ABSTRACT

Introduction: the emergence of bacterial strains resistant to antibiotics has stimulated the development of new lines of research based on the antibacterial properties of plants used in folk medicine. Veterinary medicine has been taking for itself the benefits of traditional medicine in an attempt to replace the use of antibiotics in the treatment and prevention of mastitis.
Objective: this study is aimed to evaluate the antibacterial activity of hydroalcoholic extracts Syzygium cumini (L.) Skeels, compared to bacteria related to bovine mastitis.
Methods: the extracts were obtained from fresh leaves with ethanol at 92.8° and leaves with ethanol at 70°. The antimicrobial activity of plants was evaluated using the microdilution technique.
Results: the hydroalcoholic extracts fresh plant showed better activity compared with the hydroalcoholic extracts dry leaf, with minimal inhibitory concentration values ranging from 1.5 to 50 % compared to the different microorganisms; highlighting Streptococcus as more effective against all study, with minimal inhibitory concentration equal to 3.1, 1.5, and 1.9 % for Streptococcus uberis, Streptococcus agalacteae, and Streptococcus dysgalacteae, respectively.
Conclusions: these results suggest that the use of leaves of this plant species may constitute a viable alternative for the prevention and treatment of bovine mastitis.
