Antibiofilm action of glycolic extract over and absence of toxicity in .

Objectives: This study aimed to evaluate the antibiofilm activity and toxicity of the glycolic extract of "" over multidrug-resistant strains of as alternative therapy to be investigated.

Methods: A bacterial inoculum of each bacterial strain (4a, 5a, 9a, 12a, ATCC 19606) of was prepared and adjusted by the spectrophotometer. The microdilution broth method was performed to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC).
