Genomic analysis of bifunctional Class C-Class D β-lactamases in environmental bacteria
Memorias do Instituto Oswaldo Cruz, 2018 β-lactamases, which are found in several bacterial species and environments, are the main cause of resistance to β-lactams in Gram-negative bacteria. In 2009, a protein (LRA-13) with two β-lactamase domains (one class C domain and one class D domain) was

Could β-Lactam Antibiotics Block Humoral Immunity?
Frontiers in Immunology, 2021 It has been reported that treatment with β-lactam antibiotics induces leukopenia and candidemia, worsens the clinical response to anticancer immunotherapy and decreases immune response to vaccination.

Periodontology 2000, EarlyView., 2023 Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

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 ...

Identification of Family Specific Fingerprints in β-Lactamase Families
The Scientific World Journal, 2014 Beta-lactamases are a superfamily of enzymes which degrade the β-lactam class of antibiotics. They are produced endogenously by the bacterial cells, which when exposed to the β-lactam class of antibiotics inactivate them by cleaving the β-lactam ring ...

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.
