ABSTRACT
Rabies is a viral zoonosis caused by the Lyssavirus, and dogs are the primary host and reservoir. For the international movement of pets, rabies-free countries require a rabies quantification before importing animals, which varies significantly. The objective of this study is to investigate the reasons for variations in antibody titers in dogs. Data from 848 dogs exported from Morocco was collected. The results revealed that too-old dogs (over six years) or too young (under four months) are also less likely to respond to vaccination than dogs that are four months to six years old. A dog receiving a booster dose is better immunized than a dog receiving a single dose. On the other hand, the time interval between the last vaccination and the time of sampling also affected the titer. The longer the interval, the lower the titer measured, and this effect becomes more pronounced when the interval exceeds 60 days. The sex did not appear to affect the rabies antibody titer. Many factors influence the antibody titer of rabies. Thus, a double primary vaccination is strongly recommended in a rabies-endemic country like Morocco.
