RESUMO
Strains of Campylobacter jejuni and Campylobacter coli were characterized and grouped by their distinct reaction patterns with lectins. Heating of the Campylobacter cultures to 100 degrees C and holding for 30 to 60 min greatly enhanced their reactivity with lectins and permitted the grouping of all but 3 of 155 cultures tested in this study without interference of autoagglutination and other nonspecific activities. The lectin reaction patterns of the heated cultures were stable and reproducible. They were strain specific and independent of the heat-stable antigenic types. The lectin-reactive sites of C. jejuni and C. coli may be useful as additional markers for strain characterization. Based on these observations, a simple slide agglutination procedure is described for differentiating strains of C. jejuni and C. coli by their interaction with a selected group of commercially available lectins.
