Echinococcus granulosus Antibodies in Dogs and Breeder practices promoting spread of infection in Plateau State, Nigeria

Background: Echinococcosis caused by Echinococcus granulosus is a zoonotic disease of public health significance, but there have been few studies of the infection in dogs in Nigeria. This study aimed to establish the seroprevalence of E. granulosus in dogs in four Local Government Area of Plateau State, Nigeria. Methods: A total of 179 dog sera were examined for the presence of E. granulosus antibody using an ELISA kit between May to October 2017. Results; Eleven of the sera (6.1%) were seropositive with a prevalence of 7.4% and 2.3% for dogs less than 2 years and those above 2 years of age respectively. More male dogs (7.5%) than females (4.1%) were seropositive. Seroprevalence was associated with <2years than > 2 years dogs (OR=3.33, p=0.46) and male than female dogs (OR=1.90, p=0.53) but association were not significant. Dogs from Bassa had the highest seroprevalence (15.2%), followed by Mangu (5.9%), Kanke (4.8%) and Jos South (2.0%). Odds ratio showed an association which was not significant between Bassa (OR=3.3), Kanke (OR=2.50). Conclusion: This study shows that E. granulosus infection is present in dogs in some parts of Plateau State. More studies should be done to ascertain echinococcus infection in dogs in Nigeria to aid the formulation of control programmes to forestall its public health impacts.
