Considering Gram-negative selective
media, regardless of carbapenemase
production, the Carba NP test was
interpretable for only 63 % and 71 % of the
strains recovered from Drigalski agar and
MacConkey agar, respectively (Table 1).
In addition, when the Carba NP test was
interpretable, OXA-48, KPC, VIM and
IMP producers were all detected, whereas
only 50 % of NDM producers were
detected
