How many people carry the Staphylococcus aureus bacteria?
In 25-30% of people, this bacteria is present on the skin lining normal, uninfected nostrils.
How is it possible that some strains of staphylococcus aureus can be harmless but others can be deadly?
Staphylococcus aureus is a diverse group of bacteria, with some strains being part of the normal human microbiota and typically harmless, while others can be pathogenic. The virulence of certain strains is often due to specific genetic factors that enable them to produce toxins or evade the immune system. For example, methicillin-resistant Staphylococcus aureus (MRSA) has acquired resistance to antibiotics and can cause severe infections, while non-resistant strains may not pose a significant threat. This variability in pathogenicity highlights the complexity of bacterial interactions within the human body.
With staphylococcus aureus what is the primary reservoir?
In the medical community human skin is commonly considered the reservoir for S. aureus. More specifically, in the infection control community the most common place to find S. aureus and MRSA are the nares and perinium - that's the first place we sample for culture swabs. That being said, humans aren't the only reservoirs for S. aureus, it's also been found in herd animals.
How do you prevent Staphylococcus aureus?
You can't prevent Staph. aureus as it is a natural bacterial resident on most human skin. However you can prevent Staph. aureus from causing problems or ill health by keeping good hygiene standards and preventing the bacteria from getting into skin breaks, cuts etc. where it will then become an infection.
Is staphylococcus species pathogenic all the time?
No, Staphylococcus species are not pathogenic all the time. While certain species, particularly Staphylococcus aureus, can cause infections and diseases under certain conditions, many staphylococci are part of the normal human flora and coexist harmlessly on the skin and mucous membranes. Pathogenicity often depends on factors such as the host's immune status, the presence of wounds, and specific virulence factors of the bacteria.
What isStaphylococcus aureus?
Staphylococcus aureus is a bacterium that is a member of the Firmicutes, and is frequently found in the human respiratory tract and on the skin. Also known as a staph infection.
Does the human body carry staph?
Yes, various staphylococcus bacteria are often found on humans. For example, Staphylococcus aureus is a frequent inhabitant of the nose and skin.
Which type of infection of the human body can most likely be treated with an antibiotic?
The majority of infections can be treated with antibiotics, however, there are a few strains of antibiotic-resistent super bugs, such as MRSA (Methicillin Resistant Staphylococcus Aureus) and VRSA (Vancomycin Resistant Staphylococcus Aureus.)

What causes excessive growth of staphylococcus aureus?
Well, hello there! Excessive growth of Staphylococcus aureus can be caused by a variety of factors, such as poor hygiene, weakened immune system, or being in close contact with someone who has a staph infection. It's important to remember that these things happen, but with proper care and attention, we can create a healthier environment for ourselves and others. Just like painting a happy little tree, we can take small steps to prevent the excessive growth of Staphylococcus aureus.

What genus of bacteria causes more diseases in human than any other?
The genus of bacteria that causes more diseases in humans than any other is Staphylococcus, particularly Staphylococcus aureus. This bacterium is responsible for a wide range of infections, including skin infections, pneumonia, and bloodstream infections, as well as conditions like toxic shock syndrome. Its ability to develop resistance to antibiotics, such as methicillin-resistant Staphylococcus aureus (MRSA), further complicates treatment and increases its impact on public health.
Is staphylococcus species pathogenic all the time?
No, Staphylococcus species are not pathogenic all the time. While certain species, particularly Staphylococcus aureus, can cause infections and diseases under certain conditions, many staphylococci are part of the normal human flora and coexist harmlessly on the skin and mucous membranes.

What is the kingdom called of human beings?
Human beings are in the animal kingdom, as far as classification goes.
