IMMUNOLOGIC REAGENTS TRANSFERRED FROM THE INTERNATIONAL LIVESTOCK RESEARCH INSTITUTE, NAIROBI, KENYA TO PLUM ISLAND ANIMAL DISEASE CENTER
Foreign Animal Disease Research
2012 Annual Report
1a.Objectives (from AD-416):
The objective of this project is to import cells producing monoclonal antibodies specific for bovine cells produced and characterized at the International Livestock Research Institute (ILRI). This requires ILRI to determine the viability of the antibody cell lines and ARS, PIADC to test for the presence of foreign animal diseases in vivo. Once cleared, the cell lines will be made available to colleagues in Foot-and-Mouth Disease free countries and/or deposited in the American Tissue Culture Collection for general distribution. These antibodies will become available to scientists in the United States to facilitate analysis of bovine immune responses and vaccine development.
1b.Approach (from AD-416):
ARS, PIADC and the International Livestock Research Institute, Nairobi, Kenya (ILRI) will determine a list of high-priority cell lines. ILRI will test for viability and antibody production. These cell lines will be transferred to PIADC and safety tested at PIADC under BSL-3 conditions. Upon successful safety testing, the cell lines will be prepared for distribution to colleagues in North America and Europe through the use of a material transfer agreement between ILRI, ARS and recipient.
During FY 2012, the first 30 of these lines were transferred from the International Livestock Research Institute in Nairobi, Kenya to USDA-Plum Island Animal Disease Center and stored in liquid nitrogen. Safety testing protocols were updated and approved by the Center for Import and Export-APHIS and the samples safety tested. Random samples of each of the 30 cell lines were chosen by staff from USDA-APHIS for safety testing. All tests were uniformly negative for the presence of any disease agents and the samples are ready to be released for distribution. Appropriate permits for transfer of these cell line to second parties have been initiated.
The balance f the cell lines have been thawed and tested at ILRI. New aliquots have been freshly frozen and prepared for shipping to Plum Island Animal Disease Center. USDA Plum Island is submitting permit applications to USDA-APHIS for the import of these cell lines. We anticipate having all cell lines received, stored and ready for safety testing by the end of the calendar year, 2012.
