a
Reciprocal of the highest dilution of serum giving total agglutination. Serum was obtained by using whole cells of strain E86 as an antigen.
b
Reciprocal of the highest dilution of serum which produced a reaction at an optical density at 405 nm of >0.2 after subtraction of the control values. Serum was obtained by using whole cells of strain E86 as an antigen.
c
Reciprocal of the highest dilution of serum which produced a reaction at an optical density at 405 nm of >0.2 after subtraction of the control values. Serum was obtained by using LPS of strain E86 as an antigen.
d
NT, not tested.
