P. Schuster et al., Comparative immunogenicity and efficacy studies with oral rabies virus vaccine SAD P5/88 in raccoon dogs and red foxes, ACT VET HU, 49(3), 2001, pp. 285-290
A comparative study of immunogenicity and efficacy of the oral rabies virus
vaccine SAD P5/88 in raccoon dogs and foxes was conducted. The raccoon dog
s received 10(6.9) (n = 6), 10(6.3) (n = 6) or 10(5.7) FFU SAD P5/88 (n = 5
) by direct oral application, and subsequently all animals seroconverted. T
he foxes received 10(7.2) (n = 4), 10(6.2) (n = 4), 10(5.2) (n = 4) and 10(
4.2) FFU SAD P5/88 (n = 5) by the same route. On days 106 and 196 post vacc
ination 10 raccoon dogs and 16 foxes were challenged with a relevant street
virus, respectively. All 10 raccoon dogs vaccinated with 10(6.3) (n = 5) o
r 10(5.7) FFU SAD P5/88 (n = 5) survived the challenge, whereas all control
animals (n = 5) died of rabies. Two foxes vaccinated with 10(4.2) FFU and
one fox vaccinated with 10(5.2) FFU died of rabies on day 7, 17 and 12 post
infection, respectively. Also all control foxes succumbed to rabies. Our f
indings demonstrate that SAD P5/88 is not only an effective vaccine for ora
l vaccination of foxes but also for that of raccoon dogs.
