Abstract
Lipoglycans from mycoplasmas possess the ability to induce the elaboration of procoagulant activity. This represents a third endotoxic property for these polymers, in addition to the pyrogenicity and clotting of Limulus lysate reported previously. Lipoglycans from three species of Acholeplasma (A. axanthum, A. granularum, and A. oculi) stimulated the elaboration in vitro of procoagulant activity by human mononuclear cells to differing extents. Two serotypes, 3 and 4, of Ureaplasma urealyticum also exhibited this stimulatory activity. The activities of lipoglycans tested were, in decreasing order, A. oculi greater than U. urealyticum type 4 greater than A. axanthum greater than U. urealyticum type 3 greater than A. granularum.
