The subjects that will be discussed are staphylococci, Unknown 1, and Streptococci & Enterococci. Exercise 26 emphases on Staphylococcus. Staph is short for staphylococcus, which is a type of bacteria. The genus for staphylococcus is staphylococci there are various types but the most important organisms within this genus are Staphylococcus aureus, Staphylococcus saphrophyticus, and Staphylococcus epidermidis. S.aureus is the common bacteria within this genus and is the number one infection in U.S. Hospital. Staphylococcus saphrophyticus is the leading cause for urinary tract infections & Staphylococcus epidermidis is part of the normal microbiota in the skin of the nasal passage that can cause infectious disease from time to time. These microorganisms

aureus, S. saphyophyticus, and S. epidermidis all have a similar microscopic appearance, which are gram positive, coccus irregular clusters of bacteria. Additionally, Exercise 27 focuses on an unknown bacterium. Since numerous kinds of microorganisms cultivate in and on the human body as normal microbiota, proper identification is required. Identifying unknown bacteria is part of an important aspect in microbiology. In order to properly identify the unknown bacterium following procedures is required which can be found in Material & Methods. Moreover, Exercise 28 focuses on Streptococci and Enterococci. The genus of streptococcus is streptococci and the genus for enterococcus is enterococci. The organisms most important in the group are streptococcus pyogenes, streptococcus pneumonia and Enterococcus faecalis. Streptococcus pyogenes is a common bacterium that causes strep throat, scarlet fever and skin infections. It is a Gram-postive, non-motile, non-sporeforming coccus that occurs in chains or in pairs of cells (Todar, 2012). Streptococcus pneumonia causes various types of illnesses including pneumonia, ear infections, sinus infections, menigitsis and bacteremia (CDC, 2015). Enterococcus faecalis is part of the microbiota of the colon but can cause nosocomial
