Summary of activities specifically related to the mandate of
OIE Collaborating Centres
1. Activities as a centre of research, expertise, standardisation and dissemination of techniques within the remit of the mandate given by the OIE
SEPRL is the U.S. Department of Agriculture’s primary facility for research on exotic and emerging viral diseases of avian species including avian influenza (AI), Newcastle disease (ND), avian metapneumovirus (aMPV), enteric viruses of poultry and Marek’s disease herpes virus
Major accomplishments for 2009 relative to international issues included:
Demonstrated that turkeys, quail, domestic ducks and geese can be susceptible to wild bird influenza viruses and such species can be entry points of such viruses into agricultural systems.
2.3% of samples collected from land-habitat birds in southern China (2004-2007) tested for avian influenza virus (AIV) using real-time reverse transcriptase polymerase chain reaction (RRT-PCR), indicating that species other than waterfowl can serve as hosts for the virus.
Triple reassortant H3N2 turkey-origin influenza viruses replicated and transmitted efficiently in turkeys but exhibited poor replication and transmissibility in chickens and ducks.
Three H5N1 high pathogencity (HP) AIV from chickens in Nigeria were determined to be genetically related to recent viruses from Europe and the Middle East, and produced systemic and severe disease in chickens typical of this lineage of viruses.
House sparrows were found to be highly susceptible to H5N1 HPAI viruses, but rock pigeons were resistant to infection and only shed low titers of virus for short periods of time indicating that house sparrows could play a role in dissemination of the virus among birds including poultry, but rock pigeons are unlikely to be important for the ecology of this HPAIV lineage.
The birds vaccinated with Newcastle disease viruses (NDV) vaccines made from isolates that were genetically similar to the challenge virus shed less virus in oral secretions and had fewer birds shedding virus than the birds vaccinated with vaccines made from viruses genetically divergent from the challenge virus suggesting using NDV vaccines genetically closer to field viruses may improve field protection.
NDV were obtained from recent outbreaks in the U.S., Mexico, Russia, Egypt, Dominican Republic, Belize, Peru, Vietnam and Pakistan were genetically similar to previously described viruses, but viruses from Dominican Republic were genetically different enough from the other viruses to be considered as new genotypes.
Muscovy ducks (Cairina moschata) had less protection after vaccination and longer duration of HPAIV challenge virus shedding than domestic ducks (Anas platyrhynchos) when using the same vaccine and vaccination protocol indicating new vaccine and vaccination protocols need development for Muscovy ducks.
By comparing different schedules of domestic duck (Anas platyrhynchos) vaccination, it was determined that vaccinating at 7 days and boosting at 21 days of age protected ducks against disease and mortality after a virulent H5N1 HPAI challenge at a month of age.
The functional Mx gene provided only partial protection to chickens against HPAI virus challenge.
There was demonstration of the lack of broad H7 vaccine protection between Eurasian, North American, South American and Australian lineages of H7 avian influenza viruses
2. Proposal or development of any procedure that will facilitate harmonisation of international regulations applicable to the surveillance and control of animal diseases, food safety or animal welfare
The RRT-PCR test for avian influenza virus H7 hemagglutinin was updated to detect newer strains of H7 viruses
The RRT-PCR test for influenza A virus matrix gene reverse primer was updated to improve sensitivity for detecting the pandemic H1N1 virus and works well in a duplex test with the original reverse primer to detect both avian influenza and the pH1N1 viruses
A polymerase chain reaction (PCR)-based diagnostic test was developed and validated for the detection of chicken- and turkey-origin enteric parvoviruses
3. Placement of expert consultants at the disposal of the OIE
David Swayne provided assistance to OFFLU through the Technical Group on Avian Influenza Vaccination in Indonesia.
David Suarez provided technical assistance on H5N1 HPAI virus sequencing and analysis to National Laboratory for Quality Production, Cairo, Egypt
David Swayne and David Suarez provided technical assistance to OFFLU on diagnostics and poultry studies on pandemic H1N1 virus.
David Suarez and Mary Pantin-Jackwood conducted studies and provided data on molecular changes in H5N1 HPAI viruses and vaccine efficacy and pathogenesis studies in ducks to Ministry of Agriculture, Vietnam
David Suarez, Qingzhong Yu, Darrell Kapczynski and Patti Miller provided technical assistance to ARRIAH (Vladimir, Russia) and Ivanovski Institiute (Moscow, Russia) on poultry disease research and on collaborative projects
Other activities related to the mandate
of OIE Collaborating Centres
4. Provision of scientific and technical training, within the remit of the mandate given by the OIE, to personnel from OIE Members
One scientist from Pakistan and one scientist from Egypt were trained in sequencing and phylogenetic analysis of avian influenza viruses, real-time RT-PCR and virus isolation through individualized two week training programs.
Two scientists from Georgia, one scientist from Afghanistan, two scientists from Azerbaijan, one scientist from Russia, two scientists from Morocco, two scientists from Libya, two scientists from Mongolia, one scientist from Kazakhstan and two scientists from Ukraine were trained in sequencing and phylogenetic analysis of avian influenza viruses, real-time RT-PCR, HI assays and virus isolation through individualized two week training programs.
Three scientists from Pakistan were trained in sequencing and phylogenetic analysis, real-time RT-PCR and basic virological techniques for Newcastle disease and avian influenza viruses.
A three day short course on RNA extraction, RRT-PCR and troubleshooting was held and attended by 21 scientists from Afghanistan (1), Brazil (2), Kazakhstan (2), Kenya (3), Mexico (1), Nigeria (3), Pakistan (1), Palestine (1), Russia (1), Yemen (1), Turkey (2), Morocco (2) and Egypt (1).
As part of an OFFLU research project, five scientist from Egypt have participated in a 9 month project in avian influenza vaccine seed strain selection and included training in RNA extraction and sequencing of NS and M genes for ten 2008 Egyptian H5N1 high pathogenicity avian influenza viruses, and phylogenetic analysis; and vaccine production and vaccination, separation of oil emulsion vaccines, challenge studies, antisera production, HI and AGID antigen production, antigenic cartography, egg inoculation, tissue culture techniques, and molecular diagnostics (sample processing, RNA extraction, RRT-PCR reactions and results interpretation, primer design) and introduction to the reverse genetics systems for avian influenza virus production.
5. Organisation of scientific meetings on behalf of the OIE
Organized the 7th International Symposium on Avian Influenza, April 5-8, 2009, University of Georgia, Center for Continuing Education, Athens, Georgia, USA. The symposium had 411 registered participants from 54 countries. The program included 79 oral and 122 poster presentations. A special half-day session dedicated to OFFLU was included. Co-chairs were David E. Swayne, Ian H. Brown and David Stallknecht.
6. Coordination of scientific and technical studies in collaboration with other laboratories or organisations
SEPRL has ongoing collaborations with personnel from the University of Alaska and the Wildlife Conservation Society for the collection of swab samples from numerous wild bird species in North America, Asia and South America. These samples are processed for AIV detection by SEPRL and isolates are characterized by gene sequencing
SEPRL conducted Indonesia AI vaccine efficacy studies and constructed a reverse genetic low pathogenic H5N1 vaccine seed strain. This project was in collaboration with Ministry of Agriculture in Indonesia, AAHL (Australia), FAO (Indonesia and Rome), OIE (Paris), USDA/APHIS and USAID.
SEPRL conducted Egyptian AI vaccine efficacy studies and constructed reverse genetic low pathogenic H5N1 vaccine seed strains. This project was in collaboration with National Laboratory for Quality Production (Cairo, Egypt), Central Laboratory for Evaluation of Veterinary Biologicals (Cairo, Egypt), FAO (Cairo and Rome), and USAID.
