Objective: to evaluate the empirical use of medicinal plants for the treatment of bacterial infections, compared to the theoretical-scientific foundations, according to the literature. Theoretical framework: medicinal plants play a very important role in human history. Through empiricism, many lives were saved and in this process Science evolved, transforming popular knowledge into scientific fact. Resistance of microorganisms, especially bacteria, to conventional drugs is a recurring problem that can be solved with the use of active principles present in vegetables that provide the same environmental pressure as microorganisms and, therefore, may be a viable option. Method: from a qualitative and quantitative approach, using the interview as a data collection method, the research approached respondents in three municipalities, present in three states (RS, SC and PR) that represent the southern region of the country. The method used is known as snowball sampling, or "snowball". The data obtained were compared with the scientific literature, in order to justify or rectify the information provided by the interviewees. Results and conclusion: the research on the use of medicinal plants for the treatment of bacterial infections resulted in a large number of species mentioned by the interviewees. These were grouped and statistically analyzed in order to understand the importance they represent for the population of the studied states. In addition, comparing the data from the interviews with the knowledge already discovered by science, it was found that popular and cultural knowledge has a scientific basis and that technology can be used in this area so that alternative treatments can be obtained in the future for the most diverse symptoms and symptoms. human health problems. The analyzes showed that the most mentioned plants throughout the study were: Boldo (Plectranthus ornatos), Plantain (Plantago major), Malva (Malva sylvestris L.) and Macela (Achyrocline satureoides). Research implications: the structure and composition of the work involve a series of issues related to the population, its values, customs and refer directly to the environmental factors that shape and support human life. The social space, in addition to being respected, must constantly evolve and add technology as a facilitator to the essence of knowledge. The expansion of the open science model is essential for these discussions to be expanded and open space for evolution. Brazil is a large country and this makes the logistics of research that cover the entire territory difficult. Thus, partnerships are needed that involve institutions from different states that can support data collection. Originality/value: this scientific production approached, in an innovative way, relevant facts that can provide a healthy discussion between scientists and the population. The article brings original data, which brings together practical and theoretical research, the universe of popular and scientific knowledge to give evidence to knowledge that is forgotten and goes unnoticed by the academic community. From this debate, there is an attempt to promote more research that adds to this publication and increasingly deepens the scientific facts about the therapeutic potential of bioactives. In addition, ancient knowledge, which has transcended generations and still saves lives, needs to be respected and improved so that scientific institutions return values to citizens, in the form of knowledge, as a way to gratify the role that each person has in managing the environment. Social.

“…Este procedimento tem a finalidade de evitar observações "falso-negativas", expressas pela possível ação somente de inibição microbiana, confundindo com a ação de inativação. Como não são padronizados neutralizadores específicos para extrações vegetais, foram mantidos os indicados no protocolo europeu do teste, que correspondem aos mesmos utilizados com resultados adequados em outros estudos (Mota et al, 2011;Sperotto et al, 2012) com extrações vegetais. Desse modo, pretendeu-se assegurar que o extrato promoveu ação bactericida, e não bacteriostática, sobre os inóculos.…”

A resistência microbiana a compostos químicos convencionais, bem como demanda por tecnologias adequadas ao sistema de produção orgânico/agroecológico motivaram o desenvolvimento desta pesquisa na busca de soluções antibacterianas originadas de extrações vegetais. Os objetivos foram realizar screening fitoquímico e avaliar a atividade dos extratos aquoso (EA) e hidroalcoólico (EH) brutos de Jacaranda micrantha Cham. Com o teste de suspensão quantitativo os extratos das folhas nas proporções 5 g : 100 mL, 10 g : 100 mL e 20 g : 100 mL foram confrontados com as cepas Staphylococcus aureus ATCC 25923 e Salmonella Choleraesuis ATCC 10708, e na de 10 g : 100 mL (100 mg/mL) com isoladas em alimentos de origem animal: S. coagulase positiva (N=20) e S. spp. (N=20). As densidades populacionais de confronto (DP) foram 107, 106 e 105 UFC/mL, nos tempo de contato de oito e 24 horas. Análise fitoquímica qualitativa detectou a presença de compostos fenólicos, taninos condensados e flavonas tanto no EA quanto no EH, e de saponinas apenas no EA. Foi praticamente inexistente a atividade antibacteriana do EA. Já o EH, tomando como referência a proporção 10 : 100, nas 24 h de contato inativou as duas cepas padrões (exceção da Salmonella na maior DP). Frente as isoladas, apresentou melhor atividade sobre S. coagulase positiva reduzindo a DP ou inativando 70% delas na 107, 95% na 106 e 100 % na 105 UFC/mL. As evidências mostram que além das variáveis proporção peso : volume, densidade populacional e tempo de confronto, características intrínsecas dos gêneros e dos indivíduos isolados interferiram na atividade dos extratos. Concluiu-se que o EA pouco apresentou atividade antibacteriana, e que o EH apresentou maior efeito microbiológico frente aos gêneros confrontados.

RESUMO -O fenômeno de resistência apresentada por leveduras aos antimicóticos bem como a necessidade de insumos de higiene para uso em sistemas de criação animal baseados no modelo agroecológico motivaram o desenvolvimento deste trabalho. Os objetivos foram realizar a análise fitoquímica qualitativa e avaliar a ação antimicrobiana/desinfetante do extrato hidroalcoólico bruto [peso:volume de 5g:100 mL (50 mg mL)] das flores de Achyrocline satureioides sobre uma Candida albicans padrão (ATCC 14053) e isoladas de casos de mastite bovina: C. albicans (n = 1) , C. krusei (n = 21) e C. rugosa (n = 9). O teste foi o de suspensão, com as linhagens em três densidades populacionais (DP): 10 5 , 10 4 e 10 3 UFC mL, nos tempos de contato (TC) de 15 e 30 minutos e de 1 até 10 horas. Com resultados da atividade influenciados pelas variáveis DP e TC, todas as leveduras foram inativadas. Como exemplo na mais alta DP: a padrão estava inativada na leitura de 1 h; dos isolados clínicos, o de C. albicans inativado na leitura das 3 h; sete isolados de C. krusei estavam inativados aos 30 min e os outros 14 na leitura de 1 h; sete isolados de C. rugosa estavam inativados na leitura das 4 h, os outros até às 10 h. Os fitoquímicos identificados foram compostos fenólicos, taninos, taninos condensados e flavonóides. As evidências observadas sugerem o potencial do extrato para uso sobre as fontes de infecção em procedimentos de desinfecção ou de antissepsia, ou em formulações que lhe sirvam de veículo.Palavras-Chave: extrato vegetal; Achyrocline satureioides; Candida spp.; produto natural.ABSTRACT -This work was prompted by the phenomenon of yeasts' resistance to antifungals, and the need for sanitation products for use in livestock farming in the agroecological model. The objectives were to undertake a qualitative phytochemical analysis of, and assess the antimicrobial/disinfectant action of, the crude hydroalcoholic extract [weight:volume of 5g:100 mL (50 mg mL)] of flowers of Achyrocline satureioides on standard Candida albicans (ATCC 14053) and isolates of cases of bovine mastitis: C. albicans (n = 1) , C. krusei (n = 21) and C. rugosa (n = 9). The test was that of suspension, the lineages in three population densities (PD): 10 5 , 10 4 and 10 3 CFU mL, at contact times (CT) of 15 and 30 minutes and from 1 up to 10 hours. Activity results were influenced by the PD and CT variables, with all yeasts inactivated. For example, at the highest PD: the standard strain was inactivated in the reading at 1 hr; of the clinical isolates, C. albicans was inactivated in the reading at 3 hrs; seven isolates of C. krusei at 30 minutes and the other 14 at 1 hr; seven isolates of C. rugosa were inactivated in the reading at 4 hrs, with the others inactivated at 10 hrs. Phytochemicals identified were phenolic compounds, tannins, condensed tannins and flavonoids. The evidence observed suggests the extract's potential for use on sources of infection in disinfection/antisepsis procedures, or in formulations which serve as a vehicle.
