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 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 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 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 ...
متن کاملDivergent mechanisms for passive pneumococcal resistance to β-lactam antibiotics in the presence of Haemophilus influenzae.
BACKGROUND Otitis media, for which antibiotic treatment failure is increasingly common, is a leading pediatric public health problem. METHODS In vitro and in vivo studies using the chinchilla model of otitis media were performed using a β-lactamase-producing strain of nontypeable Haemophilus influenzae (NTHi 86-028NP) and an isogenic mutant deficient in β-lactamase production (NTHi 86-028NP b...
