Differentiation of cytomegalovirus antigens by their reactivity with various classes of human antibodies in the indirect fluorescent antibody test.

Abstract

Human sera containing immunoglobulin G (IgG), IgA, and IgM antibodies were tested by immunofluorescence for reactivity with cytomegalovirus-infected cell cultures and with early antigens of cytomegalovirus produced by treating the infected cultures with either bromodeoxyuridine or cytosine arabinoside. IgG antibody but not IgM antibody reacted with early antigens produced in bromodeoxyuridine-treated infected cultures. This observation on a small sample of sera suggested that a positive IgM reaction with an infected, nontreated culture and a negative reaction with a bromodeoxyuridine-treated infected culture may indicate a positive specific IgM reaction for cytomegalovirus, even in the presence of IgM rhematoid factor. The hyothesis requires further testing. The different classes of antibody did not all react or did not react to the same extent with early antigens produced in infected cells blocked with cytosine arabinoside or bromodeoxyuridine. This observation indicates that different antigens were being produced as a result of the two treatments.
