A Cohort Study on the Pathogen Spectrum of Liver Transplant Recipients Complicated With Infection
The goal of this observational study is to map the pathogen profile of secondary infections in liver transplant recipients, to correlate the basic immune status with the characteristics of the secondary infection pathogen profile, and to establish an early warning system for monitoring secondary infections, so as to explore safe and effective therapeutic modalities to further reduce the morbidity and mortality of liver failure. The main questions it aims to answer are:

Characterize the distribution of pathogenic bacteria infecting liver transplant recipients.
Establish a monitoring and early warning system for secondary infections.
