What are the methods for isolating and identifying bacterial pathogens?

Answer from top 1 papers

The isolation and identification of potential bacterial pathogens are critical processes in various fields, including clinical diagnostics, food safety, and environmental monitoring. The methodologies for these processes vary, ranging from traditional culture-based techniques to advanced molecular and spectroscopic methods.
Interestingly, while some studies have successfully isolated and identified bacterial pathogens using conventional culture methods (), others have employed novel techniques such as Multi-molecular infrared (MM-IR) spectroscopy ((Zhang et al., 2022)), droplet-based microfluidics (), and Raman spectroscopy (). These advanced methods have demonstrated high accuracy and rapid detection capabilities. For instance, the MM-IR system achieved a 100% recognition rate for different mixed types of bacteria ((Zhang et al., 2022)), and the integration of machine learning with surfaced enhanced Raman spectroscopy (SERS) showed high prediction accuracy for bacterial identification (). Moreover, droplet-based microfluidics combined with syringe filter-enabled strategies significantly accelerated pathogen identification and antimicrobial susceptibility testing ().
In summary, while traditional culture-based methods remain widely used for the isolation and identification of bacterial pathogens ( and ), there is a clear trend towards the adoption of rapid, sensitive, and specific techniques such as MM-IR spectroscopy ((Zhang et al., 2022)), droplet-based microfluidics (), and Raman spectroscopy with machine learning (). These advanced methods offer the potential to overcome the limitations of conventional approaches and provide faster and more accurate results for the detection of bacterial pathogens ((Zhang et al., 2022) and ).
