health of the soil‚ organic farmers rotate their crops (Alvarez). Instead of using pesticides or insecticides‚ organic farmers use helpful birds‚ insects‚ and organic fungicides to decrease disease and pests. Organic fungicides such as Bacillus subtilis‚ Bacillus pumilus‚ and Trichoderma harzianum are effectively used to prevent diseases that affect the roots (Murray). Conventional farmers use pesticides to protect the crops from disease‚ mold‚ and insects. Chemical fertilizers are used in conventional

Life on earth could not exist without bacteria because bacteria make possible many of the essential functions of ecosystems‚ including the production of antibiotics. Soil bacteria can be rod (bacilli)‚ cocci (spherical)‚ spirilla (spirals)‚ of these bacillus are more numerous than the others. Secondary metabolites are organic compounds derived from the modification of primary metabolite synthases of bacteria. They do not play a role in growth‚ development‚ and reproduction like primary metabolites do

The main evil ones are Staph Aureus‚ E. coli enteritis‚ salmonella‚ shigella‚ campy lobacter‚ cholera‚ botulism‚ listeria‚ bacillus cereus and yersina (gee‚ funny names!). Kids (like me) and the elderly‚ (like Mr. Bark)‚ and people with diabetes‚ heart disorders or kidney disease‚ have a much higher chance of having deadly symptoms from bacteria in our food.

F.tularensis‚ the causative agent of tularemia‚ is a small‚ aerobic nonmotile‚ gram-negative cocco-bacillus. Tularemia also known as rabbit fever and deer fly fever is a zoonotic disease that humans typically acquire after skin or mucous membrane contact with tissues or body fluids of infected animals‚ or from bites of infected ticks (Pal‚2007). Tularemia was recognized in Japan in the early 1800’s and in Russia in 1926. Tularemia as a biological weapon is the difficulty in culturing and growing

Becca Harris Writing 101 Position Paper Eliminating Genetically Modified Food at PLU What comes to mind when reading the words genetic modification or Bacillus thurigiensis (abbreviated Bt)? I envision laboratories and science experiments‚ when in reality these words are related to the food we eat every day. What most Americans do not know is the threat that genetically modified food presents to our communities. PLU should do everything in its power to ensure that its students and faculty

DIPTHERIA Diphtheria is an infectious disease caused by the bacterium corynebacterium diphtheria. This disease affects the mucous membranes of the respiratory tract and can also affect the skin (cutaneous diphtheria)‚ including the lining tissues in the ear‚ eye‚ and genital areas. Diphtheria was discovered in the 1880s‚ it was the leading cause of children’s death in many parts of the world‚ it was also known as “The Strangling Angel of Children”. Although diphtheria affects younger children
