“…In recent years, research has been conducted on the susceptibility of essential oils and their chemical compounds to different bacteria species isolated from domestic animals, humans, and food [9, 11, 12, 20, 27, 28]. The present study is the first to present results on the susceptibility of 22 E. coli strains from Howler monkeys ( Alouatta spp.)…”

This study evaluated the in vitro antibacterial activity of essential oils from Lippia graveolens (Mexican oregano), Origanum vulgaris (oregano), Thymus vulgaris (thyme), Rosmarinus officinalis (rosemary), Cymbopogon nardus (citronella), Cymbopogon citratus (lemongrass), and Eucalyptus citriodora (eucalyptus) against Escherichia coli (n = 22) strains isolated from Alouatta spp. feces. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined for each isolate using the broth microdilution technique. Essential oils of Mexican oregano (MIC mean = 1818 μg mL−1; MBC mean = 2618 μg mL−1), thyme (MIC mean = 2618 μg mL−1; MBC mean = 2909 μg mL−1), and oregano (MIC mean = 3418 μg mL−1; MBC mean = 4800 μg mL−1) showed the best antibacterial activity, while essential oils of eucalyptus, rosemary, citronella, and lemongrass displayed no antibacterial activity at concentrations greater than or equal to 6400 μg mL−1. Our results confirm the antimicrobial potential of some essential oils, which deserve further research.

“…Oregano, rosemary, eucalyptus, citronella, lemongrass, and thyme essential oils were purchased from Essential 7 (Roswell, New Mexico, USA), and all of them came in sealed amber glass bottles. EOs selection was based on previous studies from our laboratory and other studies [10–12, 19, 24, 25]. …”

“…Oregano EO was the most effective against bacteria tested, with DIZs ranging from 35.29 mm ( S. xylosus ) to 57.90 mm ( E. amnigenus ). Santurio et al [44] reported the antimicrobial activities of EOs of eight spices against E . coli strains isolated from poultry and cattle faeces by determining the MICs using the broth microdilution technique.…”

Infectious diseases caused by pathogens and food poisoning caused by spoilage microorganisms are threatening human health all over the world. The efficacies of some antimicrobial agents, which are currently used to extend shelf-life and increase the safety of food products in food industry and to inhibit disease-causing microorganisms in medicine, have been weakened by microbial resistance. Therefore, new antimicrobial agents that could overcome this resistance need to be discovered. Many spices—such as clove, oregano, thyme, cinnamon, and cumin—possessed significant antibacterial and antifungal activities against food spoilage bacteria like Bacillus subtilis and Pseudomonas fluorescens, pathogens like Staphylococcus aureus and Vibrio parahaemolyticus, harmful fungi like Aspergillus flavus, even antibiotic resistant microorganisms such as methicillin resistant Staphylococcus aureus. Therefore, spices have a great potential to be developed as new and safe antimicrobial agents. This review summarizes scientific studies on the antibacterial and antifungal activities of several spices and their derivatives.

Resumo:Este estudo avaliou a emulsão líquida de óleos essenciais de orégano (Origanum vulgare) e alecrim (Rosmarinus officinalis labiatae) no controle dos sinais clínicos da diarreia neonatal em leitões. Foram monitorados 1.334 leitões lactentes, com peso vivo médio inicial de 1,5kg, quanto aos sinais clínicos de diarreia neonatal. O delineamento experimental foi o inteiramente casualizado e com três tratamentos (T): (T1) controle (solução fisiológica), (T2) mescla dos óleos essenciais e (T3) enrofloxacina. Os animais que receberam o T1 apresentaram sinais clínicos característicos de diarreia diferindo (P<0,01) dos demais tratamentos. O percentual de cura da diarreia dos leitões não diferiu (P>0,01) entre os tratamentos, independente da ordem de partos (OP) das mães. Já leitões com sinais clínicos de diarreia, nascidos de fêmeas com OP inferior a três apresentaram maior percentual de cura (74,6%), se comparados aos leitões diarreicos de fêmeas com OP entre três e cinco (68,2%) e superior a cinco (56,4%). As análises microbiológicas das fezes e histológicas do epitélio ileal não apresentaram diferenças (P>0,01) entre os tratamentos. A emulsão com óleos essenciais de orégano e alecrim (2mL kg -1 ), para leitões entre zero e o oito dias de vida, pode vir a substituir a enrofloxacina no controle dos sinais clínicos das diarreias neonatais. Palavras-Chave: enrofloxacina; Origanum vulgare; Rosmarinus officinalis labiatae. Abstract:This study evaluated the liquid emulsion of oregano and rosemary essential oils in the control of neonatal diarrhea in piglets. We monitored 1334 piglets with average weight of 1.5 kg regarding the clinical signs of neonatal diarrhea. The design was completely randomized with three treatments (T): (T1) control (saline), (T2) essential oils and (T3) enrofloxacin. T1 showed characteristic
