I. Introduction
In society, bacteria are closely monitored. One of the most common groups of scrutinized bacteria is gram-positive cocci. This type of bacteria is the predominant group that is found on skin. Some of these species include, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, and Streptococcus pyogenes. Normally these bacteria are harmless, but when given a nutritious competitive free environment, they can be dangerous; especially in patients that are immunocompromised. These species of bacteria have begun to acquire antibiotic resistances; for example the first vancomycin-resistant were reported in Europe in 1988 (Courvalin 2006). This combination opens the door for a superinfection. Superinfections can be caused by an antibiotic killing off most of the bacteria followed by the survivors repopulating the area unhindered. A superinfection can be tough to get rid of especially in the immunocompromised patients mentioned before. Some of these patients are infected in the hospital setting. This type of infection is known as a nosocomial infection. Gram positive cocci can be accounted for over half of the blood stream infections of the U.S., Canada, Europe, and Latin America (Pfaller et …show more content…
Discussion and Conclusion
The unknown had results that lined up exactly with the organism S. epidermidis. In conclusion one could determine that tube #36 contained the organism S. epidermidis. The best test to look at was the tellurite glycine plate. The unknown and the S. epidermidis were similar in appearance and in growth pattern. The other tests confirmed the assumption of S. epidermidis.
S. epidermidis is normally found on the human skin and is considered normal flora. This microorganism is a popular nosocomial infection due to its abundance on human skin. Sterile instruments normally infect the patient with the penetration through the skin. Thanks to this issue it is hard to totally prevent infection by S.

C. pneumonia and S. aureus will be used for each step in this study. A gram stain, a Staphylococcus selective growth test, and a resistance test will be done in this study. Four subjects were cultured using cotton tipped applicators. The auxillae were cleaned of any deodorants and allowed to rest for 10 hours. The cotton tipped applicators were vigorously rubbed against the epidermis of the auxillae. Each sample was then gram stained along with the control. One agar plate each of Mannitol salt agar…
