The .BETA.-lactamases of genus Bacteroides.
The Journal of Antibiotics, 1983 Two hundred anaerobic isolates from clinical specimens were examined for beta-lactamase production by Nitrocefin methodology. Altogether, 77 strains were beta-lactamase producers. Organisms belonging to Bacteroides melaninogenicus group, i.e., B. intermedius and B.

Boronic Acid Inhibitors of β‐Lactamases: A Promising Strategy Against Antimicrobial Resistance
Medicinal Research Reviews, EarlyView.ABSTRACT The rise of antimicrobial resistance (AMR) poses a critical threat to global health, mostly due to the proliferation of β‐lactamases, a class of enzymes responsible for the inactivation of β‐lactam antibiotics. Among the most promising strategies to restore β‐lactam efficacy is the use of β‐lactamase inhibitors (BLIs), with boronic acid ...

Nature Communications, 2020 Beta-lactam antibiotics and beta-lactamase inhibitors compete for the same binding site on beta-lactamases; thus, mutations that increase beta-lactamase activity likely increase also susceptibility to the inhibitor. Here, Russ et al.

Small Methods, EarlyView.A filtration‐assisted SERS platform integrating in situ gold growth within the bacterial microenvironment enables rapid and highly sensitive detection of low‐level bacteria in complex biological matrices. By overcoming hotspot–bacteria mismatch, the platform simultaneously achieves selective bacterial identification and rapid antimicrobial ...

Microbiology SpectrumGram-negative bacilli-producing beta-lactamases are major causes of difficult-to-treat infections, especially the AmpC, extended-spectrum beta-lactamases (ESBL), and carbapenemase types. Their spread within and outside hospital settings demands effective

Extended-spectrum beta-lactamases: the European experience
, 2001 Extended-spectrum beta-lactamases mediate resistance to cephalosporin antibiotics and were first discovered in Europe in the early 1980s. They have become a widespread problem, particularly in Klebsiella pneumoniae, but increasingly in non-typhoid ...

Veterinary Record, EarlyView.Abstract Background Gram‐negative ESKAPE organisms are an emerging threat in veterinary medicine that also have zoonotic potential. However, little is known about the prevalence and risks of these organisms in pet food. We present the incidental finding of gram‐negative ESKAPE organisms within samples of raw meat diets for dogs in the United Kingdom ...

Integrative Zoology, EarlyView.ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first
