Resumo: The study of medicinal plants enables the discovery of new bioactive compounds. The emergence of microorganisms resistant to antibiotics reinforces this research. Among the microorganisms resistant Mycobacterium tuberculosis shows continuous change by changing their susceptibility profile, resulting in treatment failure. The search for antimicrobial properties of plant extracts and their constituents have been encouraged and intensified. Thus, among many plant species to be investigated, we highlight the juazeiro. Belonging to the family Rhamnaceae, which presents in its composition a wide variety of bioactive secondary metabolites, especially terpenoids, alkaloids of great medical interest. Its main feature is that this tree resists drought very well in the northeastern and became so useful to men, providing shade and fruit, and animals that eat their leaves mucilage. The aim of this study was to evaluate the antimicrobial activity in vitro of extracts juazeiro front of microorganisms, including yeasts, Gram-positive bacteria, Gram-negative bacterium Mycobacterium bovis using the technique of agar diffusion. All extracts showed antimicrobial activity. Among the microorganisms evaluated only Bacillus subtilis, Staphylococcus aureus and Candida albicans were sensitive. None of the evaluated extracts had antimycobacterial activity against Mycobacterium bovis

O aparecimento de microrganismos resistentes aos antibióticos reforça essa pesquisa. Dentre os microrganismos resistentes o Mycobacterium tuberculosis apresenta mutação contínua mudando seu perfil de sensibilidade, acarretando insucesso no tratamento. A busca de propriedades antimicrobianas de extratos de plantas e seus constituintes têm sido incentivada e intensificada. Sendo assim, entre inúmeras espécies vegetais a serem investigadas, destaca-se a Zizyphus joazeiro Mart., pertencente à família Rhamnaceae, que apresenta em sua composição química uma grande diversidade de metabólitos secundários bioativos, destacando-se triterpenóides e alcalóides de grande interesse medicinal. Sua característica principal é que esta árvore resiste muito bem às secas do sertão nordestino, tornando-se dessa forma muito útil tanto para os homens, fornecendo sombra e frutos, como para animais que comem suas folhas mucilaginosas. O objetivo do trabalho, foi avaliar a atividade antimicrobiana, in vitro de extratos de folhas, frutos e casca do caule de Zizyphus joazeiro Mart. contra leveduras e bactérias Gram positivas, Gram negativas e M. bovis. utilizando a técnica de difusão em agar.Todos os extratos brutos apresentaram atividade antimicrobiana. Dos microrganismos utilizados somente Bacillus subtilis, Staphylococcus aureus e Candida albicans mostraram-se sensíveis. Nenhum dos extratos testados apresentou atividade contra Mycobacterium bovisapplication/pdfporUniversidade Federal de AlfenasPrograma de Pós-Graduação em Ciências FarmacêuticasUNIFAL-MGBrasilFaculdade de Ciências Farmacêuticasinfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by/4.0/ZizyphusExtratos VegetaisProdutos de ação antimicrobianaCIENCIAS BIOLOGICAS::MICROBIOLOGIAAvaliação da atividade antimicrobiana de extrato do fruto, folha e casca de caule do Zizyphus joazeiro Martinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/publishedVersion-6425845155986244297600600-3854583469976220812reponame:Repositório Institucional da Universidade Federal de Alfenas - RiUnifalinstname:Universidade Federal de Alfenas (UNIFAL)instacron:UNIFALMelo, Maria Do Socorro FernandesLICENSElicense.txtlicense.txttext/plain;
