a
Op, opaque; Tr, transparent. For serotype 6A (Op and Tr), values are the means of triplicate determinations of seven independent experiments; for 6B and 18C (Op and Tr), values are the means of triplicate determinations of two independent experiments; and for 23F (Op and Tr), values are the means of triplicate determinations of three independent experiments.
b
UI, unsaturation index, defined as the weighted average of the number of double bonds per fatty acid.
c
Unidentified isomer.
