Supra and subgingival application of antiseptics or antibiotics during periodontal therapy
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Small Changes in Hydration Determine Cephalosporinase Activity of OXA-48 β-Lactamases
, 2020 β-lactamase mediated antibiotic resistance threatens treatment of bacterial infections. OXA-48 enzymes are clinically important class D serine β-lactamases (SBLs) that confer resistance to most β-lactam antibiotics, including carbapenems. However, OXA-48

Some aspects of general characteristic and classification of bacterial β-lactamases
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2009 Main structural and functional groups of bacterial β-lactamases are cited in the data review. Modern systems of classification, which was based on spectra of activity, sensitivity to inhibitors and peculiarities of molecular structure are described.

Clinical and Research Journal in Internal Medicine, 2021 Background: β-lactamase is an enzyme that plays a role in the occurrence of antibiotic resistance against Methicillin-resistant Staphylococcus aureus (MRSA) bacteria. Viscosin is a lipopeptide biosurfactant produced by the Pseudomonas group bacteria.

Fungal Lactamases: Their Occurrence and Function
Frontiers in Microbiology, 2017 Fungi are absorptive feeders and thus must colonize and ramify through their substrate to survive. In so doing they are in competition, particularly in the soil, with myriad microbes.

Activity fingerprinting of AMR β-lactamase towards a fast and accurate diagnosis
Frontiers in Cellular and Infection Microbiology, 2023 Antibiotic resistance has become a serious threat to global public health and economic development. Rapid and accurate identification of a patient status for antimicrobial resistance (AMR) are urgently needed in clinical diagnosis.

Expression of β-lactamase inCoxiella burnetiitransformants [PDF]
FEMS Microbiology Letters, 2000 Coxiella burnetii can be transformed to ampicillin resistance by electroporation with plasmids encoding beta-lactamase. However, non-plasmid emergence of resistance to ampicillin also develops. To validate the usefulness of the bla gene marker for selection and detection, transformed C.

Advanced Science, EarlyView.Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...
