“…The microencapsulated lemon grass essential oil concentration of 120 µL mL -1 was defined as ideal for use in studies evaluating the addition essential oil to feeds. This concentration is above the in vitro MIC and MBC found, since organic components may affect the activity of the essential oils (PESAVENTO et al, 2015). According to the analysis of the antiseptic activity of the microencapsulated lemon grass essential oil depending on the contact time, the S. aureus bacterium requires a shorter contact time (15 minutes) for bactericidal effect, followed by E. coli (30 minutes) and S. enterica (60 minutes).…”

“…The organic matter in the feed can also affect the MIC and MBC results. Different groups of organic matter, feed components, and chemical characteristics of the oils (PESAVENTO et al, 2015), such as pH and hydrophobicity (NEGI et al, 2012), can hinder the dissolution the essential oils in the feed and affect their action. The CFU (log x+1) of the bacteria evaluated in the feed with oil was counted and compared to the control bacterial growth without oil in the first and seventh day of feed storage.…”

SUMMARY The antibacterial effect of microencapsulated lemon grass (Cymbopogon citratus) essential oil on strains of Escherichia coli (ATCC8739), Staphylococcus aureus (ATCC 6538) and Salmonella enterica subsp. enterica (ATCC 6017), and the stability of this oil in feeds for broiler chickens were evaluated. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined by the macrodilution method, using the microencapsulated lemon grass essential oil at concentrations of 160 μL mL−1, 80 μL mL−1, 40 μL mL−1, 20 μL mL−1, and 10 μL mL−1. The oil concentration of 80 μL mL−1 presented the best results against the three bacteria evaluated. Samples of 200 g of feed mixed with 120 μL g−1 of the microencapsulated lemon grass essential oil was stored to evaluate the oil stability. Feed without microencapsulated lemon grass essential oil was prepared as control. The oil remained active for seven days, with significant reduction of S. aureus (3.08 CFU), E. coli (3.01 CFU), and S. enterica (3.10 CFU). The microencapsulated lemon grass essential oil at concentration of 80 μL mL−1 had antibacterial effect against the E. coli, S. enterica and S. aureus, and maintained stability of the feed for seven days, even with presence of organic matter, which is source of nutrients for pathogens.

“…Diferentes grupos de matéria orgânica e componentes das matrizes alimentares como proteínas, gordura e carboidratos poderão interferir com a atividade do óleo essencial em teste (Pesavento et al 2015). O pH e polaridade são importantes fatores que influenciam na eficácia antimicrobiana.…”

905RESUMO.-Objetivou-se determinar atividade antisséptica do óleo essencial de Lippia origanoides na presença de leite bovino. A composição química do óleo essencial de alecrim pimenta foi determinada por cromatografia gasosa acoplada à espectrometria de massas (CG-EM), sendo detectados 53 compostos, dos quais 16 foram identificados (>0,1% área total). O carvacrol (32,7%), p-cimeno (23%), timilmetil éter, cariofileno (7,98%) e o γ-terpineno (5,40%) foram os componentes mais abundantes. A concentração inibitória mínima para Staphylococcus aureus ATCC 25923 e E. coli ATCC 8739 foi de 60µL/mL, enquanto para Salmonella Choleraesuis ATCC 35640 foi de 90µL/mL. A concentração bactericida mínima foi de 120µL/mL para as três bacté-rias. Avaliou-se a atividade antisséptica do óleo essencial na concentração de 120µL/mL na presença de leite bovino sobre as mesmas cepas bacterianas. O óleo em estudo apresentou efeito inibitório do crescimento das cepas em diferentes tempos de ação (p<0,05). S. aureus apresentou maiores índices de inibição após 5 min de contato e Escherichia coli e Salmonella Choleraesuis após 15 min. O óleo essencial de alecrim-pimenta revelou ser um potencial antimicrobiano natural, mesmo na presença de matéria orgâ-nica constituída de uma matriz nutricional complexa que é o leite bovino. This study aimed to determine the antiseptic activity of the essential oil of Lippia origanoides in the presence of bovine milk. The essential oil chemical composition was determined by gas chromatography-mass spectrometry (CG EM) 53 compounds were detected, of which 16 were identified (>0.1% total area). The carvacrol (32.7%), p-cymene (23%), thymil methyl ether (10.03%), caryophyllene (7.98 %) and γ-terpinene (5.40%) were the most abundant components. The minimum inhibitory concentration for Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 8739 was 60uL/mL, as for this Salmonella Choleraesuis ATCC 35640 was 90uL/mL. The minimum bactericidal concentration was 120μL/ mL for all three bacteria. We evaluated the antiseptic activity of the essential oil in the concentration of 120μL/mL in the presence of bovine milk for the same bacterial strains. The oil under study It showed an inhibitory effect of growth of the strains in different action times (p <0.05). S. aureus showed higher inhibition rates after 5 min of contact and E. coli and Salmonella Choleraesuis after 15 min. The essential oil Lippia origanoides proved to be a natural antimicrobial potential even in the presence of organic matter consists of a complex nutritional matrix is bovine milk.

Essential oils and their components as an alternative in the control of mosquito vectors of diseaseMore than half of the human population is exposed to mosquito-borne infections. Climate change and the emergence of strains resistant to traditionally used insecticides have motivated the search of new agents for mosquito population control. Essential oils have been effective repellents and larvicidal agents. The aim of this work was to review research studies conducted in recent years on the larvicidal activity of essential oils and their components against Aedes, Anopheles and Culex mosquitoes, as well as the latest reports about their possible mechanism of action. Más de la mitad de la población humana está expuesta a contraer infecciones transmitidas por mosquitos. La falta de tratamientos y vacunas eficaces para muchas de estas enfermedades hace que su control dependa principalmente de la utilización de agentes insecticidas (1). Los individuos que habitan en las áreas tropicales están más expuestos a contraer enfermedades transmitidas por vectores y este riesgo ha aumentado en otras zonas debido a la globalización (2).Culex, Aedes y Anopheles son vectores de diversas enfermedades, como la filariasis, el dengue, la malaria, y otras. Culex quinquefasciatus está presente en vastas regiones tropicales del mundo, es la principal plaga doméstica en muchas áreas urbanas y está implicada en la transmisión de muchos agentes patógenos, entre ellos, el causante de la filariasis linfática. Esta enfermedad está ampliamente distribuida en las zonas tropicales, con alrededor de 120 millones de personas infectadas en todo el mundo (3).
