Efflux pump, the masked side of beta-lactam resistance in Klebsiella pneumoniae clinical isolates. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND: Beta-lactamase production and porin decrease are the well-recognized mechanisms of acquired beta-lactam resistance in Klebsiella pneumoniae isolates. However, such mechanisms proved to be absent in K.

The Beta-Lactam Resistome Expressed by Aerobic and Anaerobic Bacteria Isolated from Human Feces of Healthy Donors

open access: yesPharmaceuticals, 2021
Antibiotic resistance is a major health problem worldwide, causing more deaths than diabetes and cancer. The dissemination of vertical and horizontal antibiotic resistance genes has been conducted for a selection of pan-resistant bacteria.

Studies on beta-Lactams

open access: yesZeitschrift für Naturforschung B, 1969
Since the discovery 11 of the activating effect of the N- (p-Nitro-phenyl)-group on the methine hydrogen of halogenacetamino esters, it has been found that the p-Acetyl-phenyl and m-Nitro-phenyl groups exert a similar effect. It has been shown that the delocalisation of the N-non-bonded electrons across the orbitals of the N-Aryl substituent is the ...

A Study of Elevated Interleukin-8 (CXCL8) Detection of Leukocyte Migration Inhibitory Activity in Patients Allergic to Beta-Lactam Antibiotics

open access: yesAllergology International, 2011
Background: The leukocyte migration test (LMT) is effective in identifying the causative drug in drug allergies. Both leukocyte migration activating activity (LMAA) and leukocyte migration inhibitory activity (LMIA) are involved in the development of ...
