MeSH definition : A large group of aerobic bacteria which show up as pink (negative) when treated by
the gram-staining method. This is because the cell walls of gram-negative bacteria
are low in peptidoglycan and thus have low affinity for violet stain and high affinity
for the pink dye safranine.;
MeSH synonym : gram negative aerobic bacteria;
MeSH hyponym : achromatium;
Related MeSH term : achromatiaceae; achromobacteriaceae;
