cholera and phages
2014-09-03 02:00:53

Siobhan Gallagher, Tufts University In the battle between our immune systems and cholera bacteria, humans may have an unknown ally in bacteria-killing viruses known as phages. In a new study, researchers from Tufts University, Massachusetts General Hospital, Partners In Health, Haiti’s National Public Health Laboratory, and elsewhere, report that phages can force cholera bacteria to give up their virulence in order to survive. Importantly, the study — published in eLife — found that...

PLOS YbeY is a conserved protein that is present in most bacteria. A study published on June 5th in PLOS Pathogens examines the function of YbeY in the cholera bacterium and reveals critical roles in RNA metabolism in this and other pathogenic bacteria. Graham Walker, from the Massachusetts Institute of Technology, USA, and colleagues previously studied E. coli YbeY and found that it acts as an "RNase"—a protein that deliberately and specifically cuts RNA molecules and thereby...

E-cigarettes Could Boost Resistance Of Drug-resistant Bacteria
2014-05-19 03:28:28

American Thoracic Society Despite being touted by their manufacturers as a healthy alternative to cigarettes, e-cigarettes appear in a laboratory study to increase the virulence of drug- resistant and potentially life-threatening bacteria, while decreasing the ability of human cells to kill these bacteria Researchers at the VA San Diego Healthcare System (VASDHS) and the University of California, San Diego (UCSD), tested the effects of e-cigarette vapor on live methicillin-resistant...

Certain strains of Salmonella bacteria such as Salmonella Typhimurium (S. Typhimurium) are among of the most common causes of food-borne gastroenteritis. Other strains of Salmonella such as S. Typhi are responsible for typhoid fever, which causes 200,000 deaths around the world each year. Ensuring food is clear of contamination, and water is clean are key to reducing the effects Salmonella can have, but we also need more effective ways to combat Salmonella once it's inside our bodies. To...

MRSA in petri dish
2014-04-10 08:11:45

April Flowers for redOrbit.com - Your Universe Online A new technique to predict the toxicity of a MRSA (methicillin-resistant Staphylococcus aureus) infection from its DNA sequence has been developed by a team of researchers led by the Universities of Bath and Exeter. MRSA remains a public health concern among doctors who are trying to find appropriate treatment options. It and other bacterial pathogens are able to cause disease partially because of toxicity, which is the bacterium's...

Scientists Unlock Evolution Of Cholera And Identify The Strain Responsible For Early Pandemics
2014-01-09 12:57:03

McMaster University Working with a nearly 200-year-old sample of preserved intestine, researchers at McMaster University and the University of Sydney have traced the bacterium behind a global cholera pandemic that killed millions – a version of the same bug that continues to strike vulnerable populations in the world's poorest regions. Using sophisticated techniques, the team has mapped the entire genome of the elusive 19th century bacterium. The findings are significant because,...

TB Bacteria Hide Their Identity To Invade Into Deeper Regions Of The Lungs
2013-12-20 14:30:54

University of Washington Cell surface lipids hide molecular patterns that infection-killing cells might recognize as dangerous TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host's body. Details on this finding are reported Dec. 16 in the advanced online edition of the journal...

Novel 3-D Printing Technology Used To Build Homes For Bacteria At Microscopic Level
2013-10-07 16:33:46

University of Texas at Austin By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections. In a recent experiment they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas aeruginosa, a bacteria...

The bacteria Streptococcus pneumoniae harmlessly colonizes the mucous linings of throats and noses in most people, only becoming virulent when they leave those comfortable surroundings and enter the middle ears, lungs or bloodstream. Now, in research published in July in mBio, University at Buffalo researchers reveal how that happens. “We were asking, what is the mechanism behind what makes us sick?” explains Anders P. Hakansson, PhD, assistant professor...

Acinetobacter baumannii is a species of pathogenic bacteria that is resistant to most antibiotics. Some think the disease is killing tens of thousands of U.S. hospital patients each year due to its resistance to drug treatment. It can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body. It forms opportunistic infections including reports of attacking wounded soldiers and is sometimes abbreviated as MDRAB. It is the most relevant human...
