Estimation of outer membrane permeability of carbapenem antibiotics to Pseudomonas aeruginosa.

Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy

Iyobe S, Watanabe M, Mitsuhashi S, Inoue M.
PMID: 11810510
J Infect Chemother. 1999 Sep;5(3):168-170. doi: 10.1007/s101560050028.

The outer membrane permeability of carbapenems (imipenem [IPM], panipenem [PAPM], meropenem [MEPM], and biapenem [BIPM]) and ceftazidime (CAZ) to Pseudomonas aeruginosa was determined by the Zimmermann and Rosselet method. The permeability coefficients of beta-lactams tested at 50 &mgr;M concentration...

Retrospective analysis of antibiotic susceptibility patterns of respiratory isolates of Pseudomonas aeruginosa in a Turkish University Hospital.

Annals of clinical microbiology and antimicrobials

Gonlugur U, Bakici MZ, Ozdemir L, Akkurt I, Icagasioglu S, Gultekin F.
PMID: 12665428
Ann Clin Microbiol Antimicrob. 2003 Mar 07;2:5. doi: 10.1186/1476-0711-2-5.

BACKGROUND: Lower respiratory tract infections due to Pseudomonas aeruginosa have a high mortality rate. Antibacterial activity of various antibiotics against P. aeruginosa isolated from each hospital depends on the variety or amount of antibiotics used in each hospital.METHOD: A...

Piperacillin/Tazobactam: Evaluation of Its In vitro Activity against Bacteria Isolated in Two Brazilian Hospitals and an Overview of Its Antibacterial Activity, Pharmacokinetic Properties and Therapeutic Potential.

The Brazilian journal of infectious diseases : an official publication of the Brazilian Society of Infectious Diseases

We investigated the effects of the antibiotic ceftazidime (CAZ) on the cytolytic action of the neutrophil myeloperoxidase-hydrogen peroxide-chloride anion system (MPO/H(2)O(2)/Cl(-)). In this system, myeloperoxidase catalyses the conversion of H(2)O(2) and CI(-) to the cytotoxic agent HOCl. Stimulated neutrophils...
