The world around us is inhabited by a huge number of various microorganisms: bacteria, viruses, fungi. Many of them peacefully coexist with a person, without exerting any negative influence on his body.
But there are those who, under certain conditions, pose a significant threat to health. Staphylococcus aureus can safely be counted among these bacteria.
What is Staphylococcus aureus?
Staphylococcus aureus only exists near the person, but is often part of its natural microflora. This bacterium is called opportunistic, as it can exist on the skin, in the intestines, mucous membranes of the nasopharynx and genital organs of a person, without causing any diseases. Of course, provided that his body has a healthy immunity.
Staphylococcus aureus bacterium able to survive in the most severe conditions. It is resistant to ultraviolet radiation, high and low temperatures, and many disinfectants. Even freezing is not able to destroy this bacterium. It can live in a salty environment for a long time and even can destroy hydrogen peroxide molecules!
Despite the fact that Staphylococcus aureus is a bacterium about which scientists have sufficiently complete information, fight it is extremely difficult. It mutates easily, adapting to any antibiotics. Sometimes drug treatment makes the bacterium even more resistant, the human body does not develop immunity to it, and reinfection Staphylococcus aureus may be even more difficult.
How does Staphylococcus aureus manifest?
The bacterium Staphylococcus aureus can cause two types of diseases.
- Intoxication.Toxins are formed inside the body when bacteria enter the Staphylococcus aureus, for example, in the intestines. The symptoms of this disease are similar to the symptoms of severe food poisoning: severe abdominal pain, diarrhea, vomiting.
- Infection.Staphylococcus aureus bacteria, penetrating human blood or tissues, can cause their destruction. This is usually accompanied by a local or systemic inflammatory response. Especially dangerous is the ingress of bacteria into the blood. In this case, it is able to get to any internal organ, including the brain, causing extremely complex inflammatory processes.
Given that Staphylococcus aureus diseases are difficult to treat and can have extremely negative consequences, the best means of dealing with them - prophylaxis. Oddly enough, but to protect against staph bacteria most often enough to maintain a healthy immune system and follow the rules of hygiene.
Staphylococcus aureus: how is it transmitted?
- There are many ways to transmit Staphylococcus aureus. Especially often they are infected in hospitals or maternity hospitals - places of big crowds, are carriers of the bacteria. Also an additional risk factor is inadequate compliance with sanitary and personal hygiene rules.
- Staphylococcus aureus most often airborne. This can occur upon contact not only with a sick person, but also with a carrier of a bacterium, in which it does not manifest in any way. Also this microorganism, actively developing on dirty surfaces and in dust, can transmitted through contact with various objects, or, for example, in public transport.
- Staphylococcus aureus bacterium easily enters the body human through wounds and scratches, burns - any damage that violates the integrity of the skin. That is why nursing mothers can easily become infected with staphylococcus through cracks in the nipples, which is usually the cause of purulent mastitis.
- In general, Staphylococcus aureus is easily transmitted through mucous membranes (nasopharynx, genitals) or eyes, as well as through the blood. Therefore, frequent transmission of the disease during pregnancy and childbirth or through sexual intercourse.
- Staphylococcus aureus may be passed to infant with mother's milk. But this situation is ambiguous, because it is mother's milk that gives the baby immune protection against this bacterium. If staphylococcus is found in a mother or baby, the decision to stop or continue breastfeeding should be made by a doctor.
- The risk of transmission of Staphylococcus aureus increases in people exposed to various invasive (associated with the violation of the integrity of the natural barriers of the body) procedures. Frequent injections intramuscular catheters, hemodialysis, and artificial lung ventilation, transplants, medical instruments, and dressings — all this can cause infection. Moreover, diseases caused by the bacterium Staphylococcus aureus are particularly active develop on the background of weakened immunity, often associated with long-term illnesses and antibiotics, surgery and various medical procedures.
- Staphylococcus aureus bacterium easily breeds on food, most often it is meat, eggs, dairy products, sausage, cakes and pastries. You need to be extremely careful when checking the shelf life of products, and carefully follow the rules for their storage to avoid bacteria in the body.
Despite the fact that the bacterium Staphylococcus aureus is widespread, resistant to antibiotics and poses a serious threat to human health, do not panic. Protect yourself and your loved ones from the diseases caused by this microorganism, you can, in compliance with sanitary rules and personal hygiene.
A healthy lifestyle that forms strong immunity will protect you from any diseases!
