Rapid diagnosis of invasive cytomegalovirus infection by examination of tissue specimens in centrifugation culture.
Two hundred eight tissue specimens from 81 patients were examined by centrifugation culture for the rapid diagnosis of invasive cytomegalovirus (CMV) infection. Results were compared with those obtained by both conventional viral cultures and histologic examination. CMV was identified by centrifugation culture in 52 (25%) specimens at 16 hours after inoculation, including 39 lung specimens and 12 gastrointestinal specimens. One additional esophageal specimen was positive (53 of 208 specimens; 25.5%) at 36 hours. In contrast, CMV was recovered from only 50 of these 53 specimens by conventional cell culture at a mean of 11 days after inoculation. Forty-three of the 208 specimens (20.5%) were positive for CMV when examined by histologic methods, including light microscopy and tissue immunofluorescence. All 43 were positive by centrifugation culture. Specimens that were positive by centrifugation culture but negative by histologic methods included three lung specimens and seven gastrointestinal specimens. The technic of centrifugation culture is more sensitive for diagnosis of invasive CMV infection by the examination of affected tissue than either conventional viral culture or histologic technics, including tissue immunofluorescence, and more rapid than conventional culture or routine histologic examination.
