Study: Small RNA chains could regulate the genes involved in salmonella's virulence

A series of small RNA fragments are the regulator factors involved in a new control mechanism for salmonella virulence, a pathogenic bacterium which causes bacterial gastroenteritis with a high incidence -more than 100,000 cases per year- in Europe

Mucus appears to protect flu virus when it becomes airborne, shows study

Mucus and other airway secretions that are expelled when a person with the flu coughs or exhales appear to protect the virus when it becomes airborne, regardless of humidity levels, a creative experiment conducted by the University of Pittsburgh and Virginia Tech discovered.

Cancer cells can use lipid molecules as fuel for growth, shows study

Cancer cells can when the blood supply is low use lipid molecules as fuel instead of blood glucose. This has been shown in animal tumor models by researchers at Karolinska Institutet in Sweden in a study published in Cell Metabolism.

New technique provides more direct way to discern what microbes consume

A new technique devised by researchers from North Carolina State University and the University of Calgary provides a more in-depth look at the metabolism and physiology within microbial communities - the microscopic life such as bacteria, viruses and other tiny forms of life within our bodies and throughout nature.

Study: Disease-causing stomach bacterium shuts down energy production in host cells

Researchers report in a new study that the bacterium Helicobacter pylori - a major contributor to gastritis, ulcers and stomach cancer - resists the body's immune defenses by shutting down energy production within the cells of the stomach lining that serve as a barrier to infection.

Malaria-causing parasite seeks refuge inside the liver to replicate and survive

When the malaria-causing Plasmodium parasite first slips into the human bloodstream, injected by the bite of an infected mosquito, it does not immediately target red blood cells.

Antibacterial substance found in toothpaste may fight against life-threatening lung disease

Michigan State University researchers have found that when triclosan, a substance that reduces or prevents bacteria from growing, is combined with an antibiotic called tobramycin, it kills the cells that protect the CF bacteria, known as Pseudomonas aeruginosa, by up to 99.9 percent.

New study aims to turn MRSA’s strength against it

Antibiotic-resistant infections cause more than 30,000 deaths annually in the U.S. alone. The majority of those are caused by methicillin-resistant Staphylococcus aureus, more commonly known as MRSA, which can turn routine medical operations into near-death battles.
