The composition of the aerobic human vaginal microfloras has been extensively studied . These floras are dominated by lactobacilli; however, other aerobic bacteria may also be present, including Staphylococcus aureus. The bacterial density of S. aureus changes dramatically during menstruation, increasing logarithmically in the vagina compared to during nonmenses . A major end product of Lactobacillus metabolism, lactic acid, is responsible for maintaining the vaginal pH at approximately 4 at times other than menstruation. During menstruation, lactobacilli appear to be unable to maintain vaginal pH, and the rise in pH corresponds with rises in S. aureus levels.

How can heavy growth of staphylococcus aureus be treated?
There are several ways that heavy growth of staphylococcus aureus can be treated. Some medicines used are methicillin, nafcillin, oxacillin, cloxacillin, dicloxacillin, and flucloxacillin.
Does Staphylococcus grow on non crystal violet MacConkey agar?
Staphylococcus will not grow on Mac since crystal violet inhibits the growth of Gram positivesfmchinea: Actually some species of staphylococcus grow on MacConkey's plate including Staphylococcus aureus.
Is staphylococcus aureus a psychrophile?
yes its a mesophile with growth optimum around 20 to 45oC a minimum of 15 to 20oC and a maximum of about 45oC or lower.
Will s aureus grow on a crystal violet agar plate?
Yes. S. aureus can grow on TSA plate because this plate is general purpose medium and has most nutrient for bacteria growth.
What is human werewolf disease Andwhat are its symptoms?
Hypertrichosis is a condition that causes excessive hair growth over the entire body and has been linked to the belief in werewolves in less enlightened times.

What has the author Rachael Buck written?
Rachael Buck has written: 'The effect of wound dressings on growth and exotoxin production by Staphylococcus Aureus'
How does staph infections spread?
Staphylococcal can be produced in improperly stored food and therefore cause food poisoning. Staphylococcus aureus can survive on dry surfaces making transmission chances higher. During the 1980s tampons allowed the rapid growth of S. aureus which released toxins that were absorbed into the bloodsteam.
What the purpose of mannitol salt?
The purpose is to select for salt-tolerant microbes. Most species of microbes can't grow in such a salty environment. The only genus that can culture on an MSA plate is Staphylococcus. The only species of Staphylococcus that can ferment Mannitol is Staph. Aureus. If the plate turns yellow, you know that Mannitol was fermented into an acid, which only Staph. Aureus can do. If there is a little growth (aka the culture is red) then it's still most likely a species of Staph such as Staph. epidermidis. If there is no growth, as in E. coli, then there will be no culture and no change in color.
How to isolate staphylococcus aureus from freshmeat?
You could run the meat through a blender, strain out the juice, filter that with something along the lines of a 2 um filter then plate 100 ul aliquots on mannitol salt agar plates, incubate at 37C for 24 hours. If there is growth you have a Staphylococcus, if the media turns yellow you have a S. aureus. (That's how I'd approach it without looking anything up specifically in a food microbiology reference.)
Why is an overabundance of nutrients harmful to a water supply?
It causes excessive aquatic plant growth.
Is staphylococcus aureus a psychrophile?
yes its a mesophile with growth optimum around 20 to 45oC a minimum of 15 to 20oC and a maximum of about 45oC or lower.
What is the genetic disorder that causes excessive hair growth?
Hypertrichosis very rare disorder also called werewolf syndrome.
Is Psoriasis an excessive rate of epithelial cell growth is?
Yes, Psoriasis is an excessive rate of epithelial cell growth.
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.
What does too many nutrients in a marine tank do?
Excess of nutrients causes eutrophication i.e. excessive growth of algae take place leading to oxygen deficiency.
