| Popis: | An assay is described for handling clinical specimens for the detection of cytomegalovirus. It consists of low-speed centrifugation of the specimen on human embryonic lung cells, using a technique adapted from chlamydial culture, followed by detection using a monoclonal antibody against the cytomegalovirus early antigen in an immunofluorescence technique. This assay was compared with the conventional cell culture system. 161 specimens obtained from 52 patients were studied; from 14 patients CMV was isolated in at least one specimen (in total 28 specimens). The centrifugation technique led to positive results generally within 24 to 48 h, whereas the cell culture took an average of 16.5 days to develop the typical cytopathic changes. No cross-reactions between the cytomegalovirus monoclonal antibody and other viruses present (herpes simplex virus and adenovirus) were observed. The centrifugation technique is a reproducible and rapid method in the diagnosis of cytomegalovirus infection. |
