A novel simultaneous detection system for human viruses was developed using a real-time polymerase chain reaction (PCR) system to identify causes of infection in clinical samples from patients with uncertain diagnoses.
This system, designated as the "multivirus real-time PCR," has the potential to detect 163 human viruses (47 DNA viruses and 116 RNA viruses) in a 96-well plate simultaneously.
The specificity and sensitivity of each probe-primer set were confirmed with cells or tissues infected with specific viruses.
The multivirus real-time PCR system:
• Showed profiles of virus infection in 20 autopsies of acquired immunodeficiency syndrome patients,
• And detected frequently TT virus, cytomegalovirus, human herpesvirus 6, and Epstein-Barr virus in various organs;
• However, RNA viruses were detected rarely except for human immunodeficiency virus-1.
Pathology samples from 40 patients with uncertain diagnoses were examined, including cases of encephalitis, hepatitis, and myocarditis.
• Herpes simplex virus 1, human herpesvirus 6, and parechovirus 3 were identified as causes of diseases in four cases of encephalitis,
• While no viruses were identified in other cases as causing disease.
This multivirus real-time PCR system can be useful for detecting virus in specimens from patients with uncertain diagnoses.
