Patients at risk for urinary tract infections. No interventions.
Point-of-care identification of pathogens and determination of antibiotic susceptibility will significantly improve the clinical management of UTI. We have previously developed a biochip based on microfabrication technology capable of rapid detection of pathogens. The specific objectives of the current proposal are: 1) Determination of microbial constituents in spinal cord injury (SCI) patients and development of additional species-specific probes against these pathogens; 2) Development of a rapid antibiotic susceptibility and molecular pyuria assay using the electrochemical biochip; and 3) Clinical validation of the biochip as a diagnostic test for UTI.
