Executive Summary


FAQ: Human Microbiome, January 2014

FAQMicrobiome

 

The human microbiome, the collection of trillions of microbes living in and on the human body, is not random, and scientists believe that it plays a role in many basic life processes.  As science continues to explore and better understand the identities and activities of the microbial species comprising the human microbiome, microbiologists hope to draw connections between microbiome composition, host genetics, and human health.  FAQ: Human Microbiome addresses this growing area of research.

Microbes in Pipes: The Microbiology of the Water Distribution System, January 2013

mip

 

Non-microbiologists may assume that the goal of water utilities should be the elimination of all microbes from our drinking water. But the water we drink has never been sterile; perfectly safe water contains millions of non-pathogenic microbes in every glassful. Like every other human built environment, the entire water distribution system — every reservoir, every well, every pipe, and every faucet — is home to hundreds or thousands of species of bacteria, algae, invertebrates, and viruses, most of which are completely harmless to humans. In April, 2012, the American Academy of Microbiology convened a colloquium to assess what is known about the microbial inhabitants of the water distribution system and to propose goals for advancing our understanding of these communities in order to enhance the safety of our drinking water and the resilience of our water infrastructure.

Incorporating Microbial Processes into Climate Models, February 2012


Microbes are critical players in every geochemical cycle relevant to climate including carbon, nitrogen, sulfur, and others. The sum total of microbial activity is enormous, but the net effect of microbial activities on the concentration of carbon dioxide and other climate-relevant gases is currently not known. In February of 2011, the American Academy of Microbiology convened a colloquium to discuss how to integrate microbiological processes and climate models. Based on that colloquium, this report examines our current understanding of how microbes influence climate and identifies key biogeochemical processes, heavily influenced by microbes, which offer attractive starting points to begin collaborations between the two fields. The report also recommends changes to data collection and accessibility, improved incentives for interdisciplinary collaborations, and the development of new technologies as important steps. While the challenge of integrating microbes into climate models is great, one thing is certain, microbes are a force in climate change that cannot be ignored.

Microbial Evolution, August 2011

Website-_Microbial_Evolution

 

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.

The Rare Biosphere, August 2011

Rare_Biosphere

 

The microbial world represents the last truly unexplored frontier in the diversity of life on Earth. New environmental sampling technologies have revealed a wealth of rare microbial species in the soil, ocean, even our own bodies that were effectively cloaked from previous sampling methods by more abundant species. Dubbed the rare biosphere, these microbial species, while individually rare, collectively account for more than 75% of the biomass of some microbial communities, yet little is known about them. This rare biosphere represents a treasure trove of genetic novelty that may possess numerous unique bioprocesses and biomaterials. These rare species may play keystone roles in microbial communities and act as a reservoir of genetic diversity. But how can scientists effectively study the rare biosphere? In April 2009 the American Academy of Microbiology convened a colloquium to explore this question. Based on that colloquium, this report analyzes the current state of study of the rare biosphere and identifies where gaps in knowledge exist. The report concludes that the Herculean task of studying the rare biosphere requires an international collaborative effort and additional environmental sampling, coupled with a focus on advancing sequencing and data analysis technologies. With less than 1% of microbial species able to be grown in the laboratory, the prospects of new discoveries in the rare biosphere seem as vast as microbial diversity itself.

FAQ: Microbes and Oil Spills, February 2011

Cover-_FAQ_Oil

 

Is it true that microbes cleaned up the oil spill in the Gulf of Mexico? Can bacteria really “eat” oil, and if so, how? To help clear up the confusion the American Academy of Microbiology has brought together the nation’s leading experts to consider and answer some of the most frequently asked questions regarding microbes and oil spills. This mini-colloquium, the first in a new series of reports designed to provide a rapid response to emerging issues, took place at ASM Headquarters in Washington, DC on October 28, 2010.

Large-Scale Sequencing: The Future of Genomic Sciences? December 2009

Large_Scale

 

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.

Antibiotic Resistance: An Ecological Perspective on an Old Problem, September 2009

antibiotic_resistance.jpg

 

According to the report, it is possible to co-exist with resistance by- developing new strategies to prevent resistance from spreading and, where it already exists, identify the strains we need to protect against; find new ways to treat resistance infections effectively in patients; and manage reservoirs of antibiotic strains in the environment. The report summarizes the current scientific understanding of antibiotic resistance, the scope of the problem, and methods at our disposal for detecting emergence and preventing spread. The knowledge gaps about the prevalence of resistant strains and resistant infections are highlighted as are the unique problems and challenges in developing countries.

The Fungal Kingdom: Diverse and Essential Roles in Earth's Ecosystem, 2008


Prepared by Arturo Casadevall, Joe Heitman, and Merry Buckley.


Fungi can cause a number of life-threatening diseases but they also are becoming increasingly useful to science and manufacturing every year. However, many people, scientists among them, are largely unaware of the roles fungi play in the world around us. Research on fungi and fungal diseases are seriously neglected as a result – a situation with grave negative repercussions for human health, agriculture, and the environment. The Fungal Kingdom explores the roles fungi play in the world around us.
