Metagenomic diagnosis of severe psittacosis using multiple sequencing platforms.

ABSTRACT:

Background

Chlamydia psittaci is an avian pathogen that can cause lethal human infections. Diagnosis of C. psittaci pneumonia is often delayed due to nonspecific clinical presentations and limited laboratory diagnostic techniques.

Results

The MinION platform established the diagnosis in the shortest time, while BGISEQ-500 generated additional in-depth sequence data that included the rapid characterization of antibiotic susceptibility. Cytopathy appeared only in cell cultures of BALF. BALF yielded a higher bacterial load than sputum or blood, and may be the most suitable clinical specimen for the genomic diagnosis of severe pneumonia.

Conclusions

This study indicated that the benefits of metagenomic sequencing include rapid etiologic diagnosis of unknown infections and
