Little information about immunity to respiratory syncytial virus (RSV) and disease pathogenesis in elderly persons exists. Humoral immunity to RSV was assessed in 41 young, 56 healthy elderly, and 49 frail elderly adults by measuring baseline RSV specific IgG by enzyme immunoassay (EIA) and microneu

Abstract
The relationship between serum immunoglobulins and the severity and risk of Respiratory Syncytial Virus (RSV) infection in the institutionalized elderly was prospectively assessed during the winter of 1989β1990 at a 591 bed nursing home. Forty RSV infections were identified out of 149 respiratory illnesses by isolation of the virus or by a β₯fold rise in RSVβspecific IgG by EIA. Acute serum RSV IgG levels were similar in those with RSV infection and those with nonβRSV illness. Additionally, among the RSVβinβfected elderly there was no correlation between severity of clinical symptoms and level of acute IgG titers by EIA or virus neutralization. The results of this study suggest that humoral immunity does not play a major role in reducing the risk of infection nor modulating the clinical severity of illness in elderly persons with RSV infections.

The humoral immune response to Respiratory Syncytial Virus (RSV) was investigated in old and young adults. RSV was identified by culture and/ or reverse transcription polymerase chain reaction (RT-PCR) in 52 elderly (mean age 74 years) and 15 young adults (mean age 33 years) with respiratory illness
## Abstract Differences in the severity of respiratory syncytial virus (RSV)βinduced lower respiratory disease in infants have been attributed to multiple environmental and genetic factors. To identify the genetic factor(s) influencing RSV susceptibility, we examined RSV infection in eight inbred m
During the course of 26 respiratory syncytial (RS) virus infections, infected cells in the respiratory tract become coated with immunoglobulins (IgA, IgG, and IgM), IgA being predominant. Methods are described for detecting both intracellular virus and coating immunoglobulin using a double staining
The immunological response of infants younger than six months to infection with respiratory syncytial virus (RSV) was studied in relation to clinical severity. IL-6 and IL-8 were found more frequently and at higher levels in the plasma samples of more severely ill patients and no significant differe
