The Full Form of MSSA is‍ Methicillin Sensitive Staphylococcus Aureus.

MSSA, or methicillin-susceptible Staphylococcus aureus, is an infection caused by a type of bacteria commonly found on the skin. You might have heard it called a staph infection.

Treatment for staph infections generally requires antibiotics. Staph infections are classified according to how they respond to this treatment:

• MSSA infections are treatable with antibiotics.
• Methicillin-resistant Staphylococcus aureus (MRSA) infections are resistant to certain antibiotics.

Both types can be serious and even life threatening. This article provides an overview of MSSA symptoms, causes, and treatment.

MSSA symptoms vary according to where the staph infection is located. MSSA can affect the skin, blood, organs, bones, and joints. Symptoms may range from mild to life threatening.

Some possible signs of an MSSA infection include:

• Skin infections. Staph infections that affect the skin may cause symptoms such as impetigo, abscesses, cellulitis, pus bumps, and boils.
• Fever. A fever signals that your body is fighting an infection. A fever may be accompanied by sweating, chills, confusion, and dehydration.
• Aches and pains. Staph infections can cause pain and swelling in the joints as well as headaches and muscle pain.
• Gastrointestinal symptoms. Staph bacteria can cause food poisoning. Common symptoms associated with staph food poisoning include nausea, abdominal pain, vomiting, diarrhea, and dehydration.
