Methicillin-resistant Staphylococcus aureus (MRSA) is a bacteria that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus – or staph – because it's resistant to some commonly used antibiotics.
Staph infections are caused by several different types of staph germs, including: methicillin-resistant Staphylococcus aureus (MRSA) methicillin-susceptible Staphylococcus aureus (MSSA) vancomycin-intermediate Staphylococcus aureus (VISA)
Both types of staph infection often start on the skin and may appear as small, red bumps that may look similar to spider bites or pimples. The Centers for Disease Control and Prevention (CDC) state that MRSA infections often appear as flushed, swollen, and pus-filled skin.
Staph bacteria are usually harmless, but they can cause serious infections that can lead to sepsis or death. Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of staph infection that is difficult to treat because of resistance to some antibiotics.
In the most severe cases, they can cause toxic shock syndrome. TSS caused by other bacteria (such as staphylococcus) has a mortality rate of less than 3%. In this case, a streptococcal infection is more dangerous than a staphylococcal infection.
1. Necrotising fasciitis. Necrotising fasciitis is a severe infection of the skin, the tissue below the skin, and the fascia (fibrous tissue that separates muscles and organs), resulting in tissue death, or necrosis. The infection is rapid, fast-spreading and fatal if not detected and treated early.
If left untreated, staph infections can be deadly. Rarely, staph germs are resistant to the antibiotics commonly used to treat them. This infection, called methicillin-resistant Staphylococcus aureus (MRSA), causes severe infection and death.
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). Staph can spread in and between hospitals and other healthcare facilities, and in communities.
For serious staph infections, vancomycin may be required. This is because so many strains of staph bacteria have become resistant to other traditional antibiotics. This means other antibiotics can no longer kill the staph bacteria.
Sepsis, which is an infection of the bloodstream, and one of the most dangerous forms of staph infection. Symptoms include rapid breathing, an elevated heart rate, fever, chills, and disorientation. Staph infections in bones which also cause fever and chills accompanied by pain in the infected area.
The bacteria that cause staph infections live harmlessly on many people's skin, often in the nose and armpits and on the buttocks. They usually only cause an infection if they get into the skin – for example, through a bite or cut. Staph bacteria can spread to others through: close skin contact.
MRSA usually appear as a bump or infected area that is red, swollen, painful, warm to the touch, or full of pus. If you or someone in your family experiences these signs and symptoms, cover the area with a bandage and contact your healthcare professional.
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.
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.
If staph bacteria invade your bloodstream, you may develop a type of infection that affects your entire body. Called sepsis, this infection can lead to septic shock. This is a life-threatening episode when your blood pressure drops to an extremely low level.
Remember, if you have MRSA it is possible to spread it to family, friends, other people close to you, and even to pets. Washing your hands and preventing others from coming in contact with your infections are the best ways to avoid spreading MRSA.
One or More Swollen Red Bumps Draining Pus
Sometimes MRSA can cause an abscess or boil. This can start with a small bump that looks like a pimple or acne, but that quickly turns into a hard, painful red lump filled with pus or a cluster of pus-filled blisters.
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.
If the sore becomes unusually painful or red, get prompt medical attention. If red lines develop, that's a sign the infection is spreading and needs immediate medical attention.
Staphylococcus aureus bacteremia (SaB) causes significant disease in humans, carrying mortality rates of ∼25%.
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.
