This research is important because it allows for the determination of resistance rates to
antibiotics that may not be frequently tested by the clinical microbiology laboratory at
University of Pittsburgh Medical Center (UPMC)-Presbyterian. It also will provide antibiotic
minimum inhibitory concentrations (MICs) for these pathogens which may help in identifying
the best empiric antibiotic option for gram-negative blood stream infections based on known
pharmacodynamic parameters.

Bacterial cultures will be ordered in the normal clinical course of the management of
patients in the liver transplant ICU by the medical team. These cultures are then processed
by the clinical Microbiology laboratory in the normal manner. If these cultures grow a
Gram-negative bacteria, they are eligible for this study. Typically the clinical Microbiology
laboratory saves these bacteria for a period of time after the final microbiology report. At
this time, unless asked otherwise, the bacteria will be placed in biohazardous waste
containers for proper disposal. If these cultures have grown a Gram-negative bacteria, they
are eligible for this study, and will not be disposed of but will be given to the
investigators without identifiers for this study. The antibiotic susceptibility of these
organisms will be tested by the investigators in a separate research laboratory. Mechanisms
of antibiotic resistance may also be assessed.
