Part II: Activities specifically related to the mandate
of OIE Reference Laboratories
3. International harmonisation and standardisation of methods for diagnostic testing or the production and testing of vaccines
EIA serum panels are prepared and used in annual certification of approximately 500 laboratories in the United States of America. These panels are available to other countries upon request. The OIE Reference Laboratory participated in an international quality assurance EIA antibody panel test supplied by the Australian National Quality Assurance Program (ANQAP) and worked with ANQAP regarding discrepant test results.
4. Preparation and supply of international reference standards for diagnostic tests or vaccines
Reference Standards provided are listed in Reagents section (#2). No OIE recognized reference standards were produced.
5. Research and development of new procedures for diagnosis and control
The Reference Laboratory provided consultation and participated in pre-license evaluation of a new EIA ELISA test kit for a commercial company. In the United States, EIA antibody detection ELISA and AGID diagnostic kits undergo final evaluation for licensure by the United States Department of Agriculture’s Center for Veterinary Biologics. Licensed diagnostic kits are available commercially from several manufacturers. Proficiency panels for EIA are provided to the Center for Veterinary Biologics, USDA, for use in diagnostic test evaluations. No EIA vaccine is approved for use in the United States of America.
6. Collection, analysis and dissemination of epizootiological data relevant to international disease control
The number and location (state) of EIA positive equids is compiled each year by the United States Department of Agriculture, Animal and Plant Health Inspection Services, National Animal Health Surveillance System.
This data is available at: http://www.aphis.usda.gov/vs/nahss/equine/eia/eia_distribution_maps.htm.
7. Provision of consultant expertise to OIE or to OIE Members
Laboratory personnel respond to technical queries from OIE Members as requested. Summary data on EIA proficiency panels is provided to OIE Members participating in proficiency panel testing.
8. Provision of scientific and technical training to personnel from other OIE Members
No requests for scientific and technical training on EIA were received from OIE members.
9. Provision of diagnostic testing facilities to other OIE Members
Diagnostic assistance was provided to France following detection of an EIA positive horse on standard pre-import serology submission. The laboratory confirmed reporting of the positive results, by France, to OIE. Samples from numerous OIE member countries were tested for EIA prior to animal movement to the United States. The World Equestrian Games (WEG) was held in the United States during 2010. The Reference Laboratory provided pretesting of over 400 samples from horses in OIE Member countries to assure they would successfully be allowed to enter the United States for the WEG. The Reference Laboratory also provided the EIA testing for all WEG horses entering the country by plane at the various US import centers, including a temporary import center constructed for the WEG competition horses.
10. Organisation of international scientific meetings on behalf of OIE or other international bodies
None.
11. Participation in international scientific collaborative studies
None.
12. Publication and dissemination of information relevant to the work of OIE (including list of scientific publications, internet publishing activities, presentations at international conferences)
None.
13. Inscription of diagnostic kits on the OIE Register
i) Did you participate in expert panels for the validation of candidate kits for inscription on the OIE Register? If yes, for which kits?
This activity was not conducted in 2010.
ii) Did you submit to the OIE candidate kits for inscription on the OIE Register? If yes, for which kits?
This activity was not conducted in 2010.
