Identification of Pathogenic Bacteria of Diabetes Foot Ulcer

Condition(s) studied

Investigational drug(s) / intervention(s)

The infected wound of the patient's foot ulcer was collected: The infected wound of the patient's foot ulcer was collected

Study summary

The objective of this study is to design and develop a gene chip for detecting pathogenic bacteria in diabetic foot infection wounds. This innovative gene chip technology enables rapid and accurate identification of pathogens at the site of infection by detecting the 16SrDNA sequence of pathogenic bacteria.

Diabetic foot infection is a common serious complication in diabetic patients, often accompanied by complex pathogenic bacteria population, and due to the variety of infection types, traditional pathogen detection methods are time-consuming and low accuracy, patients may miss the best treatment opportunity. Now commonly used genetic identification of pathogenic bacteria often find a variety of bacteria, resulting in the actual pathogenic bacteria difficult to judge.

Eligibility
