New approach may render disease-causing staph harmless
Researchers at the University of Illinois helped lead a collaborative effort to uncover a completely new treatment strategy for serious Staphylococcus aureus ("Staph") infections. view more (2008-02-15)
Treatments for urinary infections leave bacteria bald, happy and vulnerable
A different approach to treating urinary tract infections (UTIs) could defeat the bacteria that cause the infections without directly killing them, a strategy that could help slow the growth of antibiotic-resistant infections. view more (2006-12-21)
New research from Rhode Island Hospital may help predict outcomes for stomach cancer patients
Researchers at Rhode Island Hospital have identified two potential molecular markers that may predict outcomes for patients with stomach cancer, one of the most common and fatal cancers worldwide. view more (2008-07-17)
New genomic model defines microbes by diet -- provides tool for tracking environmental change
In line with the U.S. Department of Energy (DOE) interest in characterizing the biotic factors involved in global carbon cycling, the DOE Joint Genome Institute (JGI) characterizes a diverse array of plants, microorganisms, and the communities in which they reside to inform options for reducing and stabilizing atmospheric greenhouse gases. view more (2009-09-08)
Bacterial toxin closes gate on immune response, Penn researchers discover
Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes. view more (2008-02-14)
New bacteria contaminate hairspray
Scientists in Japan have discovered a new species of bacteria that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology. view more (2008-03-10)
New links in the cystic fibrosis chain uncover potential therapeutics
Cystic fibrosis (CF) is an inherited disease caused by mutations in the CFTR gene. Each mutation has number of effects on the cells of the lungs. view more (2007-10-19)
What makes C-Diff superbug deadly?
A major breakthrough about the potentially deadly superbug Clostridium difficile (C-diff) could lead to new ways to combat the bacterium, according to a study to be published March 1 in the journal Nature. view more (2009-03-02)
An Antimicrobial Solution For Blocked Urinary Catheters? (p 1435)
Authors of a research letter in this week's issue of THE LANCET propose a new method for inflating urinary catheters-which could avoid common problems of encrustration and blockage of the catheter. Urinary catheters are usually inflated with water, but this often results in bacterial build-up leading to catheter encrustration and blockage. David... view more... (2003-04-23)
Are microbes the answer to the energy crisis?
The answer to the looming fuel crisis in the 21st century may be found by thinking small, microscopic in fact. Microscopic organisms from bacteria and cyanobacteria, to fungi to microalgae, are biological factories that are proving to efficient sources of inexpensive, environmentally friendly biofuels that can serve as alternatives to oil,... view more...

Home screening kits for common sexually acquired infection
The arrival of home screening kits for one of the most common sexually acquired infections might not be that far off, suggests research in Sexually Transmitted Infections. The bacterium in question is Chlamydia, infection with which can lead to lifelong infertility, because it is often symptomless and may go undetected for many years. view more (2000-02-28)
Researchers Identify Biofilms That Cause Infection
Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their... view more...

Evolution of symbiosis
The aphid Acyrthosiphon pisum depends on a bacterial symbiont, Buchnera aphidicola, for amino acids it can't get from plants. The aphid, in turn, provides the bacterium with energy and carbon as well as shelter inside specialized cells. view more (2007-04-10)
Texas A&M researchers examine 'invading' bacteria in DNA
Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival. view more (2009-06-03)
Pakistan introduces vaccine to prevent top child killer
This month, Pakistan is introducing a new combination vaccine that will protect its children against the bacterium Haemophilus influenzae type b (Hib) and four other common childhood diseases. view more (2008-11-03)
Genes that make bacteria make up their minds
Bacteria are single cell organisms with no nervous system or brain. So how do individual bacterial cells living as part of a complex community called a biofilm "decide" between different physiological processes (such as movement or producing the "glue" that forms the biofilm)? view more (2009-03-30)
Improving the immune system using ‘chatty’ bacteria
Certain helpful bacteria are able to communicate with cells lining the gut causing the production of chemicals that can kill off harmful microbes when they try to invade, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. view more (2002-04-02)
Caltech scientists get detailed glimpse of chemoreceptor architecture in bacterial cells
Using state-of-the-art electron microscopy techniques, a team led by researchers from Caltech has for the first time visualized and described the precise arrangement of chemoreceptors-the receptors that sense and respond to chemical stimuli-in bacteria. view more (2009-09-25)
Figuring out function from bacteria's bewildering forms
The constellation of shapes and sizes among bacteria is as remarkable as it is mysterious. Why should Spirochaeta halophila resemble a bedspring coil, Stella a star and Clostridium cocleatum a partly eaten donut? No one really knows. view more (2006-07-19)
Researchers map how staph infections alter immune system
Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions. view more (2009-07-14)
