ASSIGNMENT HELP | Find one example of a genetically modified bacterium used to benefit humans.

When you think of genetically modified organisms (GMOs), it is common to think of genetically modified foods. Battles rage in the media and political circles regarding the safety and efficacy of genetically modified crops. However, there are many other applications for genetic modification, and microbiology is full of examples. Many bacterial species are products of genetic modification as well. Science has the ability to manipulate the simple genome of bacteria to produce many products that are beneficial to humans.

Discussion questions:

1. Find one example of a genetically modified bacterium used to benefit humans. Provide the genus and species, and briefly discuss the primary uses. You may use one of the examples above or find your own example, but the organism must be genetically engineered or altered.

2. Is it ethical to use genetically modified bacteria? Why or why not?

3. When a new organism is created in a lab, the scientist responsible for the discovery can patent the new organism. What ethical concerns surround the idea of owning the patent on a living organism?


Genetically Modified Organisms (GMOs)

            Beneficial bacteria found in the human gut have been subjected to extensive genetic | PLACE YOUR ORDER NOW AT | ccording to Cummins and Ho (2005), probiotic bacteria modulate the immune system and provide an ecological balance in the human gut, which excludes disease-causing | PLACE YOUR ORDER NOW AT | modified bacterium | PLACE YOUR ORDER NOW AT | uses of L. acidophilus include treating lactose intolerance, vaginal yeast infections, Crohn’s disease, and overgrowth of bacteria found in human intestines (Cummins & Ho, 2005).

           Because modification of the genetic makeup of organisms can be done, does it mean we should? And is it ethical?
