The two serotyping schemes for the detection of heat-stable antigens of Campylobacter jejuni and Campylobacter coli use the same strains for antiserum production but differ in the detection systems used for identifying agglutination. The Penner method uses passive hemagglutination (PHA) while the Laboratory of Enteric Pathogens method uses the same antisera(More)
The role of lipopolysaccharide (LPS) in the serotyping of Campylobacter jejuni based on heat-stable antigens was examined using SDS-PAGE and a silver stain for carbohydrate. None of the 32 type strains of Camp. jejuni expressed long-chain LPS. Rabbit antibodies, prepared to 10 selected strains of Camp. jejuni, reacted with surface-exposed carbohydrate(More)
Using the multiresolution ability of wavelets and effectiveness of singular value decomposition (SVD) to identify statistically robust parameters, we find a number of local and global features, capturing spectral correlations in the co- and cross-polarized channels, at different scales (of human breast tissues). The copolarized component, being sensitive to(More)
