Abstract

Introduction: Although many backcountry first aid kits contain antibiotic ointment, the supply can be quickly exhausted if a patient has extensive wounds or if there are multiple patients.

Methods: We assessed the antibacterial properties of bark extract from four North American woody plant species known to native Missourians as medicinal plants (Quercus macrocarpa, Salix humilis, Pinus echinata, and Hamamelis vernalis). We tested their antimicrobial properties, with the disc diffusion technique, against four common pathogenic bacterial species: Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, and Enterobacter aerogenes (now known as Klebsiella aerogenes).

Results: We report evidence of antibacterial activity of bark extract from all four plant species.

Conclusions: Our results confirm that traditional uses of these species may be useful in fighting infection and could be especially useful in a wilderness setting when modern antibiotics are exhausted.

四种北美树种树皮的抗菌活性
简介:尽管许多野外急救包中都有抗生素软膏,但如果病人的伤口面积很大或有多个病人,这些药膏很快就会用完:我们评估了四种北美木本植物树皮萃取物的抗菌特性,这四种植物是密苏里州本地人熟知的药用植物(Quercus macrocarpa、Salix humilis、Pinus echinata 和 Hamamelis vernalis)。我们利用圆盘扩散技术测试了它们对四种常见致病细菌的抗菌特性:结果:结果:我们报告了所有四种植物树皮提取物的抗菌活性证据:我们的研究结果证实,这些植物的传统用途可能有助于抗感染,尤其是在现代抗生素用尽的野外环境中。
