An Ultrasmall Strontium‐Loaded Polydopamine Nanoformulation for Near‐Infrared‐Enhanced Periodontitis Therapy via Photodynamic Gas‐Promoted Antibacterial and Bone Repair

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

抑制多种植物病原菌的几丁质酶产生菌X2-23的鉴定

open access: yes四川大学学报. 自然科学版, 2002
样品经纹枯病菌细胞壁培养基富集后 ,从 16 6株几丁质酶产生菌中分离得到一株高产几丁质酶细菌X2 2 3.X2 2 3对所有指示菌如水稻纹枯病、稻瘟病、水稻恶苗病、小麦赤霉病、油菜菌核病以及水稻白叶枯病等多种病原菌均具强烈的拮抗作用 .当X2 2 3加入上述病原真菌的液体培养基中时 ,由光学显微镜和电子显微镜观察发现病原真菌菌丝发生扭曲、变形、菌丝细胞壁肿胀裂解、细胞质聚集、原生质体外溢或裸露等异常现象 .几丁质酶活性达 2 5 .5U/mL .该细菌经鉴定为圆孢芽孢杆菌 ...

绿海龟细菌性疾病流行病学调查

open access: yes野生动物学报, 2022
中国绿海龟(Chelonia mydas)繁育技术的进步促进了自然保护区内绿海龟种群规模的不断增加,细菌性病原感染成为威胁绿海龟(稚龟)繁育安全的首要问题。为深入了解中国绿海龟(稚龟)细菌性疾病流行情况,在2019—2021年对广东惠东海龟国家级自然保护区内的患病绿海龟(稚龟)进行了病原菌分离鉴定,采用16S rRNA分子鉴定结合细菌生化鉴定技术,共分离鉴定疑似病原株45株,涉及10个菌属,革兰氏染色显示均为革兰氏阴性细菌。弧菌属(Vibrio)细菌19株,占疑似病原菌的42.22%,其中溶藻弧菌(V ...

Chemical Stability of Ceftazidime Compounded in Saline, Glycerin and Dexamethasone‐SP Solutions Stored at −20°C, 4°C and 25°C Over a 60 Day Period

open access: yesVeterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.
ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

麝化脓病细菌性病原诊断鉴定

open access: yes野生动物学报, 2012
目的:寻找麝化脓病细菌性主要病原,为防治麝化脓病以及麝化脓病病原的研究奠定基础。方法:病料组织触片镜检,兰氏染色后镜检,用LB培养基、鲜血培养基对56份病料进行病原菌的分离培养,观察菌落形态,兰氏染色镜检,用微量生化反应管对细菌进行生化试验,对分离得到的菌株用纸片法进行药物敏感性试验。结果:从分离菌的形态、培养特征、生理生化特性等,可以证实分离的3种菌分别为巴斯德菌(Pasteurella spp)或绿脓杆菌(Pseudomonas aeruginosa)或耶尔森菌(Yersinia spp ...

Climate and Land‐Use Changes Predicted to Jointly Drive Soil Fungal Diversity Losses in One‐Third of North American Coniferous Forests

open access: yesGlobal Change Biology, Volume 31, Issue 11, November 2025.
This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...
