Slow Release of Nitric Oxide from Charged Catheters and Its Effect on Biofilm Formation by Escherichia coliAntimicrobial Agents and Chemotherapy - Tập 54 Số 1 - Trang 273-279 - 2010
G. Regev-Shoshani, Mary Ko, Christopher Miller, Yossef Av‐Gay
ABSTRACT
Catheter-associated urinary tract infection is the most prevalent cause of nosocomial infections. Bacteria associated with biofilm formation play a key role in the morbidity and pathogenesis of these infections. Nitric oxide (NO) is a naturally produced free radical with proven bactericidal effect. In this study, Foley urinary cathet...... hiện toàn bộ

ABSTRACT
Colistin, administered as its inactive prodrug colistin methanesulfonate (CMS), is often used in multidrug-resistant Gram-negative pulmonary infections. The CMS and colistin pharmacokinetics in plasma and epithelial lining fluid (ELF) following intravenous and pulmonary dosing have not been evaluated in a large-animal model with pulmonary archite...... hiện toàn bộ
Evidence for the generation of active oxygen by isoniazid treatment of extracts of Mycobacterium tuberculosis H37RaAntimicrobial Agents and Chemotherapy - Tập 27 Số 3 - Trang 404-407 - 1985
H. A. Shoeb, B. U. Bowman, Abramo C. Ottolenghi, Aristide Merola
Crude extracts of Mycobacterium tuberculosis H37Ra, an isonicotinic acid hydrazide (isoniazid) (INH)-susceptible strain which has peroxidase activity, catalyzed the production of catechol from phenol in the presence of INH and H2O2 as shown by the development of the 444-nm absorption peak of oxidized catechol product. Extracts of the INH-resistant strain of M. tuberculosis H37Ra, which has...... hiện toàn bộ
Scanning Electron Microscopy of the H37Ra Strain of Mycobacterium tuberculosis Exposed to IsoniazidAntimicrobial Agents and Chemotherapy - Tập 4 Số 1 - Trang 62-65 - 1973

The morphology of cells of the H37Ra strain of
Mycobacterium tuberculosis
exposed to 0.5 μg of isonicotinic acid hydrazide (isoniazid) per ml was examined by scanning electron microscopy (SEM). Cells that were exposed to isoniazid for 3 h showed no detectable change, whereas cells exposed to the drug for 24 h exhibited diverse...... hiện toàn bộ
Enzymatic and nonenzymatic superoxide-generating reactions of isoniazidAntimicrobial Agents and Chemotherapy - Tập 27 Số 3 - Trang 408-412 - 1985

During the course of horseradish peroxidase-mediated oxidation of either o-dianisidine or 2-2'-azino-di(3-ethyl-benzthiazoline-6-sulfonic acid) (ABTS), no O2 consumption took place. When isonicotinic acid hydrazide (isoniazid) (INH) was included in the reaction mixture, O2 was consumed in amounts linearly related to the INH concentration. Nicotinic acid hydrazide at equimolar concentration...... hiện toàn bộ
