The results reported in this manuscript, authored by leading experts in microbiology and molecular diagnostics, demonstrate the performance of the Verigene BC-GP Test in simultaneously detecting and identifying Staphylococcus aureus and 11 other gram-positive bacterial gene targets known to cause bloodstream infections and three genetic resistance determinants (the mecA, vanA, and vanB genes), directly from positive blood culture media. In addition, a retrospective analysis of turn-around time found that the Verigene BC-GP Test identified methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) species -- two especially deadly causes of bloodstream infection -- an average of 42 hours faster than reference methods.
"The study concluded that the Verigene BC-GP Test is capable of detecting the leading causes of gram-positive bacterial bloodstream infections as well as genetic markers for methicillin resistance in Staphylococcus aureus and vancomycin resistant Enterococcus directly from positive blood cultures, and has the potential to markedly reduce turn-around time for reporting," said Dr. Nathan A. Ledeboer, Associate Professor of Pathology at the Medical College of Wisconsin.
"We are very pleased these study results have been published in PLOS Medicine, an evidence-based journal that focuses on diseases that cause the greatest healthcare and economic burden worldwide," said Michael McGarrity, Nanosphere's president and chief executive officer. "These results are significant as they further validate the compelling value of the Verigene BC-GP Test in enabling rapid analysis and reporting of this time-critical, clinically actionable information to physicians. Our tests have been designed based on comprehensive market feedback to work hand-in-hand with laboratory best practices to provide physicians with the optimal set of results for clinical decision making. Furthermore, we believe the Verigene System's ability to directly detect a comprehensive panel of bacterial DNA targets without the use of PCR is ideally and uniquely suited to the challenge of accurately identifying organisms in blood culture media."
