to 2020, and the second covering 2020 to 2025. Combating Antimicrobial Resistance and Protecting the Miracle of Modern Medicine evaluates progress made against the national strategy. This report discusses ways to improve detection of resistant infections and estimate the risk to human health from environmental sources of resistance. In addition, the report considers the effect of agricultural practices on human and animal health and animal welfare and ways these practices could be improved, and advises on key drugs and diseases for which animal-specific test breakpoints are needed.

Those consequences will multiply if collaborative global action is not taken to address the spread of resistance. Major drivers of antimicrobial resistance in humans have been accelerated by inappropriate antimicrobial prescribing in health care practices; the inappropriate use of antimicrobials in livestock; and the promulgation of antibiotic resistance genes in the environment. To explore the issue of antimicrobial resistance, the Forum of Microbial Threats planned a public workshop. Participants explored issues of antimicrobial resistance through the lens of One Health, which is a collaborative approach of multiple disciplines - working locally, nationally, and globally - for strengthening systems to counter infectious diseases and related issues that threaten human, animal, and environmental health, with an end point of improving global health and achieving gains in development. They also discussed immediate and short-term actions and research needs that will have the greatest effect on reducing antimicrobial resistance, while taking into account the complexities of bridging different sectors and disciplines to address this global threat. This publication summarizes the presentations and discussions from the workshop.
