Biosensor that detects antibiotic resistance brings us one step closer to fighting superbugs
Date:5/8/2013

mmon antibiotics. However, variations of the staph bacteria can turn deadly when infecting immune-compromised patients or internal organs like lungs and the respiratory tract. The disease is of particular concern to hospitals, prisons, and branches of the military, where individuals are at risk for infection from unhygienic close quarters.

"In our method, we can determine bacterial antibiotic resistance in 10-12 minutes, while other methods take hours," Dr. Vodyanoy explains. Alternative methods used to detect antibiotic resistance need time-intensive purification steps before multi-hour sequencing protocols. "We envision a future where clinicians do tests with real blood or saliva samples. The virus is completely benign to humans, and we hope to use it to make antimicrobial surfaces and glassware that kill the bacteria."

"Our technique is complex and involves many steps and disciplines. It is very difficult to visualize when you read a paper, and we felt it would be very beneficial and educational to publish [in JoVE]," Dr. Vodyanoy says of publishing in the world's first video journal. "We are interested in someone else reproducing our results; this technology can be used on a larger scale and for antibiotic resistance other than Staphylococcus."
