^aNewborn piglets received an oral challenge with 3 × 10^3.5 TCID₅₀ of PEDV in PBS or PBS only and daily administration 60 mg of the MYCI mixture suspended in milk replacer or the vehicle for 7 days. Presence of the PEDV in feces was determined by reverse transcription-polymerase chain reaction. Data represent the number of PEDV-positive animals per total animals
