Abstract Background Bacterial translocation is considered the pathophysiological hallmark in development of spontaneous bacterial peritonitis (SBP). Prokinetics can increase gastrointestinal (GIT) motility, reduce small bowel transit time, decrease translocation, and possibility SBP. The aim this work was to compare effectiveness safety itopride norfloxacin versus only secondary prophylaxis for...

Eighty patients undergoing routine standardised extracapsular cataract surgery with lens implantation were divided randomly into two groups in a prospective double blind study comparing effects of preoperative norfloxacin eyedrops with placebo on bacterial contamination of anterior chamber aspirates after surgery. Pathogenic organisms were identified from 19 (24%) of the aspirates. The most com...

Sixty clinical isolates of M. tuberculosis, 24 susceptible and 36 resistant to conventional primary antituberculous drugs, were tested against four fluoroquinolones (ciprofloxacin, ofloxacin, pefloxacin and norfloxacin). Ofloxacin and ciprofloxacin were found to be the most active, with minimum inhibitory concentration (MIC) of 0.6 mg/l or less to all strains tested. Strains resistant to isonia...

Fluoroquinolones are broad-spectrum antibiotics that target gyrase and topoisomerase IV, involved in DNA compaction segregation. We synthesized 28 novel norfloxacin hydroxamic acid derivatives with additional metal-chelating hydrophobic pharmacophores,...

Agricultural practices such as wastewater irrigation and manure application may contaminate soils with antibiotics and, consequently, lead to human health risk. The co-application of three waste-derived materials, sewage sludge (SL), Chinese medicinal herbal residues (CMHR) biochar (BC), a soil amendment was proposed recently for minimizing the antibiotic amount in crop tissues. fate six antibi...

The efficacy of pivmecillinam for empirical treatment of acute uncomplicated urinary tract infection (UTI) was initially reported in clinical trials published in the 1970s and 1980s. Bacteriological cure rates observed in these trials were consistently >85%, and studies of different dosing regimens suggested that a 3 day course was appropriate. Comparative studies reported that pivmecillinam wa...

Whereas fluoroquinolone resistance mainly results from target modifications in gram-positive bacteria, it is primarily due to active efflux in Listeria monocytogenes. The aim of this study was to dissect a novel molecular mechanism of fluoroquinolone resistance in this important human pathogen. Isogenic L. monocytogenes clinical isolates BM4715 and BM4716, respectively susceptible and resistant...
