Efficaciousness of Sterne 34F-2 strain of Bacillus anthracis vaccine in cattle for anthrax control program in Bangladesh

Live spore Sterne 34F-2 strain of Bacillus anthracis vaccine is being used to control anthrax disease in Bangladesh. After produced this Livestock Research Institute (LRI) under the Department Services (DLS), it distributed at farmers level through district and Upazila Offices. In these distribution pathways, has been transported stored for a few days each station. The present study was carried out evaluate humoral immune response measure impact existing transportation storage systems on immunity status. For that total 60 cattle were randomly selected , divided into three groups vaccines collected from points. Serum samples before after 1st month, 4th 7th 10th, 13th month vaccination respectively antibody blood monitored. optical density converted ELISA units (EU) express vaccinated animals. It significantly increased above protection (1.00) year. Before vaccination, average unit serum sample 0.18± 0.01, raised protective within one continued up chi-square test (95% confidence level), there no significant difference (p<.05) among means points studied animal. found be efficacious protect animals rural areas due facilities.
