FIG 1.

Mixed pathogens detection by CT and multi-PCR. (A) The positive rate of pathogens by CT was 78.0% (71/91). Bacteria were found in 63.7% (58/91) of the samples, including MP detected from 63.9% (55/86) of the samples. The targeted viruses were positive in 27.5% (25/91) of the samples. The co-positive rate of pathogens of bacteria and viruses was 13.2% (12/91). Twenty samples were negative tested by CT. (B) All (91/91, 100.0%) samples were positive tested by multi-PCR. The positive rate of MP and targeted viruses were 96.7% (88/91) and 87.9% (85/91), respectively. The co-positive rate of bacteria and viruses was 90.1% (82/91).
