Aztreonam 120-129 metallo-beta-lactamase NDM-1 Klebsiella pneumoniae 4-12 25059447-4 2014 Multilocus sequence typing (MLST) revealed that all NDM-1-producing K. pneumoniae isolates belonged to sequence type 340 (ST340) and harboured genes encoding additional beta-lactamases; presence of the bla(CTX-M-1-like) gene correlated with aztreonam resistance, whilst its absence correlated with susceptibility. Aztreonam 241-250 NDM-1 Klebsiella pneumoniae 52-57 24789185-0 2014 Incidence of extended-spectrum-beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae isolates that test susceptible to cephalosporins and aztreonam by the revised CLSI breakpoints. Aztreonam 152-161 EsbL Escherichia coli 13-45 24789185-1 2014 The incidence of aztreonam and cephalosporin susceptibility, determined using the revised CLSI breakpoints, for extended-spectrum-beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae isolates was evaluated. Aztreonam 17-26 EsbL Escherichia coli 112-144 24789185-1 2014 The incidence of aztreonam and cephalosporin susceptibility, determined using the revised CLSI breakpoints, for extended-spectrum-beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae isolates was evaluated. Aztreonam 17-26 EsbL Escherichia coli 146-150 24789185-2 2014 Our analysis showed that results for aztreonam and/or >=1 cephalosporin were reported as susceptible or intermediate for 89.2% of ESBL-producing E coli isolates (569/638 isolates) and 67.7% of ESBL-producing K. pneumoniae isolates (155/229 isolates). Aztreonam 37-46 EsbL Escherichia coli 133-137 24789185-2 2014 Our analysis showed that results for aztreonam and/or >=1 cephalosporin were reported as susceptible or intermediate for 89.2% of ESBL-producing E coli isolates (569/638 isolates) and 67.7% of ESBL-producing K. pneumoniae isolates (155/229 isolates). Aztreonam 37-46 EsbL Escherichia coli 196-200 19664245-0 2009 In vitro antimicrobial effects of aztreonam, colistin, and the 3-drug combination of aztreonam, ceftazidime and amikacin on metallo-beta-lactamase-producing Pseudomonas aeruginosa. Aztreonam 34-43 Beta lactamase Pseudomonas aeruginosa 132-146 24033858-4 2013 MICs to beta-lactams in E. coli W4573 and its acrAB mutant strain increased 1- to 500-fold (MIC from 0.125 to 64 mug mL(-1) of aztreonam) in the bla(KPC-2a), bla(KPC-2b), and bla(KPC-2c) transformants compared with the cloning vector alone. Aztreonam 127-136 TEM beta-lactamase Klebsiella pneumoniae 145-148 24033858-4 2013 MICs to beta-lactams in E. coli W4573 and its acrAB mutant strain increased 1- to 500-fold (MIC from 0.125 to 64 mug mL(-1) of aztreonam) in the bla(KPC-2a), bla(KPC-2b), and bla(KPC-2c) transformants compared with the cloning vector alone. Aztreonam 127-136 TEM beta-lactamase Klebsiella pneumoniae 158-161 24033858-4 2013 MICs to beta-lactams in E. coli W4573 and its acrAB mutant strain increased 1- to 500-fold (MIC from 0.125 to 64 mug mL(-1) of aztreonam) in the bla(KPC-2a), bla(KPC-2b), and bla(KPC-2c) transformants compared with the cloning vector alone. Aztreonam 127-136 TEM beta-lactamase Klebsiella pneumoniae 158-161 19664245-0 2009 In vitro antimicrobial effects of aztreonam, colistin, and the 3-drug combination of aztreonam, ceftazidime and amikacin on metallo-beta-lactamase-producing Pseudomonas aeruginosa. Aztreonam 85-94 Beta lactamase Pseudomonas aeruginosa 132-146 19664245-6 2009 RESULTS: Bacteriostatic effects after 6 hours of drug exposure were observed in 12 strains (52.2%) of 23 strains of metallo-beta-lactamase-producing P. aeruginosa with 48 mg/l aztreonam, in 19 strains (82.6%) with the 3-drug combination of 16 mg/l aztreonam, 16 mg/l ceftazidime, and 4 mg/l amikacin, and in 23 strains (100%) with 2 mg/l colistin. Aztreonam 176-185 Beta lactamase Pseudomonas aeruginosa 124-138 19664245-8 2009 CONCLUSION: Evaluation of in vitro antimicrobial effects on metallo-beta-lactamase-producing P. aeruginosa revealed relatively good effects of the 3-drug combination of aztreonam, ceftazidime and amikacin and marked effects of colistin. Aztreonam 169-178 Beta lactamase Pseudomonas aeruginosa 68-82 19258280-4 2009 The inactivation of the mexB gene (which codes for the RND transporter MexB) in the 11 selected strains showed that the Tic(hs) phenotype was due to a mutational or functional loss of function of MexAB-OprM, the multidrug efflux system known to contribute to the natural resistance of P. aeruginosa to beta-lactams (e.g., ticarcillin and aztreonam), fluoroquinolones, tetracycline, and novobiocin. Aztreonam 338-347 multidrug resistance protein MexB Pseudomonas aeruginosa PAO1 24-28 19258280-4 2009 The inactivation of the mexB gene (which codes for the RND transporter MexB) in the 11 selected strains showed that the Tic(hs) phenotype was due to a mutational or functional loss of function of MexAB-OprM, the multidrug efflux system known to contribute to the natural resistance of P. aeruginosa to beta-lactams (e.g., ticarcillin and aztreonam), fluoroquinolones, tetracycline, and novobiocin. Aztreonam 338-347 multidrug resistance protein MexB Pseudomonas aeruginosa PAO1 71-75 18692340-3 2008 Ninety-one percent of laboratories recognized all ESBL producers correctly, and therefore, low error rates were observed when testing cephalosporins and aztreonam. Aztreonam 153-162 EsbL Escherichia coli 50-54 19388560-7 2009 Among the ESBL-producing isolates, the sensitivity was from 3.3% to 61.5% for ampicillin to aztreonam. Aztreonam 92-101 EsbL Escherichia coli 10-14 18079018-5 2008 VIM-2-positive strains were mostly from urine samples and clinical data suggest that in the absence of therapeutic guidelines, piperacillin-tazobactam or aztreonam may be a reliable choice for treating infections with MBL-producing strains. Aztreonam 154-163 VIM-2 Pseudomonas aeruginosa 0-5 18644957-3 2008 The bla(VIM-13)-producing isolate showed resistance to all beta-lactams (except aztreonam), gentamicin, tobramycin, and ciprofloxacin. Aztreonam 80-89 Beta lactamase Pseudomonas aeruginosa 4-7 18184647-1 2008 OBJECTIVES: Twenty-four of 209 oxyimino-cephalosporin- and/or aztreonam-resistant Enterobacteriaceae collected around Bolzano had reduced susceptibility or resistance to carbapenems and gave positive metallo-beta-lactamase (MBL) tests. Aztreonam 62-71 NDM-1 Escherichia coli 200-222 18184647-1 2008 OBJECTIVES: Twenty-four of 209 oxyimino-cephalosporin- and/or aztreonam-resistant Enterobacteriaceae collected around Bolzano had reduced susceptibility or resistance to carbapenems and gave positive metallo-beta-lactamase (MBL) tests. Aztreonam 62-71 NDM-1 Escherichia coli 224-227 18379184-10 2008 Aztreonam and ciprofloxacin were then intravenously administered at doses of 4 g/day and 600 mg/day, respectively, resulting in the alleviation of fever in the patient as well as a decrease in CRP and disappearance of MDRP isolates from urine on day 67; that is, MDRP infection was consequently well controlled. Aztreonam 0-9 C-reactive protein Homo sapiens 193-196 18184647-9 2008 Six MBL producers were aztreonam-susceptible; the 18 aztreonam-resistant isolates had co-resident extended-spectrum beta-lactamases. Aztreonam 23-32 NDM-1 Escherichia coli 4-7 16678993-4 2006 High rates of very major errors (up to 56%) were observed for ESBL producers when testing cephalosporins and aztreonam, especially in the case of CTX-M-1-producing Escherichia coli and TEM-52-producing Proteus mirabilis. Aztreonam 109-118 EsbL Escherichia coli 62-66 18059098-9 2008 Over 90% of ESBL isolates showed resistance to aztreonam and cephalosporins. Aztreonam 47-56 EsbL Escherichia coli 12-16 17223016-0 2007 Comparative in vitro killing of carbapenems and aztreonam against Klebsiella pneumoniae producing VIM-1 metallo-beta-lactamase. Aztreonam 48-57 beta-lactamase Klebsiella pneumoniae 112-126 15815007-4 2005 The strains were screened for the production of extended-spectrum beta-lactamase (ESBL) by the double-disk synergy test using a disk of amoxicillin-clavulanic acid with disks of the extended-spectrum cephalosporins and aztreonam. Aztreonam 219-228 EsbL Escherichia coli 48-80 15629222-4 2005 The ESBL-positive K. pneumoniae isolates were resistant to aztreonam, ceftazidime, aminoglycosides, and trimethoprim/sulfamethoxazole and susceptible to ciprofloxacin and tetracycline. Aztreonam 59-68 CTX-M-15 Klebsiella pneumoniae 4-8 15743578-1 2005 INTRODUCTION: In the last years, we have verified the increasing emergence of bacteria, specially Escherichia coli, that produce expanded spectrum beta-lactamases (ESBL), enzymes which confer resistance to all cephalosporins (except cephamycins) and aztreonam. Aztreonam 250-259 EsbL Escherichia coli 164-168 12951239-7 2003 Clavulanic acid had no inhibitory effect on Mox-1 (K(m)=30.2 mM), however aztreonam behaved as an inhibitor of Mox-1 (K(i)=2.85 microM). Aztreonam 74-83 mesenchyme homeobox 1 Homo sapiens 111-116 15155242-1 2004 A clinical strain of Escherichia coli isolated from pleural liquid with high levels of resistance to cefotaxime, ceftazidime, and aztreonam harbors a novel CTX-M gene (bla(CTX-M-32)) whose amino acid sequence differs from that of CTX-M-1 by a single Asp240-Gly substitution. Aztreonam 130-139 beta-lactamase Escherichia coli 168-171 15155242-1 2004 A clinical strain of Escherichia coli isolated from pleural liquid with high levels of resistance to cefotaxime, ceftazidime, and aztreonam harbors a novel CTX-M gene (bla(CTX-M-32)) whose amino acid sequence differs from that of CTX-M-1 by a single Asp240-Gly substitution. Aztreonam 130-139 CTX-M-1 Escherichia coli 230-237 14638498-7 2003 The bla(KPC-2) determinant was cloned in E. coli and conferred resistance to imipenem, meropenem, extended-spectrum cephalosporins, and aztreonam. Aztreonam 136-145 KPC-2 Escherichia coli 8-13 14638498-9 2003 Hydrolysis studies showed that purified KPC-2 hydrolyzed not only carbapenems but also penicillins, cephalosporins, and aztreonam. Aztreonam 120-129 KPC-2 Escherichia coli 40-45 12909725-7 2003 We demonstrate that our error-prone Pol I can be used to generate enzymes with distinct properties by generating TEM-1 beta-lactamase mutants able to hydrolyze a third-generation lactam antibiotic, aztreonam. Aztreonam 198-207 TEM-1 beta-lactamase Escherichia coli 113-133 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). Aztreonam 253-262 carbapenem-hydrolyzing beta-lactamase KPC-2 Klebsiella pneumoniae 13-18 12507831-11 2003 Among Enterobacter spp., resistance (MIC>or=32 mg/l) to aztreonam, ceftazidime and ceftriaxone ranged from 12.3 to 21.2% over the 4 years, whereas resistance in Klebsiella (MIC>or=2 mg/l) ranged from 5.9 to 6.8%. Aztreonam 59-68 histocompatibility minor 13 Homo sapiens 19-22 12532575-6 2002 Isolates resistant to cefpodoxime and aztreonam were considered as ESBL phenotype, indicating ESBL production. Aztreonam 38-47 EsbL Escherichia coli 67-71 12935353-2 2003 Ceftazidime and aztreonam enhanced TNF-alpha secretion from macrophages stimulated with E. coli; however, imipenem does not alter either the kinetics or magnitude of TNF-alpha in E. coli-treated macrophages. Aztreonam 16-25 tumor necrosis factor Mus musculus 35-44 12935353-6 2003 Both ceftazidime and aztreonam enhanced LPS release from E. coli in comparison to low-level LPS release from imipenem-treated bacteria, consistent with observed differences in TNF-alpha release. Aztreonam 21-30 tumor necrosis factor Mus musculus 176-185 12532575-6 2002 Isolates resistant to cefpodoxime and aztreonam were considered as ESBL phenotype, indicating ESBL production. Aztreonam 38-47 EsbL Escherichia coli 94-98 12532575-14 2002 Resistance to both cefpodoxime and aztreonam was found in 25% isolates suggesting ESBL production. Aztreonam 35-44 EsbL Escherichia coli 82-86 11376058-7 2001 Thus, it is clinically important to detect ESBL production by klebsiellae or E. coli even when cephalosporin MICs are in the susceptible range (<or = 8 microg/ml) and to report ESBL-producing organisms as resistant to aztreonam and all cephalosporins (with the exception of cephamycins). Aztreonam 221-230 EsbL Escherichia coli 43-47 11929691-8 2002 Overall, ceftriaxone and aztreonam were the best substrates for the detection of the ESBL phenotype between both E. coli isolates and K. pneumoniae ESBL phenotypes; however, there was significant variation between countries in substrate preference. Aztreonam 25-34 EsbL Escherichia coli 85-89 11929691-8 2002 Overall, ceftriaxone and aztreonam were the best substrates for the detection of the ESBL phenotype between both E. coli isolates and K. pneumoniae ESBL phenotypes; however, there was significant variation between countries in substrate preference. Aztreonam 25-34 EsbL Escherichia coli 148-152 11442343-2 2001 Of the 668 isolates, the 80 strains were presumptively defined as ESBL producers according to the result of disk method using ESBL marker antibiotics (aztreonam, ceftazidime, and cefoxitin). Aztreonam 151-160 EsbL Escherichia coli 66-70 11794541-3 2001 Analysis of this strain by the double disk diffusion test showed synergies between amoxicillin-clavulanate (AMX-CA) and cefotaxime, and AMX-CA and aztreonam, which suggested that this strain produced a extended-spectrum beta-lactamase (ESBL). Aztreonam 147-156 CTX-M-15 Klebsiella pneumoniae 202-234 9705395-0 1998 Can results obtained with commercially available MicroScan microdilution panels serve as an indicator of beta-lactamase production among escherichia coli and Klebsiella isolates with hidden resistance to expanded-spectrum cephalosporins and aztreonam? Aztreonam 241-250 beta-lactamase Escherichia coli 105-119 11320450-2 2001 The highest percentage of ESBL phenotype (defined as a minimum inhibitory concentration [MIC] > or =2 microg/mL for ceftazidime, ceftriaxone, or aztreonam) was detected among K. pneumoniae strains from Latin America (45%), followed by those from the Western Pacific region (25%), Europe (23%), the United States (8%), and Canada (5%). Aztreonam 148-157 CTX-M-15 Klebsiella pneumoniae 26-30 11257029-8 2001 The gene, bla(KPC-1), was cloned in E. coli and shown to confer resistance to imipenem, meropenem, extended-spectrum cephalosporins, and aztreonam. Aztreonam 137-146 beta-lactamase Escherichia coli 10-13 11036023-1 2000 Serratia marcescens Rio-5, one of 18 extended-spectrum beta-lactamase (ESBL)-producing strains isolated in several hospitals in Rio de Janeiro (Brazil) in 1996 and 1997, exhibited a high level of resistance to aztreonam (MIC, 512 microgram/ml) and a distinctly higher level of resistance to cefotaxime (MIC, 64 microgram/ml) than to ceftazidime (MIC, 8 microgram/ml). Aztreonam 210-219 BES-1 Serratia marcescens 37-69 11036023-1 2000 Serratia marcescens Rio-5, one of 18 extended-spectrum beta-lactamase (ESBL)-producing strains isolated in several hospitals in Rio de Janeiro (Brazil) in 1996 and 1997, exhibited a high level of resistance to aztreonam (MIC, 512 microgram/ml) and a distinctly higher level of resistance to cefotaxime (MIC, 64 microgram/ml) than to ceftazidime (MIC, 8 microgram/ml). Aztreonam 210-219 BES-1 Serratia marcescens 71-75 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). Aztreonam 133-142 BES-1 Serratia marcescens 9-14 10705053-3 2000 Isolates with intermediate or resistant susceptibilities for extended spectrum cephalosporins or aztreonam were reported as probable ESBL producers. Aztreonam 97-106 EsbL Escherichia coli 133-137 10926441-3 2000 Different dosages of aztreonam injected into mice induced an increase in the lymphoproliferative response to specific mitogens and in the production of interleukin-2 by splenic cells, as well as a decreased response of this immune population to sheep erythrocytes lower total blood cell counts and a lower percentage of monocytes than in untreated mice. Aztreonam 21-30 interleukin 2 Mus musculus 152-165 9835525-9 1998 The addition of CAP18106-137 to aztreonam along with the bacteria did decrease the level of antibiotic-induced release of inflammatory mediators including tumor necrosis factor alpha, interleukin-6, and nitric oxide and also improved the survival of the mice. Aztreonam 32-41 tumor necrosis factor Mus musculus 155-182 9835525-9 1998 The addition of CAP18106-137 to aztreonam along with the bacteria did decrease the level of antibiotic-induced release of inflammatory mediators including tumor necrosis factor alpha, interleukin-6, and nitric oxide and also improved the survival of the mice. Aztreonam 32-41 interleukin 6 Mus musculus 184-197 9371336-4 1997 The purified enzyme was studied from a kinetic point of view, revealing the highest catalytic efficiency (k[cat]/Km) values for ceftazidime and aztreonam compared with the TEM-1 prototype enzyme. Aztreonam 144-153 TEM-1 Serratia marcescens 172-177 9687393-6 1998 Transformants producing only the pI 8.8 beta-lactamase were resistant to cefotaxime and aztreonam but were susceptible or intermediate to ceftazidime. Aztreonam 88-97 Bla Salmonella enterica subsp. enterica serovar Typhimurium 40-54 9529499-9 1998 Both continuous metronidazole and aztreonam reduced lung MPO concentration (P < 0.05) and TNF-alpha and IL-1 beta mRNA expression (P < 0.05) compared with those in saline controls. Aztreonam 34-43 myeloperoxidase Mus musculus 57-60 9529499-9 1998 Both continuous metronidazole and aztreonam reduced lung MPO concentration (P < 0.05) and TNF-alpha and IL-1 beta mRNA expression (P < 0.05) compared with those in saline controls. Aztreonam 34-43 tumor necrosis factor Mus musculus 93-102 9529499-9 1998 Both continuous metronidazole and aztreonam reduced lung MPO concentration (P < 0.05) and TNF-alpha and IL-1 beta mRNA expression (P < 0.05) compared with those in saline controls. Aztreonam 34-43 interleukin 1 beta Mus musculus 107-116 9593123-1 1998 A TEM-1 beta-lactamase derivative containing the single amino acid substitution A237T slightly increased (from 24 to 32 microg/ml) the cephalothin MIC for Escherichia coli RYC1000 but did not influence the activities of cefotaxime, ceftazidime, and aztreonam (MICs of 0.03, 0.12, and 0.06 microg/ml, respectively). Aztreonam 249-258 TEM-1 beta-lactamase Escherichia coli 2-22 1384868-9 1992 Furthermore, the MAb showed no inhibitory reaction with various beta-lactams except aztreonam- and ceftazidime-EACA conjugates in the ELISA inhibition test, suggesting that Az-3 recognize a new antigenic determinant (NAD), which is formed by the conjugation of beta-lactam and carrier protein. Aztreonam 84-93 ornithine decarboxylase antizyme 3 Homo sapiens 173-177 8851581-2 1996 Salmonella typhimurium JMC isolated in Argentina harbors a bla gene located on a plasmid (pMVP-5) which confers transferable resistance to oxyiminocephalosporins, aztreonam, and ceftibuten. Aztreonam 163-172 Bla Salmonella enterica subsp. enterica serovar Typhimurium 59-62 7694816-10 1993 Interestingly, simultaneous injection of Aztreonam with rG-CSF significantly enhanced the effect of rG-CSF on the PMN functions. Aztreonam 41-50 colony stimulating factor 3 Rattus norvegicus 100-106 1499375-3 1992 Aztreonam showed a high affinity to chromosomal-mediated cephalosporinase P99, its Ki for inhibition of P99 with cephaloridine as substrate was 0.0159 microns. Aztreonam 0-9 protein phosphatase 1 regulatory subunit 10 Homo sapiens 74-77 1499375-3 1992 Aztreonam showed a high affinity to chromosomal-mediated cephalosporinase P99, its Ki for inhibition of P99 with cephaloridine as substrate was 0.0159 microns. Aztreonam 0-9 protein phosphatase 1 regulatory subunit 10 Homo sapiens 104-107 9011117-0 1996 Effect of recombinant human granulocyte colony-stimulating factor on combination therapy with aztreonam and clindamycin for infections in neutropenic patients with hematologic diseases. Aztreonam 94-103 colony stimulating factor 3 Homo sapiens 28-65 9011117-1 1996 The present multicenter study was performed to evaluate the effect of recombinant human granulocyte-colony stimulating factor (rhG-CSF) on combination therapy using aztreonam (AZT) and clindamycin (CLDM) to treat severe infection in neutropenic patients with hematologic diseases. Aztreonam 165-174 colony stimulating factor 3 Homo sapiens 88-125 9011117-1 1996 The present multicenter study was performed to evaluate the effect of recombinant human granulocyte-colony stimulating factor (rhG-CSF) on combination therapy using aztreonam (AZT) and clindamycin (CLDM) to treat severe infection in neutropenic patients with hematologic diseases. Aztreonam 176-179 colony stimulating factor 3 Homo sapiens 88-125 7695296-8 1995 Interestingly, the change from Gln to Lys at position 39 found in TEM-2, classically considered a neutral change, slightly but consistently increased the MIC of ceftazidime and aztreonam. Aztreonam 177-186 RASD family member 2 Homo sapiens 66-71 8071678-3 1994 Aztreonam induces dose-dependent phagocytosis up to 25 micrograms/ml concentrations; with a phagocytosis index (PIa) of 1.18 +/- 0.2 at 1 microgram/ml; of 1.27 +/- 0.2 at 10 micrograms/ml; of 1.42 +/- 0.3 at 25 micrograms/ml. Aztreonam 0-9 RPTOR independent companion of MTOR complex 2 Homo sapiens 112-115 8486571-5 1993 However, after incubation for 24 h, a significant rise in TNF production was noticed in the cefuroxime and aztreonam-treated cultures (6440 and 5969 ng/L, respectively) compared to the ceftazidime and imipenem-treated cultures (846 and 381 ng/L, respectively). Aztreonam 107-116 tumor necrosis factor Homo sapiens 58-61 8486571-10 1993 The differences in TNF production between these antibiotics could be explained by the production of filaments following treatment with cefuroxime, aztreonam and low-dose ceftazidime, resulting in late bacterial lysis with high levels of endotoxin, whereas treatment with imipenem or high-dose ceftazidime resulted in the formation of spheroplasts, resulting in early lysis of the bacteria and much lower levels of endotoxin. Aztreonam 147-156 tumor necrosis factor Homo sapiens 19-22 8486571-11 1993 The addition of taurolidine to either imipenem or aztreonam-treated cultures prevented a rise in TNF production as a result of nearly complete neutralization of the released endotoxin. Aztreonam 50-59 tumor necrosis factor Homo sapiens 97-100 1590704-5 1992 Aztreonam therapy lead to opposite results because the beta-lactamase activity decreased and aztreonam was able to mask beta-lactamase activity by acting as an inhibitor. Aztreonam 0-9 Beta lactamase Pseudomonas aeruginosa 55-69 1590704-5 1992 Aztreonam therapy lead to opposite results because the beta-lactamase activity decreased and aztreonam was able to mask beta-lactamase activity by acting as an inhibitor.
