Cell-mediated cytotoxic response to respiratory syncytial virus in infants with bronchiolitis.
A cell-mediated cytotoxic response to respiratory syncytial (RSV) was demonstrated in the peripheral blood of 4 of 22 infants with acute bronchiolitis. These 4 infants were aged 3 weeks to 3 months. No such response was found in infants older than 4 months. All 4 infants with a positive response had mild infections.
