Next-generation sequencing (NGS) has the capacity to provide crucial clinical benefits in patient care, patient outcomes, and public health, however, clinical laboratories must find ways to overcome operational, technical, regulatory, and strategic challenges in order to effectively employ NGS-based diagnostic tests. The Academy convened a colloquium on this topic in April 2015. Beyond the potential lifesaving impact of NGS methodologies, the report examines the main deterrents and shortcomings of the technology such as the data analysis and management pipelines, regulatory concerns and reimbursement issues, and the creation and maintenance of curated and secure databases. The report, titled Applications of Clinical Microbial Next-Generation Sequencing provides recommendations and suggestions for combating these current limitations to implementing NGS in clinical settings.
Bacteria and viruses are not always categorized as harmful microorganisms. In fact, these groups of microbes can be beneficial and can actively participate in many biological processes. With the perception of microorganisms being our partners, research is now being conducted to use microbes to treat disease and enhance human health. Some viruses and species of bacteria can be targeted to kill cancer cells while others can be deployed to replicate in and kill tumors. The Academy convened a colloquium in April 2014 in San Diego, CA to discuss the vast potential of microbes as supplements to existing therapies against infectious and chronic diseases. The product of those discussions was the full report, Harnessing the Power of Microbes as Therapeutics: Bugs as Drugs.
Concerned about antibiotic resistance? What if an insect pest becomes desensitized to the protective chemicals applied to crops? All kinds of living organisms have evolved mechanisms of resistance against the chemicals designed to control them – from bacteria, viruses, cancer cells to weeds. In the Academy of Microbiology’s newest, free report, explore the Darwinian principles underlying the evolution of resistance in these different biological communities and learn how experts in these fields have developed potentially discipline-spanning strategies of combatting them.
News headlines often paint E. coli as a vicious bacterium, capable of causing disease and death to those unfortunate enough to ingest it. But that is only a tiny minority of E. coli, and a very small part of the story of this remarkable bacterium; its relationship to human health and the food we eat is much more complex. Not all E. coli are bad - in fact most are not - and some are even beneficial. On September 1st 2011, the American Academy of Microbiology convened an expert panel of microbiologists, food safety experts, and bacteriologists to develop a more accurate picture of this often maligned bacterium. This report, the product of that meeting, tells the larger story of E. coli: its role in human health, in food, and even in our understanding of our own biology.
It has been over 150 years since the publication of On the Origin of Species, Charles Darwin’s landmark book based on his observations of animals in the Galapagos Islands. The two core principles he described in his work, descent with modification and natural selection, have helped us understand life’s tremendous diversity. But how do these same principles pertain to the microbial world that Darwin could not see? In 2009 the American Academy of Microbiology convened a colloquium in the Galapagos Islands to address this question. Based on that colloquium, this report summarizes the unique challenges posed by microbes, like vast evolutionary time scale, genetic promiscuity and rapid division, which complicate understanding microbial evolution. It also identifies areas of research and education where more information is needed to overcome these challenges. The report concludes that due to the power of microbes as model systems, tools in biotechnology, and drivers in biogeochemical and climate cycles, understanding microbial evolution may give us more than just the ability to understand microbial diversity; it will help understand the world around us.
Scientists can gain insights into new ways to use microorganisms in medicine and manufacturing through a coordinated large-scale effort to sequence the genomes of not just individual microorganisms but entire ecosystems, according to a new report from the American Academy of Microbiology that outlines recommendations for this massive effort. The report, “Large-Scale Sequencing: The Future of Genomic Sciences?” is based on a colloquium convened by the Academy in September 2008. The report outlines recommendations for large-scale microbial sequencing efforts directed toward cultivated isolates and single cells, as well as a community-scale approach to characterize a set of defined ecosystems of varying complexity.

A new report, released by the American Academy of Microbiology, focuses on how until a decade ago, scientists categorized microorganisms almost exclusively by their physical characteristics: how they looked, what they ate, and the by-products they produced. With the advent of genomic sequencing and genetic analysis in the 1990s, our understanding of the relationships between different microorganisms fundamentally changed. In light of this new knowledge, what exactly is the definition of a microbial species, and how should microbiologists be categorizing microorganisms? These questions are the focus of this new report.

This report details the continued work in genome annotation that will likely lead to new applications and progress in healthcare, bio-defense, energy, the environment, and agriculture. The report also discusses the critical challenges and ways to accelerate progress in the field of genome annotation.
