The MultiRapid ATB NP test. Column D shows the solution with imipenem–relebactam (IPR, 12/4 mg/L);. Reference strain Escherichia coli ATCC 25922 was inoculated in wells A1–F1; Positive control resistant to all the antibiotics was inoculated in wells A2–F2; First tested strain (resistant to CZA, MEV, and IPR) was inoculated in wells A3–F3; Second tested strain (resistant to CZA and FDC) was inoculated in wells A4–F4; and NaCl 0.85% was inoculated in wells A5–F5. Bacterial growth is shown by a colour change of the medium from red to yellow.
