Identification of a new transposon Tn5403 in a Klebsiella pneumoniae strain isolated from a polluted aquatic environment.

AKlebsiella pneumoniae strain having mobilization “helper” potential has been isolated from the river Rhine. Analysis of the transconjugants resulting from the mobilization of nonconjugative pBR-type plasmids and RSF1010 derivatives showed that the transfer-helper capacity of theK. pneumoniae strain is related to the presence of a Tn3-like transposable element, Tn5403. This element has been identified and localized in a plasmid.

L'analyse des données multidimensionnelles par le langage d'interrogation des données (LID) Au delà de l'analyse des correspondances

Multidimensional data analysis with LID data Interrogation language. Chapter I describes the three stages which lead to the analysis of a questionnaire by the language LID: correspondence analysis, data structuring, data exploration with LID. Chapter II describes the language LID and the interface program INTERF between EyeLID-I and ADDAD. Chapter III presents two concrete examples of application: the first is the reanalysis of a British survey; the second is the analysis of a French survey. Chapter IV, in the framework of a ternary frequency table, presents a study of data interaction.
