The factor responsible for experimental keratoconjunctivitis (EKC) can be successfully preserved in enteroinvasive Escherichia coli (EIEC) strains for decades. In this respect an adequate freeze-drying technique is essential, whereas the question of protective media appears to be of less importance. The preservation of EKC-producing factor may be associated with the maintenance of some other related properties.
