Increased sensitivity for rapid detection of cytomegalovirus by shell vial centrifugation assay using mink lung cell cultures.

A comparative study was made of various human and non-human cell cultures to determine their sensitivity for cytomegalovirus (CMV) as detected by the production of CMV early antigen using the shell vial centrifugation assay. Mink lung cell cultures, frequently used for detection of herpes simplex virus in clinical specimens, were found to be significantly more sensitive to infection by CMV than other cell cultures tested. Using the shell vial centrifugation assay, the mink lung cell cultures were more sensitive than human diploid fibroblasts for the detection of the Davis strain of human CMV and CMV from clinical specimens.
