In these cases the localizations were done by a beta-elimination reaction in mild alkaline solution after periodate oxidation. We report now on a method generally applicable on carbohydrates. The localization of phosphate groups and the extent of substitution with phosphate residues in carbohydrates can be determined by the following reaction sequence: methylation, dephosphorylation, and reetherification (labelling) with C2H3J or C2H5J followed by derivatizing to partially methylated alditol acetates and analysis by combined gas liquid chromatography/mass spectrometry. The results presented here are obtained by application of this method to isolated core oligosaccharides of lipopolysaccharides from E. coli C23.1, E. coli C71, E. coli F2515, and P. mirabilis R4/O 28. Phosphate is localized at C-4 of the chain heptoses in the lipopolysaccharides of E. coli C and E. coli R4, and at C-7 of the branching heptose in the lipopolysaccharide of P. mirabilis R4/O 28.</p>","PeriodicalId":23929,"journal":{"name":"Zentralblatt fur Bakteriologie. 1.

The M+ variant of streptococci, characterized by the presence of filamentous protrusions on the cell wall, displayed a high capacity for adherence, in contrast to the M- variant of the same strain, where adherence was low. The first stage of the interaction between M+ variant of Group A streptococci and HEp-2 cells was adherence of the filamentous protrusions of the bacterial cell wall to host cell cytoplasmic membrane; this was followed by closer contact of the streptococcus cell wall with HEp-2 cell surface. Continuing incubation led to the development of invaginations in the cytoplasmic membranes of HEp-2 cells, into which streptococci gradually penetrated. Ingestion of streptococci into the forming pseudovacuoles of the host cell was accompanied by bacterial cell division, culminating in total disintegration of the host cell and release of the streptococci into the medium. At all stages of the interaction there was a pronounced tendency to form multiple contacts between the surface structures of the streptococcus cell and the membrane structures of the animal cell being attacked.</p>","PeriodicalId":23929,"journal":{"name":"Zentralblatt fur Bakteriologie. 1.

The unstable variants differed antigenically from the parent in the agglutinin-absorption test; however, the agglutinin-absorption test was found to be inadequate for showing the antigenic difference between the parent and the unstable variants because their difference was diminished when the agglutinin-absorbed antigen was increased. The application of Laurell rocket immunoelectrophoresis (LRI) to the SDS-extracted antigens revealed the distinct difference between the parent and the unstable variants. Other findings presented herein indicated the difference between the antigens of the parent and the unstable variants to be one of quantity.
