Inactivation of {beta}-lactamases from Enterobacter cloacae by monophosphams (1988)

Bush, Karen, Smith, S. A., Tanaka, S. K., Bonner, D. P.

Amongst the monocyclic β-lactam antibiotics, selected monophosphams were potent mechanism-based inactivators of the P99 and E2 cephalosporinases of Enterobacter cloacae. Inhibition of these enzymes...

Activities of Tobramycin and Six Other Antibiotics against Pseudomonas aeruginosa Isolates from Patients with Cystic Fibrosis

Shawar, Ribhi M., MacLeod, David L., Garber, Richard L., Burns, Jane L., Stapp, Jenny R., Clausen, Carla R., ...

The in vitro activity of tobramycin was compared with those of six other antimicrobial agents against 1,240 Pseudomonas aeruginosa isolates collected from 508 patients with cystic fibrosis during...

In vitro evaluation of ABT-719, a novel DNA gyrase inhibitor.

Flamm, R K, Vojtko, C, Chu, D T, Li, Q, Beyer, J, Hensey, D, ...

ABT-719 (A-86719.1) is the first compound of a new class of novel DNA gyrase inhibitors, the 2-pyridones, with potent antibacterial activity against gram-positive, gram-negative, and anaerobic...

Mutations in 23S rRNA are associated with clarithromycin resistance in Helicobacter pylori.

Versalovic, J, Shortridge, D, Kibler, K, Griffy, M V, Beyer, J, Flamm, R K, ...

Twelve clarithromycin-resistant Helicobacter pylori isolates (100% of resistant isolates examined) from seven different patients each contained an A-->G transition mutation within a conserved loop of...

A PCR-oligonucleotide ligation assay to determine the prevalence of 23S rRNA gene mutations in clarithromycin-resistant Helicobacter pylori.

Stone, G G, Shortridge, D, Versalovic, J, Beyer, J, Flamm, R K, Graham, D Y, ...

We have developed a rapid PCR-oligonucleotide ligation assay that can discriminate single base substitutions that are associated with clarithromycin resistance in Helicobacter pylori. Susceptible...

In vitro evaluation of tigemonam, a novel oral monobactam.

Tanaka, S K, Summerill, R A, Minassian, B F, Bush, K, Visnic, D A, Bonner, D P, ...

Tigemonam, a novel, orally administered monobactam, exhibited potent and specific activity in vitro against members of the family Enterobacteriaceae, Haemophilus influenzae, and Neisseria...

Improved sensitivity in assays for binding of novel beta-lactam antibiotics to penicillin-binding proteins of Escherichia coli.

Bush, K, Smith, S A, Ohringer, S, Tanaka, S K, Bonner, D P

Tigemonam and temocillin, but not aztreonam, bound to penicillin-binding proteins (PBPs) 1a and 3 of Escherichia coli with apparent improved affinity when challenged with benzylpenicillin at lowered...

Resistance caused by decreased penetration of beta-lactam antibiotics into Enterobacter cloacae.

Bush, K, Tanaka, S K, Bonner, D P, Sykes, R B

Strains of Enterobacter cloacae were selected on the basis of resistance to aztreonam, ceftazidime, moxalactam, or imipenem. All strains produced the same E2 beta-lactamase, with an isoelectric point...

In vitro and in vivo evaluations of A-80556, a new fluoroquinolone.

Clement, J J, Tanaka, S K, Alder, J, Vojtko, C, Beyer, J, Hensey, D, ...

A-80556 is a novel fluoroquinolone with potent antibacterial activity against gram-positive, gram-negative, and anaerobic organisms. A-80556 was more active than ciprofloxacin, ofloxacin,...

Molecular typing of Helicobacter pylori isolates from a multicenter U.S. clinical trial by ureC restriction fragment length polymorphism.

Shortridge, V D, Stone, G G, Flamm, R K, Beyer, J, Versalovic, J, Graham, D W, ...

The molecular typing of 81 pretreatment Helicobacter pylori isolates and the comparison of 18 pretreatment-posttreatment pairs is described by restriction fragment length polymorphism (RFLP) of the...

Variability in susceptibilities of Haemophilus influenzae to clarithromycin and azithromycin due to medium pH.

Nilius, A M, Beyer, J M, Flamm, R K, Tanaka, S K

The National Committee for Clinical Laboratory Standards (NCCLS) methods for susceptibility testing of Haemophilus influenzae in Haemophilus test medium allow a pH range of 7.2 to 7.4. However, it is...
