| Research Abstract |
The purpose: By a wide-ranging movement of the person and food according to the world-wide borderlessness, various infectious diseases might spread widely. The, terrorism issue is added too, resulting that an international prevention for the infectious diseases should be essential Because it becomes big social issues if these infectious diseases invade Japan, it is necessary to collect various information for the infectious diseases in foreign countries and to strengthen the governmental crisis- management system. In addition, the risk analysis associated with the food -borne diseases would be essential. Since most of them are zoonotic diseases, a special research group associated with the food hygiene. Therefore, we focus on the epidemiological studies of zoonotic diseases and food hygiene in Asia countries, and also on the development of their rapid detection methods.
Results: By a collaborated research with Thailand, we collected various foods as chicken meats, pig meats, beef meats,

scrimps and oyster, to check their contamination by food pathogens like Salmonella, Campylobacter, Listeria, E. coli and etc. Also, we studied on their antibiotic resistance. As the results, the situation of the contamination showed same with Japan. Moreover, the recombination NP protein of avian influenza virus in E. coli was made and the latex agglutination methods to detect the virus antbody, in order to study its effect and availability in Asian countries. The method is available to detect influenza virus A antibody among all animals. However, there is no problem in avian serum, but since the non-specific reaction was occurred in duck serum, we could not remove the background. We are trying to start the epidemiological study in the Asian countries. In addition, the epidemiological surveillance concerning the infection history of toxoplasmosis among human and animals was done by the latex agglutination assay in Vietnam where the pig farming was main, resulting that the positive rate of the toxoplasmosis antibody rose in pig with the age, and the pig of about 70 percent or more was positive at the shipment stage, and the antibody possession rate was high. However, the antibody possession rate in human was lower in Japan. Finally, we studied on the hygienic situation in the slaughter houses in Vietnam, resulting that the situation was more serious than one Japanese, situation and that the immediate hygienic countermeasure would be essential in the country.
