Veterinary Dermatology, Volume 31, Issue 3, Page 187-e39, June 2020., 2020 Background Bacterial densities likely fluctuate during infection and may exceed the bacterial density used in susceptibility testing. As such, investigation of bacterial killing by antibiotics over a range of varying bacterial densities may provide important differences between compounds and could impact drug selection for therapy.

Biochemical effect of Pr3+ On E. coli(Pr3+对大肠杆菌的生物化学效应)
Zhejiang Daxue xuebao. Lixue ban, 2010 用微量热法研究Pr3+离子对大肠杆菌的生物化学效应.从生成的热谱图分析可以看出,低剂量的稀土离子Pr3+的存在可以缩短细菌的停滞期,增加生长速率常数和最大放热功率,刺激大肠杆菌的生长.相反,较高剂量的Pr3+延长了细菌的停滞期,减小了生长速率常数和最大放热功率,抑制了大肠杆菌的生长.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The past few decades have witnessed multiple outbreaks of pandemics. Hygiene in public facilities is one of the key factors in maintaining public health security. Escalator belts, as frequently touched by passengers, become a potential medium for spreading pathogens.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

四川大学学报. 自然科学版, 2004 对四川卧龙中国保护大熊猫研究中心1只放归亚成体大熊猫和3只圈养亚成体大熊猫肠道正常菌群的种类、数量和分布情况进行了比较研究,结果鉴定出17种细菌,发现放归大熊猫和圈养大熊猫肠道优势菌群均为肠杆菌、肠球菌和乳杆菌.与圈养大熊猫相比,大熊猫放归野外后,肠道菌群中的肠球菌增多,肠杆菌和乳杆菌的数量有所下降,芽孢杆菌和酵母菌的检出率增大.
