![]() Various sources suggest there may be as many as one trillion species – although the vast majority of these have not yet been discovered. They are one of the first life forms to exist on Earth and have been around for approximately three billion years. Public Engagement and Patient Support (PEPS) Committeeīacteria are very small (usually single-cell) organisms.Antibiotic resistance in the environment.Antibiotic resistant bacteria in healthcare.baumannii in intensive-care units were multidrug-resistant. In 2008, based on NHSN data, 13% of E.The percentage of gram-negatives that are resistant to drugs is increasing.CDC’s National Healthcare Safety Network (NHSN) captures information on antibiotic resistance patterns in gram-negative bacteria in healthcare settings.Monitoring gram-negative healthcare-associated infections CDC is working with states to identify isolates with unusual resistance and to determine new mechanisms of resistance among multidrug-resistant gram-negatives, including the recent identification of a new mechanism of resistance in patients returning from Asia.CDC is collaborating with laboratory standards-setting institutions to identify and recommend laboratory tests for the accurate detection of carbapenemase-mediated resistance.Laboratory tests for detecting resistance In addition to these outbreaks, CDC’s reference laboratory has confirmed carbapenemase resistance in bacteria for 32 other U.S.This collaboration led to important improvements in infection control in military medical facilities. ![]()
