Staph infections are caused by bacteria called staphylococcus. They most often affect the skin. They can go away on their own, but sometimes they need to be treated with antibiotics.
Most people recover from staphylococcal infections. Antibiotics typically kill the bacteria shortly after treatment begins. But reinfection and the need for additional treatment sometimes occur.
Staph can cause serious infections if it gets into the blood and can lead to sepsis or death. Staph is either methicillin-resistant staph (MRSA) or methicillin-susceptible staph (MSSA).
The infections may recur over many months. Eventually some degree of immunity develops and the episodes become less frequent. However episodes may continue to occur for up to 2 years. In general, there is no detectable problem with a person's immunity to explain the infections.
Recurrent infections occur in nearly half of all patients with S. aureus SSTI. Epidemiologic and environmental factors, such as exposure to health care, age, household contacts with S. aureus SSTI, and contaminated household fomites are associated with recurrence.
Bacteremia. Also known as a bloodstream infection, bacteremia occurs when staph bacteria enter the bloodstream. A fever and low blood pressure are signs of bacteremia.
Lungs and heart: If the bacteria get into your lungs, you can develop pneumonia and other breathing problems from the abscesses that can form. Staph bacteria can also damage the heart valves and lead to heart failure.
Infections of the skin or other soft tissues by the hard-to-treat MRSA (methicillin-resistant Staphylococcus aureus) bacteria appear to permanently compromise the lymphatic system, which is crucial to immune system function.
Staph bacteria are very adaptable. Many varieties have become resistant to one or more antibiotics. For example, today, most staph infections can't be cured with penicillin. Antibiotic-resistant strains of staph bacteria are often described as methicillin-resistant Staphylococcus aureus (MRSA) strains.
When common antibiotics don't kill the staph bacteria, it means the bacteria have become resistant to those antibiotics. This type of staph is called MRSA (Methicillin-Resistant Staphylococcus aureus). MRSA was first identified in the 1960's and was mainly found in hospitals and nursing homes.
Model of Staphylococcus aureus biofilm development
aureus biofilm development is described in five stages: A) attachment, B) multiplication, C) exodus, D) maturation, and E) dispersal.
Keep your hands clean by washing them thoroughly with soap and water. Or use an alcohol-based hand sanitizer. Keep cuts and scrapes clean and covered with bandages until they heal. Avoid contact with other people's wounds or bandages.
Anyone can develop a staph infection, although certain groups of people are at greater risk, including people with chronic conditions such as diabetes, cancer, vascular disease, eczema, lung disease, and people who inject drugs.
It is the leading cause of skin and soft tissue infections such as abscesses (boils), furuncles, and cellulitis. Although most staph infections are not serious, S. aureus can cause serious infections such as bloodstream infections, pneumonia, or bone and joint infections.
Staph food poisoning is characterized by a sudden start of nausea, vomiting, and stomach cramps. Most people also have diarrhea. Symptoms usually develop within 30 minutes to 8 hours after eating or drinking an item containing Staph toxin, and last no longer than 1 day.
Staph skin infections, including MRSA , generally start as swollen, painful red bumps that might look like pimples or spider bites. The affected area might be: Warm to the touch. Full of pus or other drainage.
Invasive staph infections, such as sepsis (also called septicemia), endocarditis, and pneumonia, typically cause significant illness that may include fever, fast breathing or shortness of breath, fatigue, and sometimes confusion or disorientation.
Even if your test is positive for Staph, it does not mean you have an infection and your surgery will not be cancelled or delayed. A positive test means that prior to your surgery you will need to use a nasal ointment and bathe or shower with a special soap.
What causes staph infections? Some people carry staph bacteria on their skin or in their noses, but they do not get an infection. But if they get a cut or wound, the bacteria can enter the body and cause an infection. Staph bacteria can spread from person to person.
Warm, humid environments can contribute to staph infections, so excessive sweating can increase someone's chances of developing an infection. People with skin problems like burns or eczema may be more likely to get staph skin infections.
Each case of staph infection is different, but most often staph will resolve in 1-3 weeks. Once you complete your antibiotic treatment, you'll no longer be contagious, but you should keep any skin infection clean and covered until it is completely gone.
Stage IV: abscesses mature and rupture on the organ surface to initiate new rounds of infections. Genes required for specific stages of staphylococcal abscess development are in red above the corresponding stage of infection.
Dalbavancin has a prolonged half-life up to 8.5 days that facilitates once-a-week dosage [16, 17]. After intravenous injection of a single 1 g dose, serum dalbavancin concentrations stay above the minimum inhibitory concentration for MRSA for about 8 days [18]. The terminal half-life of dalbavancin is about 14 days.
