Abstract
Background: Pestiviruses, Bluetongue and Akabane viruses are important pathogens of ruminants causing a variety of clinical and subclinical manifestations. These viruses can also cause infertility, abortion and fetal malformation in infected animals. Clinical and postmortem observations, together with epidemiological data, that may have also been confirmed by laboratory tests imply that these viruses distributed in Iran. Also, seroepidemiological studies indicate that these viruses are prevalent in susceptible population of the country. Aims: This cross-sectional study was performed to evaluate the seroepidemiological rate of Pestiviruses, Bluetongue and Akabane viruses in domestic susceptible population (cattle, sheep and goat) of Qazvin province. Materials and Methods: Using simple random sampling method, a total of 290 animals including cattle, sheep and goats in 30 Epidemiological Units (E.Units) were selected for sampling. Blood samples were collected from the animals as a specific questioner was also completed for each animal. The obtained sera were tested for antibodies against Pestiviruses, Bluetongue and Akabane viruses by using commercial competitive ELISA kits. The data description and seroprevalence rate were defined for each of the viruses. Also, association between seroprevalence rates and risk factors was evaluated by using univariate regression analysis. Results: At herd level, 96.67%, 43.34% and 20% of the E.Units were seropositive to Pestiviruses, Bluetongue and Akabane viruses, respectively. Also, the overall seroprevalence rate of these viruses was estimated to be 56.89%, 18.97% and 4.14%, respectively.
Conclusion: Compatible with the previous studies, these results also indicate that these viruses are prevalent in Iran. High prevalence of Pestiviruses, which are significantly prevalent in cattle and industrial farms, is particularly considerable point of this research. Comprehensive research on virology and epizootiology of these agents, establishing scientific and practical programs for prevention and control of these viruses, particularly Pestiviruses, is recommended.
