摘要
P. syringae 细菌是与农业最相关的病原体之一，因为它感染了大量的农业物种。在这一点上，生物膜的形成决定了其毒性和适应性。在农业领域，氧化锌纳米粒子被认为具有作为纳米肥料和抗菌化合物的潜在用途。从这个意义上说，这项工作旨在研究氧化锌纳米棒（ZnONRs）对植物病原体 P. syringae 的生物膜和浮游状态的影响。与文献不同的是，我们的研究结果表明，测试的病原菌对尺寸极小的异形棒状氧化锌具有很强的抵抗力，因为它们在成熟的生物膜中暴露于高达 500 µg/mL 的高浓度纳米颗粒时没有显示出抑制作用。
Effect of Zinc Oxide Nanorods on biofilms of different pathovars of Pseudomonas syringae
The P. syringae bacteria is one of the most relevant pathogens for agriculture due to the large number of agricultural species it infects. At this point, the formation of biofilms contributes to determining its virulence and fitness. In agriculture, the ZnO nanoparticles are recognized for their potential use as nanofertilizers and antimicrobial compounds. In this sense, this work aimed to study the effect of ZnO nanorods (ZnONRs) on biofilms and in the planktonic state of different pathovars of the plant pathogen P. syringae. In contrast with the literature, our results showed that the tested pathovars are highly resistant to shaped-rod ZnO with tiny sizes because they showed no inhibitory effect in mature biofilms exposed to high concentrations of up to 500 µg/mL of nanoparticles.
