A Primary Division of the Genus Shigella Based on the Trimethylamine Test.
As pointed out by Neter (1942) S. ailkalescens is not infrequently mistaken for S. paradysenteriae. To a lesser extent a similar condition holds true for S. sonnei cultures fermenting lactose much more slowly than the average strain. Diagnostic laboratories without adequate antiserums could use either the Eijkman or the trimethylamine test or both to good advantage with ShigeUa cultures. Consid...
متن کاملBiochemical investigation of Providence strains and their relationship to the Proteus group.
The search for the possible causative agents of acute infective diarrhoea in infants and children has brought to light a great number of groups and strains of enteric bacteria other than Salmonella and Shigella. None of them can yet be incriminated with certainty as being pathogenic. The problem of potential or conditioned pathogenicity cannot be solved without a more comprehensive knowledge of...
متن کاملThe Cultural and Antigenic Properties of Shigella sonnei.
The present study aims to define the taxonomic position of that group of dysentery bacteria commonly known as Shigella paradysenteriae, var. sonnei (Bergey, 1934). Most of the material on which this work is based has been recently isolated in this laboratory but a number of type strains of the species from The National Collection of Type Cultures in London, England, have been included for compa...
متن کاملOn the Nature of the Toxic Component of the Somatic Antigen of Shigella Paradysenteriae Type Z (flexner)
From the chemical evidence presented it appears that the toxicity associated with the somatic antigen of Type Z Sh. paradysenteriae may be attributed to an entity distinct from the known components of the complex. That this substance is neither the protein, the lipid, nor the carbohydrate component of the antigen is evident. Because of its lability to chemical manipulation, the nature of the to...
متن کاملHydrogen Sulfide Formation by Shigella alkalescens.
The Shigella are generally regarded as organisms that fail to form hydrogen sulfide. In a recent report on a lead semisolid agar, Friewer and Shaughnessy (Am. J. Clin. Path., 8, 1) observed the formation of H2S by several strains of Shigella paradysenteriae (Flexner) and Shigelka sonnei in this medium and also by the lead acetate paper test, although no mention was made of this reaction by Shig...
