Abstract
The present invention provides a method of determining the antibiotic susceptibility of a microorganism comprising the following steps. First, a culture of the microorganism whose susceptibility is to be determined is admixed with an antibiotic to which susceptibility is to be assayed, and a permeabilizing agent for the microorganism present in a non-growth-inhibiting microorganism-permeabilizing effective amount to form an assay culture. Next, the assay culture is incubated under appropriate culture conditions and for a time sufficient to determine the susceptibility of the microorganism to the antibiotic. In another aspect, the present invention provides an improved method for antibiotic susceptibility testing of a microorganism in a culture by admixing the culture with an antibiotic to which susceptibility is to be assayed, and incubating the culture for a time sufficient to determine the susceptibility of the microorganism to the antibiotic, the improvement comprising admixing the culture with a permeabilizing agent for the microorganism present in a non-growth inhibiting microorganism-permeabilizing effective amount.
