To determine the prevalence of MRSA isolates with marginal susceptibility to vancomycin or heteroresistance.

Condition Intervention
Methicillin-resistant Staphylococcal Aureus Pneumonia Other: etest susceptability testing

Further study details as provided by University of Kentucky:

Primary Outcome Measures:
  • Determine the prevalence of PAL hetero-VISA within MRSA isolates using vancomycin E-tests and contrast this with E-tests for teicoplanin, linezolid and tigecycline. [ Time Frame: 1 time ]

Secondary Outcome Measures:
  • Determine the sensitivity and specificity of automated susceptibility testing for PAL MRSA for vancomycin and alternative agents teicoplanin, linezolid and tigecycline by comparing automated sensitivity testing to E-test results. [ Time Frame: 1 time ]

Estimated Enrollment: 1250
Study Start Date: September 2008
Study Completion Date: July 2010
Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
PAL samples collected for pneumonia evaluation
Other: etest susceptability testing
E-test methodology is performed on all MRSA samples using standardized inoculum (0.5 McFarland) for Tigecycline, Vancomycin, Teicoplanin, and Linezolid. E test is performed using heavy inoculum for Vancomycin and Teicoplanin (2.0 McFarland).
