Annual reports of OIE Reference Laboratories and Collaborating Centres, 2010 1 Foot and mouth disease
Part I: Summary of general activities related to the disease
1. Test(s) in use/or available for the specified disease/topic at your laboratory
i) Virus isolation on IRP1 and RM cells to detect presence of virus in samples.
ii) Antigen ELISA typing to determine serotype
iii) Antigen titration to determine infectivity titre of the field strain for Cross serum neutralization test (CSN).
iv) Cross Serum Neutralization Test to determine the r1 value of the existing vaccine strains against the circulating field strain.
v) RT-PCR and Sequencing for molecular characterization of the virus.
vi) Liquid Phase Blocking ELISA-screening for FMD antibodies for post vaccine monitoring in vaccinated animals and for FMD surveillance.
Test For Specificity Total
LPBELISA Antibody Group 927
ELISA Antigen Group 350
VN Antibody Type 18
IRP1 and RM cell culture Virus isolation 409
2. Production and distribution of diagnostic reagents
Amount supplied nationally Amount supplied to other Type of reagent (including for own use) countries
Control positive serum 3000 ml 1000 ml
Inactive Antigens for ELISA tests 200 ampoules of 1ml for each of 30 ampoules of 2ml for each of Serotypes SAT 1, 2, 3, A and O Serotypes SAT 1, 2, 3,
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
a) Establishment and maintenance of a network with other OIE Reference Laboratories designated for the same pathogen or disease and organisation of regular inter-laboratory proficiency testing to ensure comparability of results
Participated in Proficiency tests for FMD Reference laboratories network organised by the FMD FAO World Reference laboratory at Pirbright UK.
2 Annual reports of OIE Reference Laboratories and Collaborating Centres, 2010 Foot and mouth disease
Collected oropharyngeal scrapping samples from buffaloes in SADC countries (Zimbabwe, Zambia, Malawi, Tanzania, and Mozambique) for virus characterisation and vaccine matching in collaboration with SADC-TADS project, OVI and FAO WRL Pirbright.
b) Organisation of inter-laboratory proficiency testing with laboratories other than OIE Reference Laboratories for the same pathogens and diseases to ensure equivalence of results
Organised LPBE backstopping missions for the SADC region FMD laboratories visited five laboratories in the region (Zambia, Zimbabwe, Mozambique, Swaziland, and Namibia) to ensure that they are able to carry out the harmonised LPBE method in their laboratories. Report on these backstopping missions are available at http://www.fao-ectad-gaborone.org
4. Preparation and supply of international reference standards for diagnostic tests or vaccines
Supplied validated SAT 1, 2 and 3 test viruses to Instituto Terramo in Italy
Supplied validated inactivated antigens for SAT 1, 2, 3 to SADC laboratories for post vaccination seromonitoring
5. Research and development of new procedures for diagnosis and control
Currently work is in progress to come up with the FMD virus databank of circulating strains in the region. This will aid in phylogentic analysis of strain origin and or relation. Post vaccination antibody titres have been determined for up to 120 days for SAT 1, 2 and 3 from several countries in the SADC region.
6. Collection, analysis and dissemination of epizootiological data relevant to international disease control
Virus surveillance carried in buffalo samples. Buffalo probang samples collected from Zimbabwe, Zambia, Tanzania, Mozambique, Angola and Botswana. Virus characterisation and vaccine matching in progress.
Responded to outbreak technical assistance request in Botswana and Cameroon. Samples collected, epidemiological assessment done and recommendations on control measures including vaccination regimes were made.
7. Maintenance of a system of quality assurance, biosafety and biosecurity relevant to the pathogen and the disease concerned
Maintained compliance against ISO 9001:2008 quality management standard requirements
Initiated preparation for implantation of ISO 17025 accreditation
Maintained implantation of Health Safety and Environment policies and procedures
8. Provision of consultant expertise to OIE or to OIE Member Countries
Responded to outbreak technical assistance request in Botswana and Cameroon. Samples collected, epidemiological assessment done and recommendations on control measures including vaccination regimes were made. Dr G Thobokwe attended the FMD Reference laboratories network meeting in November at WRL Pirbright

Participated in the organising and hosting of FAO/OIE PCP meeting for the SADC region held in Gaborone March 2011
12. Participation in international scientific collaborative studies
Collected field samples from Cameroon for analysis and vaccine matching prior to advising on the vaccination programme
