Abstract

Objective: To screen for rabies virus (RABV) antibodies in apparently healthy confined, hunting and roaming dogs by a community-based approach. Methods: Sera from 230 (80 confined, 92 hunting and 58 roaming) dogs in some urban and periurban communities in Ogun and Oyo states, Southwestern Nigeria were screened for RABV antibodies using the indirect ELISA method. Results: Analysis of administered questionnaires showed that of 80 confined dog owners, 37 were aware of anti-rabies vaccination (i.e. they were informed) while 17 were negligent and 26 uninformed. Of the 230 sera tested, only 13 (5.7%) from vaccinated confined dogs in Oyo state were positive (i.e. had optimal RABV antibody titres) (mean 0.54, 95% CI: 0.42–0.67) while all confined dog sera in Ogun state were negative. Eleven (12.0%) and 14 (24.1%) of the hunting and roaming dogs respectively had sub-optimal RABV antibody titres while the rest were negative. Conclusions: Evidently, these groups of dogs are a totally unprotected and susceptible dog population that can serve as potential reservoirs of RABV in the study area. Responsible pet ownership, vaccination of hunting and roaming dogs, and community-based active rabies surveillance are therefore advocated in Nigeria.
