Prevalence of cytomegalovirus, human herpesvirus-6, and Epstein-Barr virus in periodontitis patients and healthy subjects in the Thai population.

Fifty periodontitis patients and 30 healthy patients with oral cavities were selected from the Faculty of Dentistry, Mahidol University, Bangkok, Thailand, from March 2001 to November 2002. Their ages varied between 15 and 70 years. Among the periodontitis patients, specimens were collected from both disease and healthy sites.

Rapid diagnosis of cytomegalovirus in Thai pediatric AIDS patients.

Blood samples were collected from 100 pediatric AIDS patients for the detection of CMV in pp65-bearing leukocytes (PBLs) by immunoperoxidase staining (IP) and PCR. IgM antibody assay was performed to determine the correlation of antigen and antibody. IP and PCR can be used as methods for the early detection of CMV (prior to the presence of IgM antibody).
