There is increasing evidence that microbial volatiles (VOCs) play an important role in natural suppression of soil-borne diseases, but little is known on the factors that influence production of suppressing VOCs. In the current study we examined whether a stress-induced change in soil microbial community composition would affect the production by soils of VOCs suppressing the plant-pathogenic o...

Among the millions of microorganisms inhabiting soils, some can be plant pathogens, meaning they become a disease to plants. Some diseases are more well-known than others. This is case clubroot, very atypical microorganism that infects cruciferous plants, such as cabbage, kale, canola, and common research thale cress. In this article, I will tell you about clubroot because there still lot disco...

The area used to grow high-value crops is currently decreasing because production in the same soil for many years increases soil-borne diseases that reduce crop yield and quality as well farmer income. Soil-borne disease effectively controlled by fumigation prior planting. In this study, five different types of soils had been tomatoes, watermelon, cucumber, ginseng ginger were collected from fi...

The behavioral and ecological factors involved in immune system evolution remain poorly explored. We present a phylogenetic analysis of white blood cell counts in primates to test three hypotheses related to disease risk: increases in risk are expected with group size or population density, exposure to soil-borne pathogens, and mating promiscuity. White blood cell counts were significantly grea...

Sweetpotato (Ipomoeae batatas (L.) Lam.) is an important food crop affected by several pests throughout the world, especially in tropical, subtropical, and temperate regions. Although Japan is relatively free from many serious sweetpotato pests, some pests, especially soil-borne pathogens, viruses, and insects such as plant-parasitic nematodes and weevils, cause severe damage in Japan. In this ...

Occupational exposure to a range of pathogens represents a serious risk to anaesthetists. The risk of transmission of blood-borne pathogens, such as human immunodeficiency virus (HIV) and hepatitis B and C, are well known, but occupational exposure also includes airborne pathogens such as tuberculosis. The risk of occupational infection with a blood-borne pathogen is proportional to three factors:
