The test could also be used to quickly identify carbapenem-resistant
isolates from fecal specimens screened
for multidrug-resistant bacteria (Figure 2). This capability
would be valuable in preventing outbreaks. To determine
positive and negative predictive values of the test, additional
evaluations will be required with strains isolated
from clinical samples screened on different types of selective
media. The use of the Carba NP test may also support
novel antimicrobial drug development by facilitating
patient enrollment in pivotal clinical trials. Its use as a
home-made test may contribute to the global surveillance
network
