Recently, there have been fears that an influenza pandemic is approaching in the near future and the importance of preventing infection has often been discussed. The possibility of controlling the evolution of virulence has however received less attention. In the present paper, I first introduce the evolutionary ecology of infectious disease virulence based on the existing theoretical work and then explain three possible selection pressures that favor very serious virulence and suggest promising methods to reduce the effect of each. Most of these methods are consistent with methods to prevent the spread of infection, while one also emphasizes the importance of international cooperation in the elimination of poverty and conflict. I suggest thus that evolutionary ecological thinking has the potential to provide a new point of view in the control of infectious diseases.

To evaluate the effect of natto and soybeans on postprandial blood glucose level, a crossover study was conducted in 12 healthy male volunteers.<BR>Subjects were given a control meal (white rice), a natto meal (white rice with natto), or a soybean meal (white rice with steamed soybeans), and blood glucose level in each group was measured before and 15, 30, 45, 60, 90, and 120 minutes after intake.<BR>After both the soybean and natto meals, the blood glucose level at 60 minutes after intake was significantly lower than after the control meal. However, only the natto meal, and not the soybean meal, significantly suppressed the rise in blood glucose level at 60 minutes compared to the control meal. Furthermore, the area under the glucose curve from 0 to 120 min after the natto meal was significantly smaller than for the control meal.<BR>These results suggest that natto is useful for the control of postprandial blood glucose level.

There are many human infectious diseases derived from pathogenic viruses. In line with the infectious disease surveillance systems of Osaka City, the staff of our institute&prime;s department of microbiology seek to isolate and identify human pathogenic viruses from patient specimens using a number of routine methods. In the present review, I describe methods of pathogenic virus identification using the standard virus neutralization test and the latest methods using virus genome gene analysis, together with Japanese law on infectious disease.
