Rotavirus-specific neutralization assay enables evaluation of mucosal immune responses.

ABSTRACT: Mucosal infections are a major global health concern in humans and animals. Neutralization assays are considered the gold standard for evaluating functional antibodies but are typically limited to serum analysis. This often excludes mucosal sample types such as saliva or intestinal mucus, which may better reflect local immunity, particularly for enteric pathogens such as Rotaviruses (RV). We optimized and standardized a virus neutralization assay (VNA) for RVA to evaluate its applicability across serum, intestinal mucus, and saliva samples. Five key protocol variables were systematically assessed: (i) the applied trypsin concentration, (ii) the incubation time for proteolytic activation of the RV, (iii) the infection dose applied, (iv) the duration of neutralization time and (v) sample-spe
