Zachary Newton Biology 1520 Lab P9 Joey Bear Lab Report 1 Introduction: The experiment that was conducted involved the comparison of growths of E. coli and Staphylococcus aureus cultures when exposed to UV over various lengths of time. E. coli is a very common bacteria that can be found in the lower intestine of most warm blooded animals. This bacteria is a part of the normal flora of these intestine and are virtually harmless to the host. Usually, the E. coli is beneficial to the host and aids in the digestion of food and the warding off of harmful pathogens. There are, however, a few strains of E. coli that can be dangerous to humans. Such strains are usually found in food products that are found to host an outbreak. These packaged foods usually include meat that is ingested. Once ingested, the strain causes food poisoning and in some cases can be fatal to the person infected with the harmful bacteria. Not only are certain strains dangerous to humans but they also are very difficult to treat. As Gram-negative organisms, E. coli are very resistant to many antibiotics that may normally be used to treat bacterial infections (Escherichia Coli). Despite its harmless relatives, the few dangerous strains of E. coli are a huge threat to many professional fields that deal with contact with the human body. Staphylococcus aureus is becoming increasingly dangerous to humans, especially in the medical profession. The methicillin-resistant Staphylococcus aureus strain is becoming more rampant among hospitals and locker rooms than ever before. The reason this strain is so dangerous is the capabilities that the staph bacteria has attained. This strain has developed an extreme antibiotic resistance and is very difficult to treat. In hospitals, it often manifests itself in wounds and incisions made during surgeries. Research has also revealed that as time progresses, the strain seems to become more and more resistant to treatment. Once it finds a host, Staphylococcus aureus begins to attack the host with infections of the

blood, lungs, and sometimes it may even cause death. Another reason the bacteria is so effective is its ease of transfer from one host to another. Virtually any public surface can be used as a breeding ground for this bacteria (Jackson 2008). For these reasons, there needs to be proper sterilization techniques that can be easily utilized in situations that are prone to staph infection such as those found in medical facilities. Many techniques have been used in various fields of study to destroy both E. coli and
