Electrosyneresis (ES) method was successfully applied to the detection of the specific antigen on infectious flacherie virus of the silkworm (IFV-specific antigen) with the following results.Precipitated line was formed by ES when the IFV-specific antigen was placed on the cathode side and anti-IFV serum was placed on the anode side. The ES method was far better than the micro-Ouchterlony method in the sensitivity, and the precipitated line was observed at 32-fold dillution of IFV-specific antigen. The IFV-specific antigen was detected from the midgut of silkworms which had been administered with heavy and light inocula of the IFV. This was found 4-5 days earlier than the appearance of the symptom. The ES method is practically applicable to the rapid diagnosis of infectious flacherie of the silkworm.
