For this purpose, Sarafloxacin (SAR) was employed to synthesize the immunogen and coating antigen through EDC conjugation method, and cell fusion technology was used to produce anti-SAR monoclonal antiobdy. Based on the square matrix titration, an icELISA method was established. The dynamic range for Sarafloxacin in assay buffer was from 0.004 to 18 ng/mL, with LOD and IC50 value of 0.002 ng/mL and 0.32 ng/mL, respectively. After optimization, the physiological pH (7.4) was selected for the immunoassays, and this assay could tolerate up to 10% acetonitrile. The results of this assay showed a high cross- reactivity to Difloxacin (85.5%), Norfloxacin (61.7%), and Pefloxacin (34.8%). Under the 10-fold dilution in authentic fish samples, the regression curve equations for Sarafloxacin, Difloxacin, Norfloxacin and Pefloxacin were y = 1.0114x - 0.4003, R2= 0.9901; y = 0.9782x + 0.2754, R2= 0.9807; y = 0.9892x +0.0489, R2= 0.9843; and y = 0.9797x +0.8017, R2= 0.9844, respectively. -

Twenty-one drugs of two different classes including seven tetracyclines and four types of quinolones (quinoline, naphthyridine, pyridopyrimidine and cino- line) were determined simultaneously in a single run. The homogenized sample tissues were extracted with EDTA–McIlvaine buffer solution and further purified using a polymer-based Oasis TM HLB solid-phase extraction (SPE) cartridge. An ACQUITY UPLC BEH C18 column was used to separate the analytes followed by tandem mass spectrometry using an electrospray ionization source. MS data acquisition was performed in the positive ion multiple reaction monitoring mode, selecting two ion transitions for each target compound. Recovery studies were performed at different fortification levels. -

Reproduction is authorised provided the source is acknowledged. Introduction On 6 February 2019, the European Commission sent a request to the European Medicines Agency (EMA) for a report on the criteria for the designation of antimicrobials to be reserved for the treatment of certain infections in humans in order to preserve the efficacy of those antimicrobials. The Agency was requested to provide a report by 31 October 2019 containing recommendations to the Commission as to which criteria should be used to determine those antimicrobials to be reserved for treatment of certain infections in humans (this is also referred to as ‘criteria for designating antimicrobials for human use’, ‘restricting antimicrobials to human use’, or ‘reserved for human use only’). The Committee for Medicinal Products for Veterinary Use (CVMP) formed an expert group to prepare the scientific report. The group was composed of seven experts selected from the European network of experts, on the basis of recommendations from the national competent authorities, one expert nominated from European Food Safety Authority (EFSA), one expert nominated by European Centre for Disease Prevention and Control (ECDC), one expert with expertise on human infectious diseases, and two Agency staff members with expertise on development of antimicrobial resistance . -

Simultaneous Determination of the Residues of Fourteen Quinolones
Vol. 30, 2012, No. 1: 74–82 Czech J. Food Sci. Simultaneous Determination of the Residues of Fourteen Quinolones and Fluoroquinolones in Fish Samples using Liquid Chromatography with Photometric and Fluorescence Detection Florentina CAÑADA-CAÑADA, Anunciacion ESPINOSA-MAnsILLA, Ana JIMÉneZ GIRÓN and Arsenio MUÑOZ DE LA PeÑA Department of Analytical Chemistry, University of Extremadura, Badajoz, Spain Abstract Cañada-Cañada F., Espinosa-Mansilla A., Jiménez Girón A., Muñoz de la Peña A. (2012): Simul- taneous determination of the residues of fourteen quinolones and fluoroquinolones in fish samples using liquid chromatography with photometric and fluorescence detection. Czech J. Food Sci., 30: 74–82. A chromatographic method is described for assaying fourteen quinolones and fluoroquinolones (pipemidic acid, marbofloxacin, norfloxacin, ciprofloxacin, danofloxacin, lomefloxacin, enrofloxacin, sarafloxacin, difloxacin, oxolinic acid, nalidixic acid, flumequine, and pyromidic acid) in fish samples. The samples were extracted with m-phosphoric acid/acetonitrile mixture (75:25, v/v), purified, and preconcentrated on ENV + Isolute cartridges. The determina- tion was achieved by liquid chromatography using C18 analytical column. A mobile phase composed of mixtures of methanol-acetonitrile-10mM citrate buffer at pH 4.5, delivered under optimum gradient program, at a flow rate of 1.5 ml/min, allows accomplishing the chromatographic separation in 26 minutes. For the detection were used serial UV-visible diode-array at 280 nm and 254 nm and fluorescence detection at excitation wavelength/emission wavelength: 280/450, 280/495, and 280/405 nm. The detection and quantification limits were between 0.2–9.5 and 0.7–32 µg/kg, respectively. The procedure was applied to the analysis of spiked salmon samples at two different concentration levels (50 µg/k and 100 µg/kg). -

Toxicity and residues of oxolinic acid. Thai J Hlth Resch 12(2): 125 - 139. Oxolinic acid is a quinolone derivative. It is a synthetic antimicrobial agent which used to treat bacterial urinary tract infections, especially gram negative bacteria. It has been used in veterinary medicine for the control of furunculosis, vibriosis and enteric redmouth diseases. The mechanism of action of oxolinic acid inhibited bacterial DNA synthesis by effecting on bacterial DNA gyrase. Toxicity of oxolinic acid occured mainly to the central nervous system and gastrointestinal tract. Most of studies of residues of oxolinic acid were found in aquaculture animals such as fish and shrimp because oxolinic acid is used worldwide in aquaculture industry. The studies found that the absorption of oxolinic acid in rainbow trout depended on the temperature of water. And the residue time of oxytetracycline in sediment was longer than oxolinic acid. In addition, oxolinic acid in hepatopancreas of shrimp had more higher concentration than haemolymph and muscle and it also persisted in hepatopancreas longer than muscle.

Accord- ingly, such infections are predominantly treated with broad-spectrum fluoroquinolo- http://aac.asm.org/ nes, such as moxifloxacin. Yet, the rising fluoroquinolone resistance has necessitated the development of alternative therapeutic options. Herein, we describe the devel- opment of a polymyxin B-trimethoprim (PT) ophthalmic formulation containing the antibiotic rifampin, which exhibits synergistic antimicrobial activity toward a panel of contemporary ocular clinical S. aureus and P. aeruginosa isolates, low spontaneous resistance frequency, and in vitro bactericidal kinetics and antibiofilm activities equaling or exceeding the antimicrobial properties of moxifloxacin.

One of the key approaches to tackling an- timicrobial resistance is clinical, livestock, and environmental surveillance applying methods capable of effectively identifying antimicrobial non-susceptibility as well as genes that promote resistance. Current clinical laboratory practices involve conventional culture-based antibiotic susceptibility testing (AST) methods, taking over 24 h to find out which medication should be prescribed to treat the infection. Although there are techniques that provide rapid resistance detection, it is necessary to have new tools that are easy to operate, are robust, sensitive, specific, and inexpensive. Chemical sensors and biosensors are devices that could have the necessary characteristics for the rapid diag- Citation: Reynoso, E.C.; Laschi, S.; nosis of resistant microorganisms and could provide crucial information on the choice of antibiotic Palchetti, I.; Torres, E. -

Hung1,2,3* New antibiotics are needed to combat rising levels of resistance, with new Mycobacterium tuberculosis (Mtb) drugs having the highest priority. However, conventional whole-cell and biochemical antibiotic screens have failed. Here we develop a strategy termed PROSPECT (primary screening of strains to prioritize expanded chemistry and targets), in which we screen compounds against pools of strains depleted of essential bacterial targets. We engineered strains that target 474 essential Mtb genes and screened pools of 100–150 strains against activity-enriched and unbiased compound libraries, probing more than 8.5 million chemical–genetic interactions. Primary screens identified over tenfold more hits than screening wild-type Mtb alone, with chemical–genetic interactions providing immediate, direct target insights.
