Procedure for the Screening of Eggs and Egg Products to Detect Oxolonic Acid, Ciprofloxacin, Enrofloxacin, and Sarafloxacin Using Micellar Liquid Chr…
2019
A method based on micellar liquid chromatography was developed to determine oxolinic acid, ciprofloxacin, enrofloxacin, and sarafloxacin in eggs and egg products. The antimicrobial drugs were obtained in a micellar solution which was directly injected. The analytes were resolved using a C18 column and a mobile phase of 0.05 M sodium dodecyl sulfate—7.5% 1-propanol—0.5% triethylamine, buffered at pH 3 with phosphate salt, running under the isocratic mode. The signal was monitored by fluorescence. Validation was successfully performed according to the EU Commission Decision 2002/657/EC in terms of specificity, calibration range (LOQ to 1 mg/kg), linearity (R2 >
Plasmid-mediated QnrS2 determinant from a clinical Aeromonas veronii isolate.
2008
The main objective of this study was to determine the prevalence of the Qnr determinants in clinical and environmental Aeromonas spp. A total of 52 Aeromonas sp. isolates identified by biochemical methods (5), 25 isolated from natural waters (1) and 27 isolated from clinical samples from hospitals in Valencia, Spain, were tested for quinolone resistance by the disk diffusion method (4) (nalidixic acid, 30 μg; oxolinic acid, 2 μg; flumequine, 30 μg; ciprofloxacin, 5 μg; and levofloxacin, 5 μg). Among the studied isolates, 27 showed resistance to nalidixic acid and susceptibility to ciprofloxacin, 24 isolates were susceptible to both nalidixic acid and ciprofloxacin, and only 1, the A. veroni…
Occurrence of Drug-Resistant Bacteria in Two European Eel Farms
2005
ABSTRACT The occurrence of strains that are resistant to oxolinic acid, oxytetracycline, sulfamethoxazole-trimethoprim, and nitrofurantoin among heterotrophic bacteria, including human and fish pathogens, in two freshwater eel farms was investigated. High levels of individual- and multiple-drug-resistant bacteria were detected, although sampling events were not correlated with clinical outbreaks and drug therapy.
