Using 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 ...

Protein synthesis, ATP unnecessary for bacterial spore germination

Spores of Bacillus bacteria can survive for years in a dormant state, and then germinate in minutes. But it has long been unclear whether germination required protein synthesis, or cellular energy packets, which are known ...

Genes found in H. pylori that influence biofilm formation

Most bacteria cannot survive in the acidic environment of the human stomach, but Helicobacter pylori, a major cause of ulcers, thrives under such circumstances. Now research has shown that one of that bacterium's regulatory ...

C. difficile needs iron, but too much is hazardous

Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron ...

New light on bacterial microcompartments

Bacteria contain "microcompartments," which are poorly understood organelles that play critical roles in metabolism. Understanding how they work may ultimately enable engineering them for useful applications. In salmonella, ...

Compound from soil microbe inhibits biofilm formation

Researchers have shown that a known antibiotic and antifungal compound produced by a soil microbe can inhibit another species of microbe from forming biofilms—microbial mats that frequently are medically harmful—without ...

Mutant bacteria that keep on growing

The typical Escherichia coli, the laboratory rat of microbiology, is a tiny 1-2 thousandths of a millimeter long. Now, by blocking cell division, two researchers at Concordia University in Montreal have grown E. coli that ...

Enterotoxigenic E. coli worldwide are closely related

The strains of enterotoxigenic Escherichia coli (ETEC) that infect adults and children in Asia, Africa, and the Americas, have notably similar toxins and virulence factors, according to research published ahead of print in ...
