【 摘 要 】

The aim of this study was to evaluate the sensitivity of the S.aureus to the extract of Mimosa tenuiflora (Wild) Poir. (jurema-preta). Twenty five strains of S. aureus were isolated from milk samples with description of clinical and subclinical mastitis and submitted to antimicrobial activity test of the M. tenuiflora extract. The sensitivity in vitro tests were carried out using the agar difusion method (well diffusion method). After that, 50μL of the extract were inoculated in the following dilutions: 1:1; 1:2; 1:4; 1:8; 1:16; 1:32; 1:64; 1:128; 1:256; 1:512. The plates were incubated at 37 ºC during 24 and 48 h. The tests were made in triplicate. Halos of inhibition were observed between 6 and 25 mm of diameter. The percentage of sensitivity of the tested samples was distributed in: 1:1 to 1:32 (100%), 1:64 (92%); 1: 128 (72%); 1:256 (28%); 1:512 (0%). The study of M. tenuiflora on the tested S. aureus samples it demonstrated that the plant has antimicrobial action.
