A large Los Angeles teaching hospital has told scores of patients they may have been exposed to a drug-resistant bacterial "superbug" during endoscopy procedures that infected seven patients and contributed to two deaths. More than 170 patients who may have been infected by the carbapenem-resistant Enterobacteriaceae, or CRE, are being offered home testing kits that would be analyzed by the University of California at Los Angeles hospital system, UCLA officials said. The possible exposures occurred at the UCLA Ronald Reagan Medical Center between Oct. 3 and Jan. 28 during procedures in which a specialized endoscope is inserted down the throat to diagnose and treat pancreatic and bile duct diseases.
