Plant pathogens and diseases

discovered? How many are estimated to exist? Scientists have discovered 10 000 prokaryotic species but estimate that about 90 000 more exist. What is a pathogen? Are all bacteria pathogenic? List some examples of bacterial diseases. A pathogen is a bacteria or virus which causes disease, but not all bacteria are pathogenic.…

have had to be tested and met certain requirements before the government deemed it safe to drink. In Cape Town water is stored and collected all over the Cape. They are stored at a dam,river or reservoir. Then the water will be taken to a treatment plant where the water will be purified and then…

where one specific plant is grown in a specific area because society depends on it. GMOs revolves around the idea of producing crops that have all the same desired and beneficial traits. As history shows lack of genetic diversity can destroy both the crop and society if the society greatly depended on this crop. In the article Endangered animals can be identified by rate of genetic diversity loss “"Genetic diversity is a key component to the long-term…

Results Primer design and LAMP reaction Among 40 different primers (OPA 1-20 & OPB 1-20 series) screened by RAPD PCR for differentiating the Mycosphaerella eumusae from other leaf spot causing fungal pathogens in banana, only the primer OPB 10 has generated a unique amplicon specific to M. eumusae at 1300 bp size. A total of nine different sets of LAMP primers were designed based on this specific SCAR derived RAPD marker sequence of M. eumusae and screened for the production of LAMP products…

means? The immune system is the one of necessity system in the body. It helps the body defend against every foreign body that causes disease for body. The immune system is getting stronger and stronger while it destroys disease. It takes experience from disease which it is destroyed. The immune system is defined as “the system that protects your body from diseases and infections” in Merriam-Webster dictionary. In other words, the immune system safeguards the body from illness and discovers every…

(2015) Novel Strategies To Enhance Lateral Flow Immunoassay Sensitivity for Detecting Foodborne Pathogens. Journal of Agricultural and Food Chemistry. 63, 745−753. DOI: 10.1021/jf5046415. This article talks about the simplicity, stability and sensitivity of conventional lateral flow immunoassay (LFI) device for the use of detecting foodborne pathogens. Foodborne pathogen has prevailed to cause disease and even death in individuals that has been exposed to bacteria thru food consumption.…

kill all the pathogens. • While preparing meat we must keep it away from other eatables. • We must wash the knife and cutting board after cutting the meat • Do not rinse the meat too much so it could lost its essential nutrients. • While cooking meat it must be care that meat should not have red juices • Meat is always cooked…

Urban development in Apia Introduction Apia is the capital city of Samoa and the largest city in the Pacific. In Apia, there is a trend that 40% of population are looking forward to live in urban area. And the rate of urban growth will be continued to increase (Pacific island populations in Jones article, 2001). Urban population, density of house and waste from industries are all rise continually. Due to the increasing of pressure of urbanization and the lack of effective management solutions,…

elevation, slope, terrain, bodies of water, etc. This topography can play a huge role for plants. For example, a steep slope is susceptible of rapid surface runoff and soil erosion which can cause soil degradation and have a serious impact on the efficacy of crop production. As well, the elevation of land can play a huge role in the agricultural system. Many people don’t know that the altitude of the terrain influences plant growth and development primarily through temperature effect. It has…

Medicine in Africa Long before the introduction of cosmopolitan medicine, diseases existed and ancient people had their ways of dealing with them. Traditional medicine, dominated the ancient world with different societies embracing different methods of eliminating or reducing the impacts of the prevailing diseases. According to WHO, Traditional medicine refers to the entire knowledge and skills as well as practices that ancient people applied to curb the negative impacts associated with…
