[Specific antibodies in children excreting cytomegalovirus]

Acute-and convalescent-phase sera from 22 children were examined by ELISA in comparison with a routine complement fixation (CF) test for detection of anti-CMV antibodies. All these subjects were excreting CMV from urine and/or saliva. The results showed that ELISA is more sensitive than CF test. Particularly ten children showed, by ELISA, anti-CMV antibody titers more agreeing with clinical-virological features. Generally, in other subjects the results of the two serological tests were similar. Three cases showed discordances both between the two methods and between serological data and clinical virological findings.
