Efeitos da própolis sobre as bactérias encontradas em lesões cutâneas crônicas

Abstract

On average 5 million Brazilians live with chronic ulcerative lesions, which has a huge socioeconomic impact, since this condition is the 10th that most removes workers from their occupations. In recent years, there has been a growing interest in folk medicine and the use of natural products such as propolis from Apis mellifera bees. Propolis is widely accepted for its various therapeutic properties, such as antioxidant, antiviral, anti-inflammatory, antifungal and even anticancer. Thus, the present study aimed to describe the behavioral variation of bacteria when subjected to contact with different concentrations of propolis, aiming its use as a therapeutic cover. This is an experimental research of descriptive exploratory nature carried out in a private laboratory, accredited by the DICQ (National Accreditation System) and reference in the performance of laboratory tests in the city of Campos dos Goytacazes-RJ. Two experimental methodologies were developed. In common for both were petri dishes with Mueller Hinton agar medium previously sown with control strains of bacteria Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa and Staphylococcus aureus, which came in contact with three concentrations of propolis (5%, 10%, 25%) arranged in ascending order on the plate and later stored in a greenhouse between 35.5oC and 36.5oC. As a result it was visualized that the action of propolis was effective on S. aureus in both experiments, and on the 5th test day of Experiment A showed positive and differentiated evaluations between the concentrations. In the gram-negative bacteria tested no action was observed at any concentrations. It was concluded that propolis showed antibacterial action at all concentrations tested in gram-positive bacteria in contrast to the observed gram-negative bacteria. However, there is also the need for the presence of nurses as a researcher and active in the development of new health technologies aiming at the economy of the Unified Health System and the treatment of wounds favoring a better quality of life for patients with chronic injuries.
