An infection with skin staphylococci is caused by a type of bacteria known as Staphylococcus aureus. This common bacterium can cause various skin infections, from slight to serious. Identifying the symptoms of a staphylococcal infection is crucial for timely diagnosis and treatment. In this visual guide, we will explore common skin infections caused by staphylococcus bacteria, accompanied by images and essential information to help you recognize them.

Images of skin infections by staphylococci:

  1. Bowls: staphylococcal bacteria usually cause painful boards, which appear as red and swollen lumps on the skin. These boils can be filled with pus, and their centers can develop a white or yellowish head. Boils may appear individually or in groups.
  2. IMPETIGO: Another common staphylococcal infection is the Imletigo, which is more frequent in children. It manifests itself in the form of red sores that suppurate a honey liquid and develop a yellowish brown crust. These sores usually chop and can extend to other parts of the body by scratching or contact.
  3. Cellulite: staphylococcal bacteria can also cause cellulite, a deeper skin infection that affects underlying tissues. The affected area is reddened, swells and becomes sensitive. In severe cases, infection can spread rapidly and cause fever or chills.

Important information: It is important to direct that these images have illustrative purposes and may not faithfully represent all cases. If you suspect you have a staphylococcal infection or note some worrying symptom, consult a healthcare professional to obtain an appropriate diagnosis and treatment plan.

Recognizing the visual characteristics of staphylococci infections in the skin can help understand the nature and severity of infection. However, it is essential to consult a medical professional to obtain a precise diagnosis and proper treatment. A rapid intervention is crucial to prevent complications and promote rapid recovery.

Understanding Staph Infection: Symptoms, Causes, and Treatment Options

Recognizing the symptoms of staphylococcal infection is crucial for early detection and rapid treatment. The most common symptoms are redness, swelling and pain in the place of infection. The affected area can also be hot to the touch and full of pus or other fluids. In the most serious cases, fever, chills and fatigue may appear. It is important to note that these symptoms may vary depending on the location of the infection.

  • Common symptoms of staphylococcal infection:
    1. Pain and swelling at the place of infection
    2. Redness and heat in the affected area
    3. Pus or blisters full of liquid
    4. Fever and chills
    5. Fatigue

The causes of staphylococcal infection can be diverse, since the bacteria can spread through direct contact with an infected person, contaminated objects or even through cuts or skin wounds. In addition, people with weakened immune systems or chronic conditions such as diabetes are more likely to develop staphylococci infections. Maintaining good personal hygiene, avoiding narrow contact with infected people and properly cleaning and covering wounds are key preventive measures.

“Staphylococcal infection can spread through ski n-t o-skin contact, sharing personal objects or playing contaminated surfaces.”

Staphylococcal infections treatment options vary depending on the severity and location of infection. Mild cases are usually treated with topical antibiotics or antiseptic creams to help reduce symptoms and avoid greater propagation. However, the most serious cases may require oral or intravenous antibiotics to eliminate bacteria. It may also be necessary to drain abscesses or infected liquid to favor healing.

Treatment options for staphylococcal infection: Common antibiotics:
Topical treatments: Neomycin, bacitracin
Oral antibiotics: Flucloxacillin, clindamycin
Intravenous antibiotics: Vancomycin, Linezolid

It is important to seek medical attention if you suspect that you have a staphylococcal infection, especially if the symptoms get worse or if you suffer a chronic disease that weakens your immune system. An early diagnosis and proper treatment can help prevent complications and favor complete recovery.

What is Staph Infection?

Staphylococcus aureus bacteria can cause various infections, such as skin infections, respiratory infections, and even serious bloodstream or organ infections. When the bacteria enters the body, it can multiply rapidly, causing various symptoms depending on the affected area. Skin infections, for example, can lead to boils, impetigo, cellulitis, or staphylococcal scalded skin syndrome.

  • Boils: These are painful, pus-filled lumps that appear on the skin. They usually start as a red, swollen lump that fills with pus before rupturing and draining.
  • Impetigo: This highly contagious skin infection causes red sores that may open, ooze fluid, and form a yellowish-brown scab. It usually affects children.
  • Cellulitis: Cellulitis is a bacterial skin infection that can cause redness, swelling, and warmth in the affected area. It may also be accompanied by fever and chills.
  • Staphylococcal scalded skin syndrome: This serious infection primarily affects infants and young children. It causes general redness, blisters and peeling of the skin, similar to a burn or scald.

“Staph infection is very contagious and can easily spread from person to person through direct contact or by touching contaminated objects. It is important to practice good hygiene, especially washing your hands frequently with soap and water, to prevent the spread of staph infection.”

Identifying Staph Infection Symptoms on the Skin


  • Redness and swelling: One of the main indicators of a staph infection is the presence of redness and swelling on the skin. The affected area may appear swollen and feel hot to the touch.
  • Pus-filled lumps: Staph infections often cause small pus-filled bumps, known as impetigo, to form. These bumps can itch and break, which can cause the infection to spread to nearby areas.
  • Pain or tenderness: Staph infections may be accompanied by pain or tenderness in the affected area. These discomforts may worsen with movement or pressure exerted on the skin.
  • Crusty or scaly skin: In some cases, staph infections can cause the skin to become crusty or scaly. This can occur when bacteria penetrate the deeper layers of the skin, leading to more serious infections such as cellulitis.

It is important to note that these symptoms can vary depending on the severity and type of staph infection. Additionally, people with weakened immune systems, such as those with diabetes or HIV/AIDS, may experience more serious symptoms and complications.

To help identify the symptoms of staph infection, it is crucial to observe the skin for any changes and consult with a healthcare professional. A quick and accurate diagnosis can lead to appropriate treatment, helping to prevent further complications.

Common Causes and Risk Factors of Staph Infection

1. Wounds and cuts in the skin: Staph infections usually occur when bacteria enter the body through a break or cut in the skin. This can include wounds, surgical incisions, insect bites, or even small cuts and scrapes. It is crucial to quickly clean and disinfect any skin breaks to minimize the risk of bacterial invasion. People with a weakened immune system, such as those with diabetes or HIV/AIDS, are especially susceptible to contracting staph infections through skin breaks.

Risk factor: Unsanitary environments: Poor hygiene habits, crowded conditions, and lack of access to clean water and sanitation facilities can increase the risk of staph infection. People who frequently visit or work in environments with a high bacterial load, such as hospitals, gyms or schools, are also at increased risk.
Risk factor: Sharing personal items: Close contact with an infected person or sharing personal items such as towels, razors, or clothing can facilitate the spread of staph bacteria. This is especially common in homes or community settings where personal hygiene practices may be inadequate.
Risk factor: Pre-existing skin conditions: Certain skin conditions, such as eczema, psoriasis, or athlete’s foot, create an environment in which staph bacteria can proliferate. The compromised skin barrier and increased humidity provide a suitable breeding ground for bacteria, increasing the likelihood of infection.

2. Weakened immune system: People with a weakened immune system are at higher risk of developing staph infections. Conditions such as cancer, diabetes, HIV/AIDS, or undergoing chemotherapy or immunosuppressive therapy can compromise the body’s natural defense mechanisms, making it easier for staph bacteria to cause infections. In addition, newborns, the elderly and people with chronic diseases are also more vulnerable to staph infections due to their weakened immunity.

3. Medical procedures: Certain medical procedures or treatments can increase the risk of staph infection. Invasive procedures such as surgery, intravenous catheter placement, and dialysis expose the body to potential sources of staphylococcal bacteria. Hospitals and healthcare facilities are hotbeds for bacteria, and the presence of a weakened immune system further amplifies the risk.

  • Regular handwashing and maintaining good hygiene practices can significantly reduce the risk of staph infection.
  • People with pre-existing skin conditions should take special care to avoid skin breakdown and keep affected areas clean and dry.
  • Avoid sharing personal items, especially in common settings or with people who may have an active staph infection.
  • In healthcare facilities, appropriate sterilization and disinfection protocols must be followed to prevent the spread of staphylococci.

By staying informed about the most common causes and risk factors for staph infections, people can proactively protect themselves and reduce the likelihood of contracting this potentially harmful bacterial infection.

Exploring Different Types of Staph Infections on the Skin

One type of staph infection is known as cellulitis. Cellulitis is a bacterial skin infection characterized by redness, swelling and heat in the affected area. It can occur anywhere on the body and usually appears after a break in the skin, such as a cut or wound. The infection can spread quickly, and people with weakened immune systems or underlying illnesses are especially susceptible.

  • Cellulite presents as localized redness of the skin, tenderness and swelling.
  • The affected area may be warm to the touch.
  • In severe cases, cellulitis can lead to the formation of abscesses or pockets of pus in the skin.

Cellulitis is a common staph skin infection characterized by redness, warmth, swelling, and tenderness in the affected area. It can progress rapidly and lead to abscess formation.

Another type of staph skin infection is impetigo. Impetigo is a contagious bacterial infection that primarily affects children. It is characterized by the formation of small red bumps or blisters that open, ooze fluid and form a yellowish crust. It usually appears on the face, around the mouth and on the hands. Impetigo can spread easily through direct contact and usually affects people who live in close spaces, such as schools or daycares.

  1. Impetigo presents as small red bumps or blisters that break and develop a yellowish crust.
  2. It usually appears on the face, around the mouth and on the hands.
  3. Mild cases may resolve on their own, but severe or persistent cases may require antibiotic treatment.
Type of staph infection Main symptoms Common locations
Cellulitis Localized redness, warmth, swelling, tenderness Anywhere on the body
Impetigo Small red bumps or blisters, yellowish crust Face, around the mouth, hands

Staph Infection Complications: When to Seek Medical Help

1. Spread of infection: Staph infections can easily spread from one area of skin to another or even to other people through direct contact. If you notice that the infection seems to spread rapidly, with new areas of redness, swelling and pain appearing, it is important to seek medical help. This could indicate a more aggressive strain of staph or a weakened immune system unable to effectively fight the infection.

2. Development of abscesses: Staph infections can sometimes lead to the formation of abscesses, which are pockets of pus that form under the skin. Abscesses may be painful, warm to the touch, and may not heal on their own. If you notice the presence of an abscess, it is recommended to seek medical help for proper evaluation and treatment. A healthcare professional may need to drain the abscess to remove infected tissue and prevent further complications.

Remember, if you have a staph infection and experience any of the following complications, it is important to see a healthcare professional immediately:

  • New or worsening symptoms
  • persistent fever
  • Difficulty moving or using the affected area
  • Signs of systemic infection, such as chills or vomiting

By acting quickly and seeking medical help when necessary, complications from staph infections can be minimized and appropriate treatment administered to promote a faster recovery.

Treatment Options for Staph Infection on the Skin

When it comes to treating a staph skin infection, the choice of treatment usually depends on the severity of the infection and the person’s overall health. In mild cases, topical antibiotics are often prescribed to combat the infection. These medications, such as mupirocin or retapamulin, are applied directly to the affected area and act by eliminating the bacteria causing the infection. It is essential to follow the instructions provided by your healthcare professional to ensure effective use of topical antibiotics.

Medical Treatment Options:

  • Oral antibiotics: in the most serious cases or when the infection has spread beyond the skin, it may be necessary to administer antibiotics orally. These antibiotics, such as cephalexin or clindamycin, help eliminate organism bacteria. The duration of the treatment can vary depending on the extension of the infection and response of the person to the medication.
  • Incision and drainage: When a staphylococcal infection forms an abscess, which is a pus bag, it is possible that a healthcare professional has to perform an incision and drainage procedure. During this procedure, the abscess is opened, which allows the pus to drain. This helps relieve pain and favors healing.
  • Wound and hygiene care: adequate care of wound and hygiene are crucial in the treatment of skin staphylococci infection. Keeping the affected area clean, dry and covered with sterile dressings can avoid greater propagation of the infection and facilitate healing. It is important to follow all the specific instructions provided by the health professional in relation to the care of the wound.

Note: It is essential to complete the antibiotic treatment prescribed by the health professional, although the symptoms improve. Interrupting the treatment ahead of time can cause bacteria to develop resistance, which would make the treatment of future infections difficult.

In some cases, it may be necessary to identify and address the underlying cause of staphylococcal infection. This could involve the treatment of any underlying medical condition that weakens the immune system or the practice of good hygiene habits to reduce the risk of recurrence. Consultation with a healthcare professional is essential to obtain an accurate diagnosis and an adequate treatment plan for a skin staphylococci infection.

Preventing Staph Infections: Tips for Good Hygiene and Cleanliness

  • Washing your hands regularly: washing your hands with soap and water is one of the most effective ways to prevent staphylococcal infections. Be sure to wash your hands well for at least 20 seconds, paying special attention to the areas between the fingers and under the nails. It is especially important to wash your hands before eating, after going to the bathroom and after touching potentially contaminated surfaces.
  • Keeping wounds clean and covered: any open sore or wound can serve as a point of entry for staphylococcal bacteria. Always clean the wounds quickly with soap and water, and apply an adequate antibiotic ointment before covering them with a sterile bandkestage or dressing. Keeping wounds covered will not only avoid the entry of staphylococcal bacteria, but will also protect them from external contaminants.
  • Avoiding close contact with infected people: staphylococcal infections can be very contagious, especially when there are open sores or skin lesions. If you know someone who has a staphylococcal infection, try to limit close contact until the infection has disappeared. This includes avoiding share objects such as towels, clothing or personal toilet items.

Staphylococcal infections can be very persistent and treatment resistant, so prevention is even more important.

In addition, maintaining a clean environment is essential to avoid the spread of staphylococcal bacteria. Here are some additional measures to guarantee cleaning:

  1. Frequent cleaning and disinfection: clean and disinfect regularly the surfaces that are frequently touched, such as doors, light switches and countertops, using an adequate disinfectant. Pay attention to shared spaces, especially in health centers, gyms and public bathrooms.
  2. Proper washing of clothing and sheets: wash clothes, towels and sheets, especially those used by infected people, with hot water and detergent. If possible, use a high temperature dryer to further eliminate bacteria.
  3. Avoid sharing personal objects: abstain from sharing personal objects such as razor blades, towels and clothing, since they can potentially transfer staphylococcal bacteria from one person to another.
