MRSA infection is common in hospitals, prisons, and nursing homes, where people with open wounds, invasive devices such as catheters, and weakened immune systems are at greater risk of healthcare-associated infection. MRSA began as a hospital-acquired infection but has become community-acquired, as well as livestock-acquired.
Now, methicillin-resistant Staphylococcus aureus (MRSA) is not only a human pathogen causing a variety of infections, such as skin and soft tissue infection (SSTI), pneumonia, and sepsis, but it also can cause disease in animals, known as livestock-associated MRSA (LA-MRSA). [116] MRSA infections in both the hospital and community setting are ...
MRSA ST398 (Methicillin-resistant Staphylococcus aureus ST398) is a specific strain of Methicillin-resistant Staphylococcus aureus (MRSA). Staphylococcus aureus is a gram-positive, spherical bacterium that can cause a range of infections in humans and animals.
Staph infections have a multitude of different causes, such as: Open wounds – This is by far the biggest cause of staph infection. Any open wound, even ones as small as a paper cut, are vulnerable to being infected. Staph bacteria will enter the body through any open wound, so it is important to properly treat, disinfect, and bandage any wounds.
Abscesses are caused by bacterial infection, parasites, or foreign substances. Bacterial infection is the most common cause, particularly Staphylococcus aureus. The more invasive methicillin-resistant Staphylococcus aureus (MRSA) may also be a source of infection, though is much rarer. [22]
Methicillin-resistant Staphylococcus aureus (MRSA) is involved in up to a third of Type II infections. [4] Infection by either type of bacteria can progress rapidly and manifest as shock. Type II infection more commonly affects young, healthy adults with a history of injury. [2] Type III infection: Vibrio vulnificus is a bacterium found in ...
Bullous impetigo is a bacterial skin infection caused by Staphylococcus aureus that results in the formation of large blisters called bullae, usually in areas with skin folds like the armpit, groin, between the fingers or toes, beneath the breast, and between the buttocks.
Antibiotic choice should be guided by deep tissue culture, severity of the infection, presence or absence of osteomyelitis, prior antibiotic treatment, and previous or current MRSA infection. [17] Wounds without confirmed infection should not be treated with antibiotics, nor should be sent for culture.
