ANTIMICROBIAL EFFECT OF 60% ETHANOLIC EXTRACT OF CAESALPINIA ESPINOSA(TARA) ON ENTEROCOCCUS FAECALIS

Abstract

OBJECTIVE:Enterococcus Faecalis is considered one of the strains more resistant to the solutions group disinfectants commonly manipulated in the treatments of ducts The objective of this research was to establish the production of inhibitory effect of Caesalpinia spinosa (tare) on the Enterococcus Faecalis strain Methods. Was a seeding of the strain ATCC 29212 (Enterococcus Faecalis) plates with Agar brain heart, then it is placed on the surface of 5 mm diameter discs with NaClO to the 5.25% as control and Caesalpinia spinosa (tare) to 60% as a group experimental, for each substance was used 24 samples; then incubated in anaerobic Chamber plates at 37 orC, was subsequently taken measures 24, 48 and 72 hours after the resulting inhibitory halo Results. Data were sorted and processed, indicating the average of the measurement of both the Caesalpinia spinosa inhibitory halo resulting this greater than that formed by sodium hypochlorite, applied a Test of normality for data obtained with both substances, determining that such data had a normal distribution. Then applying Student‘s T (p<0.05), giving as result statistically significant difference between the data obtained for both substances Conclusions. The Caesalpinia spinosa, proved to have antibacterial effect against Enterococcus Faecalis, its measures were varied and mostly higher than sodium hypochlorite.
