In vitro detection of porcine rotavirus-like virus (group B rotavirus) and its antibody.

Abstract Four isolates of porcine rotavirus-like virus (PRVLV) infected MA104 cells and induced syncytium formation after low-speed centrifugation of the inoculum onto the monolayer. Ten of 44 (23%) Ohio swine sera had PRVLV antibodies when tested by indirect immunofluorescence, using PRVLV-infected MA104 cell monolayers as antigen.
