Revealing co-infections in pneumonia: A case report on advancing diagnosis with metagenomic sequencing technologies

Pneumonia, a frequent and serious complication in kidney transplant recipients, is significantly increased by long-term immunosuppressive medication. This case report details a patient with lung cavitation, in which conventional microbiological methods revealed Escherichia coli as the principal pathogen. Metagenomic long-read sequencing also identified Klebsiella pneumoniae as a co-pathogen, underscoring the shortcomings of traditional diagnostic techniques. In identifying infectious pathogens, this case illustrates the superior diagnostic accuracy of long-read sequencing, offering crucial information that conventional methods might miss. The implementation of sophisticated sequencing technologies may overcome these diagnostic deficiencies, improving infection care in challenging and immunocompromised patients.
