Patient-specific pathogenic bacteria

Patient-specific pathogenic bacteria represent the unique bacterial isolates recovered from an individual patient during an infectious process. These pathogens are the primary targets for precision medicine interventions, such as tailored antibiotic regimens and personalized bacteriophage therapy (Schooley et al., 2017, Antimicrob Agents Chemother). Unlike broad-spectrum approaches, targeting patient-specific isolates accounts for the unique phenotypic and genotypic characteristics of the strain, including its specific antimicrobial resistance (AMR) profile (NIH, 2023). The biological function of these targets involves host colonization, nutrient acquisition, and the evasion of the host immune system through various virulence factors. In clinical settings, the identification of these bacteria is achieved through diagnostic techniques like culture-based sensitivity testing or whole-genome sequencing (WGS) to guide therapeutic decisions (StatPearls, 2023). Effective targeting of these bacteria is essential for treating recalcitrant infections, particularly those caused by multi-drug resistant (MDR) organisms, while attempting to preserve the patient's commensal microbiota.
