The objective of this study was to evaluate the human health impact of using fluoroquinolones to treat bovine respiratory disease (BRD) in dairy heifers less than 20 months of age. Specifically, this study quantified the probability of persistent symptoms in humans treated with a fluoroquinolone, for a fluoroquinolone-resistant Campylobacter, Salmonella, or multidrug-resistant (MDR) Salmonella ...
Fluoroquinolones are relatively safe, effective antibiotics. As their use becomes more frequent, so will the adverse side effects. I highlight a rare but debilitating adverse reaction-fluoroquinolone-induced tendinopathy. Case reports and letters from 1987 to 1998 were identified by using Grateful Med and PubMed Internet accesses to the National Library of Medicine. Articles were reviewed for c...
OBJECTIVE To evaluate if oral fluoroquinolone use is associated with an increased risk of serious arrhythmia. DESIGN Bi-national cohort study, linking register data on filled prescriptions, cases of serious arrhythmia, and patient characteristics. SETTING Denmark, 1997-2011; Sweden, 2006-13. PARTICIPANTS The study cohort was derived from a source population of all Danish and Swedish adult...
Increasing numbers of fluoroquinolone-resistant Campylobacter coli isolates received at the Minnesota State Public Health Laboratory and at the Centers for Disease Control and Prevention have been a cause for concern. The gyrA quinolone resistance-determining regions of several fluoroquinolone-resistant isolates were sequenced to examine the mechanism of resistance. Ciprofloxacin-resistant C. c...
OBJECTIVE To study the predominant Neisseria gonorrhoeae strain types in Pakistan and to evaluate their correlation with fluoroquinolone resistance. METHOD A total of 314 strains were collected from 2007-2009. Of these 112 strains were randomly selected for serotyping via the coagglutination technique. Fluoroquinolone susceptibility was checked through the E-test method. Chi square was perfor...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
During a 9-year study period from 1997 through 2005, the association between antimicrobial resistance rates in Escherichia coli and outpatient antimicrobial consumption was investigated in 20 hospital districts in Finland. A total of 754,293 E. coli isolates, mainly from urine samples, were tested for antimicrobial resistance in 26 clinical microbiology laboratories. The following antimicrobial...
Resistance to antibiotics, especially clarithromycin, is the major cause of the failure to eradicate Helicobacter pylori. There are few studies in children concerning fluoroquinolone activity against H. pylori. Primary resistance to antibiotics including fluoroquinolones was studied in 55 H. pylori strains isolated from Japanese children. DNA sequences of the gyrA gene in fluoroquinolone-resist...
The interplay between bacterial antimicrobial susceptibility, phylogenetics and patient outcome is poorly understood. During a typhoid clinical treatment trial in Nepal, we observed several treatment failures and isolated highly fluoroquinolone-resistant Salmonella Typhi (S. Typhi). Seventy-eight S. Typhi isolates were genome sequenced and clinical observations, treatment failures and fever cle...
BACKGROUND We investigated the possible association between fluoroquinolone use and the rate of methicillin-resistant Staphylococcus aureus (MRSA) recovery from consecutive hospitalized patients. METHODS We conducted a nonrandomized, prospective, controlled interventional "fluoroquinolone-free" study at 4 large teaching hospitals in northwest France, catering to a total of 5,882,600 persons. ...
