Hints of altruism among bacteria

In the war against antibiotics, bacteria aren't selfish. According to a new report from Howard Hughes Medical Institute (HHMI) researchers, a handful of resistant pathogens can protect an entire colony.Prevailing wisdom held that antibiotic resistance works only on an individual level: a bacterium acquires a genetic mutation that confers protection against a drug, allowing it to survive and reproduce. Eventually, as vulnerable bacteria die, the mutant's stronger progeny repopulate the colony.But the new study, published September 2, 2010, in the journal Nature, reveals that there are also population-wide changes in the bacterial community at work. When faced with an onslaught of antibiotics, resistant Escherichia coli produce?at an energy cost to themselves?a protein that seeps into the communal broth and triggers a slew of protective mechanisms in their non-resistant neighbors.In the past few years, the rise of 'super bugs' such as MRSA (methicillin-resistant Staphylococcus aureus) has had hospitals and medi
