It is common practice to define a bacterium with unequal antibiotic susceptibility
phenotypes as a different genotype. Here, we describe the utility of this practice
for Acinetobacter baumannii. We determined antibiotic susceptibility for 19 clinical isolates of A baumannii. Repetitive sequence polymerase chain reaction method was used to determine genotypes.
Although all isolates were of the same genotype, 79% were predicted to be different
based on susceptibility patterns. The antibiotic susceptibility phenotype does not
accurately predict the genotype of A baumannii.
