The impact of iron metabolism system on a common mechanism of antimicrobial lethality [PDF]
, 2016 传统研究认为不同种类的抗生素有其各自不同的杀菌途径，然而近年人们发现了一条抗生素杀菌的共用通路，那就是当细菌细胞受到抗生素致死性刺激时，呼吸链将代谢异常产生大量活性氧簇（ROS），而铁离子对ROS介导的杀菌至关重要。本研究参阅近年来国内外研究结果，通过基因突变、铁离子竞争物等实验方法着重研究了细菌铁代谢系统与抗生素共有杀菌途径之间的关系，重点讨论抗生素刺激下铁离子的调控及其与抗生素介导ROS形成的相互作用关系。对于细菌耐药机制的研究与寻找新型药物作用靶点、开发新药有重要意义。 本研究对铁储存蛋白相关基因（

Veterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Establishment and application of a HTS assay for inhibitors of Vibrio vulnificus DXS and DXR [PDF]
, 2016 弧菌病是水产动物最主要的细菌病之一，其爆发性强，死亡率高，每年给我国水产养殖业造成重大经济损失。目前细菌性病害的防治主要依靠抗生素及化学药物。然而，抗生素的大量盲目地使用，导致了耐药性菌株不断出现，使病害更加难以控制，因此需要不断地寻找新的、安全的抗菌药物。 类异戊二烯是弧菌合成细胞壁结构单元肽聚糖的骨架分子，也是参与能量代谢等多种生物过程的十分重要的生理活性物质。生物体内的类异戊二烯类化合物主要有两种生物合成途径：甲羟戊酸（MVA）途径和2-甲基-D-赤藓糖醇-4-磷酸（MEP）途径 ...

Zhongguo shiyan zhenduanxue, 2011 目的探讨呼吸道分离的金黄色葡萄球菌耐药情况、耐药的菌株是否有遗传稳定性,及对其他种类的抗生素有无交叉耐药。方法把试验菌株与标准菌株在不同含药平皿中接种传代,观察MIC值的变化,再测定遗传稳定性及有无交叉耐药。结果试验菌株与标准菌株多次传代后,耐药突变菌株获得的耐药性是稳定的。未对其他种抗生素发生交叉耐药。结论合理选用抗生素,监测细菌耐药性、掌握耐药机制等综合措施的实施,才能减缓细菌耐药性的增长。

To prepare antimicrobial bamboo fabric by oxidization method and the research of related properties [PDF]
, 2016 根据相关文献和世界卫生组织报告，目前在世界范围内仍然有多于8.8亿的人口不能获得安全、卫生的饮用水源，这一情况主要集中在不发达地区。到目前为止，世界上每年仍有大约220万人死于饮用不卫生水导致的痢疾等其他疾病，这其中大部分是儿童。造成这一问题的主要原因是缺乏安全可靠、廉价的水处理技术。 大量文献表明，磺胺嘧啶银对皮肤烧伤、溃疡等伤口处易感染细菌具有较好的杀灭效果，可对伤口化脓及感染情况进行有效控制。但是磺胺嘧啶银及其他低浓度银盐对体液或者水不具有耐受性，极容易流失，使得其使用范围受到一定的限制。研究发现，
