Staph Infection

History of Staph Infection

In 1880, Scottish surgeon Sir Alexander Ogston was the first to identify staphylococci in pus from a surgical abscess in a knee joint, describing the clusters as resembling "bunches of grapes".

In 1884, German physician Friedrich Julius Rosenbach categorized the bacteria based on colony colour, distinguishing Staphylococcus aureus (named after the Latin word aurum, meaning gold) and Staphylococcus albus (Latin for white). S. albus was later renamed S. epidermidis due to its widespread presence on human skin.

Modern Understanding of Staph Infection

A staph infection happens when bacteria called staphylococcus, or "staph" get into your body. Surprisingly, about 1 in 4 people naturally carry staph bacteria on their skin, in places like the nose, mouth, private parts, or bottom, without showing any signs of infection. The infection often starts with a small cut, which lets the bacteria in, and can show up as a yellowish crust on the skin.
Surface Staph Infections
Staph infections affecting the skin can lead to conditions such as:
Boils – painful, pus-filled lumps
Impetigo – red sores with a honey-colored crust
Cellulitis – swollen, red, tender skin that may ooze fluid
These infections are typically treated with topical antibiotics.
When staph infections become dangerous
In some cases, a staph infection can spread beyond the skin, infiltrating muscle tissue and even the cerebrospinal fluid (CSF). This progression can lead to serious complications. Symptoms develop in the following stages:

Initial Symptoms
Pain begins in the lower back.
The pain gradually worsens over time.
Within hours, tingling sensations develop in the legs.
Sitting improperly or on a hard surface exacerbates the pain due to spinal nerve compression.
Antibiotics are crucial at this stage.
⚠️ WARNING: Hot showers or baths can accelerate symptom progression and significantly worsen the condition.
Progression of the Infection
After two days, the legs may become paralyzed.
Severe back pain persists as the infection spreads up the spine, increasing the risk of permanent paralysis.
Surgery may be required to remove the infection, followed by intensive antibiotic treatment.
Neurological Complications
A spinal puncture may be necessary to reduce pressure in the spine and brain. However, this procedure carries a risk of spreading the infection.
Normally, cerebrospinal fluid is clear, but in cases of severe staph infection, it turns opaque and may be ejected forcefully due to increased pressure.
As pressure in the brain rises, seizures may occur, leading to neurological shutdown.
Critical Stage
Without immediate treatment, the patient may slip into a coma due to excessive brain pressure.
Surgery to relieve pressure is often necessary.
Antibiotics must be administered carefully to prevent harmful interactions with other medications.
One of the signs that the staph infection has reached the brain and CSF is if warming the body produces immense pain in the legs and back causing paralysis.

Causes of Staph Infection

Boils  
The most common type of staph infection is a boil, which is a pocket of pus that forms in a hair follicle or oil gland. The affected area usually becomes red, swollen, and tender.  

Impetigo  
Impetigo is a contagious and often painful rash caused by staph bacteria. It is characterized by large blisters that may ooze fluid and develop a honey-colored crust.  

Cellulitis  
Cellulitis is a deeper skin infection that leads to redness, swelling, and tenderness. It can also cause sores or areas that ooze discharge.  

Staphylococcal Scalded Skin Syndrome  
Staph bacteria can produce toxins that lead to staphylococcal scalded skin syndrome, which primarily affects babies and young children. Symptoms include fever, rash, and blisters. When the blisters break, the top layer of skin peels away, leaving a raw, red surface that resembles a burn.  

Bacteremia (Bloodstream Infection)  
Bacteremia occurs when staph bacteria enter the bloodstream, leading to symptoms such as fever and low blood pressure. The bacteria can spread to deeper parts of the body, causing infections in:  

Brain (Meningitis)  
When staph bacteria infect the brain, it can lead to meningitis, a serious condition causing inflammation of the membranes surrounding the brain and spinal cord. Symptoms may include severe headaches, fever, stiff neck, confusion, and sensitivity to light. Without prompt treatment, it can lead to complications such as seizures or permanent neurological damage.  

Heart (Endocarditis)  
Staph bacteria can infect the inner lining of the heart (endocardium), leading to endocarditis. This condition can damage heart valves and disrupt normal blood flow, potentially resulting in heart failure or other life-threatening complications. Symptoms may include fever, chills, fatigue, shortness of breath, and swelling in the legs or abdomen.

Treatments for Staph Infection

Topical Antibiotics: Mupirocin (Bactroban) is often used for mild cases like impetigo.

Intravenous (IV) Antibiotics: For more serious infections, especially if oral antibiotics fail or if the infection spreads, IV antibiotics may be used.
