Whenever there is a diarrhoea problem in pigs between 10 and 40 days of age rotavirus infection either as primary agents or secondary must be considered. Electron microscopy and ELISA tests in the laboratory are required for confirmation. Try the litmus test by soaking scour in litmus paper, E. coli infections turn blue, virus infections red.
