| demonstration of the phenomena of microbial persistence and reversion with bacterial l-forms in human embryonic kidney cells. | a series of experiments was undertaken in which human embryonic kidney (hek) fibroblasts were infected with either relatively stable or stable l-forms of streptococcus faecalis. the infected cells were maintained by splitting over long periods (1 to 2 months) while samples were withdrawn for culture and electron microscopic studies. relatively stable s. faecalis l-forms could be cultured from infected cells only during the first week after infection, although l-form-like material was frequently ... | 1974 | 4214785 |
| proposed reproductive cycle for a relatively stable l-phase variant of streptococcus faecalis. | based on electron microscopic observations, the reproductive cycle of a relatively stable l-phase variant of streptococcus faecalis was proposed. the small, dense, nonvesiculated l-form is envisioned as the central (core) element. it was seen to divide and bud rapidly. in addition, the dense forms appeared to be capable of growth and development within vesicles of mature mother forms. when these forms were released from the vesicles into the surrounding fluid medium, further growth occurred, res ... | 1974 | 4214786 |
