Respiratory Syncytial Viroses and Coronavimses	1973-11-17		.txt	text/plain	4090	299	50	RS virus was estimated, from sucrose density gradient centrifugation studies, to be 90-120 nm in diameter [2] ; viral particles in infected cells measured 65 nm by electron microscopy. All adults tested possessed detectable levels of neutralizing antibody to RS virus before challenge, but the titer of naturally acquired antibody had no significant effect on subsequent RS infection of volunteers and was poorly correlated with development of mild clinical illnesses. The neutralization test is more sensitive than CF when serum from infants is used, but rises in neutralizing antibody have been detected in only half of the virus-positive infections in this age group. Virus structures were detected 6-8 hr later [17] .· Infection of WI-38 cells with strain 229E resulted in a reorganization of the cytoplasm, as determined by electron microscopy.
