Imaging Technique Aids Fight Against Chronic Infections

A clever new imaging technique discovered at the Univ. of California, Berkeley, reveals a possible plan of attack for many bacterial diseases, such as cholera, lung infections in cystic fibrosis patients and even chronic sinusitis, that form biofilms that make them resistant to antibiotics.

By devising a new fluorescent labeling strategy and employing super-resolution light microscopy, the researchers were able to examine the structure of sticky plaques called bacterial biofilms that make these infections so tenacious. They also identified genetic targets for potential drugs that could break up the bacterial community and expose the bugs to the killing power of antibiotics.
