[Serological evaluation of the efficacy of an antirabies vaccine in field dogs in Tunisia].

We have vaccinated with an inactivated experimental vaccine, Rabi Rabta, prepared in lamb brain 52 dogs from the field in Tunisia and we tested by recommended serological methods the production of specific antibodies. The animals (35) received a boost injection after one year and the control of the immunological response was done on the same way after one month. This work done on 27 dogs showed very low serological data. A comparable batch of 42 dogs was immunised with a commercial vaccine with the same procedure; the results obtained from 17 dogs were not very different. This is apparently in contradiction with the success obtained by the National Program against Rabies launched in Tunisia since 1982.
