Popis: | Six clinical isolates of Pseudomonas cepacia (representing the five serotypes of the organism) were examined for the presence of 3-deoxy-D-manno-2-octulosonic acid (KDO) in their lipopolysaccharide (LPS). Purified LPS was examined for the presence of KDO by the thiobarbituric acid (TBA) assay and by gas chromatography. All strains possessed KDO. One strain possessed KDO that was detectable by the TBA assay after mild acid hydrolysis with 0.04 M H2SO4 at 100 degrees C for 20 min. The other strains also possessed KDO but it was only demonstrable by the TBA assay after strong acid hydrolysis (4 M HCl for 60 min at 100 degrees C). All six purified LPS preparations were shown to possess KDO by two separate gas chromatography procedures. LPS isolated from the six strains of P. cepacia was toxic for mice. |
