Gram+ve Blood Culture Test also Detects Antimicrobial Resistance
With a single automated test, the Verigene BC-GP test provides fast genus and species level detection for a broad panel of clinically significant gram-positive bacteria. The BC-GP test also detects several crucial markers for antimicrobial resistance, including the mecA, vanA, and vanB genes, which confer resistance to the antibiotics methicillin/oxacillin and vancomycin. Rapid detection of these antimicrobial resistance markers provides vital information for clinicians to determine the best treatment for bloodstream infections.
"With the BC-GP test, patients suspected of deadly infections can now get a first-ever diagnostic tool for detecting disease-causing bacteria while simultaneously determining antibiotic resistance within the critical timeframe for making and adjusting initial treatment,' said William Moffitt, Nanosphere's Chief Executive Officer.
The BC-GP test provides identification of bacteria and antimicrobial resistance genes from gram-positive blood culture bottles within two and a half hours, as compared with current microbiological methods, which can take up to two to three days.
The sample-to-result BC-GP test automates the steps of bacterial DNA extraction and target detection on the Verigene System.
The ease-of-use and fast turnaround time of the BC-GP test allow hospitals of any size to benefit from the speed and accuracy of automated molecular testing. In addition to its gram-positive blood culture test, Nanosphere is currently developing a test for gram-negative blood cultures that will provide genus, species, and resistance detection on the same automated platform. These tests are part of a comprehensive infectious disease test menu, including the multiplexed Verigene RV+ respiratory virus test cleared by the FDA in 2011, as well as tests for C. difficile and a panel of enteric bacterial and viral pathogens that Nanosphere plans to submit for FDA clearance in 2012.
