Detection and Analysis of Antibiotic Resistance Genes in a Wastewater Treatment Process [PDF]

open access: yes, 2015
目前,随着在越来越多的污水样品和处理后的生物残渣中检测到耐药菌和抗性基因,人们已逐渐认识到污水处理厂是这二者的一个主要容留场所。环境中的这些抗性基因可以作为感染源水平转移到人类机体微生物中,也因此导致了抗生素耐药性的扩大化。由于胞外基因分子可以在水环境中保持相当长时间的生物活性,而目前关于污水中胞外基因的报道甚少,本文将着重调查典型的污水处理工艺——膜生物反应器中的胞外基因,并在此基础上进一步考察膜生物反应器出水中的胞外抗性基因(尤其是磺胺甲恶唑抗性基因)可能对细菌产生的抗性基因转化。 首先 ...

Use of saline‐soaked bacterial culture swabs increases bacterial recovery in dogs with superficial bacterial folliculitis

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 621-629, October 2025.
Background – Canine superficial bacterial folliculitis (SBF) is a common recurrent condition with a growing requirement for culture and susceptibility as a consequence of increased antimicrobial resistance and antimicrobial stewardship. Different opinions persist about the ideal technique for culture sample acquisition, which varies with lesion ...

热化疗逆转人肝癌细胞系HepG2/ADM多药耐药性的实验研究

open access: yesZhongguo shiyan zhenduanxue, 2007
目的研究热化疗对多药耐药人肝癌细胞系HepG2/ADM耐药性的影响并探讨相关的机制。方法通过MTT法测定热化疗对多药耐药人肝癌细胞系HepG2/ADM耐药性影响;利用流式细胞仪检测细胞内ADM浓度变化。结果热化疗使多药耐药人肝癌细胞系HepG2/ADM耐药性降低;细胞内阿霉素浓度提高。结论热化疗具有逆转多药耐药人肝癌细胞系HepG2/ADM耐药性的作用,可能与细胞内阿霉素浓度提高有关。

貂源肺炎克雷伯菌分离鉴定与耐药性检测

open access: yes野生动物学报, 2021
为鉴定引起水貂(Neovison vison)出血性肺炎的病原菌,并分析其耐药性,采集患出血性肺炎貂的肺脏、心血、肝脏等病料组织86份,采用细菌分离鉴定和PCR方法对采集的病料组织进行肺炎克雷伯菌(Klebsiella pneumoniae)鉴定,采用人工感染动物性试验、KB药敏纸片法分别检测其致病性、耐药性。结果显示:从采集的86份病料组织样品分离得到42株致病性肺炎克雷伯菌,该致病菌对阿莫西林、氨苄西林、庆大霉素、新霉素、氟苯尼考、强力霉素、磺胺二甲氧嘧啶7种药物耐药性较高,耐药率为595 ...

Nanodrug delivery in reversing multidrug resistance in breast cancer cells [PDF]

open access: yes, 2016
乳腺癌细胞产生多药耐药(Multidrugresistance,MDR)是乳腺癌化疗失败最主要的原因之一,深入研究拮抗或逆转乳腺癌多药耐药有着重要的理论和临床意义。紫杉醇(Paclitaxel,PTX)是目前临床上广泛应用的广谱抗癌药物。临床广泛使用的紫杉醇制剂(商品名“泰素”)毒副反应严重,超敏反应强烈,无明显靶向性,可诱发多药耐药,因此紫杉醇新制剂研究是当前国际国内的热点问题。 本文旨在研制出具有良好临床适应性、可逆转肿瘤多药耐药的紫杉醇纳米制剂,并使其具有磁靶向和光动力治疗的多重功能。首先 ...
