we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and  fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...

In the course of conducting forensic analysis of human skeletal material, anthropologists are exposed to a number of biological and chemical hazards. This paper reviews the primary concerns in terms of infection or exposure. Handling of human tissue provides an avenue through which bloodborne pathogens may be transported. Scene recovery also includes a set of hazards through exposure to human, ...

There is increasing evidence showing that microbes can influence plant-insect interactions. In addition, various studies have shown that aboveground pathogens can alter the interactions between plants and insects. However, little is known about the role of soil-borne pathogens in plant-insect interactions. It is also not known how environmental conditions, that steer the performance of soil-bor...

Gaeumannomyces graminis var. tritici causes take-all disease, the most important root disease of cereal plants. Cereal plants are able to form a symbiotic association with soil-borne arbuscular mycorrhizal fungi which can provide bioprotection against soil-borne fungal pathogens. However, the bioprotective effect of arbuscular mycorrhizal fungi against soil-borne fungal pathogens might vary. In...

Exposure to the soil-borne pathogens Burkholderia pseudomallei and Burkholderia cenocepacia can lead to severe infections and even mortality. These pathogens exhibit a high resistance to antibiotic treatments. In addition, no licensed vaccine is currently available. A nanoscale platinum-containing titania photocatalyst (TiO(2)-Pt) has been shown to have a superior visible light-responsive photo...

Hyperdiverse forests occur in the lowland tropics, whereas the most species-rich shrublands are found in regions such as south-western Australia (kwongan) and South Africa (fynbos). Despite large differences, these ecosystems share an important characteristic: their soils are strongly weathered and phosphorus (P) is a key growth-limiting nutrient. Soil-borne pathogens are increasingly being rec...

With the rising awareness of the adverse effects of chemical pesticides, people are looking for organically grown vegetables. Consumers are increasingly choosing organic foods due to the perception that they are healthier than those conventionally grown. Vegetable crops are vulnerable to a range of pathogenic organisms that reduce yield by killing the plant or damaging the product, thus making ...
