N S Churilova, and S A Goncharova, and Iu V Vul'fovich, and N D Konstantinova, and L N Kats

The comparative study of antigen localization in the initial streptococcus, in its stable L-forms and in the revertant obtained from the L-forms in early L-transformation passages. has been carried out. In this study 3 sera were used in homologous and heterologous reactions Ferritin-labeled homologous antibodies have been shown to localize directly on the cell-wall surface in the initial strain and in the capsule-like slime in the revertant. The L-forms have been found to possess some membrane-localized antigens in common with the revertant and, to a lesser extent, with the initial streptococcal strain.

D007740 L Forms Bacterial variants, unable to form a complete cell wall, which are formed in cultures by various bacteria; granules (L bodies) appear, unite, and grow into amorphous bodies which multiply and give rise to bacterial cells morphologically indistinguishable from the parent strain.
D005293 Ferritins Iron-containing proteins that are widely distributed in animals, plants, and microorganisms. Their major function is to store IRON in a nontoxic bioavailable form. Each ferritin molecule consists of ferric iron in a hollow protein shell (APOFERRITINS) made of 24 subunits of various sequences depending on the species and tissue types.
