SEROPREVALENCE OF INFLUENZA A IN SWINE POPULATION OF RANGAMATI AND KHAGRACCHARI DISTRICTS

Abstract

The serological investigation was carried out to determine the seroprevalence of influenza A in swine population Rangamati and Khagracchari districts of Bangladesh by using indirect ELISA and Identification of significant risk factors associated with Influenza A virus Epidemiology. A total of 90 sera samples of swines from different areas of Rangamati and Khagracchari districts of Bangladesh from January 2013 to December 2013.All sera samples were examined for the detection of antibodies of influenza A virus by indirect enzyme linked immunosorbant assay using commercially available kits. The seroprevalence of influenza A was 15% in Rangamati district, 10% in Khagracchari district. The overall seroprevalence between the aforesaid districts was recorded 12.22%. The investigation exhibit highest seroprevalence was found in Rangamati district (15%) and the lowest seroprevalence was (10%) found in Khagracchari district. The seroprevalence rate of influenza A was found 14.29% in male pigs and 9-76% in female pigs. The seroprevalence of influenza A was studied based on age and It was observed that 11-5% seroprevalence was found in grower pigs, 12:°5% in fattening pigs and12:5% in adult pigs. The investigation revealed that the highest (12:-5%) prevalence was found in fattening and adult pigs and the lowest prevalence was found in grower pigs
