Now barcodes to Help Doctors Diagnose Infections Faster
Researchers at the University of Maryland, Baltimore (UMB) have identified a potential way to more quickly diagnose infections by developing a "barcode" for each pathogen strain.

In 2014, the researchers created a startup to commercialize the technology. The company, called Pataigin, hit a key point in further developing the technology for hospital use by inking a licensing deal for patents and technology associated with the disease. (Along with UMB, the University of Washington co-owns of one of the patents).

The technology behind Pataigin, which is named after the Irish word for "pathogen," was developed in Baltimore labs by company cofounders Robert Ernst of the university's School of Dentistry, and David Goodlett of the School of Pharmacy.

Each disease-causing agent has a molecule called a lipid on its outer membrane that is unique in each type of bacteria. The researchers created a library of "barcodes" for each lipid with key identifying information. As a result, lab staff can use a chemical analysis known as mass spectrometry to identify the disease based on the barcode.

"We see the potential here for a diagnostic that can ultimately be effective enough for routine clinical use for appropriate patients that is going to offer superior performance capability to what people get now," said Nilsson, who has led software companies including Deurion, which has a presence in Baltimore and developed mass spectrometry software. The analysis can determine whether the diseases can be treated.

The technique could save people from having to undergo a potentially harsh treatment. Nilsson said. With the money spent on treatments that are not properly diagnosed, he also believes there is also an opportunity to save money in the healthcare system.

The licensing deal provides the company with exclusive rights to the technology, so it can begin to ramp up work.

According to UM Ventures' Phil Robilotto, the Pataigin deal is the tenth such deal the university's startup-backing arm has completed since October 2014."This is our sixth in the last six months," he said, calling the volume "a big shift for us."
