摘要: Representative electron micrographs, from the study of eight strains L forms and one strain Mycoplasma , are presented. A- B-type were derived two Proteus other a diphtheroid staphylococcus strain, (designated as LX) isolated group A β-hemolytic streptococcus staphylococcus. The was goats. Sections made young colonies grown within agar parts surface embedded in agar. produced by inoculation bacteria into media containing penicillin. large bodies developing organisms like parent bacteria, had cell wall consisting plasma membrane an outer wall. loss rigidity indicated alteration its structure. A-type cultures consisted irregular branching masses extending several directions, small dense corresponding to elementary corpuscles present intermediary forms. In contrast B-type, all surrounded single unit bacteria. structures inside membrane, both seemed correspond structure which contained ribosomes threads DNA. formed chains filaments, and, apparently, these took part multiplication gradual enlargement. seen studied, except corresponded size, shape, structure, well development corpuscles, form . spherical usually broth cultures, agar, similar morphology, discernible organisms, Significant morphological structural differences not apparent between (in media) under conditions this investigation.
