Staphylococcus aureus: MRSA infection is caused by bacterial strains of antibiotic resistant aureus staphylococci.
Staphylococcus aureus is a bacterium commonly found in the human body; human skin and nasal cavity are the natural habitat of this bacterium. It is present in approximately one third of the population.
Staphylococcus does not cause infection unless it penetrates the body through the cut or any other kind of wound (eg, burns, tears, open fractures, etc.), and even then produces less infections found in the skin (in healthy and immune, competent).
According to the Center for Disease Control and Prevention, about 2% of the population is a healthy bearer of MRSA.
Staphylococcus aureus: Resistance to antibiotics
The major issue caused by MRSA infection is the difficulty in finding an appropriate antibiotic treatment due to bacterial resistance to antibiotics used to treat staphylococcal infections. MRSA is the result of antibiotic use over the years when there was no real need for them.
For example, antibiotics are prescribed against colds, flu and other viral infections that do not respond to these medications. Even when properly used and targeted, antibiotics contribute to bacterial resistance. This is due to the fact that the antibiotic does not destroy the entire population of bacteria, and those who survive quickly obtain resistance. New research seeks to eradicate bacteria by nanotechnology.
Staphylococcus aureus: Symptoms
Staph infections (including MRSA) usually have an attack that is characterized by a small red skin swelling such as a bark, furuncle or spider. They can easily be converted into deep and very painful abscesses that require drainage operation.
Most of the time, bacteria can remain attached to the skin, but there are cases when they attack the body and can cause serious infections of the joints, bones, wounds, heart valves, lungs, and blood.
Staphylococcus aureus: The main risk factors are:
Entering the hospital – MRSA remains a concern in hospitals due to the fact that it can at any time infect vulnerable or immunologically inadequate individuals;
Long-term living in nursing homes;
Living in overcrowded, crazy spaces;
Invasive medical devices – through intubation, catheterization, infusion, there is a risk of creating MRSA entering the body;
Train sports contacts.
