Pictures of methicillin-resistant Staphylococcus aureus, or MRSA, infections can be found on reputable medical websites, such as WebMD, Mayo Clinic and the United States Centers for Disease Control and Prevention websites. According to the CDC website, most MRSA infections start off with the appearance of spider bites or bumps that are painful, swollen and red.
According to the CDC, MRSA infections are most commonly skin infections that look like boils or pustules that are red, swollen and painful and that have drainage, often pus. The infections commonly occur in areas where there is visible skin trauma, such as bites, scratches or abrasions. Many times, the occurrences are in areas that are covered in hair, such as the armpit, groin, back of neck, buttocks or even in facial hair, such as a beard.
The CDC provides photos of MRSA bacteria, as well as photos of various cutaneous abscesses shown in different stages and different areas of the body. The WebMD website provides a slideshow of the tiny cluster bacteria as seen under a microscope as well as various types of MRSA skin infections. According to WebMD, MRSA is known as a "superbug," and even though most cases are minor, there are some that can be considered life threatening.
The Mayo Clinic website offers a large amount of resources about MRSA, including how to prevent it and what puts people at risk of the infection, but the site only offers one picture of the infection at an early stage.
