β-Lactam Antibiotics Renaissance.
Since the 1940s β-lactam antibiotics have been used to treat bacterial infections. However, emergence and dissemination of β-lactam resistance has reached the point where many marketed β-lactams no longer are clinically effective. The increasing prevalence of multidrug-resistant bacteria and the progressive withdrawal of pharmaceutical companies from antibiotic research have evoked a strong rea...
متن کاملDegradation of β-lactam antibiotics
Recent developments in the chemistry and biology of βlactam antibiotics which culminated with the introduction of several clinically useful classical and nonclassical β-lactams have been most thrilling and highly rewarding. While this review touches upon the historical development of β-lactams and their reactivity in a nutshell, it provides an overview of various aspects of chemical and enzymat...
متن کاملOccupational allergy to β-lactam antibiotics
Background Contact urticaria in atopic patients was described by Hannuksela [1], among others, in 1980. It generally appears within 30 min of allergen contact and, in the majority of cases, is restricted to the areas of contact; however, local spread and generalized urticaria in the sense of anaphylaxis are seen. Allergic rhinoconjunctivitis and asthma may also subsequently occur [2]. Von Krogh...
متن کاملEscherichia coli mutants tolerant to beta-lactam antibiotics.
Two types of Escherichia coli mutants tolerant to beta-lactam antibiotics were isolated. One is E. coli chi2452, which showed a tolerant response against beta-lactam antibiotics when grown at 42 degrees C, and the others are the mutants C-80 and C-254, selected from mutagenized E. coli chi1776 by cycles of exposure to ampicillin, cephaloridine, and starvation of the nutritionally required diami...
متن کاملParadoxical Hypersusceptibility of Drug-resistant Mycobacteriumtuberculosis to β-lactam Antibiotics
Mycobacterium tuberculosis (M. tuberculosis) is considered innately resistant to β-lactam antibiotics. However, there is evidence that susceptibility to β-lactam antibiotics in combination with β-lactamase inhibitors is variable among clinical isolates, and these may present therapeutic options for drug-resistant cases. Here we report our investigation of susceptibility to β-lactam/β-lactamase ...
