Why is it important to differentiate S aureas from S epidermis or S Saprophyticus?
Wiki User
∙ 9y ago
In terms of microbiology, S. aureus and S. epi can be differentiated through a number of metabolic tests. The tests being Methyl Red, Vogues-Prauskauer, Mannitol fermentation (of which S. aureus would be + and S. epi - ) and Oxidase (S. aureus - and S. epi + ).

What is the common bacteria in the wounds?
This depends on the location of the wound.The most common bacteria contaminating skin wounds are Staphylococcus aureas and Streptococcus pyogenes, although if they are near the anus, gram negative bacteria such as Escherichia coli are much more common. Anaerobes are also common in wounds near the anus.Classically, wounds in the feet are contaminated with anaerobes, or Pseudomonas aeruginosa if it is a wound through the sole of a shoe. Dirty lacerations, or lacerations with large areas of tissue destruction are at high risk for Clostridium tetaniproliferation, hence the reason you get your tetanus booster when you get cut. Animal bites, such as cats and dogs, are at high risk of Pasteurella multocida infection, which can cause a rapidly progressive cellulitis, while human bites can cause some very nasty infections with the classic organism being Eikenella corrodens.Again, I can't reinforce how important the location of the wound and the situation in which the wound was inflicted are in proper treatment. Most cases require only irrigation and possibly a topical antiseptic or antibiotic. Some high risk cases, however, demand empiric antibiotics to prevent infection.
Where do harmful bacteria usually live?
Harmful bacteria are bacteria capable of causing disease or injury to humans. We are surrounded every day by millions of bacteria, viruses, and other microorganisms, and many of them can become harmful under the right circumstances. Illness is a complex interplay between the host (you), the bacteria, and the environment. A change in any of these factors can result in disease. For instance, (arguably) the most famous bacteria in the world, Staphylococcus aureas, lives everywhere, but is typically found on your skin. Predisposed hosts (those with immune system diseases, immunosuppression, or problems with the body's most fantastic antibacterial shield - the skin) may become infected with this bacteria that everyone in the world has all over them by the millions. The real problem is finding out why some people are more susceptible to infection, because there really is nothing we can do about being exposed to these organisms. There are many more of them than there are of us.
Does staphylococcus aureus have an infect on the human body?
Staphylococcus aureus is a bacterium that is usually found on the skin at any given time. Staph is harmless unless it is colonized. Colonization occurs when the bacteria enters the body and begins to replicate itself. Once colonization occurs, staph seemingly takes on a life of its own and begins feeding on the body. Staph infections then take on the role as a parasite; needing to feed on its host to stay alive. If left untreated, staph can grow exponentially. Staph colonies usually stay together unless the nutrients in its host are depleted. The dangerous aspect of staph, is when it colonizes other parts of the body. In these cases, staph can attach itself to major organs causing havoc in the host's body, possibly leading to death of its host.
Is E coli larger than Stapylococcus aureas?
is E.coli larger than stapylococcus aureas
Does staph aureas hate antibiotics?
if it had feelings, then yes. coz coz antibiotics kill it.
How long can staph aureas stay dormant inside our body?
S. aureus can lay dormant in the body for years undetected. Once symptoms begin to show, the host is contagious for another two weeks, and the overall illness lasts a few weeks. If untreated, though, the disease can be deadly
What is the second part of the scientific name?
The species is the second word in a binomial name, written in lowercase. The Genus is the first word/name and the first letter is capitalized.
Normal flora of the human eye?
normal flora of human eye is generally found on the conjunctiva(the mucus membrane) the number of colonies are usually small due the presence of mechanical action and biochemical action of tears (which consist of lysozyme) Staphylococcus epidermidis and coryneforms are generally dominant neisseria spp and aureas spp are sparse
What is the motto of Willowfield School?
Wellesley College's motto is 'Non Ministrari sed Ministrare'.
Is staph infection and MRSA the same thing?
Yes and no. MRSA is a specific type of staph infection - MRSA is an acronym for Methicillin resisant Staphylococcus aureas. It denotes that the specific Staph organism has developed resistance to an antibiotic which is commonly used to treat skin and soft tissue infections. Because of this resistance, MRSA infections are harder to treat. For some reason, MRSA organisms are also frequently more virulent, meaning they cause worse infections. Currently, there are two different types of MRSA, hospital acquired and community acquired. These are denoted as HA-MRSA and CA-MRSA. HA-MRSA are more frequently the more virulent variety and are resistant to more antibiotics, while the CA-MRSA organisms are easier to treat and usually cause only boils and folliculitides, rather than systemic infections and pneumonias, like the HA-MRSA. MSSA, methicillin sensitive Staph aureas, is still the most common form of staph infection in most parts of the U.S. and can be treated pretty easily with many different types of antibiotics.

Why does the medical profession think that the overuse of antibiotics is bad for society?
We don't think that - we know it. Two quick reasons. First, no medication is without side effects or risks. Everyone has the potential to be allergic to any medication he is given. Antibiotics, in particular, also have the potential side effect of a very dangerous form of diarrhea developing, called pseudomembranous colitis. This disease has seen a rapid rise in the past year, some cases causing people to have their entire colons removed, and even death. There are some very serious risks involved with antibiotics. Second, too liberal antibiotic use has led to the development of resistant strains. I'm sure you have read or seen stories on the television about MRSA, or methicillin resistant Staphylococcus aureas. This is a bacteria that used to be exquisitely sensitive to a certain type of penicillin, called methicillin. Because of antibiotic overuse, many of these methicillin resistant strains are popping up, and they seem to be more virulent, meaning they are more likely to cause infection, and the infection they cause tends to be worse. Many many other bacteria have the same story because of overuse of antibiotics. As you see, with my two little examples, antibiotic overuse is very bad. Soon, there may be bacteria we cannot treat at all with antibiotics, unless new antibiotics are invented, which is a very time consuming and expensive task.
