摘要

背景与目的:今天,由于耐药性的蔓延和传染病的流行,药用植物的使用增加了。因此,本研究考察了橡树叶和菊苣水醇提取物对福氏志贺氏菌的抑菌作用。方法:采用浸渍法提取水醇提取物,经旋转蒸发器浓缩后立即干燥。其次,采用圆盘扩散法和微肉汤稀释法考察不同稀释度提取物对福氏志贺氏菌的抑菌效果,并与环丙沙星、甲氧苄啶-磺胺甲恶唑两种抗生素进行比较。结果:结果表明,随着浸提液浓度的增加,其对福氏志贺氏菌的抑菌效果也相应增强,MIC和MBC稀释微肉汤法浸提液的抑菌效果分别为3.9和7.8 mg/ml。以紫锥菊提取物为例,除提取物的主要原料(250 mg/ml)外,所有稀释度的细菌都能生长,提取物对福氏志贺氏菌没有抑菌作用。结论:根据本研究结果,橡树叶提取物对福氏志贺氏菌具有良好的抑制作用,与环丙沙星抗生素比较,抑菌效果相近,与甲氧苄啶磺胺甲恶唑比较,抑菌效果更明显。

Antimicrobial Effect of Hydroalcoholic Extracts of Oak Jaft (Quercus Persica) and Echium Amoenum on Shigella Flexneri
Background and Objectives: Today, because of the spread of drug resistance and the prevalence of infectious diseases, the use of medicinal plants has increased. So, in this study, the antibacterial effect of hydroalcoholic extract of Oak jaft and Echium amoenum was investigated on Shigella flexneri. Methods: In this study, hydroalcoholic extracts were extracted by maceration method and concentrated by rotary evaporator then dried immediately. Next, the antimicrobial effect of different dilutions of extracts on Shigella flexneri was investigated by disk diffusion and micro broth dilution methods and compared with two antibiotics, ciprofloxacin and trimethoprim-sulfamethoxazole. Results: The results showed that in proportion to the increase in the concentration of oak jaft extract, its antibacterial effect on Shigella flexneri also increased and 3.9 and 7.8 mg/ml of the extract were obtained by MIC and MBC dilution micro broth method, respectively. In the case of Echium amoenum extract, bacteria were grown at all dilutions (except the main stock of the extract (250 mg/ml)) and the extract had no antimicrobial effect on Shigella flexneri. Conclusion: According to the results of this study, oak jaft extract had a good inhibitory effect on Shigella flexneri and in comparison, with ciprofloxacin antibiotic, a similar inhibitory effect was observed and in comparison, with trimethoprim sulfamethoxazole, more inhibitory effect was observed.
