Clavulanic Acid 9-24 interferon gamma Homo sapiens 88-97 15987690-4 2005 Unfortunately, the emergence of clavulanic acid-resistant variants of TEM-1 and SHV-1 beta-lactamase significantly compromise the efficacy of this combination.

Clavulanic Acid 176-187 carbapenem-hydrolyzing beta-lactamase KPC-2 Klebsiella pneumoniae 13-18 14742206-9 2004 A beta-lactamase inhibitor test was helpful in distinguishing the two types of resistance but was not definitive since 24% of clinical isolates producing AmpC beta-lactamase had a positive response to clavulanic acid. Clavulanic Acid 201-216 beta-lactamase Escherichia coli 154-158 14638498-11 2003 The kinetic studies revealed that KPC-2 was inhibited by clavulanic acid and tazobactam. Clavulanic Acid 57-72 KPC-2 Escherichia coli 34-39 12843054-3 2003 For 21 of 131 (16%) isolates, the ESBL confirmatory test was positive; i.e., the BMD MICs of ceftazidime or cefotaxime decreased by >/=3 doubling dilutions in the presence of clavulanic acid (CA) or the disk diffusion zone diameters increased by >/=5 mm around ceftazidime or cefotaxime disks in the presence of CA. Clavulanic Acid 178-193 EsbL Escherichia coli 34-38 14534312-2 2003 In TEM-1 and SHV-1, the common class A beta-lactamases, alterations at Ser-130 confer resistance to inactivation by the beta-lactamase inhibitors, clavulanic acid, and tazobactam. Clavulanic Acid 147-162 hypothetical protein Escherichia coli 3-8 12615876-4 2003 Detection of KPC-2 may be a problem for clinical laboratories because in this study it was associated with positive extended-spectrum beta-lactamase (ESBL) confirmation tests (clavulanate-potentiated activities of ceftriaxone, ceftazidime, cefepime and aztreonam). Clavulanic Acid 176-187 beta-lactamase Klebsiella pneumoniae 134-148 12558458-11 2003 Although in in vitro tests ESBLs are inhibited by beta-lactamase inhibitors such as clavulanic acid, the activity of beta-lactam/beta-lactamase inhibitor combination agents is influenced by the bacterial inoculum, dose administration regimen and specific type of ESBL present. Clavulanic Acid 84-99 EsbL Escherichia coli 27-31 12517841-3 2003 ESBL production was confirmed by disk diffusion assay using cefpodoxime (CPD), cefotaxime (CTX), and ceftazidime (CTZ) with and without clavulanate (CLAV). Clavulanic Acid 136-147 EsbL Escherichia coli 0-4 12517841-3 2003 ESBL production was confirmed by disk diffusion assay using cefpodoxime (CPD), cefotaxime (CTX), and ceftazidime (CTZ) with and without clavulanate (CLAV). Clavulanic Acid 149-153 EsbL Escherichia coli 0-4 12435677-8 2002 For high-level or intermediate-level beta-lactamase-producing strains, the existence of a clavulanate concentration threshold of 1.5 to 2 micro g/ml, below which there was no bactericidal activity, was demonstrated. Clavulanic Acid 90-101 beta-lactamase Escherichia coli 37-51 12435677-9 2002 The index of surviving bacteria showed the existence of mixed concentration- and time-dependent actions of amoxicillin (in the presence of clavulanate) which varied as a function of the magnitude of beta-lactamase production by the test strains. Clavulanic Acid 139-150 beta-lactamase Escherichia coli 199-213 11985581-0 2002 ORF6 from the clavulanic acid gene cluster of Streptomyces clavuligerus has ornithine acetyltransferase activity. Clavulanic Acid 14-29 hypothetical protein Escherichia coli 0-4 12445009-10 2002 CONCLUSIONS: For practical reasons, we would recommend use of either the Jarlier test or the commercial cephalosporin disks containing clavulanic acid to screen for ESBL producers. Clavulanic Acid 135-150 EsbL Escherichia coli 165-169 12183230-7 2002 Thus, in addition to the previously characterized clavulanic acid-inhibited extended-spectrum beta-lactamase CGA-1 of Ambler class A, C. gleum produces a very likely chromosome-borne class B beta-lactamase. Clavulanic Acid 50-65 beta-lactamase Escherichia coli 94-108 11959554-8 2002 (iii) NB2001 activity against beta-lactamase-producing E. coli is decreased in the presence of the beta-lactamase inhibitor clavulanic acid.

Clavulanic Acid 124-139 beta-lactamase Escherichia coli 99-113 11985581-2 2002 The orf6 gene of the clavulanic acid biosynthetic gene cluster in S. clavuligerus encodes a protein that shows sequence homology to ornithine acetyltransferase (OAT), the fifth enzyme of the arginine biosynthetic pathway. Clavulanic Acid 21-36 hypothetical protein Escherichia coli 4-8 11870868-8 2002 For instance, the clinically used inhibitor clavulanic acid and the beta-lactamase-resistant beta-lactams moxalactam and imipenem destabilize TEM-1 by over 2.6C (1.2 kcal/mol) in their covalent adducts. Clavulanic Acid 44-59 CD248 molecule Homo sapiens 142-147 11807680-2 2002 Of 33 nonrepetitive clinical isolates, 31 produced a VEB-1-like clavulanic acid-inhibited extended-spectrum beta-lactamase (ESBL). Clavulanic Acid 64-79 Beta lactamase Pseudomonas aeruginosa 108-122 11502506-12 2001 The stepwise mutations that lead to a non-ESBL (SHV-25) and the beta-lactamase (SHV-26) with reduced susceptibility to clavulanic acid are possibly derived from SHV-11 and SHV-1, respectively. Clavulanic Acid 119-134 beta-lactamase Klebsiella pneumoniae 64-78 11327849-5 2001 Results are discussed in relation to the mechanism-based inhibition of class A beta-lactamases by the similar inhibitors sulbactam and clavulanic acid. Clavulanic Acid 135-150 amyloid beta precursor protein Homo sapiens 77-83 11257029-3 2001 The beta-lactamase activity against imipenem and meropenem was inhibited in the presence of clavulanic acid. Clavulanic Acid 92-107 beta-lactamase Klebsiella pneumoniae 4-18 10952583-2 2000 A consistent reduction in the MICs of oxyimino-beta-lactams by at least 3 twofold dilutions in the presence of clavulanic acid confirmed the utility of K. pneumoniae K6 as a quality control strain for extended-spectrum beta-lactamase (ESBL) detection. Clavulanic Acid 111-126 CTX-M-15 Klebsiella pneumoniae 201-233 11036023-6 2000 However, BES-1 differed from CTX-M enzymes by its significant ceftazidime-hydrolyzing activity (k(cat), 25 s(-1)), high affinity for aztreonam (K(i), 1 microM), and lower susceptibility to tazobactam (50% inhibitory concentration [IC(50)], 0.820 microM) than to clavulanate (IC(50), 0.045 microM). Clavulanic Acid 262-273 BES-1 Serratia marcescens 9-14 11114163-2 2001 Natural variants of TEM-1 with increased antibiotic resistance have appeared in response to the use of extended-spectrum beta-lactam antibiotics (e.g., ceftazidime) and beta-lactamase inhibitors (e.g., clavulanic acid).

Clavulanic Acid 104-119 EsbL Escherichia coli 163-167 10741001-7 2000 Since the CAZ-resistance decreased (MIC, 64 micrograms/ml-->0.13 microgram/ml) by the presence of clavulanate (CVA) in this isolate, this strain was speculated to be an extended spectrum beta-lactamase (ESBL) producer at an early stage of infection. Clavulanic Acid 101-112 beta-lactamase Escherichia coli 190-204 10741001-7 2000 Since the CAZ-resistance decreased (MIC, 64 micrograms/ml-->0.13 microgram/ml) by the presence of clavulanate (CVA) in this isolate, this strain was speculated to be an extended spectrum beta-lactamase (ESBL) producer at an early stage of infection. Clavulanic Acid 101-112 EsbL Escherichia coli 206-210 10741001-7 2000 Since the CAZ-resistance decreased (MIC, 64 micrograms/ml-->0.13 microgram/ml) by the presence of clavulanate (CVA) in this isolate, this strain was speculated to be an extended spectrum beta-lactamase (ESBL) producer at an early stage of infection. Clavulanic Acid 114-117 beta-lactamase Escherichia coli 190-204 10741001-7 2000 Since the CAZ-resistance decreased (MIC, 64 micrograms/ml-->0.13 microgram/ml) by the presence of clavulanate (CVA) in this isolate, this strain was speculated to be an extended spectrum beta-lactamase (ESBL) producer at an early stage of infection. Clavulanic Acid 114-117 EsbL Escherichia coli 206-210 11050776-2 2000 These enzymes have arisen by mutation of the genes coding for clavulanate-sensitive, plasmid-mediated beta-lactamases such as TEM-1, TEM-2 and SHV-1. Clavulanic Acid 62-73 hypothetical protein Escherichia coli 126-131 10877515-4 2000 Beta-lactamase production of the clavulanate-resistant strains was further investigated by analytical isoelectric focusing (pI). Clavulanic Acid 33-44 beta-lactamase Escherichia coli 0-14 10877515-7 2000 Beta-lactamase assays revealed that hyperproduction of these enzymes was the predominant mechanism for clavulanate resistance. Clavulanic Acid 103-114 beta-lactamase Escherichia coli 0-14 10423234-0 1999 X-ray structure of the Asn276Asp variant of the Escherichia coli TEM-1 beta-lactamase: direct observation of electrostatic modulation in resistance to inactivation by clavulanic acid.

Clavulanic Acid 198-213 TEM-1 beta-lactamase Escherichia coli 103-123 9990476-8 1999 Addition of the beta-lactamase inhibitor clavulanate completely reversed the inoculum effect in beta-lactamase (TEM-1 and ROB-1) positive strains of H. influenzae with all beta-lactams tested. Clavulanic Acid 41-52 beta-lactamase TEM-1 Haemophilus influenzae 16-30 10573961-8 1999 Recently, the emergence of E. coli strain resistant to combination of amoxycillin and clavulanate, due to hyperproduction of TEM-1 beta-lactamase, was observed. Clavulanic Acid 86-97 TEM-1 beta-lactamase Escherichia coli 125-145 10331993-1 1999 Beta-lactamase inhibitors (clavulanic acid, tazobactam, and sulbactam) greatly enhance the therapeutic efficacy of their partner antibiotics (amoxacillin, ampicillin, piperacillin, and ticarcillin) against common enteric and non-enteric organisms possessing class A beta-lactamases. Clavulanic Acid 27-42 amyloid beta precursor protein Homo sapiens 264-270 10234838-2 1999 Clavulanic acid restored the ceftazidime activity, thus suggesting an extended spectrum beta-lactamase (ESBL). Clavulanic Acid 0-15 EsbL Escherichia coli 104-108 10103192-6 1999 In contrast, amoxicillin susceptibility was not sufficiently restored when 2 micrograms of clavulanate per ml was used, particularly in moderate (mean beta-lactamase activity, 50.8 mU/mg of protein) and high-level (215 mU/mg) TEM-1 beta-lactamase producer isolates. Clavulanic Acid 91-102 TEM-1 beta-lactamase Escherichia coli 226-246 10350372-2 1999 The recent emergence of bacterial strains producing inhibitor-resistant TEM (IRT) enzymes could be related to the frequent use of beta-lactamase inhibitors such as clavulanic acid, sulbactam and tazobactam in hospitals and in general practice. Clavulanic Acid 164-179 MFT2 Homo sapiens 72-75 9990476-8 1999 Addition of the beta-lactamase inhibitor clavulanate completely reversed the inoculum effect in beta-lactamase (TEM-1 and ROB-1) positive strains of H. influenzae with all beta-lactams tested. Clavulanic Acid 41-52 beta-lactamase TEM-1 Haemophilus influenzae 96-110 9990476-8 1999 Addition of the beta-lactamase inhibitor clavulanate completely reversed the inoculum effect in beta-lactamase (TEM-1 and ROB-1) positive strains of H. influenzae with all beta-lactams tested.

Clavulanic Acid 91-106 beta-lactamase Escherichia coli 14-28 7791208-4 1995 The revertant beta-lactamase had the same pI as TEM-1 (5.4) and had restored inhibition by clavulanic acid (ID50 reduced from 4.2 microM to 0.15 microM). Clavulanic Acid 91-106 hypothetical protein Escherichia coli 48-53 7669831-7 1995 The lower detection limits of cefsulodin and clavulinic acid (P 0.05 level) were calculated to be 0.16 and 0.24 microgram ml-1, respectively. Clavulanic Acid 45-60 interleukin 17F Homo sapiens 122-126 7640670-5 1995 The enzyme was as efficiently inhibited by clavulanic acid and tazobactam as the TEM-1 and TEM-2 beta-lactamases but more than the amoxycillin-clavulanic acid-resistant TRC-1 enzyme. Clavulanic Acid 43-58 hypothetical protein Escherichia coli 81-86 7726509-2 1995 These beta-lactamases derived from TEM-1 enzyme focused at pI 5.2 (n = 68) or 5.4 (n = 39) and were very poorly inhibited by clavulanic acid compared with TEM-1 enzyme. Clavulanic Acid 125-140 hypothetical protein Escherichia coli 35-40 7873581-1 1995 Analysis of the three dimensional structure of the class A beta-lactamases shows that Arg-244, a spatially conserved residue important for inactivation by clavulanic acid, is held in place by a hydrogen (H) bond from the residue at 276. Clavulanic Acid 155-170 amyloid beta precursor protein Homo sapiens 57-63 7726509-9 1995 The implication of these novel mutated positions, 165 and 275, in resistance to inactivation by clavulanate was supported by crystallographic data on the TEM-1 enzyme and results of site-directed mutagenesis. Clavulanic Acid 96-107 hypothetical protein Escherichia coli 154-159 1622180-5 1992 Cefaclor, which alone appeared not to bind PBP 2, in combination inhibited PBP 2 binding of clavulanic acid. Clavulanic Acid 92-107 AT695_RS10295 Staphylococcus aureus 75-80 8056282-5 1994 A Met-69-Leu variant of TEM-1, obtained by site-directed mutagenesis, has been described as resistant to clavulanate. Clavulanic Acid 105-116 hypothetical protein Escherichia coli 24-29 8067751-0 1994 Reversal of clavulanate resistance conferred by a Ser-244 mutant of TEM-1 beta-lactamase as a result of a second mutation (Arg to Ser at position 164) that enhances activity against ceftazidime. Clavulanic Acid 12-23 TEM-1 beta-lactamase Escherichia coli 68-88 8257123-0 1993 Characterization of a new TEM-type beta-lactamase resistant to clavulanate, sulbactam, and tazobactam in a clinical isolate of Escherichia coli. Clavulanic Acid 63-74 beta-lactamase Escherichia coli 35-49 8257123-5 1993 The inhibitory effects of clavulanate, sulbactam, and tazobactam on the TEM-1 enzyme were substantially decreased in comparison with those on IRT-3, as indicated by the 50% inhibitory concentrations. Clavulanic Acid 26-37 hypothetical protein Escherichia coli 72-77 8262865-6 1993 Thus, the MICs of piperacillin or amoxycillin with tazobactam or clavulanate were only two- to four-fold higher for beta-lactamase producers than non-producers at low inocula (10(4) cfu), but this differential increased to 6- to 16-fold at high inocula (10(6) cfu). Clavulanic Acid 65-76 beta-lactamase Staphylococcus aureus 116-130 8517725-7 1993 However, clavulanate and cloxacillin, serine beta-lactamase inhibitors, inhibited the enzyme activity competitively (Kis = 5.60 and 0.35 microM, respectively). Clavulanic Acid 9-20 beta-lactamase Klebsiella pneumoniae 45-59 8067751-1 1994 The mutation of Arg-244 to Ser (Arg-244-->Ser mutation) in the TEM-1 beta-lactamase has been shown to produce resistance to inactivation by clavulanate in the mutant enzyme and resistance to ampicillin plus clavulanate in a strain of Escherichia coli producing this enzyme. Clavulanic Acid 143-154 TEM-1 beta-lactamase Escherichia coli 66-86 8067751-1 1994 The mutation of Arg-244 to Ser (Arg-244-->Ser mutation) in the TEM-1 beta-lactamase has been shown to produce resistance to inactivation by clavulanate in the mutant enzyme and resistance to ampicillin plus clavulanate in a strain of Escherichia coli producing this enzyme. Clavulanic Acid 210-221 TEM-1 beta-lactamase Escherichia coli 66-86 8067751-5 1994 The doubly mutated derivative of the TEM-1 enzyme (Ser-164/Ser-244) retains the characteristics of the Ser-164 mutant enzyme, i.e., enhanced activity against ceftazidime and sensitivity to inactivation by clavulanate. Clavulanic Acid 205-216 hypothetical protein Escherichia coli 37-42 8067751-7 1994 Thus, the Arg-164-->Ser mutation in the TEM-1 beta-lactamase suppresses the effect of the Arg-244-->Ser mutation which, by itself, reduces the sensitivity of the enzyme to inactivation by clavulanate. Clavulanic Acid 194-205 TEM-1 beta-lactamase Escherichia coli 43-63 8031044-8 1994 In particular, clavulanic acid was 60 and 580 times more potent than sulbactam against TEM-1 and SHV-1, respectively, currently the two most clinically prevalent gram-negative plasmid-mediated beta-lactamases. Clavulanic Acid 15-30 CD248 molecule Homo sapiens 87-92 8203843-7 1994 TEM-1 beta-lactamase activity was inhibited in vitro by clavulanic acid, but not totally, with approximately 2% of the initial activity remaining at 2 micrograms/ml and 0.4% remaining at 8 micrograms/ml. Clavulanic Acid 56-71 TEM-1 beta-lactamase Escherichia coli 0-20 7821300-4 1994 Novel clavulanate-sensitive extended-spectrum beta-lactamases deriving from other class A enzymes (e.g. MEN-1 from beta la OXY, OXA-11 in Pseudomonas aeruginosa from PSE-2) have been reported. Clavulanic Acid 6-17 menin 1 Homo sapiens 104-109 8047854-10 1994 By adding a beta-lactamase inhibitor (clavulanic acid) to amoxycillin, or using second-generation cephalosporins, clearance can be achieved. Clavulanic Acid 38-53 Beta lactamase Pseudomonas aeruginosa 12-26 8262865-2 1993 Tazobactam and clavulanate inhibit the enzyme, but beta-lactamase producers remained substantially less susceptible than non-producers to piperacillin/tazobactam and co-amoxiclav in disc tests. Clavulanic Acid 15-26 beta-lactamase Staphylococcus aureus 51-65 8396624-4 1993 However, strains expressing class A beta-lactamase were susceptible to cefodizime in combination with clavulanic acid. Clavulanic Acid 102-117 amyloid beta precursor protein Homo sapiens 34-40 8392995-5 1993 Both beta-lactamases have the same pI at 5.25 and have similar ID50 values for the beta-lactamase inhibitors clavulanic acid, sulbactam and tazobactam. Clavulanic Acid 109-124 beta-lactamase Escherichia coli 5-19 8432315-3 1993 Forty-six percent of the TEM-1 producing strains were able to transfer this resistance to E. coli J62-2 at 37 degrees C. Analysis of the resulting transconjugants revealed that the degree of resistance to amoxycillin and amoxycillin in combination with clavulanic acid was related to the specific activity of the TEM-1 beta-lactamase.

Clavulanic Acid 79-94 beta-lactamase Escherichia coli 36-50 1316862-6 1992 Its most significant difference is that it is inhibited by clavulanic acid 100-fold less efficiently than the TEM-1 enzyme. Clavulanic Acid 59-74 hypothetical protein Escherichia coli 110-115 1316862-8 1992 This is the first report of a clinical bacterium carrying a TEM-enzyme that confers resistance to clavulanic acid combinations and we have designated the beta-lactamase as TRC-1.

Clavulanic Acid 64-79 CD248 molecule Homo sapiens 189-193 1818798-0 1991 Antibacterial activities of amoxicillin alone and in combination with clavulanic acid correlated with beta-lactamase production. Clavulanic Acid 70-85 beta-lactamase TEM-1 Haemophilus influenzae 102-116 1818798-6 1991 For beta-lactamase producers, clavulanic acid decreased the MICs of amoxicillin prominently in strains of Neisseria gonorrhoeae, Haemophilus influenzae, Escherichia coli, K. pneumoniae, P. mirabilis, Enterobacter cloacae and Bacteroides fragilis, when combining clavulanic acid with amoxicillin in the ratio of 1:2. Clavulanic Acid 30-45 beta-lactamase Neisseria gonorrhoeae 4-18 1818798-6 1991 For beta-lactamase producers, clavulanic acid decreased the MICs of amoxicillin prominently in strains of Neisseria gonorrhoeae, Haemophilus influenzae, Escherichia coli, K. pneumoniae, P. mirabilis, Enterobacter cloacae and Bacteroides fragilis, when combining clavulanic acid with amoxicillin in the ratio of 1:2. Clavulanic Acid 262-277 beta-lactamase Neisseria gonorrhoeae 4-18 1769944-4 1991 However, the TEM-1 and TEM-2 producers were resistant in disc tests to ampicillin/sulbactam and amoxycillin/clavulanic acid, and showed intermediate susceptibility to ticarcillin/clavulanic acid.
