Data Show “Super Bug” Surveillance System Can Identify Potential Outbreaks in Hospitals and Improve Infection Control

OpGen, Inc. (NASDAQ: OPGN), an early-stage commercial molecular testing and bioinformatics company, today announced that new data from a study with its Acuitas® Resistome Test were presented on October 10 as an oral abstract at IDWeek 2015 by Michael Lin, M.D., M.P.H., an infectious disease physician and assistant professor of medicine at Rush University Medical Center in Chicago. The conference was held October 7 to 11 in San Diego. Dr. Lin and fellow researchers demonstrated how an Acuitas Resistome-based surveillance system can identify potential outbreaks to improve infection control, underscoring the need for healthcare facilities to implement use of molecular-based surveillance systems to detect potential outbreaks that may be caused by multidrug-resistant organisms (MDROs). The research was conducted under the support of the CDC Prevention Epicenters Program and affiliated with the REALM project, a multi-hospital voluntary surveillance network for monitoring multidrug-resistant organisms among Chicago hospital intensive care units and long-term acute care hospitals.

“Since KPC-producing Enterobacteriaceae can carry multiple beta-lactamase genes, beta-lactamase resistome types can be markers indicating how strains are related, and detect a potential outbreak,” said Dr. Lin. “Resistant bacteria typically affect the sickest patients, and accurate and early surveillance data is a key part of our efforts in the Chicago area to successfully manage infections and prevent outbreaks.”

In the study, investigators used OpGen’s test to analyze 363 KPC-producing Enterobacteriaceae culture isolates recovered from 77 distinct hospital-point prevalence rectal culture surveys in the Chicago region from 2010 to 2014. The test discriminated two dominant types in the region and elucidated the facility clustering of minority types, suggesting its utility as an effective infection-control tool.

“The research results from this study with the REALM project and those from our other Acuitas MDRO Gene Test studies presented as posters at IDWeek 2015 show how important it is for hospitals, healthcare systems and public health agencies to develop ways to quickly and accurately detect MDROs using comprehensive genetic analysis and bioinformatics,” said Kevin Krenitsky, M.D., OpGen President.

“We are excited that our data demonstrate how the Acuitas suite of products can fit into programs aimed at improving the ability to rapidly identify MDRO threats, prevent outbreaks, and reduce the incidence of antibiotic resistant infections. These results provide important support to our sales team as we work to cross sell these products into our existing QuickFISH™ customer accounts.”

About MDROs
Multidrug-resistant organisms (MDROs) are common bacteria that have developed resistance to multiple classes of antibiotics. They are a leading cause of hospital-acquired infections and are associated with an increase in morbidity and mortality. Each year, more than two million Americans acquire infections that are resistant to antibiotics and of those, 23,000 will die of those infections. Asymptomatic carriers are at a higher risk of an MDRO infection and become reservoirs for transmission to other patients in health care systems if not accurately identified early. Since there are many types of antibiotic resistant organisms, and the way they cause disease is dictated by their genetics, knowing the exact genetic profile of these organisms is a key step to preventing their ability to infect.
