Antibody Response of Captive Cheetahs to Modified-Live Feline Virus Vaccine

The antibody response of cheetahs (Acinonyx jubatus) to modified live virus vaccine against feline panleukopenia (FPLV), herpes (FHV) and calici (FCV) viruses was assessed by means of an enzyme-linked immunosorbent assay (ELISA). In the first year of study, 82 cheetahs were bled pre-vaccination. Of these, antibody levels to FPLV were found in 100% of the animals. Only 54% were found to have antibodies to FHV and 99% had antibodies to FCV. One month after booster vaccination with the same vaccine, increased antibodies to FPLV, FHV and FCV were seen in 19 (58%), 18 (55%) and 25 (76%) of these animals, respectively (n = 33). In the second year of study, 65 cheetahs were bled pre-vaccination. Fifty three of these animals were negative for antibodies to FPLV while 28 were positive for FHV and 64 were positive for FCV. These animals were then bled 1, 2 and 6 mo post booster vaccination. The antibody levels to the various viruses showed different trends with time.
