Technical Information - Multi-Site Gram-Negative Bacilli Surveillance Initiative (MuGSI)
The Multi-Site Gram-Negative Bacilli Surveillance Initiative or MuGSI is a part of the CDC’s Emerging Infections Program (EIP) Healthcare-Associated Infections Community Interface (HAIC) activity. Through MuGSI, CDC is conducting active population- and laboratory-based surveillance in a defined surveillance catchment for six carbapenem-resistant organisms which include Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, Klebsiella pneumoniae, Klebsiella oxytoca, and Acinetobacter baumannii.
- To evaluate the population-based incidence of carbapenem-nonsusceptibility among five common strains of Enterobacteriaceae and Acinetobacter baumannii, and describe how the incidence changes over time
- To better characterize carbapenem-nonsusceptible strains in sites submitting data in order to inform prevention efforts
- To describe known resistance mechanisms among a subset of carbapenem-nonsusceptible Enterobacteriaceae
- Surveillance Population
Surveillance for these MuGSI organisms is conducted in eight EIP site. The table below illustrates the population under surveillance for each EIP site as of January 2015.
(5 county Denver area)
(8 County Atlanta area)
(3 county Baltimore area and Baltimore City)
(2 metro Twin Cities counties)
(1 county Albuquerque metro area)
(1 county Rochester metro area)
(3 county Portland area)
(8 county Nashville metro area)
