Antibiotics For Spider Bite Cellulitis

Diagnostic Approach To Cellulitis

Spider Bite MRSA Staph Infection What is it

When evaluating a patient with cellulitis, review systemic features. Potential portals of entry for infection should also be looked for. These include:

  • disruption to the skin barrier, insect bites, wounds, abrasions
  • pre-existing skin infection, tinea pedis, impetigo
  • underlying skin disease, eczema, psoriasis
  • lymphoedema or surgical disruption of the lymphatic or venous system
  • peripheral vascular disease with impaired arterial supply
  • chronic venous insufficiency.

It is important to consider less common causes of skin infection associated with specific clinical circumstances or exposures . In these cases, specimens should be collected for culture and sensitivity testing and treatment regimens broadened to cover likely pathogens. In difficult-to-treat or atypical infections, specialist opinion is recommended.

Cellulitis Complications And How To Prevent Them

Untreated cellulitis can lead to some serious medical conditions, including:

Another major complication is the infection spreading to your bloodstream, at which point the infection becomes life-threatening.

You can raise your chances of heading off complications by doing the following:

  • See a doctor if you have signs or symptoms of cellulitis.
  • Take your prescribed antibiotics as directed, and dont stop the medication early.
  • Notify your doctor if your symptoms dont improve within three days of starting an antibiotic.
  • Get plenty of rest to help your body heal faster. If the cellulitis is in your leg, elevate it to reduce swelling.

How Is A Spider Bite Diagnosed

Seeing the spider is the best way to confirm both a bite and the type of spider. Otherwise, there isnt a way to test for a spider bite or determine what bit you.

Your healthcare provider may make a diagnosis based on symptoms. Your provider may also send a sample of fluid from a blister to a lab to check for skin infections that cause similar symptoms, such as methicillin-resistant staphylococcus aureus .

Which Spiders Are Dangerous To People

There are at least 60 different spider species in America, but only a few pose any danger to humans. These more dangerous spiders include:

  • Black widows: These black spiders have a red hourglass shape on their bellies. Black widows like to build webs in woodpiles, building overhangs , fences and outhouses. They mostly live in the Western and Southern U.S.

  • Brown recluses: Sometimes called fiddleback or violin spiders, these brown spiders have a dark, violin-shaped mark on their heads. Brown recluses live in Midwestern and Southern states. They like dry, sheltered areas, such as piles of wood, rocks and leaves. Indoors, brown recluses seek out dark closets, attics and shoes.

Brown recluse spider

  • Hobo spiders: These brown spiders have a grey V-shaped pattern on their bellies. They build funnel-shaped webs in dark, moist basements, crawl spaces, window wells and woodpiles. Hobo spiders are mostly found in the Pacific Northwest.

In most cases, you can expect a spider bite from a non-venomous spider to heal within a week. However, the skin at the center of the bite can often turn into an open sore or ulcer that gets continually bigger until the surrounding skin dies. This ulcer shouldnt persist in growing for more than two weeks, with full healing potentially taking a month or more.

Flea Bites Vs Mosquito Bites

Fleas also feed off your blood and secrete saliva into your bloodstream. Flea bites look similar to mosquito bites and bed bug bites. Fleas travel by jumping, so their bites appear more random than bed bug and mosquito bites. Youre more likely to experience flea bites if you have dogs, cats or another pet that spends time outside.

If youre suffering from bug bites over a long period, your healthcare provider can help you identify the type of bite.

What Are The Signs & Symptoms Of Cellulitis

Cellulitis begins with a small area of skin that’s:

  • tender
  • warm
  • red

As this area begins to spread, a child may begin to feel ill and get a fever and, sometimes, chills and sweats. Swollen lymph nodes are sometimes found near the area of infected skin.

The time it takes for symptoms to start varies, depending on which bacteria cause the cellulitis. For example, a child with cellulitis caused by Pasteurella multocida, often found in animal bites, can have symptoms less than 24 hours after the bite. But cellulitis caused by other types of bacteria may not cause symptoms for several days.

Are There Different Kinds Of Ticks

Ticks are parasites that feed on warm-blooded hosts. They are related to mites and spiders because they are all arthropods. That means they have eight legs. There are many kinds of ticks. Some of the most common ticks in the U.S. include:

  • Blacklegged tick, also known as deer ticks.
  • Lone Star tick.
  • Dog tick .

Ticks can vary in size and color. Some are larger. Some are brown or reddish-brown. Others are darker. Some have lighter markings on their backs.

Treatment Of Cellulitis With Systemic Illness

Staph Infection OR Spider-Bite?!

More severe cellulitis and systemic symptoms should be treated with fluids, intravenous antibiotics and oxygen. The choice of antibiotics depends on local protocols based on prevalent organisms and their resistance patterns and may be altered according to culture/susceptibility reports.

  • Penicillin-based antibiotics are often chosen
  • Amoxicillin and clavulanic acid provide broad-spectrum cover if unusual bacteria are suspected
  • Cephalosporins are also commonly used
  • Clindamycin, sulfamethoxazole/trimethoprim, doxycycline and vancomycin are used in patients with penicillin or cephalosporin allergy, or where infection with methicillin-resistant Staphylococcus aureus is suspected
  • Broad-spectrum antibiotics may also include linezolid, ceftaroline, or daptomycin

Sometimes oral probenecid is added to maintain antibiotic levels in the blood.

Treatment may be switched to oral antibiotics when the fever has settled, cellulitis has regressed, and CRP is reducing.

What Is The Prognosis For People Who Have Cellulitis

Most people feel better after about five days of taking antibiotics. Severe cellulitis may last two weeks or longer. To completely get rid of the infection, its important to take all of the antibiotics, even if you start to feel better.

Sometimes, symptoms get worse for a few days after you start treatment. This worsening of symptoms may be the result of bacteria dying off.

Having cellulitis once increases your risk of getting the infection again, usually in the same area. People who have weak immune or lymphatic systems are most at risk for recurrent cellulitis.

How Does A Tick Bite Affect My Body

You might not even know youve been bitten by a tick. Most dont cause pain or itching but some do. Some tick bites dont cause disease. Sometimes you can remove the tick before it can pass on any germs.

The tick bite itself may not cause symptoms except for some type of skin reaction, like a rash or a small hard lump. The infection that tick bites can give you may begin to cause symptoms.

Portals Of Bacterial Entry

Cellulitis occurs where the skin has been broken. Trauma , insect bites, animal and human bites, surgical wounds, burns, sites of IV catheter insertion or IV injection of illicit drugs , and even small, imperceptible cracks in the skin predispose patients to cellulitis.

The infection is also associated with other skin conditions, including abscesses, furuncles, carbuncles, impetigo, varicella, and tinea pedis. When assessing patients with lower-extremity cellulitis, clinicians must be sure to examine the feet for interdigital dermatophytic infections and treat as necessary with topical antifungal agents.

Skin Care And Prevention

GEMC

If you have a wound on your skin, keeping it clean and well cared for can help reduce your risk of cellulitis. And if you’re prone to skin cracks, either due to a condition such as eczema or because you have dry skin, applying a thick moisturizer can help create a barrier against bacteria and protect against infection.

How Periorbital Cellulitis Is Diagnosed

If your doctor suspects periorbital cellulitis, theyll begin by a physical examination of your eyes for signs of injury.9

In addition, your doctor may examine your eye movements and response to light.

They may use tools such as X-rays and CT scans to have a clear picture of the infected area.

If your doctor suspects that underlying problems are the cause of the infection, they will do further investigation.

In this case, they may take a fluid sample such as blood cultures from the affected eye or other areas to find out the type of bacteria causing the problem.

For example, if sinusitis is the suspected cause, your doctor will take a sample of the paranasal sinus fluid to investigate further.

The paranasal sinus is the drainage that keeps the nose free of harmful bacteria. It is located in your head near the nose and eyes.

Once your doctor identifies the bacteria causing your eye infection, they will then proceed to administer treatment.

Causes Of A Bug Bite Infection

All bug bites can lead to infection because they are caused by breaks in the skin. Fortunately, most bug bites do not become infected.

Bugs that people typically encounter include:

The most common bacterial organisms that cause a skin infection after a bug bite are group A Streptococcus and Staphylococcus aureus. These bacteria are generally found in the environment and on the skin. They can enter the body when the bite of a bug punctures it. The bacteria do not come from bug saliva.

The bacteria can also enter the body when a person scratches at the bite, since scratching also breaks the skin.

Special Precautions For People With Diabetes

What Are The Risk Factors For Cellulitis From A Bug Bite

Children spend more time outside and tend to get more bug bites than adults. Their fingernails are often dirtier, too. These factors increase a childs risk for cellulitis.

If you have a weak immune system due to autoimmune disease, cancer or another illness, you may be more prone to cellulitis. The immune system helps your body fight off infections.

Other cellulitis risk factors include:

You can use a washable marker to draw a border around the red, swollen bug bite area to track its size. You should contact your healthcare provider immediately if redness, swelling or blisters expand outside this border. Your provider may monitor the bite infection this way to make sure the infection clears up with treatment and doesnt get worse.

What Causes Cellulitis

Cellulitis is usually caused by a bacterial infection.

The bacteria can infect the deeper layers of your skin if it’s broken, for example, because of an insect bite or cut, or if it’s cracked and dry.

Sometimes the break in the skin is too small to notice.

You cannot catch cellulitis from another person, as it affects the deeper layers of the skin.

You’re more at risk of cellulitis if you:

  • have poor circulation in your arms, legs, hands or feet, for example, because you’re overweight
  • find it difficult to move around
  • have a weakened immune system, for example, because of chemotherapy treatment or diabetes
  • have lymphoedema, which causes fluid build-up under the skin
  • inject drugs
  • have a wound from surgery
  • have had cellulitis before

When To See A Doctor

Cellulitis isnt always an emergency but it does need treatment. If the area of red, inflamed skin does appear to be expanding but you have no other signs of a worsening infection, you can call your doctor and request an office appointment.

The Healthline FindCare tool can provide options in your area if you dont already have a doctor.

However, if the tender, swollen spot is growing or you show signs of a worsening infection, such as a fever or chills, you should seek emergency medical attention. Your infection may become serious if its not treated quickly.

One way to monitor the inflamed area for growth is to gently draw a circle around the swollen area of skin. A felt-tip marker may be more comfortable than a ball-point ink pen. Then, check the circle and skin two to three hours later. If the redness is beyond the circle you drew, the inflammation and infection are growing.
