The Mechanisms of Catalysis by Metallo β-Lactamases [PDF]
Class B β-lactamases or metallo-β-lactamases (MBLs) require zinc ions to catalyse the hydrolysis of β-lactam antibiotics such as penicillins, cephalosporins, carbapenems, and cephamycins.

Prevalence of multiresistant gram-negative organisms in a tertiary hospital in Mwanza, Tanzania. [PDF]
\ud Antimicrobial resistance is fast becoming a global concern with rapid increases in multidrug-resistant Gram negative organisms. The prevalence of extended spectrum beta-lactamase (ESBL)-producing clinical isolates increases the burden on implementing

Beta-lactam resistance in Campylobacter [PDF]
Resistance to β-lactam antibiotics in Campylobacter is often associated with the production of a β-lactamase; to date the genomically encoded bla\(_{OXA-61}\) and the closely related cj0299 are the only described β-lactamase genes of Campylobacter ...

Exploring Protein Sequence Space Using Computationally Directed Recombination [PDF]
Evolution has provided us with many protein sequences. However, these sequences represent a very small fraction of the possible sequences. In the laboratory, scientists have explored areas of sequence space not represented by natural proteins both to ...

Bacterial beta-lactamases are responsible for resistance to beta-lactams, the most important family of antibiotics. Here, the authors reveal cyclic boronate inhibitors that are active against both serine- and metallo-beta-lactamases and represent a ...

Epidemiologia molecolare di Klebsiella pneumoniae produttore di beta-lattamasi ad ampio spettro (ESBL) circolante in una Terapia Intensiva Neonatale [PDF]
The molecular epidemiology of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae was investigated in the neonatal intensive care unit (NICU) of a university hospital in Italy from September 2002 to December 2004, when 233 ...

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
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 ...
