AVALIAÇÃO "IN VITRO" DA ATIVIDADE ANTIMICROBIANA DA BENZIDAMINA.

This paper aims the evaluation of the possible antibacterial an antifungical activity of benzydamine.Minimum inhibitory Concentration and Minimum Bactericide/Fungicide concentration in several microorganism samples were determined. Agar Difusion (tecnic of well)and tube dilution were the techniques used. Evaluation of microorganisms sensibility to benzydamine , was made through the reading of the inhibition halos in the agar difusion and growth inhibition n the tube dilution technique. The results showed that benzydamine has an antimicrobial activity in the yeast samples and in the tested bacteria. The comparison of the two techniques showed that in agar difusion technique the minimum inhibitory concentration value (MIC) was higher than in the tube dilution one. [ABSTRACT FROM AUTHOR]
