While the pathogen Chlamydia pneumoniae has been linked to asthma in the past, new research finds over two-thirds of people with severe asthma test positive for Chlamydia-specific antibodies, suggesting this antigen could be a good biomarker for detecting those at risk for asthma. Additional re... Read More

Introduction and uses of culture media for growing pathogenic bacteria and fungi
On the issue of antibiotic-resistant bacteria and animals, the first thing that comes to mind is livestock and other farm-based animals that are regularly fed antibiotics as growth promoters, but they are not the only source of resistance. Participants discuss studies showing that non-farm anim... Read More
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
A number of variables can cause signficant changes in the human microbiome early in life including birth method and antibiotic exposure. Understanding these shifts is important because new research suggests that shifts in the microbiome of infants could make them more prone to gain weight as adu... Read More
Large concentrations bacteria identified in the nuclei of hailstones suggest that airborne microorganisms may be responsibility for the formation of these weather events. Participants will discuss these findings as well as the implications they may have for understanding of the role microbes pl... Read More
Over a year after the largest oil spill in the Gulf of Mexico, scientists are still investigating the role microorganisms play in cleaning up the mess, both on land and at sea. Participants will discuss the latest research, what we have learned and what we still do not know.

The ability of bacteria to be genetically manipulated in a directed way has permitted the application of bacterial metabolism and gene expression to the creation of products useful in a wide variety of domains, including alternative energy generation, novel and manipulatable pathways for antibio...

Clostridium difficile infection is an important cause of intestinal disease, primarily affecting hospitalized patients exposed to antibiotics. Infection has been associated with prolonged hospital stays and excess healthcare expenditures.Recent changes in epidemiology of this disease show a rise... Read More
This animation starts with the explanation of bacterial cell wall synthesis, the process targeted by ß-Lactams.
Structurally, most bacteria consist of a cell membrane surrounded by a cell wall and, for some bacteria, an additional outer layer. Internal to the cell membrane is the cytoplasm whi... Read More
The health of humans, animals, and the environment are inextricably interconnected. Disruption of the environment often creates new niches for the evolution of infectious diseases, and provides opportunities for the transmission of pathogens to animals or humans. The majority of infectious disea... Read More
The NIH Human Microbiome Project has been a 5-year endeavor to produce community resources to support the field of human microbiome research. Although the HMP has already produced hundreds of peer-reviewed publications, in the past week 2 major HMP Consortium papers as well as 20+ companion pap... Read More
Explore Research at the University of Florida: Keith Schneider, an Associate Professor of Food Science and Human Nutrition at the University of Florida, explains what made him want to become a scientist originally, and what he enjoys about his career and research now. Read More
High school students and their teachers participate in a simple activity to demonstrate the interaction between the var antigens malaria parasites display and the patient's immune system. Read More
Leaking septic systems or manure from adjacent rural properties are the two most common sources of fecal contamination of a well. The University of Wisconsin Water Resources Institute is funding a new research project to refine a methodology to determine the source of well water contamination.

Extended spectrum beta-lactamases (ESBL's) are enzymes that enable bacteria to resist multiple antibiotics. In the past few years ESBL-producing enteric bacteria (such as E. coli) have become an increasingly common cause of community acquired infections worldwide. The source of these organisms i...

For a holiday card, my wife and I made a Christmas Tree with bioluminescent ornaments. The video shows how the tree looks in natural light, and then by its own light. The bacterium is Photobacterium leiognathi, isolated by Ned Ruby and Eric Stabb in Hawai'i. This is another example of where mi... Read More
In as little as 100 generations, yeast selected to settle more quickly through a test tube evolved into multicellular, snowflake-like clusters, according to a paper published in Proceedings of the National Academy of Sciences. Over the course of the experiment, the clusters evolved to be larger,... Read More
