| antibiotic resistance | The ability of a bacterium tosynthesise a protein that neutralises an antibiotic. (09 Oct 1997) |
| antibiotic resistance gene | Genes in a microorganism which confer resistance to antibiotics, for example by coding for enzymes which destroy it, by coding for surface proteins which prevent it from entering the microorganism, or by being a mutant form of the antibiotic's target so that it can ignore it.
