Detection of bacteriophages in environmental samples is a critical step in understanding their role in ecosystems and their potential applications in biotechnology and medicine. This process involves isolating and identifying phages from diverse sources like soil, water, and wastewater. Advanced techniques such as PCR, sequencing, and plaque assays are used to detect and characterize these viruses accurately. Detection of bacteriophages in environmental samples helps researchers study their diversity, host interactions, and potential for phage therapy, environmental monitoring, and biocontrol applications.
