Viable Ascaris sp. egg that has been treated with Domestos (a sodium hypochlorite and soap based South African household disinfectant), at a 50% dilution, with a 1 hour exposure time. Sodium hypochlorite is known to decorticate the egg upon exposure - The outer layers of the egg have been removed, appearing quite membranous -hence the loss of colour. Exposure to the disinfectant seemed to agitate the larva within, causing rapid movement.
