title: [Effect of the formation of spheroplasts and the subsequent reversions on the virulence and other biological traits of E. coli 0124:K72(B17)].
abstract: The authors present experimental data indicating that revertants with a manifest mucous capsule formed in the spheroplasts of E. coli O124 : K72 culture. The appearance of the latter depended on the presence of glucose, lactose, maltose, or glycerine in the medium. Mucous culture could be regarded as a prolonged modification induced with penicillin. Mucous substance aided preservation or partial restoration of the virulent properties by the given bacteria.
