Brucella canis infection is a neglected zoonotic disease and its seroprevalence in dogs and at-risk humans has not been previously studied in several countries including Jordan. The main aim of this study was to determine the seroprevalence and identify risk factors of B. canis infection in police, breeding and stray dogs and in at-risk humans in Jordan. A total of 169 sera samples from apparently healthy dogs and 185 samples from apparently healthy people (85 from dog handlers and 100 from the general population) were tested in the study. Antibodies against B. canis were tested using the canine D-Tec® CB Rapid Slide Agglutination Test (RSAT) kit with secondary 2-mercaptoethanol (ME-RSAT). Overall, 8.3% of the dog sera samples tested positive to antibodies against B. canis, and 37.8% of stray dogs tested positive. Seroprevalence was higher in male dogs than in females. Furthermore, none of the tested human samples was positive to antibodies against B. canis. There was a significant association between seropositivity and the type of dog. The study reports preliminary findings that suggest the presence of B. canis among stray dogs in Jordan. Thus, preventive measures should be taken to control the transmission of this pathogen from stray dogs to other dogs and humans as well.
