Staphylococci are gram-positive microorganisms, which inhabit the surfaces of a human body. This kind of a microbe is a constant inhabitant of a human body, because it is almost impossible to find a man without Staphylococcus aureus no matter if it is an infant or an old man.
These bacteria are resistant to sunshine and are not killed under the influence of direct sun rays during a long period of time. Moreover, they are not afraid of dry environment or freezing, and the majority of chemical substances including hydrogen peroxide. Finally, it stands the heating at the temperature 70 C above zero during one hour.
There are about thirty kinds of these microorganisms. However, not all of them have pathogenic peculiarities. Staphylococcus aureus has. It resides on the mucous surface of the nasopharynx, fauces, damaged skin surfaces, nose, vagina, axilla etc. Infections caused by this bacterium may be different: skin disorders such as cellulitis, furuncules, sty, piodermia, pneumonia, otitis, chronic tonsillitis, or more difficult diseases like meningitidis. Furthermore, if Staphylococcus aureus causes minor skin damages, it can be cured without antibiotics. But, if it gets into deeper structures, it strikes other organs, which leads to metastatic contagion. For instance, septicemia is a serious disease, which may lead to lethal end, despite medical treatment by antibiotics.
The most common environment for Staphylococcus aureus is a nose. Almost 20 percent of people live with this bacterium persistently. However, it becomes dangerous under certain circumstances. First of all, it is the state of the immune system. If a person is healthy, there is no need to do antibiotic therapy. But, several rules should be followed to reduce the risks of the infectious diseases caused by Staphylococcus aureus. People should take care of personal hygiene and keep their houses clean.
To sum up, it is necessary to bear in mind that Staphylococcus aureus is a pathogenic microorganism that lives on the surface of the human body. If the immune system of a man is weak, it starts to invade the human body and may cause infectious diseases, which may differ in the level of severity. Staphylococcus aureus can be identified in the laboratory studying the sputum, purulent material, urine or blood of a man. Treatment of infections caused by S.aureus depends on the severity of the disease and may not always include antibiotics. However, if the infection is serious, it is required to follow serious antibiotic treatment.
