Biosensing platforms for Vibrio bacteria detection based on whole cell and nucleic acid analysis: A review

Abstract

Vibrio related illnesses are increasing worldwide in humans and marine animals. The detection of these bacteria is still mainly performed using traditional microbiological methods based on culture grown on differential agar media which are labor intensive, time consuming and unsuitable for in-field and high-throughput analysis. To overcome these limitations, biosensing platforms have emerged as promising alternative tools for rapid, sensitive, and real-time detection of Vibrio species in clinical, food and environmental samples. In this review, we will focus on strip test devices, and on optical and electrochemical biosensors developed for Vibrio analysis. Particular attention is given to sample preparation techniques.
