title: Opsonin independent interaction of Klebsiella strains with human polymorphonuclear leukocytes.
abstract: Nine encapsulated Klebsiella strains with different types of fimbriation and their nonencapsulated mutants were tested for their stimulatory potency for human polymorphonuclear leukocytes in the absence of opsonins. The luminol chemiluminescence assay was used for these experiments. It could be shown that the interaction between Klebsiella bacteria and human leukocytes is rather complex depending not only on the presence of capsules but also on the hydrophobicity of Klebsiella surface and on the type of fimbriation existing.
