Implementation Plan

Towards the prevention and control of zoonoses, the COE program mainly deals with BSE, West Nile fever, influenza, SARS, rabies, echinococcosis, tick-borne encephalitis, and hantavirus infections, and performs the following research subjects of above zoonoses.

 
 
Program of Excellence for Zoonosis Control



 
(1) Development of early and rapid diagnostic methods:
IgM ELISA, immuno-PCR, and DNA array will be developed as rapid and early diagnosis of each zoonosis and the sensitivities and specificities will be evaluated.  Highly sensitive diagnostic method of prion disease will be developed for live animals.
   
(2) Development of vaccines:
Vaccines for each zoonosis will be developed and evaluated. The most appropriate vaccine for each zoonosis will be selected from the mucosal vaccines, replication incompetent virus vaccines, peptide vaccines, and DNA vaccines.
   
(3) Epidemiological investigations:
Positive areas for each zoonoses will be specified by sero-epidemiological survey of animal and human sera. Pathogens will be isolated from the samples collected from domestic animals, wild animals, mosquitoes and ticks.  From these data, the transmission cycles and perpetuation mechanisms of the pathogens will be revealed.  International surveillance system will be constructed and epidemiological information will be obtained through this system.  The information together with those collected in the center will be opened for public.
   
(4) Risk analysis:
According to epidemiological information, risk analysis for each zoonosis will be performed.  The prediction of outbreaks, prevention of the epidemic and eradication measure will be taken for zoonoses in Japan.  For zoonoses which may invade from abroad, the following preventive measures will be taken; estimations for risks of invasion and the route, and risk management system including the prevention of the invasion and the epidemic.
   
(5) Genetic characterization of pathogens:
Genes of pathogens will be sequenced and phylogenetically analyzed.  From the data, the evolutions and origins of the pathogens will be estimated.
   
(6) Pathogenesis:
Molecular basis of pathogenesis of each of the pathogens will be analyzed using animal models.  In particular, the pathogenesis of encephalitis and encephalopathy will be examined in West Nile fever, tick-borne encephalitis, and influenza.  That of hemorrhagic manifestation and renal failure will be studied in hantavirus infection.
 
By putting all the results together, the preventive measures will be established for the control of zoonoses causing problems in Japan and abroad.
