^a Foetuses were identified by their position in the uterus. L = left horn; R = right horn.

Numbering is in sequence from ovary to cervix.

^b NI = not inoculated.

^c L6 and R5 were adjacent to each other.

^d L2 and R4 were adjacent to each other.

^e L1 and R3 were adjacent to each other.

^f PCR amplification of the Rep gene.
