Mobilome and antibiotic resistance in Acinetobacter baumannii
… world. Third-generation cephalosporins (such as ceftazidime) and carbapenems (such as imipenem and meropenem) represent important treatment options for infections caused by this microorganism. Nevertheless, the number of strains resistant to these antibiotics has been increasing during the last …

Antimicrobial Nanoparticles: A Green and Novel Approach for Enhancing Bactericidal Efficacy of Commercial Antibiotics
… capping ability of a cephalosporin antibiotic, ceftazidime. No signs of aggregation or leaching of ceftazidime from GNP surface was observed upon its storage. Antibacterial testing showed dosedependent broad spectrum activity of Cef-GNPs against both Gram-positive (S. bovis and E. durans) and …

Collateral sensitivity and the evolution of drug resistance in Escherichia coli
… reduce the frequency of mutation to resistance. Ceftazidime resistant strains showed susceptibility to chloramphenicol. It was therefore expected that growth in sub-MIC concentrations of chloramphenicol would reduce mutation rate to ceftazidime resistance, however, an increase in mutation rate …

Rapid methods for bacterial identification and predicting antibiotic resistance by MALDI-TOF MS
… Burkholderia pseudomallei identification and ceftazidime resistance determination. B. pseudomallei ceftazidime susceptible and resistant ΔpurM mutant strains Bp82 and Bp82.3 were infected with broadly targeting B. pseudomallei phage ϕX216 and production of the m/z 37.6 kDa phage capsid protein …

Creation and validation of an enhanced in vitro model of the lungs
… from those obtained in the regular NGI.|Ceftazidime was chosen as the antibiotic of choice because of its broad spectrum of activity and potential use in the treatment of pneumonia. Escherechia coli K12 MG 1655 was chosen for the bacterial studies because of its susceptibility to …

Antimicrobial susceptibility of Acinetobacter isolates from Groote Schuur Hospital region : an investigation of the appropriateness/validity of the NCCLS zone size criteria
… species, especially for cefepime (CPIM) and ceftazidime (CT AZ). Since Acinetobacter species contribute significantly to the increased morbidity and mortality of debilitated patients ( especially v entilated ICU patients, and the fact that clinicians rely on the antimicrobial susceptibility …

Beyond MICS: Determining the Role of Porin Production and β-Lactamase Expression in Resistance and Cellular Physiology of Klebsiella pneumoniae
… evaluated by rt RT PCR. MICs to cefotaxime, ceftazidime, cefepime, ceftolozane/tazobactam, ceftazidime/avibactam, meropenem, meropenem-vaborbactam, and imipenem-relebactam were determined by E-test using CLSI guidelines. β-lactamase clones were generated by restriction digest cloning. …

Persistence of Culturable Antibiotic Resistant Fecal Coliforms From Manure Amended Vegetable Fields
… agars supplemented with different antibiotics (ceftazidime, clindamycin, erythromycin, sulfamethoxazole, and tetracycline). Given the number of samples with resistant fecal coliform concentrations below the limit of detection, analyses to identify the effects of soil treatment and crop relied on …

Studies on the mode of action and beta-lactamase inhibitory properties of novel oxapenem compounds
… activity. Combination of the oxapenems with ceftazidime afforded protection against ß-lactamase-producing strains, including hyperproducers of class C enzymes and extended-spectrum ß-lactamase enzymes. A fixed 4µg/ml concentration of AM-112 protected a panel of eight cephalosporins against …

Lysin Based Antimicrobial Peptides Against Acinetobacter Baumannii
… exhibited MICs comparable to levofloxacin and ceftazidime and acted synergistically with polymyxin B. While the peptides were shown to kill by disrupting the bacterial cytoplasmic membrane, they did not lyse human red blood cells or B cells; however, serum was found to be inhibitory to lytic …

A study of clinical strains of Pseudomonas Aeruginosa and the investigation of antibiotic resistance mechanisms in the multidrug resistant strain PA13
… and tetracycline. All were sensitive to ceftazidime, piperacillin-tazobactam, cefepime, ceftriaxone, meropenem, aztreonam, amikacin, apramycin, butirosin A, lividomycin and colistin sulphate. One of the isolates, PA13, was resistant to a further fourteen antibiotics and was identified as …

In vitro activity of cephalosporins against selected gram negative bacilli : [a thesis]
… Cefuroxime, Cedonicid; third generation: Ceftazidime, Ceftizoxime, Cefotaxime, Cefoperazone, Ceftriaxone, Moxalactam) were studied against 146 strains of Gram negative bacilli belonging to the following families: Enterobacteriaceae Proteus vulgarius (2), P. mirabilis (5), Providencia …

The microbiology of diabetic foot infections: a Ghanaian perspective
… could resist and/or tolerate antibiotics such as ceftazidime and levofloxacin up to 1280 times their minimum inhibitory concentration. K. pneumoniae and P. mirabilis were also found to express the interspecies AI–2 quorum sensing molecules which significantly increased biofilm formation and fold …
