- aSubtypes of type-2 fimbriae, types-2:1 to 2:3, among Actinomyces species based on different hybridization patterns of strains with fimA-derived DNA probes and binding patterns to carbohydrates, red blood cells and bacterial partners [14].
- b Saccharide specificity and receptor ligand (GL= glycolipid, GP = glycoprotein) for each fimbriae subtype or reference strain [20, 28].
- c Hemagglutination (HA) patterns for each fimbriae subtype or reference strain. Score 0 marks no HA and score 4 strong HA. Similar HA results were obtained with goat and chicken erythrocytes (data not shown).
