Plant pathogens and diseases

by pathogens originating from animals like measles and smallpox pandemics like the Justinian plague, Black Death,yellow fever, HIV, and SARs originated from animals past focus has always been on reacting to the disease not preventing it although that has changed in recent years with and inoculations for some diseases. Many people in Africa eat bushmeat like chimpanzees and monkey with a spread the ebola infection in recent years as these animals were hunted or handled. The ecology of diseases…

symbiotic relationship between plants and fungi is an essential one for benefiting fully from Mycorrhizae, which then helps the land plants absorb the essential nutrients such as phosphorus and nitrogen. The interaction between plants and microbes allows for essential functions of the plants such as growth, germination and health of the plant, as well as for helping the plant fight off disease and stress. The beneficial fungi being present will also somewhat prevent disease-causing fungi…

Flies more germ-laden than suspected A group of scientist has recently discovered that flies carry more diseases than suspected. The Bristles in a fly’s body attracts the bacteria from where the flies have been. Flies are able to spread bacteria from place-to-place on their legs, feet, and its wings, experiments have shown. In fact, researchers have discovered that for every step taken with a fly it can transfer live bacteria from place-to-place. Many of the bacteria that flies carry are…

is caused by human activity, and one example of a human caused mass extinction is the wipeout of several pollinator species due to the uprooting of pollinated varieties of apples. These plants were uprooted because there was a demand for specific apples in the 1980s, so farmers made room for these particular plants by getting rid of the others (Assessment, Millennium…

able to withstand the effects of drying or freezing temperatures, and can lose viability if stored for long periods of time. Therefore, it was believed that the mango was dispersed to other parts of the world as a ripe fruit, seedling, or a grafted plant by European colonists during the 15th and…

cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism. Genetic engineering has applications in medicine, research, industry and agriculture and can be used on a wide range of plants, animals and microorganisms. The following are the applications…

gene technology) performs this modification. The specific genes selected from one organism are transferred to another within different species such as animals, plants, bacteria, and so on, resulting in a modified organism which carries enhanced desirable traits. These traits include more nutrients, faster growth, stronger resistance to diseases and insects, longer storage life, and other purposes. For instance,…

plays an imperative role in pathology, enabling the diagnosis and treatment of many diseases abundant within the human population. Samples from biological tissues as well as artificial reservoirs, are frequently utilised for analysis in order to detect the presence of bacteria. These may be either normal flora, opportunistic pathogens or invasive microorganisms, from which analysis can deduce their role in disease states. The inaugural step in the process of bacterial identification is the…

can easily spread diseases around the world but alternate solution would be much better than reducing the level of human interaction. The other options available that can reduced the spread of global diseases is to develop an efficient and effective collaboration between all nations to work together…

INTRODUCTION Every organism plays an important role in our life. Just like plants, they have their own identity to help improve our way of living for today and for the future. In the field of medicine, plants can be utilized as sources of pharmaceutical substances. On the other hand, microorganisms occur almost everywhere in nature and affect the well-being of people in many ways. Different microbial species normally inhabit various parts of our bodies, such as the oral cavity, skin and…
