Reversion of L forms and spheroplasts of Proteus mirabilis.
Altenbern, Robert A. (U.S. Army Chemical Corps, Fort Detrick, Frederick, Md.). Reversion of L forms and spheroplasts of Proteus mirabilis. J. Bacteriol. 85:269-272. 1963.-Spheroplasts or 3-B type L forms of Proteus mirabilis formed by growth in the presence of penicillin are able to revert to the bacillary form, as judged by regain of resistance to osmotic shock. Reversion takes place in the ab...
متن کاملReversion of 3A type L forms of Proteus mirabilis.
Reversion of L forms to the normal bacterial state has been described in general terms in a variety of bacterial cell-L-form systems (Dienes and Weinberger, 1951). The relatively large 3B type L colony formed on penicillin-containing medium is composed entirely of spherical bodies of varying sizes (2 to 10 ,u in diameter) that appear to propagate by a budding process. In contrast, 3A type L for...
متن کاملCritical factors influencing growth of L forms of Proteus mirabilis.
The observations, primarily by Dienes and associates, of L colonies arising spontaneously or by penicillin induction from species of Proteus or Salmonella led to the description of two morphologically distinct colonial forms, designated as the 3B type and the 3A type. It has been reported further that the viable elements of these two types exhibit markedly dissimilar properties such as size, nu...
متن کاملCell Wall and Cytoplasmic Membrane of Escherichia coli
Cell Wall and Cytoplasmic M e m b r a n e of Escherichia coli.* BY EDOUAm) K~LLE~mEROER arm Azcro~Ea'rE RYTER. The existence of two envelopes in bacteria has been postulated to account for numerous observations related to the presence of an osmotic barrier with differential permeability (1, 2), the occurrence of free, metabolizing protoplasts (3), and the possibility of producing plasmolysis (1...
متن کاملSynergism of polymyxin and sulfonamides in L-forms of Staphylococcus aureus and Proteus mirabilis.
Earlier workers suggested that synergism of polymyxin and sulfonamides occurred because sulfonamides produced changes in the cell wall which permitted the more ready access of polymyxin. We tested this hypothesis by using L-forms, which lack cell wall. The demonstration that synergism of polymyxin and sulfonamides occurs in L-forms of Proteus mirabilis and Staphylococcus aureus suggested that t...
