INVESTIGAÇÃO DA AÇÃO ANTIMICROBIANA DO LÁTEX DE MANGABEIRA EM DUAS CEPAS DE BACTÉRIAS CAUSADORAS DE PNEUMONIA
Objective: To evaluate the antimicrobial action of latex of Hancornia speciosa in two strains of bacteria causing Pneumonia. Method: The latex was collected and divided into two samples, a sample diluted in 5 mL of distilled water and dissolved in pure latex. The latex was then submitted to the Minimum Inhibitory Concentration (MIC) test, evaluating the lowest concentration capable of inhibiting the growth of strains of Staphylococcus aureus and Escherichia coli. Results: The Minimum Inhibitory Concentration test showed that the diluted latex had no antimicrobial effect in the Staphylococcus aureus strain and showed total inhibition of Escherichia coli growth. In the latex, in its pure form, showed growth in the first three dilutions tested and total inhibition in the others, behaving equally for both Staphylococcus aureus and Escherichia coli. Conclusion: Latex has antimicrobial action and low toxicity.
