• To evaluate the potential of microarray technology for broad-spectrum pathogen detection.

Main Methods:

• Development of a diagnostic microarray platform for viral pathogen identification.
• Utilized Phi29 polymerase for random amplification of viral material from diverse clinical samples.
• Employed the Microbial Detection Array for subsequent identification of amplified viral pathogens.

Main Results:

• Successfully generated sufficient viral material for identification using the Microbial Detection Array.
• The method demonstrated broad-spectrum detection capabilities for various viral pathogens.
• The assay could detect both DNA and RNA viruses simultaneously and differentiate subtypes.

Conclusions:

• The established diagnostic microarray platform shows significant potential for broad-spectrum viral pathogen detection.
• This method offers a comprehensive approach for identifying multiple viruses, including DNA and RNA types, in a single sample.
• The proposed assay is suitable for routine diagnostic analysis of viral infections in clinical settings.
