Identification of Unknown Turfgrass Pathogens: Kochs Postulates
نویسنده
چکیده
History In 1876, a country doctor in Germany by the name of Robert Koch developed the first conclusive empirical evidence that a particular microbe causes a particular disease. Although he was working on anthrax, a deadly disease of warm-blooded animals (caused by the bacterium Bacillus anthracis), the procedures he laid out for determining the pathogenicity of a microorganism (in other words, its ability to cause disease) are still in use today. These procedures are commonly referred to as "Kochs postulates." Although the theoretical criteria for establishing pathogenicity in microbes had been laid down as early as 1840, Koch was the first to successfully apply these criteria experimentally. He went on to isolate the tuberculosis bacillus (for which he was eventually awarded a Nobel Prize) and the bacillus causing cholera.

The relationships among the chemical, physical and biological aspects of compost and their role in suppression of turfgrass pathogens are reviewed. The composting process, mediated by microbial activity, is aected by physical and chemical characteristics which include temperature, aeration, moisture content, C:N ratio and pH. In the absence of parameter restrictions, the microbial community fo...

Over 100 years ago, Robert Koch introduced his ideas about how to prove a causal relationship between a microorganism and a disease. Koch's postulates created a scientific standard for causal evidence that established the credibility of microbes as pathogens and led to the development of modern microbiology. In more recent times, Koch's postulates have evolved to accommodate a broader understan...

The Microbiology of Turfgrass Soils
Most turfgrass managers do not have a strong understanding of turfgrass soils, particularly the biological aspects. Certainly most know that living things, such as worms and insects can reside in soil, but they’re not sure where in the soil they live or what they live on. In fact, it might be safe to assume that most turfgrass managers consider soil to be a mysterious world below the turfgrass ...

BACKGROUND Turfgrass species are agriculturally and economically important perennial crops. Turfgrass species are highly susceptible to a wide range of fungal pathogens. Dollar spot and brown patch, two important diseases caused by fungal pathogens Sclerotinia homoecarpa and Rhizoctonia solani, respectively, are among the most severe turfgrass diseases. Currently, turf fungal disease control ma...
