In another experiment (data not shown), we checked the horizontal infection rates of the recombinant virus by evaluating goats in close contact (living in the same yards) with vaccinated goats; antibodies against CAV-2 or PPRV were not detected in the in-contact control animals, further ruling out the possibility of rCAV-2-PPRV-H shedding from experimental animals with the recombinant virus. The gene discussed is CAV2; the disease is infection.
