WATERTOWN, Mass., Oct. 26, 2016 (GLOBE NEWSWIRE) -- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH) today announced eight data presentations at IDWeek 2016, taking place October 26-30 in New Orleans, LA.  Presentations will include information about the company's phase 3 antibiotic candidate, eravacycline, with data demonstrating consistent and potent in vitro activity against drug-resistant bacteria, including carbapenem-resistant Enterobacteriaceae (CRE), Acinetobacter baumannii, vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA), isolated from recent patients.  Additionally, national prevalence data focused on infections caused by resistant strains of Enterobacteriaceae and Acinetobacter baumannii will be presented suggesting that rates of these types of infections may be higher than previously reported estimates.
