T-related bacteriophages isolated from Shigella sonnei.
نویسنده
چکیده
The properties of three T-related phages-35, 55, and 3201-isolated from Shigella sonnei were studied. They were similar with respect to morphology of plaques, duration of the latent periods, lysis inhibition effect, and serological characteristics. These phages closely resembled the T-even phages. Phages 3201, 35, and 55 had the same host range and receptor specificity as phage T2.

The Somatic Antigen of a Phage-resistant Variant of Phase Ii Shigella Sonnei
1. A phage-resistant variant of Phase II Shigella sonnei has been isolated and the type-specific antigen from it has been obtained. 2. The antigen of the variant microorganism, II/3, 4, 7, differs from that of the parent Phase II bacillus in serological specificity and in chemical make-up. 3. Although the antigen of Phase II Sh. sonnei inhibits all T phages to which the bacillus is susceptible,...
متن کاملBacteriophage typing of Shigella sonnei.
A bacteriophage-typing schema was developed for differentiating strains of Shigella sonnei. Sixty-seven bacteriophages were obtained from other collections, and 36 bacteriophages were isolated from sewage. From these 103 bacteriophages, a provisional set of 12 was chosen by computer analysis as being the most sensitive in differentiating strains of S. sonnei isolated in the United States. The p...
متن کاملThe Chemical and Antiviral Properties of the Somatic Antigen of Phase Ii Shigella Sonnei
1. The somatic antigen of Phase II Shigella sonnei can be isolated by extracting phenol-killed microorganisms with water. This substance inactivates all T phages to which this bacillus is susceptible. 2. The Phase II antigen is constituted from a protein and a phosphorylated lipocarbohydrate. The major portion of the protein component can be removed by digestion with pancreatin. The enzymatical...
متن کاملSpecific detection of Shigella sonnei by enzyme-linked aptamer sedimentation assay
Development of potent new anti-Shigella agents for rapid and specific detection and treatment is of great importance. Aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. In the present study, we used a Systematic Evolution of Ligands by Exponential enrichment (SELEX) process to select DNA aptamers that b...

Shigella strains are important agents of bacillary dysentery, and in recent years Shigella sonnei has emerged as the leading cause of shigellosis in industrialized and rapidly developing countries. More recently, several S. sonnei and Shigella flexneri strains producing Shiga toxin (Stx) have been reported from sporadic cases and from an outbreak in America. In the present study we aimed to she...
