Generic identification of L-forms by polyacrylamide gel electrophoretic comparison of extracts from parent strains and their derived L-forms.
A polyacrylamide gel electrophoretic method was used for identification of L-forms in the genera Streptococcus, Staphylococcus, and Proteus, by comparing phenol-acetic acid-water extracts of homologous parent L-form pairs to one another and to other pairs. The method requires only milligram quantities of material for analysis. The standard patterns for the strains used in this study are shown a...
متن کاملL Extension of ∂̄-closed Forms from a Hypersurface
Let X be a Kähler manifold of complex dimension n with smooth Kähler metric ω, and Z ⊂ X a smooth complex hypersurface. Let L→ X be a holomorphic line bundle with a possibly singular Hermitian metric e−φ whose singular locus does not lie in Z, i.e., such that e|Z is a metric for L|Z . Assume also that the line bundle EZ → X associated to the divisor Z has a holomorphic section fZ such that Z = ...
متن کاملSerological reactions of glycolipids from streptococcal L-forms.
Parent bacteria and L-forms of some streptococci of group A, group D, and Streptococcus MG share common antigens as shown by cross-reactivity in growth inhibition, complement fixation, and Ouchterlony tests. Cross-reactivity between these streptococci or their L-forms with a staphylococcal L-form, or Mycoplasma pneumoniae, was found only rarely and only in low-titer complement fixation tests. R...
متن کاملPhagocytosis of microbial L-forms.
Little data are available regarding L-form phagocyte interactions. Due to difficulty with more conventional methods, a serum-free technique of surface phagocytosis employing cellulose ester micropore filters, fluorochrome staining, and reflecting fluorescence microscopy was developed. Intracellular localization of L-frms was confirmed by electron microscopy. In timed experiments, phagocytosis o...
متن کاملCellular Reactions to Polysaccharides from Tubercle Bacilli and from Pneumococci
1. Purified tuberculo-polysaccharides are relatively innocuous both to normal and to tuberculous guinea pigs. 2. Both tuberculo-polysaccharides and polysaccharides from pneumococci call larger numbers of leucocytes from the blood vessels than do saline and dextrose and trehalose. 3. The mechanisms controlling the delivery of lymphocytes and neutrophils into the blood stream are different. 4. Sl...
