Pneumatosis cystoids intestinalis after fluorouracil chemotherapy
The mechanism of pneumatosis cystoids intestinalis (PCI) is unclear. The mechanical and bacterial factors are most predominant causes of PCI. view more (2008-09-18)
Theory shows mechanism behind delayed development of antibiotic resistance
Inhibiting the "drug efflux pumps" in bacteria, which function as their defence mechanisms against antibiotics, can mask the effect of mutations that have led to resistance in the form of low-affinity drug binding to target molecules in the cell. view more (2009-05-06)
Friendly bacteria in alcoholic milkshake could fight food allergies
Feeding babies alcoholic milk may help to protect against some food allergies. Kefir, a traditional fermented drink, is consumed in Eastern Europe as a health food, and is often used to wean babies, as it is easily digested. view more (2006-10-16)
Most widely used organic pesticide requires help to kill
The world's most widely used organic insecticide, a plucky bacterium known as Bacillus thuringiensis or Bt for short, requires the assistance of other microbes to perform its insect-slaying work, a new study has found. view more (2006-09-26)
Helping the aged gut replace good bacteria may reduce cancer risk
Eating certain foods can increase the number of protective microbes in the gut. These bacteria help prevent food poisoning and can reduce levels of some toxic chemicals that may cause cancer, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. "We have... view more... (2002-04-02)
Bacteria pack their own demise
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. view more (2009-07-31)
Fewer deaths with preventive antibiotic use
Administering antibiotics as a preventive measure to patients in intensive care units (ICUs) increases their chances of survival. This has emerged from a study involving nearly sixthousand Dutch patients in thirteen hospitals. view more (2009-01-05)
Researchers track Lyme disease spirochetes
Microbiologists at the University of Calgary have demonstrated the first direct visualization of the dissemination of Borrelia burgdorferi, the bacterium that causes Lyme disease. view more (2008-06-20)
Stem cells and cancer: cancer pathways that also control the adult stem cell population
Speaking today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Alan Clarke from Cardiff University describes his work to investigate a mechanism that normally drives adult stem cells to repair the intestine. view more (2008-04-10)
Tuberculosis drug shows promise against latent bacteria
A new study has shown that an investigational drug (R207910, currently in clinical trials against multi-drug resistant tuberculosis strains) is quite effective at killing latent bacteria. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent disease. view more (2008-09-15)
A molecule impedes the destruction of the 'Brucella' bacteria
Research carried out with the participation of the University of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). view more (2005-06-15)
Contaminated soil pollution solution: herbicide eating bugs
Cancer-causing soil pollution from herbicide residues may be avoided in future thanks to researchers from Exeter University, who have identified bacteria which can break down a widely used toxic chemical, scientists will announce tomorrow (Thursday, 09 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College... view more...

Bacterium manipulates the human defence system: The Borrelia bacterium is a master of disguise
Borrelia bacteria are capable of masking themselves in the human body and deceiving the immune defence system. In this way they can hide in the human organism even for periods of years. In their recent studies Professor Seppo Meri and his team have managed to trace the evasive movements of the Borrelia bacterium in the body. Their work is part of... view more... (2005-05-20)
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 life found in ancient tombs
Life has been discovered in the barren depths of Rome's ancient tombs, proving catacombs are not just a resting place for the dead. The two new species of bacteria found growing on the walls of the Roman tombs may help protect our cultural heritage monuments. view more (2008-09-25)
Suntans are bad for bacteria too! Exposure to UV irradiation kills off harmful bacteria in food
Research news from the Journal of the Science of Food and Agriculture 15 December 2003: The presence of E.coli bacteria, found in foods such as egg white and apple juice, is a major public health concern. The bacteria have, in the past, been inactivated by heat pasteurisation -- which can affect flavour and consistency. New evidence published in... view more... (2003-12-15)
From lung to gut - the Wnt signaling pathway transforms cell fate
Researchers have uncovered a cellular mechanism that can alter the fate of progenitor cells that normally generate the lung, causing them to create gut cells instead. The findings, which are published this week in the top-tier Open Access journal, Journal of Biology, could help researchers hoping to use adult stem cells for therapeutic purposes.... view more...

Vaccine could cut complications after surgery
A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. Dr Elliott Bennett-Guerrero, Chief of Cardiac Anesthesia at Columbia... view more... (2002-04-03)
Different strategies underlie the ecology of microbial invasions
Infectious disease can play a key role in mediating the outcome of competition between rival groups, as seen in the effects of disease-bearing conquistadors in the New World-or, on a much smaller ecological scale, the ability of bacteria to spread their viruses to competing bacteria. view more (2006-10-24)
New bacterial species found in human mouth
Scientists have discovered a new species of bacteria in the mouth. The finding could help scientists to understand tooth decay and gum disease and may lead to better treatments, according to research published in the August issue of the International Journal of Systematic and Evolutionary Microbiology. view more (2008-08-11)
