AI Article Synopsis

  • Enrofloxacin (ENR) is a widely used synthetic antibiotic in veterinary medicine that helps treat animal diseases and enhance livestock growth, but its overuse can harm the environment and human health due to residual contamination.
  • Researchers have created a novel sensor using gold nanoparticles and aptamers (AuNPs-Apt) to specifically detect enrofloxacin residues, with impressive detection capabilities.
  • This biosensor demonstrates a broad detection range, high accuracy, quick results, low toxicity, and cost-effectiveness, making it a promising tool for monitoring enrofloxacin in various applications.

Article Abstract

Enrofloxacin (ENR), as a synthetic broad-spectrum antibiotic is widely utilized in veterinary medicine to treat animal diseases and promote livestock growth, it can inhibit bacterial DNA gyrase subunit A, thereby preventing bacterial DNA replication and exerting its antibacterial effect. However, excessive use of enrofloxacin poses significant risks to ecological balance and human health due to residual contamination. We have developed a novel ENR aptamer sensor based on the gold nanoparticles/aptamer (AuNPs-Apt) complexes, in which AuNPs were synthesized via the seed method and functionalized with aptamers. The optical properties, particle size, functional groups and morphology of the AuNPs-Apt probe were characterized by transmission electron microscope, Fourier transform infrared spectrometer and UV-vis spectrophotometer, respectively. The aptamer biosensor can specifically identify enrofloxacin, with a wide detection range (0.05-100g ml) and a good linear relationship (R2=0.99) within the detection range. In addition, the biosensor also has the advantages of short detection time, low biological toxicity, good stability, and low detection cost. Therefore, it shows a great prospect for practical application in the field of detecting enrofloxacin residues.

Avian pathogenic Escherichia coli (APEC) is a significant pathogen infecting poultry that is responsible for high mortality, morbidity and severe economic losses to the poultry industry globally, posing a substantial risk to the health of poultry. APEC encounters reactive oxygen species (ROS) during the infection process and thus has evolved antioxidant defense mechanisms to protect against oxidative damage. The imbalance of ROS production and antioxidant defenses is known as oxidative stress, which results in oxidative damage to proteins, lipids and DNA, and even bacterial cell death.

Background: Amplicon sequencing of kingdom-specific tags such as 16S rRNA gene for bacteria and internal transcribed spacer (ITS) region for fungi are widely used for investigating microbial communities. So far most human studies have focused on bacteria while studies on host-associated fungi in health and disease have only recently started to accumulate. To enable cost-effective parallel analysis of bacterial and fungal communities in human and environmental samples, we developed a method where 16S rRNA gene and ITS1 amplicons were pooled together for a single Illumina MiSeq or HiSeq run and analysed after primer-based segregation.
