title: [Detection of the host specificity system in shigellae].
abstract: The presence of DNA host specific system in Shigella sonnei 47843 bacteria has been demonstrated. Phage DDIII grown on the cells of Shigella stutzeri 2, in Shigella sonnei 47843 cells is restricted by a factor of 105. Phage T3 of Eco B phenotype as well as DDIII phage is restricted in these cells. This circumstance means that the restriction-modification system of Shigella sonnei 47843 differs in specificity from the well known system E. coli. The results obtained are the second case of host specific system identification in Shigella. The biological properties of the strain (form of the colonies, colicinogenic activity, antibiotic resistance, ability to ferment sugars, etc.) have been studied.
