Tuberculosis Tuberculosis (TB)‚ also known as consumption‚ is an infectious disease caused by the bacterium Mycobacterium tuberculosis (MTB). TB is the leading cause of death in the world among reported deaths caused by a bacterial infectious disease. The disease affects 1.8 billion people per year‚ which is equal to one-third of the entire world population (Todar). Pulmonary tuberculosis accounts for the majority of the TB cases in the United States (Todar). Bovine tuberculosis is another infectious

This is also called herbicide resistance mainly to glyphosate and glufosinate ammonium introduced in soya‚ oil seed rape (canola)‚ cotton‚ maize and sugar beet (Pretty‚ J) and it is achieve through the introduction of gene from bacterium usually Bacillus thuringiensis (Bt) that expresses for the herbicide resistance. This allows the producer to apply any broad spectrum herbicide to the crop field to kill weeds without destroying the crop. It allows the farmer to reduce weed pressure off the crop

however; they found that consumers would not eat the food as it was a health hazard. Also it had harmed the environment as the pesticide would poison the water supply. By having genetically modifying crops food can be protected from insects and pests. Bacillus thuringiensis(BT) Corn is an example of a genetically modified crop‚ which contains delta endotoxins and when insects are exposed to this the toxins will paralyse the insect’s digestive system and kill it. Hence GM foods can be very beneficial as

He discovered the causative agent for this disease as Bacillus anthracis. Koch discovered spore-formation in the anthrax bacteria‚ which could remain dormant under specific conditions. However‚ under optimal conditions‚ he found that the spores were activated and caused disease. To determine this causative

common prevention methods include‚ controlling time and temperature‚ preventing cross contamination‚ practicing personal hygiene‚ and purchasing from a reputable supplier. Controlling time and temperature can prevent many bacteria but most commonly Bacillus cereus and listeria. Preventing cross contamination is the best way to prevent Salmonella. Practicing personal hygiene can prevent Shigella and Staphylococcus. There are many different ways to cook meats; one method that many professional

Cocci – oval or spherical shaped. Bacillus – are rod shaped. Spirillum – are thick‚ rigid spirals. Vibrio – are curved or a comma shaped rod. D. What are the common arrangements of bacteria? Diplo – oval shaped‚ found in pairs. Strepto – are cocci that arange into chains. Staphylo
