The Recent Original Perspectives on Nonculture-Based Bacteria Detection Methods: A Comprehensive Review

Abstract

Foodborne diseases that are primarily caused by pathogenic bacteria are of major public health concern globally. One of the key strategies in minimizing and controlling the risk of contamination of food with such pathogens requires establishing effective detection and tracking methods of zoonotic bacteria. Although culture-based pathogen detection methods are developed and widely used by the industry traditionally, nonculture-based zoonotic bacteria detection methods are now more widely investigated and used owing to the recent developments in nucleic acid and immunological-based detection methods. These rapid detection methods provide the opportunity of acquiring real-time test results and high-throughput screening of a large number of samples at a time. One of the key aspects of rapid detection methods is the development of effective sample processing methods as food samples are heterogeneous and highly complex in composition. In this review, variety of sample processing methods, in terms of nonspecific and target-specific sample processing as well as thorough overview of recent developments in nonculture-based bacteria detection methods are presented.
