A breach in the skin’s top layer creates a portal to the deeper dermis through which bacteria can slip and launch a full-blown infection. If you are wondering what bacteria causes cellulitis then the most common forms are Streptococcus pyogenes and Staphylococcus or other exogenous bacteria. Antibiotic-resistant methicillin-resistant Staphylococcus aureus (MRSA) is also becoming more common.
Understanding Cellulitis Pathophysiology
As mentioned, the bacteria gain entrance from a break in the skin, bug bite, intravenous catheter (UV), burn, or incision. Prolific replication takes place causing a widespread infection that can reach deep through the skin’s layers to the tissue.
Let go, cellulitis pathophysiology will culminate in sepsis if the body’s natural immune system does not conquer the bacterial invaders. The infection starts from the localized area of infringement and then spreads. In addition, folliculitis, a splinter, prosthetic device, or abscess can also serve as an entry into the body’s system.
Antibiotic-Resistant MRSA Cellulitis
MRSA is an interesting strain of the common staph bacteria that has been dubbed a superbug for it’s ability to resistant even the most dynamic drugs. MRSA infections often take on the appearance of a spider bite and then spread to become MRSA cellulitis. The bacteria’s ability to spread is astonishing. It takes only a few hours to go from a minor disease to a full-blown pandemic of the skin. Often with this form of infection, the skin forms an abscess that requires surgical drainage. Cellulitis vs MRSA is very serious and requires prompt medical treatment.
Where does MRSA come from?
- They estimate that two out of 100 individuals have MRSA bacteria actively living on their bodies.
- Hospitals remain the number one source of MRSA, which is why many develop it after surgery.
Cats and dogs can also carry the virulent bacteria on their skins.
- A trip to the beach can prove deadly if you have open sores because MRSA thrives in sand and salt water. It lives in saltwater for days and actively reproduces in the granules of sand.
- Spread from coughing or sneezing
- Poor personal hygiene
- Sharing razors
- Athletic gear
- Unsanitary living conditions
Outlining Etiology of Cellulitis
Your skin home to a thriving population of millions of indigenous flora. They are harmless until you cut yourself. Streptococcus pyogenes usually cause lymphangitis and fever. The bacteria also cause recurrent bouts of cellulitis. The lower extremities, chronic venous stasis, and saphenous vein harvest are all prime locations. In addition, when studying etiology of cellulitis, you realize that certain health conditions put a person at an increased risk such as chronic lymphedema, Milroy’s disease, lymph node dissection (especially those associated with a mastectomy), and elephantiasis. Staphylococcal and streptococcal species are high in drug users.
Other bacteria that cause cellulitis includes:
- Haemophilus influenzae: Leading cause of facial cellulitis in children. However, the B vaccine now prevents the infection in children so incidences have become rare.
- Pasteurella multocida: If you get bit by a cat you stand a strong chance of contracting
- Pasteurella multocida bacteria. The mouth of the feline is swarming with this form of bacteria.
- Dogs, raccoons, skunks, and other mammals also harbor the pathogen. Aeromonas hydrophila:
- This is a freshwater pathogen. Pseudomonas aeruginosa: They credit the pathogen with three soft tissue diseases: Ecthyma gangrenosum, which occurs in neutropenic patients, hot tub folliculitis and cellulitis from penetration such as a rusty nail.
- Gram-negative bacillary (rod) cellulitis: P. aeruginosa often occurs in hospitalized patients, as a cellulitis nursing diagnosis in elderly assisted care patients, or those with HIV/AIDS.
- They must run culture and sensitivity tests to make a full diagnosis.
Understanding Cellulitis Bacteria
Your body’s immune system can normally cope with most forms of bacteria. As outlined, cellulitis bacteria is made of numerous types and some are more aggressive than others.
All require antibiotics to treat. Although some people undergo naturopathic care protocols with some success.
Wondering Is Cellulitis Contagious?
When you first lay your eyes on a cellulitis infection, you might gasp in shock. The appearance is often horrific. The first thing that goes through your mind is fear and wondering is cellulitis contagious. In most cases, the bacteria that cause cellulitis are not dangerous if you have no skin lesions and your immune system is functioning.
However, MRSA is contagious if you have a wound. Also, eye cellulitis contagious is a reality.
Is Periorbital Cellulitis Contagious?
If you have an infection of the eyelid or surrounding ocular region, then you could have periorbital cellulitis contagious disorder. Any trauma to the eye area can cause this form of infection. Young children are at an increased risk. Prompt treatment is imperative or the infection could spread into the eye socket to become orbital cellulitis. The condition can lead to permanent vision loss and other problems.
The bacteria can also cause impetigo of the eyelid. Swelling, redness, and blisters form. This a serious condition and you will need to be hospitalized to receive adequate life-saving care and prevent the spread to others. Drug therapy is highly successful. You will need to throw away all makeup such as mascara, eyeshadow, eyeliner, contact lenses, and other eye products to prevent reinfestation.
