blessing. GM food is crops modified to enhance desired traits‚ and promises to meet the demand for food for this booming population in the near future. GM food allows modified crops to be pest-resistant‚ herbicide-tolerant‚ disease-resistant‚ cold-tolerant and drought-tolerant or salinity-tolerant. Pest-resistant crops prevent farmers from incurring huge losses from insect pests. This trait also allows non-usage of chemical pesticides‚ which are typically used in tons annually‚ and therefore no longer

Section 1: Infections in Healthcare Settings Essay. Nosocomial infections‚ hospital acquired infections‚ are an on-going concern to healthcare professionals. These infections are one of the major causes of death in hospitalised patients and are a significant burden on not only the patient’s and the public’s health (as organisms causing nosocomial infections can be transmitted to the community through discharged patients‚ staff and visitors) but also the economy. A nosocomial infection is an infection

independent and EU investigations showed no evidence of ill health effects in humans under normal conditions. Herbicide is designed to kill plants not people. If herbicide doesn’t hurt people‚ do the crops that produce insecticides hurt people? Insect resistant or Bt crops produce a groups of protoxins known as the cry protoxins or Bt toxins. The Bt toxins have insecticidal effects on pests attempting to eat the crops. The toxins have been proven to be nontoxic in humans and other nontarget species both

the overuse of antibiotics while the second is due to the fact that “bacteria naturally develop resistance to antimicrobial drugs.” (Clemmitt‚ 2007) One example of a “super bug” is the ever so popularly known- MRSA. MRSA stands for methicillin resistant staphylococcus aureus. (cdc.gov‚ 2007 as cited by Clemmitt‚ 2007) MRSA has two different kinds- CA-MRSA is community acquired MRSA and HA-MRSA which is hospital acquired MRSA. (Clemmitt‚ 2007) To reduce the risk of creating “super bugs” the doctors

------------------------------------------------- Genetically modified crops Genetically modified crops (GM crops‚ or biotech crops) are plants‚ the DNA of which has been modified using genetic engineeringtechniques‚ to resist pests and agents causing harm to plants and to improve the growth of these plants to assist in farmers efficiency. Genetic engineering techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create

Superbugs are becoming a big problem in the world‚ but what are superbugs? Superbugs is a bacteria that becomes resistant to antibiotic drugs they carry genes that are resistant to antibiotic drugs and cannot stop the bacteria from multiplying (Staff 1). You might know of superbugs by the term multidrug-resistant bacteria. This mostly happens when people overuse antibiotics and their body becomes immune to those drugs. In very severe cases people with extremely weak immune systems usually die if

Enterococcus faecalis is resistant to most commonly used antibiotics like cephalosporins and aminoglycosides‚ and a new study suggests that its becoming more resistant to vancomysin. Treatment for an infection by Enterococcus faecalis would be amoxicillin if the organism is susteptible. Treatment for Enterococcus faecalis that is resistant would consist of taking linezolid and daptomycin. The results from the gram positive enterics included: Taxo P (optichin) Resistant to Optichin Bile Esculin
