a
The number before the dash identifies the donor cat; the number after the dash identifies the month p.i. when the serum was obtained.
b
Values shown are the geometric means of the titers obtained in two independent assays. −, no neutralizing activity detected; mean titers of <8 were not considered significant and were scored as negative.
