Microbiome Monday: The Ecology of a Killer Microbe
Curators DeSalle and Perkins explore the ecology and life cycle of the killer microbe Legionella.
Humans are just a speck in a massively bacterial world. Living in and on us, microbes make up 70 to 90 percent of all cells in our bodies—our microbiome—and our health depends upon them. What makes some of these bacteria benign and others cause disease, like antibiotic-resistant superbugs? What are the health effects of antibiotic overuse, and how can we restore depleted microbiomes? What can we learn from sequencing the DNA of these extraordinarily diverse ecosystems, and from the microorganism communities around us—our macrobiomes? The answers have fascinating and critically important implications for how we track pathogens, prevent disease, and stay healthy.

Microbiologist Martin Blaser discusses how changes in the human microbiome - for example, through the overuse of antibiotics and hand sanitizers - may be contributing to an increase in chronic conditions such as obesity.
Microbiology researchers recently proved that populations of microbes living in and on the human body affect their hosts' health. In this podcast, physician and microbiologist Martin Blaser discusses how changes in the human microbiome - for example, through the overuse of antibiotics and hand sanitizers - may be contributing to an increase in chronic conditions including obesity, allergic disorders, and diabetes.
A superbug’s resistance is linked to antibiotics in livestock feed.
Humans are hosts to trillions of microbes, most of which are harmless or even beneficial. But a new study shows how one bacterium traveled from humans to farm animals and back to humans, developing resistance to antibiotics along the way. Identifying the evolutionary processes of disease agents that transfer between species may help scientists determine how to prevent and treat emerging diseases.
Explore how changes in the human microbiome may be contributing to an increase in obesity and other chronic conditions.
Each one of us is an ecosystem with an estimated one trillion other microscopic organisms living in and on us at any given time. And these organisms, collectively known as our microbiome, contain about 300 times the number of genes that our own genomes express. Explore how changes in the human microbiome may be contributing to an increase in obesity and other chronic conditions.

Preliminary results are in from a Museum study of microbiome samples from individuals from more than 50 countries.
An initial sampling period conducted at the Museum this summer has provided the Healthy Human Microbiome Project with microbiome samples from individuals from more than 50 countries—and some fascinating preliminary results.
See how the Human Microbiome Project is shedding light on the microbes that live inside us.
The Human Microbiome Project, an initiative of the National Institutes of Health, is cataloguing trillions of microbes that live within the human body. Researchers are focusing on numerous body regionsincluding the skin, hair, mouth, nose, gut and urogenital tract to identify and study the vast number of microbial species, mostly bacteria, that live there. This project and related research efforts around the world are advancing our understanding of how humans co-evolved with these resident species and how we depend on them to stay healthy. This Human Bulletin presents some fascinating examples of the human microbiome.
To understand how everyday microbes can change so dramatically, laboratories are investigating how bacterial communities exchange genetic information in the environments we share.
The bacteria Staphylococcus aureus is a benign resident of the human microbiome. But in the last 15 years, a strain of it has evolved to become a major public health problem. To understand how everyday microbes can change so dramatically, laboratories are investigating how bacterial communities exchange genetic information in the environments we share.
What does the genetic fingerprint of New York City look like? Microbiome researcher Chris Mason is trying to find out.
It’s a question that’s plagued every New York commuter: “Why is this subway pole sticky?” Weill Cornell Medical College Assistant Professor of Genetics Chris Mason, who spoke at February’s SciCafe may soon have a very detailed answer.
The first in a series of weekly primers on the microbiome and the research surrounding it.
The first in a series of weekly primers on the microbiome comes from Dr. Martin Blaser, the Muriel and George Singer Professor of Translational Medicine and a Professor of Microbiology at New York University, and also the author of Missing Microbes: How the Overuse of Antibiotics is Fueling Our Modern Plague.
Curators Rob DeSalle and Susan Perkins answer the internet's most pressing questions on microbes.
Have you ever wondered if microbes are… animals? Bacteria? Consumers? Thanks to Google, we know you have! We found the most commonly searched microbial questions, from A to Z, and put them to Rob DeSalle and Susan Perkins, curators of the Museum's exhibition about the human microbiome.
Some microbes make us sick. Most are helpful. Play this game to find out more about them.
Our health depends on trillions of microbes living in our bodies.
From the surface of our skin to deep inside our gut, humans are teeming with microbes. The trillions of microorganisms that inhabit humans make up 1 to 3 percent of our total mass and play a vital role in our everyday functions and overall health. Deciphering the complexity of the human microbiome will help determine new methods for health management and treatment of disease.
These curriculum materials show practicing physicians and infectious disease specialists studying the origins and impacts of pathogens.
Over the past 15 years, methicillin-resistant Staphylococcus aureus (MRSA) has become a major public health problem. This series of articles and videos show practicing physicians and infectious disease specialists studying the impacts that pathogens are having in hospitals. The case follows these scientists into the laboratory to see what genomic sequencing is revealing about the origins of pathogenicity and its future course.
Bacterial infusions can heal gut microbe imbalances.
Interactions between many species of bacteria create a healthy environment in the human stomach and intestines. But when medicines like antibiotics upset the normal microbial balance, certain harmful species can multiply and thrive, causing infections that are difficult to cure. Scientists are successfully treating a type of digestive disorder using transplanted microbes from donors with healthy digestive systems to reestablish microbial diversity.
Dr. Maria Gloria Dominguez-Bello at New York University is working to find out how modern Western lifestyles are affecting the development of our microbiomes.

How can the influenza virus travel around the world? Find out in this quizzy story!
Just like you, your house or apartment has its own microbiome—a unique, invisible population of bacteria, fungi, and viruses living within it.
By studying fossilized bacteria in plaque from ancient teeth, scientists link carbohydrates and highly processed foods to the rise of two species of harmful oral bacteria.
When humans became more dependent on carbohydrates, the diversity in our oral microbiome suffered. Farming brought significant dietary changes to human societies worldwide, causing microbial populations in human mouths to change dramatically. By studying fossilized bacteria in plaque from ancient teeth, scientists link carbohydrates and highly processed foods to the rise of two species of harmful oral bacteria that increase our susceptibility to cavities and gum disease.
Gut microbe study reveals that ancient diets suited our bodies better.
Italian scientists report that people in Western countries lack the diversity of stomach bacteria found in rural villagers in Africa. The implication is that our bodies are better suited to the diets of our ancestors than the modern Western diet.
In his SciCafe, genetist Chris Mason talked about the importance of understanding not just our microbiome, but our macro biome as well.
Preview description: Every year, scientists are learning more and more about the human microbiome, the collection of microorganisms and bacteria that live in and on our bodies. But what about our “macrobiomes” – the microorganism communities that live in our environments? In this SciCafe, geneticist Chris Mason talks about his desire to get the gene sequence of every thing and place he sees, and the ways in which we can use the information we get from our bodies as well as our environments.
