    The study enrolled 20 patients with psittacosis pneumonia, categorizing them based on the presence of respiratory failure at admission.

  • 2

    Patients with respiratory failure showed a significant increase in C. psittaci sequences compared to those without respiratory failure.

  • 3

    A significant negative correlation was found between C. psittaci sequences and CD4+ T-lymphocyte counts, indicating potential immune response impairment.

  • 4

    A negative correlation between C. psittaci and Pseudomonas suggests a competitive relationship, while Veillonella showed a positive correlation with C. psittaci.

  • 5

    The findings provide preliminary insights into the relationship between lung microbiota composition and the severity of psittacosis pneumonia.
