Modified Hodge’s test for phenotypic carabpenemase detection. T, test organism; P, positive control (K. pneumoniae); N, negative control (E. coli).
Double disc potentiation method for the phenotypic detection of MBL producing bacteria. Positive results are shown by enlarged zone of inhibtion. MEM, meropenem disc; ETA, ertapenem disc; EDTA, ethylene-diamine tetra acetic acid.
PCR product of blaNDM-1gene on 1.5% agarose gel. N, negative control; P, positive control; T1-T5, test sample; L, DNA ladder.
Agar well diffusion assay for the determination of antibacterial activity of manuka honey. White arrows indicate the zone of inhibition (mm) produced by undiluted manuka honey against NDM-1 producing bacteria.
