Interaction between Class B Beta-Lactamases and Suicide Substrates of Active-Site Serine Beta-Lactamases [PDF]

, 1999
peer reviewedThe most widely used inactivators of active-site serine beta-lactamases behave as substrates of four class B metallo-beta-lactamases, but the efficiency of the catalytic process can vary by several orders of magnitude.

Functional metagenomic analysis reveals rivers are a reservoir for diverse antibiotic resistance genes [PDF]

, 2014
The environment harbours a significant diversity of uncultured bacteria and a potential source of novel and extant resistance genes which may recombine with clinically important bacteria disseminated into environmental reservoirs.

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

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.

Screening of Epidemiologically Significant Mechanisms of Antibiotics to β-Lactams in Enterobacteriaceae - Pathogens of Zoonoses

Journal of Pure and Applied Microbiology, 2021
Among the acquired mechanisms of resistance to antibiotics of microorganisms, the production of beta-lactamases, enzymes that inactivate penicillins, cephalosporins, carbapenems, and monobactams, is widespread.

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 ...

Dutch patients, retail chicken meat and poultry share the same ESBL genes, plasmids and strains

, 2011
Intestinal carriage of extended-spectrum beta-lactamase (ESBL) -producing bacteria in food-producing animals and contamination of retail meat may contribute to increased incidences of infections with ESBL-producing bacteria in humans.

Explaining Adherence Success in Sub-Saharan Africa: An Ethnographic Study. [PDF]

, 2009
Individuals living with HIV/AIDS in sub-Saharan Africa generally take more than 90% of prescribed doses of antiretroviral therapy (ART). This number exceeds the levels of adherence observed in North America and dispels early scale-up concerns that ...

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

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 ...
