  • Title: [Klebsiella pneumoniae adhesion to epithelioid cells in vitro].

    Abstract:
    The adhesion of K. pneumoniae K24 capsular strain No. 6723 onto subcultured epithelioid human kidney cells RN was studied overtime by light microscopy and by transmission and scanning electron microscopy. To find out the bacterial capsule and glycocalyx of epithelioid cells, the method of staining the samples with ruthenium red was used, this stain producing the coloration of extracellular acidic mucopolusaccharides . The bacteria were found to attach to the qlycocalyx of epithelioid cells by means of protruding areas on the capsule which retained its form and size after both stabilization with ruthenium red and standard glutar -osmium fixation. Under the action of the bacteria epithelioid cells were found to round off, become longer and increase the number of processes. At the sites of contact with the bacteria specific short cytoplasmic processes serving for the attachment of K. pneumoniae cells were discovered.
