Cefotaxime-Resistant Neisseria meningitidis Sequence Type 4821 Causing Fulminant Meningitis

Emerging Infectious Diseases
We explored the role of commensal Neisseria in the emergence of third-generation cephalosporin-resistant N. meningitidis. Cefotaxime resistance–conferring penA795 was prevalent among commensal Neisseria isolates in Shanghai, China, and was acquired by a

High performance liquid chromatography of natural products. I. Separation of cephalosporin C derivatives and cephalosporin antibiotics; isolation of cephalosporin C from fermentation broth.

The Journal of Antibiotics, 1976
Microbonded propylamine silica with a solvent system containing acetic acid, methanol, acetonitrile and water (2:4:7.5:86.5) is suitable for an efficient separation of mixtures containing several closely related cephem derivatives. The same system with preparative columns was used for the isolation of cephalosporin C directly from the filtered broth of

18‐FDG PET in the Evaluation of Therapeutic Response of Necrotizing Otitis Externa

The Laryngoscope, EarlyView.
PET performed well in assessing the therapeutic response of NEO, with excellent sensitivity but low specificity of visual analysis. A complementary quantitative analysis was useful to distinguish between satisfactory and insufficient partial responses. ABSTRACT Objective The duration of antibiotic treatment for necrotizing otitis externa (NEO) and the ...

Colorimetric determination of Cephalosporin C

BUNSEKI KAGAKU, 1970
セファロスポリンCは,2,4-ジニトロフェニルヒドラジンの過塩素酸溶液と沸騰水浴中で加熱すると,黄色のグリオキサール・ビス2,4-ジニトロフェニルヒドラゾンを生成するから,これを濾取し,テトラメチルアンモニウムヒドロキサイド含有のジメチルホルムアミドで溶解すると,λmaxが615mμにある青色となり,2×10-8～2×10-7mol/mlの範囲でベールの法則を満足し,定量に利用できる.本定量法において,グリオキサールの生成部位が,セファロスポリン母核の6,7位の炭素からであるので,セファロスポリン類および,類似構造のペニシリン類の定量にも利用できることがわかった.

The Evolving Landscape of Immunotoxicity: Charting Mechanisms and Future Strategies for Immune Checkpoint Inhibitor Adverse Events

Med Research, EarlyView.
ABSTRACT The use of immune checkpoint inhibitors (ICIs) has significantly improved the efficacy of cancer therapy, but their associated immune‐related adverse events (irAEs) can severely compromise treatment safety. This review systematically summarizes the core mechanisms underlying irAEs, which include multi‐organ damage resulting from T‐cell ...

Cefoperazone induces esterase B expression by EstR and esterase B enhances cefoperazone activity at the periplasm

International Journal of Medical Microbiology, 2020
The occurrence of antibiotic resistance bacteria has become a major threat to public health. We have recently discovered a transcriptional activator that belongs to MarR family, EstR, and an esterase B (EstB) with a newly proposed de-arenethiolase ...

Food Safety Practices and Foodborne Illness in Italian Pediatric Oncology and Hematology Centers: A Survey on Behalf of the Infectious Disease Working Group of AIEOP

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Food safety practices are widely recommended for pediatric patients with cancer or undergoing hematopoietic stem cell transplantation (HCT) to mitigate foodborne infectious risks. However, specific measures, such as the neutropenic diet (ND) or low‐microbial diet, lack robust evidence and are inconsistently implemented across ...
