How do you detect resistant strains?

Resistant strains of pathogens can be detected through various laboratory methods, including culture and sensitivity testing, where microorganisms are grown in the presence of antibiotics to observe growth patterns. Molecular techniques, such as PCR and whole-genome sequencing, can also identify specific resistance genes or mutations. Additionally, epidemiological surveillance and data analysis help monitor resistance trends in populations. These methods together provide a comprehensive approach to detecting and understanding resistant strains.
