    Abstract With the rapid emergence and dissemination of antimicrobial resistance (AMR) genes in bacteria from animal, animal-derived food and human clinic, it is of great significance to develop new approaches to combat the multidrug-resistant bacteria. This study presented a short linear antimicrobial peptide RW-BP100-4D, which was derived from RW-BP100 (RRLFRRILRWL-NH2) by transforming the N-terminal 4th amino acid from L- to D-enantiomer. This modification remarkably reduced the peptide cytotoxicity to mammalian cells, as indicated by hemolytic and cytotoxicity assays. Meanwhile, the antimicrobial activity of RW-BP100-4D was improved against a more variety of Gram-positive and Gram-negative bacteria (sensitive and resistant) as well as fungi. Also, RW-BP100-4D showed strong

    Abstract This study presented an effective and sensitive SERS substrate for rapid detection of thiabendazole (TBZ) in fruit samples. A core–shell gold/silver nanorod (Au@Ag NRs) has been synthesized as a bimetallic SERS-active substrate. The obtained substrate showed an excellent SERS effect because of the tunable plasmon resonance of Au NRs, the significantly enhanced effect of silver, and the bimetallic synergistic effect of Au@Ag NRs. Under optimal conditions, the substrate was used to detect TBZ in fresh apple juice and peach juice with limits of detection of 0.032 and 0.034 ppm respectively. In addition, the recovery rate was within a satisfactory range of 95–101%, indicating that the Au@Ag NRs substrate could be a SERS detection platform for fruit pesticides residues with great development potential.

    Abstract This study focused on the occurrence of seventeen veterinary antibiotics and six resistant bacterias in soils from the vegetable farms fertilized with animal manure in China. Seventeen veterinary antibiotics, including sulfonamides, quinolones, tetracyclines, macrolides and amphenicols, were detected by high performance liquid chromatography/tandem mass spectrometer in all the 53 soil samples collected in four provinces during August 2016. The concentrations of target antibiotics in the soil samples ranged from not detectable to 415.00 μg/kg dry weight with the mean residual levels of the five classes followed order: tetracyclines (82.75 μg/kg) > quinolones (12.78 μg/kg) > macrolides (12.24 μg/kg) > sulfonamides (2.61 μg/kg) > amphenicols (0.06 μg/kg). Moreover, the highest antibiotic levels were found mainly in soil from organic vegetable farms. Risk assessment by using the methods of risk quotient, suggested that oxytetracycline, chlortetracycline, enrofloxacin and ciprofloxacin could pose severe ecological risk in sampled soils. Resistant strains were isolated in 30 samples, with Escherichia coli and Klebsiella pneumonia found the dominant bacterial hosts with resistance genes. Antibiotic resistance genes, including tetA, tetB, qnrS, oqxA, sul1, sul2, ermA and floR, were detected in the strains resistant to: tetracyclines, quinolones, sulfonamides, macrolides and amphenicols resistance, respectively. Overall, there was a correlation between the results of antibiotic risk assessment with the detection of resistance genes from isolated strains in the soils.

    Abstract Matrix certified reference materials (CRMs) are an indispensable part of method validation and have played an important role in ensuring reliable analytical results. To retain similarity to real samples, a new matrix CRM for the mass fraction of ciprofloxacin in whole liquid egg was developed by use of incurred materials with a target value corresponding to residue levels in real sample. The source materials were collected from laying hens following oral administration of ciprofloxacin. An optimized homogenization method and a strict bottling process were applied to bulk whole egg materials to prepare the CRM candidate. The mass fraction of ciprofloxacin in whole liquid egg was certified by a collaborative characterization program with eight accredited participating laboratories. Liquid chromatography coupled with isotope dilution mass spectrometry was studied as a reliable reference method for value assignment and was used by all participating laboratories. The certified value and expanded uncertainty (k = 2, at a confidence level of 95%) was 39.7 ± 5.2 μg/kg for ciprofloxacin in whole liquid egg. Homogeneity, long-term stability at -70 °C for 12 months, and short-term stability at -18 °C, 4 °C, and room temperature were assessed for 9 days. Additionally, uncertainties arising from inhomogeneity, instability, and characterization were analyzed in detail and fully estimated. This CRM would be a useful tool for validation of analytical methods and proficiency testing in ciprofloxacin residue analysis of egg. Graphical Abstract
