Conclusion Unknown 10 is Staphylococcus xylosus. The genus Staphylococcus consist of bacteria that are known to cause most surgical and skin infections, respiratory disease, and food poisoning (5). It was first discovered by a surgeon named Alexander Ogston, who noticed a surgical abscess in a knee joint (5). He described the genus as having a grape bunch appearance. The genus name is derived from the Greek root staphyle meaning bunch of grapes, and kokkos meaning berry (5). Most Staphylococcus species are primarily found colonizing the epidermis of human skin, because of this they are becoming an issue in the medical field by causing many infections in humans when given the opportunity (6,7). Staphylococci commonly infect hospital patients.
Unknown #462. Multiple tests were performed as described in Brown’s1 manual to identify the unknown; it was determined that the unknown was Staphylococcus epidermidis. The incubation temperature of each test was 37˚C and they were incubated for 24-48 hours. The morphological test performed on the unknown #462 were all consistent with the expected results for this bacterial species such cell shape, motility, and gram stain. The bacterium was gram positive was confirmed by growth on PEA plate, inhibition of growth on EMB plate, and through gram staining. The optimal growth temperature was at 37˚C which corresponds to the optimal temperature mesophilic bacterium as stated in StrainInfo2.
Last january, I caught a disease called strep throat. I felt terrible and just wanted to sleep. I went to the doctor. She gave me some medicine. The doctor gave me a strep test and it was positive. At first, my throat felt sore and itchy. Strep throat is very contajus, so I got to stay home for a few days. After a week, my throat cleared up and I felt much better. It was great to feel healthy again.
He found that pus filled cysts had formed, but the cysts did not appear when he treated the pus prior to injection. Later in 1884, a German surgeon named Anton J. Rosenbach later coined the name for the bacteria, Staphylococcus aureus (Orenstein, n.d.).
Staph are common bacteria that are denizens of the human body. It is perfectly fine to carry staph; a lot of healthy people hold it within their bodies without being infected by it. Furthermore, one third of the population has staph bacteria in their noses. However, staph can rapidly become quite a problem if it manages to enter the body, usually through a cut, and cause an infection. Staph is one of the most popular causes of skin infections in the U.S. Most infections are minor, not fatal, and don’t require special treatment, but some can be disastrously life-threatening, creating festering wounds or pneumonia.
When reflecting back to experiment 3, Aseptic Technique and Culturing Microbes, I realized the large amount of microorganisms that can be found in everyday life. Many different types are found with in the human body. Theses experiments focused on two types of bacteria. First was Staphylococcus epidermidis, found on the skin, and second was Lactobacillus acidophilus, found in the gastrointestinal tract. Both have similar needs for growth when it comes to temperature, however, different growth environments are used.
Staphylococcus aureus is the leading cause of skin and soft tissue infections, it can cause serious infections such as bloodstream infection, pneumonia or bone infections. Though it can cause infections it is part of the normal human flora it is mostly found on the skin or in nasal cavities. It is a facultative anaerobic gram positive cocci, it is usually in pairs or clusters. The bacterium is also catalase positive, oxidase
The symptoms of streptococcus pyogenes have been recorded by scientists and historian for many years. Hippocrates (known as the father of medicine), was the first to records symptoms of scarlet fever and “the flesh-eating bacteria; two infections that group A Strep are now known to be involved in. Pasteur was the first to isolate the chain-forming bacteria and Rosenbach named it.
What are these other serious illnesses that are caused by group A Streptococcus? What is group A Streptococcus? Group A streptococci are bacteria commonly found in the throat and on the skin. The vast majority of GAS infections are relatively mild illnesses, such as strep throat and impetigo. Occasionally, however, these bacteria can cause much more severe and even life threatening diseases such as necrotizing fasciitis (occasionally described as "the flesh-eating bacteria") and streptococcal toxic shock syndrome (STSS). In addition, people may carry group A streptococci in the throat or on the skin and have no symptoms of disease.
Staphylococcus aureus is a microorganism that appears on several diverse surfaces. This bacterium lives harmlessly on the skin as part of the normal flora. Hard surfaces are also covered in S. aureus. The microorganism is gram positive.

The online article discusses the spread of diseases amongst students in close quarters with relation to a recent study on staph infections. General demographics give examples of how a disease such as staph can spread between students rapidly in their limited environment. A specific study on staph resistant to medicine references statistical data that implies real-life scenarios. Powers elaborates on the idea that staph infections on campuses are not a major concern, but a concern nonetheless as long as students live in a communal setting. The author implies at the end of the article that the most precedent concern with staph infections lay in better upkeep of hygiene facilities used by students as students in these environments are completely
Commonly referred to as strep bacteria.” (Streptococci and streptococcal Infections). Streptococci are normal bacterial residents on the skin and mucous surfaces outside or inside humans. Streptococcus contains a variety of species some of which cause disease in humans and other animals.
aerogenes) is a microorganism commonly found in soil and is an example of an opportunistic pathogen; which means they are disease causing organisms. (E. aerogenes) is also associated with exposure in nosocomial settings like hospitals (Rogers, 2017). Neisseria sicca (N. sicca) mainly colonize in human oral cavities and in the nasopharynx, most are nonpathogenic and are found in the normal microflora of the human body (Neisseria, 2015). Staphylococcus aureus (S. aureus) is a type of bacteria that roughly 30 percent of people carry in their nose (Healthcare-associated Infections, 2011).
Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact. Colonies of S. aureus appear in pairs, chains, or clusters. S. aureus is not an organism that is contained to one region of the world and is a universal health concern, specifically in the food handling industries.
Though, it’s tendency to be pathogenic varies with the person. It is usually pathogenic primarily to those susceptible to infections. Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Staphylococcus haemolyticus, and Staphylococcus hominis can be treated with antibiotics such as penicillin. Nonetheless, they can develop resistance to the penicillin derivatives as well. Each species of “staph” can work together to cause similar infections because they are all a part of the body’s natural
