Bacterial Diveristy

Bacterial diversity and the evolution of antibiotic resistance is an amazing topic in the field of biology. Bacteria are some of the most minuscule living organisms on our planet, yet some yield the power to sicken or even kill an organism as large and complex as humans. Other bacteria are essential to our survival. Bacteria are practically capable of living in every environment on the planet. They live in, on, and around each and every human. Their short lives and fast mutation rates create interesting problems for scientists trying to study them. Bacteria have a fast reproduction rates, and the ability the pass genetic information very quickly through plastids.

Our interaction with bacteria in the form of antibiotics creates a whole new realm of problems. Antibiotics are substances that fight infections caused by bacteria. Because of bacteria’s fast rate of evolutionary change, they are very well at creating an antibiotic resistance, which is the ability of bacteri

Our human interaction with bacteria in the form of antibiotics creates a whole new realm of problems. Because of bacteria’s fast rate of evolutionary change, they are very well at creating an antibiotic resistance to specific antibiotics. After a bacterium becomes resistant to multiple antibiotics, there is little we can do to combat it, which may lead to serious or even fatal infections. Bacteria that are harmless to one individual may be life threatening to another with an immune system deficiency. We used ampicillin as the antibiotic in our experiment. It is clear to see that many colonies grew when there was very little ampicillin present. This shows that they can tolerate mild antibiotics. The stronger the dosage, the fewer colonies there were present in the treated zone. Stronger dosages of antibiotic must be present to successfully kill bacteria. This makes antibiotics for humans a bit tricky. Once a person is taking an antibiotic for a long period of time, they will build up a resistance to it, and must be treated differently.

We found that the light switches in the Biology lab had far more bacteria than the trash can. I personally found this disturbing. The light switch had 5 times as many colonies as did the rim of the trash can. So many people come in contact with the light switches everyday, that cannot be healthy. Conclusively, I was very surprised and disappointed at the results of our experiment.
