Diphtheria-phage inhibitor produced by treating the host bacterium with oleic acid.
In work previously carried out in this laboratory it was shown that the nonionic surface active agent polyoxyethylene sorbitan monooleate (Tween 80) inhibited the adsorption of a Corynebacterium diphtheriae phage to its host cell (Groman and Bobb, 1955). During this investigation oleic acid, a known contaminant of Tween 80, was also tested for its ability to inhibit phage adsorption. In contras...
متن کاملRelation between adsorption of diphtheria phage and its inactivation by an oleic acid-activated inhibitor.
It was previously reported (Groman, 1961) that an inhibitor of phage B of Corynebacterium diphtheriae and related phages was produced when the host strain C4 was exposed to low concentrations of oleic acid. The evidence indicated that inhibition was biologically specific. In the present study a more detailed examination of the specificity of inhibition was undertaken, and the results suggest th...
متن کاملOleic Acid Produced by a Marine Vibrio spp. Acts as an Anti-Vibrio parahaemolyticus Agent
It is known that some strains of Vibrio parahaemolyticus are responsible for gastroenteric diseases caused by the ingestion of marine organisms contaminated with these bacterial strains. Organic products that show inhibitory activity on the growth of the pathogenic V. parahaemolyticus were extracted from a Vibrio native in the north of Chile. The inhibitory organic products were isolated by rev...
متن کاملPhage Conversion and the Role of Bacteriophage and Host Functions in Regulation of Diphtheria Toxin Production by Corynebacterium diphtheriae
Corynebacterium diphtheriae is the etiologic agent of diphtheria. Toxinogenic isolates of C. diphtheriae produce diphtheria toxin, a protein that inhibits protein synthesis in susceptible eukaryotic cells, whereas nontoxinogenic isolates of C. diphtheriae do not produce diphtheria toxin. The characteristic local and systemic manifestations of diphtheria are caused by diphtheria toxin. The toxin...
