Cefotaxime 185-195 hypothetical protein Escherichia coli 45-50 9189637-7 1997 We demonstrated this in Escherichia coli strains harbouring TEM-1, TEM-12 and TEM-10 beta-lactamases challenged by cefotaxime, and also Streptococcus pneumoniae strains with various levels of penicillin resistance challenged by amoxicillin or cefotaxime. Cefotaxime 115-125 hypothetical protein Escherichia coli 60-65 34145657-5 2021 Under low mistranslation rates, different evolving TEM-1 populations ascend the same high cefotaxime-resistance peak, which requires three canonical DNA mutations. Cefotaxime 90-100 hypothetical protein Escherichia coli 51-56 35052944-6 2022 Results show that cefotaxime is the preferred inducer for CTX-M-15 and amoxicillin for TEM-1, whereas oxacillin for OXA-2. Cefotaxime 18-28 hypothetical protein Escherichia coli 87-92 2692515-4 1989 The beta-lactamase efficiently hydrolyzed cefotaxime and ceftriaxone but only moderately hydrolyzed ceftazidime and was inhibited by clavulanate and sulbactam (1 microM) and by anti-TEM-1 and anti-TEM-2 sera. Cefotaxime 42-52 hypothetical protein Escherichia coli 182-187 2661324-4 1989 However, the TEM-E1 enzyme differs from TEM-1 by its low rates and efficiency of hydrolysis for ceftazidime and cefotaxime, TEM-E1 has similar efficiency of hydrolysis values for ceftazidime and cefotaxime, but only confers resistance to ceftazidime. Cefotaxime 112-122 hypothetical protein Escherichia coli 40-45 28524864-3 2017 Here we evolve the antibiotic resistance protein TEM-1 towards resistance on the antibiotic cefotaxime in an Escherichia coli strain with a high mistranslation rate. Cefotaxime 92-102 hypothetical protein Escherichia coli 49-54 28524864-4 2017 TEM-1 populations evolved in such strains endow host cells with a general growth advantage, not only on cefotaxime but also on several other antibiotics that ancestral TEM-1 had been unable to deactivate. Cefotaxime 104-114 hypothetical protein Escherichia coli 0-5 35134504-0 2022 Efficacy of piperacillin-tazobactam and cefotaxime against Escherichia coli hyperproducing TEM-1 in a mouse peritonitis infection model. Cefotaxime 40-50 hypothetical protein Escherichia coli 91-96
