Fitoterápico e sua ação antibacteriana: uma alternativa para o tratamento de diarreia neonatal bovina

Abstract

The high incidence of neonatal diarrhea and the lack of diagnosis hinder the effective treatment of this disease, thus increasing the microorganisms that show resistance to the molecules used in the clinical routine of the properties. Phytotherapy has been shown to be an effective and sustainable alternative to the use of chemical molecules in different areas of human and animal medicine. The use of leaf and fruit preparations to fight diseases not only addresses the issues of sustainability and organic production, but also the demand for new molecules to fight microorganisms resistant to the drugs available on the market. Therefore, the objective of the present study was to evaluate the in vitro effects of two extracts obtained from the peel of the fruit of Plant A against strains of Escherichia coli and Salmonella sp. isolated in the laboratory from the feces of calves affected by neonatal diarrhea. Hydroalcoholic extracts 70% and aqueous 1% extracted from the fruit peel were used. The minimum bactericidal concentration (CBM) of the extracts was determined by checking the growth or not of microorganisms. Both extracts proved to be efficient against the strains of Salmonella sp., both did not show efficiency against the different strains of E. coli in any of the tested concentrations. Thus, the initial study demonstrates the antimicrobial potential of the extracts and may in the future be an alternative to the chemical molecules used in the clinical routine.
