Resumo: Syzygium aromaticum L. and Ocimum gratissimum L. essential oils were tested for their effectiveness in reduction the counts of inoculated Staphylococcus aureus and Escherichia coli in sheepmeat. The inhibitory effect was analysed by disk diffusion and broth macrodilution method with four strains and seven concentrations. Disinfectant activity of the oils was assessed using the suspension test with two strains and two concentrations. The inhibition was observed at concentrations 400, 200 and 100 μL/mL. Syzygium aromaticum L. oil was better than Ocimum gratissimum L. against bacteria isolated from sheep carcasses. The minimum bactericidal concentration of the essential oils aginst inocula ranged from 50 to 200 μL/mL. The suspension test showed that after 5 minutes of contact, Syzygium aromaticum L. disinfectant at 400 μL/mL deactivated the inoculants completely. The results demonstrated that essential oils exerted a significant bactericidal and bacteriostatic action against pathogens.

Foram utilizadas quatro cepas e sete concentrações dos óleos nas técnicas de disco-difusão e macrodiluição em caldo empregadas na análise do efeito inibitório. No teste de suspensão, trabalhou-se com duas cepas e duas concentrações na determinação da atividade desinfetante. A inibição foi observada nas concentrações de 400, 200 e 100 μL/mL. O óleo de Syzygium aromaticum L. foi melhor em relação ao alfavacão para inativar as bactérias isoladas das carcaças de ovinos. A concentração bactericida mínima dos óleos contra os inóculos variou de 50 a 200 μL/mL. O teste de suspensão mostrou que após 5 minutos de contato com o desinfetante de cravo na concentração de 400 μL/mL os inóculos foram completamente inativados. Os resultados mostraram significativa atividade bactericida e bacteriostática dos óleos essenciais frente aos patógenos.Universidade Federal de Minas Gerais2019-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/1595110.35699/2447-6218.2019.15951Agrarian Sciences Journal; Vol. 11 (2019); 1-12Caderno de Ciências Agrárias; v. 11 (2019); 1-122447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGenghttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/15951/13051https://periodicos.ufmg.br/index.php/ccaufmg/article/view/15951/13081Copyright (c) 2019 Caderno de Ciências Agráriasinfo:eu-repo/semantics/openAccessOliveira, Larissa de Sales, Sabrina de Souza2020-10-05T16:32:11Zoai:periodicos.ufmg.br:article/15951Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2020-10-05T16:32:11Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false
