Part I: 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

Research

a. AAHL is a national laboratory facility for the biocontainment of foreign animal diseases and new and emerging animal diseases and viral zoonoses, operating at BSL3 (enhanced) and BSL4. It provides a rapid diagnostic capability and outbreak diagnostic surge capacity through a Diagnosis, Surveillance and Response group and conducts research in to the major transboundary animal diseases and viral zoonoses under the theme of transforming animal biosecurity. Work is directed towards 3 main objectives: Reduction of Disease Emergence or Invasion Risk, Mitigation of Disease Impact through Decision Support for Limiting Disease Spread and Mitigation of Disease Impact through Modification of the Host Response.

b. Research dealing specifically with emerging infectious zoonotic diseases includes:

· development of novel antiviral treatments for Henipavirus infections including passive immunotherapies

·  optimization of novel Henipavirus vaccines

·  development of an improved diagnostic capability for Henipavirus infections including stall-side tests

·  establishing reverse genetics systems for henipaviruses

·  establishment and use of continuous bat cell lines for host-virus interaction and immunological studies

·  comparative pathogenesis study on different strains of Hendra and Nipah viruses with a focus on transmission mechanisms

·  optimization of the ferret model for henipavirus research and vaccine/therapeutics trials

·  study of Paramyxovirus genetic systems

·  pathogenesis studies of SARS Coronavirus in bats

·  pathogenesis studies of Reston ebolavirus in pigs

c. AAHL is undertaking various projects relating to AI pathogenesis and studies of AI vaccines and vaccination.

· Challenge models of H5N1 infection have been developed in chickens, ducks, ferrets and mice. Vaccine efficacy testing has been conducted for vaccine manufacturers and the protective effect of LPAI H5N1 is being assessed in ducks and chickens.

·  Comparative pathogenesis studies are being conducted both with field strains of H5N1 from various countries and species and with AI viruses constructed using reverse genetics (in collaboration with US and European research organisations).

·  Two major studies with an international poultry breeding company have commenced; one using transgenic techniques to develop poultry with an enhanced immune system that will be substantially resistant to AI infection and another to develop anti-viral therapeutics.

·  Evaluation of the anti-viral properties of commercial chemical compounds is also being conducted. The relative susceptibility of AI isolates from various Southeast Asian countries to the major influenza antivirals is being tested in an ongoing study.

·  A molecular diagnostic test for rapid identification and differentiation of important poultry viruses (infectious bursal disease virus, Newcastle disease virus, avian influenza) is under development.

·  Wild bird isolates of avian influenza viruses from Australia are being sequenced and analysed.

· Epidemiological studies in Indonesia and Vietnam have commenced investigating AI transmission in markets, AI infection in ducks, and the impact of vaccination on AI transmission in both commercial and village sectors.

d. Work on foot and mouth disease includes:

· development of new diagnostic approaches and reagents

·  Modelling of issues related to the control of biosecurity emergencies, particularly through development of understanding of livestock marketing systems in Australia

·  Epidemiological studies of effectiveness of foot and mouth disease control programs in Vietnam

·  Management of classical swine fever and foot and mouth disease at the village level in Laos

e. Wildlife disease research is continues on:

· Etiology and diagnostic markers for Tasmanian Devil Facial Tumour

·  Koi herpesvirus as a potential biological control agent

f. Research on other diagnostic technologies and test development includes

· Evaluation of rapid molecular detection and characterisation systems for risk evaluation of unknown viruses isolated in Australia

·  Rapid characterisation of unknown viruses using microarray hybridisation and PCR-select-subtraction and mass (454) sequencing

·  Development and production of immunological reagents and tests for emerging infectious diseases using recombinant antibody technology

·  Development of diagnostic tests for abalone herpesvirus and applying these in transmission trials and surveillance

Expertise

·  In addition to the specific missions by AAHL staff listed under section 3 below, AAHL’s Dr. Linfa Wang serves as a member of the WHO SARS Reference and Verification Laboratory Network

·  With respect to terrestrial animal disease, AAHL is a designated OIE Reference Laboratory for Hendra and Nipah Virus Diseases, Bluetongue Disease, Newcastle Disease and Avian Influenza. See separate reports.

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

AAHL has been collaborating with the OIE in reviewing approaches and standards to diagnostic test validation. Dr Axel Colling attended the OIE ad hoc Group Meeting on validation of diagnostic assays at the OIE headquarters in Paris, France between Jan 20-22nd 2010.and was invited to present a paper on Validation of Diagnostic Assays: OIE General Principles and OIE Procedure at the 2nd Global Conference of OIE Reference Laboratories and Collaborating Centres in Paris on 21-23rd June 2010. As Chair of the OIE ad hoc working group on Diagnostic Test Validation, he subsequently led discussions of the recent developments in the area of test validation during an FAO/IAEA/OIE consultants meeting at the IAEA/FAO Joint Division in Vienna prior to presenting the new OIE methods and procedures for diagnostic test validation at the 1st Congress of the European Association of Veterinary Laboratory Diagnosticians (EAVLD), Lelystad, the Netherlands 15-17 September, 2010.

These activities are leading to proposed new sections and approaches in the OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals.
