Performance of Quantification of Modified Hodge Test: An Evaluation with Klebsiella pneumoniae Carbapenemase-Producing Enterobacteriaceae Isolates

Figure 1

Quantification of Modified Hodge Test (MHT). The enhanced growth ratio of ETP and MEM subtracts were obtained from the measure (mm) of the enhanced growth of E. coli ATCC 25922 for both the isolate and the KPC-producing positive control (K. pneumoniae ATCC BAA 1705) and a ratio was calculated. In this example, B is the positive control and the enhanced growth measured for ETP was 10 mm. The enhanced growth measured for isolates A and C was 5 and 2 mm, respectively, resulting in ETP enhanced ratios of 0.5 and 0.2, respectively.
