This study was designed to compare the killing effect of ciprofloxacin on strains of Klebsiella pneumoniae with different MICs of ciprofloxacin in vivo using the rat granuloma pouch infection model. Five different strains were used: one ciprofloxacin-susceptible strain (MIC 0.06 mg/L); one strain highly resistant to ciprofloxacin (MIC 8 mg/L); and three nalidixic acid-resistant strains with low...

The spread of antimicrobial resistance in environment is promoted at least in part by the inappropriate use of antibiotics in animals and humans. The present study was designed to investigate the impact of different concentrations of ciprofloxacin in soil containing manure on the development of plasmid-mediated quinolone resistance (PMQR) - encoding genes and the abundance of soil bacterial com...

BACKGROUND Previous studies have suggested that fluoroquinolone-resistant strains of Escherichia coli that infect humans probably emerged as a consequence of using fluoroquinolones in poultry. This study aims to provide further insight into the possible avian origin of fluoroquinolone-resistant extraintestinal pathogenic E. coli (ExPEC) strains that infect humans. METHODS We compared the phyl...

Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

purpose : to investigate the penetration of cefixime and ciprofloxacin to the rabbit eye on the basis of microbial inhibition of aqueous and vitreous humour after oral administration. methods : in this experimental study, 36 rabbits (72 eyes) were randomly divided into two groups group a consisted of 20 rabbits and group b 16 rabbits. each group was divided into four equal subgroups. the rabbit...

Between 2000 and 2006 the sum of ciprofloxacin and folic acid antagonists prescriptions to Bavarian (South-eastern Gemany) outpatients stayed constant. However, prescription numbers of ciprofloxacin increased while those of folic acid antagonists decreased suggesting an apparent shift in the treatment of urinary infections toward ciprofloxacin. During the observation period the proportion of E....

Ciprofloxacin is one of the most commonly used antibacterial agents with relatively few side effects. Serious adverse reactions reported with ciprofloxacin are rare with an incidence of 0.6%. Recently we came across two rare adverse effects of ciprofloxacin, viz. toxic epidermal necrolysis and agranulocytosis. To our knowledge, a total of seven cases have been reported in the literature documen...

Twenty-six hospitalized patients participated in a randomized crossover study to evaluate the effect of enteral feedings on ciprofloxacin absorption when given orally or via gastrostomy or jejunostomy tubes. Patients in the oral group received an intact 500-mg ciprofloxacin tablet alone or ciprofloxacin plus three oral doses of Sustacal (240 ml given 8 h before, with, and 4 h after ciprofloxaci...

Intestinal secretory movement of the fluoroquinolone antibiotic, ciprofloxacin, may limit its oral bioavailability. Active ATP-binding cassette (ABC) transporters such as breast cancer resistance protein (BCRP) have been implicated in ciprofloxacin transport. The aim of this study was to test the hypothesis that BCRP alone mediates intestinal ciprofloxacin secretion. The involvement of ABC tran...
