Abstract

A new low cost, multi-channel desktop digital instrument was developed which measures bacteria response when exposed to multiple antibiotics vs a control channel with no antibiotic in about an hour by detecting PM noise induced by their mechanical motion when tightly tethered to a resonator. The motivation for this work comes from the approximately 13 million urinary tract infections (UTIs) leading to some 63,000 deaths yearly in the USA and many more worldwide, primarily due to E. Coli and the two-day delay in diagnosing antibiotic resistance. Rapid determination of efficacy could potentially save lives and extend antibiotic lifetimes.
