Animal experiment: | For the depletion studies, 240 1-day-old Cobb chicks are used. The chickens are housed in pens that contains 30 birds each (10 birds/m2) and are provided ad libitum access to water and non-medicated feed. The chickens are randomly allocated into four experimental groups, labeled from A to D, containing 80 birds each. Chickens in group A form the untreated control group, whereas those in group C are treated with 10 mg/kg bw of Sulfaquinoxaline sodium salt, which is administered via drinking water from the 32nd to 34th day of breeding[1]. |

Development of a novel carbon paste sensor for determination of micromolar amounts of Sulfaquinoxaline in pharmaceutical and biological samples
Mater Sci Eng C Mater Biol Appl 2016 Jan 1;58:504-9.PMID:26478338DOI:10.1016/j.msec.2015.08.034.
A potentiometric carbon paste sensor was fabricated for determination of Sulfaquinoxaline (SQX) based on the use of ion-association complex of Sulfaquinoxaline sodium with 2,3,5-triphenyltetrazolium chloride. The proposed sensor exhibited Nernstian slope of 58.4 ± 0.3 mV per decade for Sulfaquinoxaline over a wide concentration range of 5.0 × 10(-6) to 1.0 × 10(-2)M, with a low detection limit of 3.0 × 10(-6)M. The sensor manifested advantages of fast response time, satisfactory reproducibility, long life time, high thermal stability and, most importantly, excellent selectivities for Sulfaquinoxaline relative to a wide variety of common foreign inorganic cations, anions, sugars and amino acids. The sensor was successfully used for determination of Sulfaquinoxaline in pharmaceutical solution, blood serum, urine and milk samples. The isothermal coefficient of the electrode was calculated by the investigation of temperature effects on the electrode potential response.
Lasalocid: resistance and cross-resistance studies in Eimeria tenella-infected chicks
Poult Sci 1975 May;54(3):750-6.PMID:1153374DOI:10.3382/ps.0540750.
Eimeria tenella was passaged in the presence of suboptimal and optimal concentrations of lasalocid (X-537A, sodium salt) in feed. Lasalocid was equally active at concentrations of 0.006 and 0.0075% against the 10th and 15th passage of E. tenella lasalocid exposed strains. Resistance to lasalocid could not be induced. Lasalocid administered in the feed at 0.0075% was tested in controlled battery experiments against E. tenella strains resistant to known anticoccidials in chicks. These studies demonstrated that lasalocis, at the optimal feed concentration of 0.0075% was highly effective against coccidiosis induced by strains of E. tenella resistant to Sulfaquinoxaline, nicarbazine, zoalene, emprolium, clopidol and 4-hydroxyquinoline. Lasalocid medicated chicks were heavier, converted feed more efficiently, showed less pathologic lesions, and had lower mortality (P less than or equal to .05) than the infected unmedicated controls as well as Sulfaquinoxaline, nicarbazine, zoalene, amprolium-ethopabate, clopidol, buquinolate, decoquinate and nequinate medicated groups. Cross-resistance to lasalocid was not demonstrated.
Tolerance intervals modeling for design space of a salt assisted liquid-liquid microextraction of trimethoprim and six common sulfonamide antibiotics in environmental water samples
J Chromatogr A 2019 Feb 8;1586:18-29.PMID:30528769DOI:10.1016/j.chroma.2018.12.003.
Sulfonamides and trimethoprim combinations have been used extensively as antimicrobial agents for prevention and treatment of human and animal infections. Although many microextraction methods were developed for monitoring their residues in environmental water, none of these methods applied liquid-liquid microextraction for this purpose. This work presents for the first time a simultaneous Salt Assisted Liquid-Liquid Microextraction SALLME coupled with HPLC-UV for determination of trimethoprim and six common sulfonamide residues (sulfathiazole, sulfadiazine, sulfadmidine, sulfamethoxazole sulfadoxine and Sulfaquinoxaline) in water samples. Co-extraction of trimethoprim with sulfonamides was achieved by the addition of perchloric acid as a chaotropic agent to the extraction medium. Quality by Design framework was applied to develop and optimize both of SALLME and HPLC steps to ensure procedure robustness and sensitivity. Tolerance interval modeling of SALLME responses was applied to construct the design space of SALLME procedure. The optimized HPLC system enabled fast, sensitive and robust separation the extracted compounds within four minutes. The method detection limits of the method were in the range of 2.15-7.64 ng.mL-1. These values were far below the guidelines recommended limits (35 and 70 ng.mL-1 for each individual sulfonamide and trimethoprim respectively).
Dispersive liquid-liquid microextraction combined with ultra-high performance liquid chromatography for the simultaneous determination of 25 sulfonamide and quinolone antibiotics in water samples
J Pharm Biomed Anal 2013 Mar 5;75:130-7.PMID:23246932DOI:10.1016/j.jpba.2012.11.026.
In this work, a dispersive liquid-liquid microextraction (DLLME) procedure combined with ultra-high performance liquid chromatography with diode-array detection was developed to determine 25 antibiotics in mineral and run-off waters. Optimum DLLME conditions (5 mL of water at pH=7.6, 20% (w/v) NaCl, 685 μL of CHCl₃ as extractant solvent, and 1250 μL of ACN as disperser solvent) allowed the repeatable, accurate and selective determination of 11 sulfonamides (sulfanilamide, sulfacetamide, sulfadiazine, sulfathiazole, sulfadimidin, sulfamethoxypyridazine, sulfadoxine, sulfamethoxazole, sulfisoxazole, sulfadimethoxine and Sulfaquinoxaline) and 14 quinolones (pipemidic acid, marbofloxacin, fleroxacin, levofloxacin, pefloxacin, ciprofloxacin, lomefloxacin, danofloxacin, enrofloxacin, sarafloxacin, difloxacin, moxifloxacin, oxolinic acid and flumequine). The method was validated by means of the obtention of calibration curves of the whole method as well as a recovery study at two levels of concentration. The LODs of the method were in the range 0.35-10.5 μg/L with recoveries between 78% and 117%.
Development of a modified QUick, Easy, CHeap, Effective, Rugged and Safe method for the determination of multi-class antimicrobials in vegetables by liquid chromatography tandem mass spectrometry
J Chromatogr A 2014 Nov 14;1368:52-63.PMID:25311488DOI:10.1016/j.chroma.2014.09.074.
A modified quick, easy, cheap, efficient, rugged and safe (QuEChERS) method coupled with liquid chromatography tandem mass spectrometry (LC-MS/MS) was developed for rapid determination of 26 veterinary antimicrobials in vegetables. Samples were extracted by single-phase extraction with acetonitrile-methanol (85:15, v/v) and citric buffer solution, followed by liquid-liquid partitioning with the addition of anhydrous magnesium sulfate and sodium chloride. A dispersive solid-phase extraction with primary secondary amine was applied for cleanup. Concentration and solvent exchange was performed prior to LC-MS/MS analysis. All matrix-matched calibration curves were linear with correlation coefficients (r) over 0.99. Recoveries for all the analytes spiked at 0.5 (1 or 1.5), 5 and 50 ng/mL were in the range of 60.0-98.0%, except for Sulfaquinoxaline, sulfaclozine and doxycycline, with relative standard deviations below 25% for the low concentration level, 20% for the medium and 15% for the high. The decision limits and the detection capabilities of the analytes ranged from 0.005 to 0.5 μg/kg and from 0.02 to 1.5 μg/kg, respectively. The method was developed and validated in accordance with romaine lettuce matrix, and higher recovery rates were obtained from the other five kinds of vegetables including white radish, Chinese cabbage, cucumber, string bean and green pepper. Matrix effects of different vegetables were evaluated and signal suppression effect was observed for the majority of 26 analytes. Finally, the method was applied to the analysis of real samples collected from the agricultural areas in the vicinity of local pig farms, and the phenomenon of vegetables contaminated by antimicrobials residues is provoking.
