Abstract

Escherichia coli is a pathogen associated with infections in piglets in the post-weaning phase, its pathogenicity is related to the animal's susceptibility to bacterial enterotoxins. The objective of the present study was to determine the EOs activity against E. coli strain, in the form planktonic and sessile. Although the Disc-Diffusion tests to determine the Minimum Inhibitory Concentration, do not fully corroborate with the other analyzes of this study, it was noticed bacteria inhibition. The EOs were prepared at 0.4%, 0.8% and 1.0% for tests. The tested EOs were effective against E. coli planktonic cells (p<0.05). As for the sessile cells, the most significant result was inhibition and 100% sessile cells at the concentration of 1.0% of Cymbopogon citratus EO. Although there was resistance in some treatments, the tested EOs demonstrated inhibition capacity, constituting promising alternatives for the control of E. coli, especially of planktonic cells.

精油对猪腹泻病例分离的大肠杆菌浮游细胞和固基细胞的抑菌作用

大肠杆菌是一种与断奶后仔猪感染相关的病原体，其致病性与动物对细菌肠毒素的易感性有关。本研究的目的是确定EOs对浮游和固定式大肠杆菌菌株的活性。虽然碟形扩散试验确定的最低抑菌浓度与本研究的其他分析结果不完全一致，但发现对细菌有抑制作用。分别以0.4%、0.8%和1.0%的浓度制备EOs进行试验。对大肠杆菌浮游细胞有抑制作用(p<0.05)。在柠檬酸Cymbopogon citratus EO浓度为1.0%时，对无柄细胞的抑制效果最显著，无柄细胞达到100%。虽然在某些处理中存在耐药性，但经测试的EOs显示出抑制能力，是控制大肠杆菌，特别是浮游细胞的有希望的替代品。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
