Production of β-lactamase inhibitors by Streptomyces species
(2018-09-01)
β-Lactamase inhibitors have emerged as an effective alternative to reduce the effects of resistance against β-lactam antibiotics. The Streptomyces genus is known for being an exceptional natural source of antimicrobials ...
Evaluation of different media for the production of cephalosporins by Streptomyces clavuligerus ATCC 27064
(Brazilian Archives of Biology and Technology, 2012-12-01)
The aim of this work was to compare the composition of a complex and soluble culture medium to eight other media described in the literature through the batch cultivation in a conventional bench-scale bioreactor for the ...

Short communication: β-Lactam resistance and vancomycin heteroresistance in Staphylococcus spp. isolated from bovine subclinical mastitis
(2017-08-01)
The use of antimicrobial agents has led to the emergence of resistant bacterial strains over a relatively short period. Furthermore, Staphylococcus spp. can produce β-lactamase, which explains the survival of these strains ...
A Natural Deep Eutectic Solvent Formulated to Stabilize β-Lactam Antibiotics
(2018)
β-lactam antibiotics, such as penicillin share a very unstable chemical structure. In water-based solutions, such as those used for clinical applications, the β-lactam ring is readily opened due to a nucleophilic or ...
Antimicrobial Resistance Patterns and Dynamics of Extended-Spectrum beta-Lactamase-Producing Uropathogenic Escherichia coli in Cusco, Peru
(MDPI, 2021)
Urinary tract infections (UTIs) are a common human infection. Antibiotic resistance in extended-spectrum beta-lactamase (ESBL)-producing uropathogenic E. coli (UPEC) is a major therapeutic challenge due to limited treatment ...
