[The adhesive activity of Klebsiella pneumoniae controlled by plasmid 55 MD].


In K. pneumoniae clinical strains a nonconjugative plasmid, denoted as pAdh-55 and responsible for their adhesive activity with respect to HEp-2 cells, was detected. The comparison of genetically related pairs of K. pneumoniae strains differing in the presence of pAdh-55 revealed that the loss of this plasmid by bacteria was accompanied by a decrease, and… (More)
