title: The genetic basis of the aggregation system in Bacillus thuringiensis subsp. israelensis is located on the large conjugative plasmid pXO16.
abstract: The aggregation phenotypes Agr+ and Agr- of Bacillus thuringiensis subsp. israelensis are correlated with a conjugation-like plasmid transfer and characterized by the formation of aggregates when the bacteria are socialized during exponential growth. We present evidence for the association of the Agr+ phenotype with the presence of the large (135-MDa) self-transmissible plasmid pXO16.
