Plant pathogens and diseases

Climate change may be partly to blame for the decreasing number of Atlantic salmon. Some direct biological impacts of the change in climate include physiological stress, increased depletion of energy reserves, increased susceptibility and exposure to disease and disruptions to breeding efforts there is evidence that the temperature of the sea's surface may affect the young salmons survival. It is also thought that climate change may affect salmon growth rates or make their food less available.…

for other organisms. Under 1% of bacteria on Earth cause disease, and the bacteria that do can usually be treated with antibiotics (“Bacterial Infections: Medline Plus,” par 1). The common image of bacteria is that they are all horrific organisms that cause disease. While people should most definitely wash their hands to avoid bacterial infections such as tuberculosis and mecticillin-resistant staphylococcus aureus (MRSA), these pathogens are only a minute percentage compared to the rest of the…

immature bees behind. Researchers and scientists are still searching for the main cause of this phenomenon and suspect that pesticides and several diseases are involved. There are many factors that contribute to the leading cause of CCD, but pesticides alone are extremely harmful to the bees’ health and their natural habitat. Diseases, such as the Varroa disease, are also destructive to the bee colonies.…

insemination in dairy cattle selective breeding enables the best bulls and cows are chose to improve the genetic make-up such as qualities - milk fat content and quantity of milk in the dairy cow population. This helps to prevent the spread of diseases that can result from normal sexual reproduction because AI is done using sterile procedures also the use of AI can minimize injury to the cattle population that caused by aggressive bulls during the mating process. The use of genomic selection…

combined role of water temperature, salinity and Vibrio count in the risk of WSSV infections in P. monodon in the Philippines. Salinity is an important factor which determines the survival of V. cholerae (Thomas et al., 2006), the newly emerging pathogen of P. monodon along the Cochin backwaters (Joseph et al.,, 2015a). Acute low salinity stress was found to affect the immunity of P. monodon and increased their susceptibility to WSSV (Joseph…

(“Listeriosis outbreak timeline”, 2009), the disease associated with infection by Listeria. This concern was disregarded until people in a nursing home fell ill and sandwich meat from the same place tested positive for the presence of Listeria monocytogenes (“Listeriosis outbreak timeline”, 2009). On August 12, 2008, the Canadian Food Inspection Agency launched an investigation of the Maple Leaf company and eventually all meat-products produced by Maple Leaf’s Toronto plant were recalled…

evolution and origin of antibiotic resistance and that of infectious deadly pathogens. This would save the aged and children who would otherwise succumb to microbial…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

The enemy of the people focuses on the relationship between dr stockman and his brother there conflict , however a more important issue of the pollution of the baths seems to take a back ground position. Just as in the play today 's society debate and unimaginably deny climate change , we deny the effects of humans and or negative impact on the planet, we are a destructive force of nature because we do not work as a group or one global conscience that regulates or waste and works to being more…

the inner mucus layer is recognized by innate immune cells termed dendritic cells. Dendritic cells contain pattern recognition receptors (PRRs) such as Toll-like receptors (TLRs) that recognize microbial associated molecular patterns (MAMPs). Both pathogen and commensal microbiota contain MAMPs such as peptidoglycans, lipopolysaccharides and flagella. Activation of TLRs sets off a signalling cascade of nuclear factor-kappa B (NF-kB) to initiates the production of cytokines that results in an…
