MedlinePlus related topics: Pneumonia

Group/Cohort Intervention/treatment
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).

Primary Outcome Measures :
  1. 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 :
  1. 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 ]
