title: Development of a lymphocyte transformation assay for rotavirus in whole blood and breast milk.
abstract: A multivariate assay was developed for detecting lymphoproliferative responses to rotavirus in whole blood and breast milk. Detection of lymphocyte transformation in samples from healthy uninfected adults required an assay incorporating a large number of antigen and cell concentrations and several incubation periods before pulsing. In contrast, lymphoproliferation to rotavirus was observed over a wider range of these variables in blood collected from a kidney recipient nine days post-rotavirus infection. Lymphoproliferation to rotavirus was detected in 32.5% of breast milk samples tested. The magnitude of lymphoproliferation to rotavirus did not correlate with rotavirus-specific IgG ELISA antibody titres in sera or with rotavirus-specific IgA ELISA antibody titres in breast milk.
