It was hard enough for health officials to track down the source of the original outbreak of Legionnaires' disease, at the old Bellevue Stratford Hotel in Philadelphia, in 1976.
Imagine if the disease had been caused by a moving target.

Whether or not ecological disaster follows the BP spill may hinge on what eats the oil first.
"Right now it's a race between the microbes and the fish," said marine biologist Larry McKinney of Texas A&M University, a specialist in the Gulf of Mexico.
Ideally, microbes will win, transformin... Read More
Two recent studies provide evidence for a new approach to vaccines to prevent infections caused by drug-resistant Staphylococcus aureus -- better known as MRSA – the leading cause of skin and soft tissue, bloodstream and lung infections in the United States. One demonstrates a way to counteract... Read More
The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive -- and thrive -- within the stomach'... Read More
By now many people will be aware of one of this week's topics of conversation, the emergence of the resistance determinant New Delhi metallo-β-lactamase 1 (or NDM-1), which is an enzyme that confers resistance to a group of very useful antibiotics, the carbapenems; it does this by cleaving the a...

Research has shown that bacteria - among the simplest life forms on Earth - have a sense of smell.
Scientists from Newcastle University in the UK have demonstrated that a bacterium commonly found in soil can sniff and react to ammonia in the air.
It was previously thought that this "olfact... Read More
A new drug-resistant "superbug" that originated in South Asia has claimed the life of a Belgian man. It’s the first reported death from bacteria with the New Delhi metallo-lactamase-1 gene,Agence France-Presses reported. The gene, which is found in a number of different bacteria, produces an en...
