Lectin agglutination of thermophilic Campylobacter species

Abstract

Agglutination tests with lectins indicated differences in the surface composition of strains of the thermophilic (optimum temperature 42 degrees C) Campylobacter species C. coli, C. faecalis, C. hyointestinalis, C. jejuni and C. laridis. All strains examined were agglutinated by the protein-reactive agglutinins of Mangifera indica (mango) and Persea americana (avocado) and a large proportion was also agglutinated by the carbohydrate-reactive lectins of Canavalia ensiformis (Jack bean) and Triticum vulgaris (wheat germ). Reactions with other lectins varied widely between strains, even of the same species and serotype. Lectin agglutination may be useful as a supplementary procedure for characterizing individual Campylobacter isolates for epidemiological purposes.
