Serologic prevalence of antibodies against avian origin influenza virus in dogs referred to the Veterinary Clinic at Shiraz University

Abstract

The aim of this study was to determine the prevalence of exposure to avian origin influenza virus (AIV) in dogs referred to the Veterinary Clinic at Shiraz University. A total of 182 dogs were selected from cases at the Small Animal Clinic from the Veterinary Medicine School. Complete history and physical examination was performed and blood samples obtained and submitted for serologic testing (ELISA) for the detection of antibodies against AIV. Statistical analysis was performed to evaluate the association of factors (age, breed, diet, place, presence of other dogs, general symptoms, respiratory and gastrointestinal signs) with positive results. Eighty two out of 182 (45%) dogs were seropositive for antibodies against AIV. Although positive result were found more in shelter dogs or in dogs with general signs, no significant differences were seen in the evaluated factors and seropositivity. The results suggested that many dogs were exposed to AIV in the study population and could be asymptomatic so preventative procedures are mandatory. Additional research is needed for the detection of their serotype.
