a
Serologic antibody responses to the 27- and 17-kDa C. parvum antigens determined as described by Priest et al. (53).
b
Percentage of the total number of P2 antibody responses (n = 45) that were present in each category.
c
Two oocyst detection events overlapped with separate antibody responses to the P2 protein and to the 27- and 17-kDa antigens.
d
Includes one consecutive antibody response to the 27- and 17-kDa antigens, as defined previously (53).
