Is necrotizing fasciitis associated with Streptococcus?

There are many types of bacteria that can cause the “flesh-eating disease” called necrotizing fasciitis. Public health experts believe group A Streptococcus (group A strep) are the most common cause of necrotizing fasciitis.

Does Streptococcus aureus cause necrotizing fasciitis?

Background. Necrotizing fasciitis is a life-threatening infection requiring urgent surgical and medical therapy. Staphylococcus aureus has been a very uncommon cause of necrotizing fasciitis, but we have recently noted an alarming number of these infections caused by community-associated methicillin-resistant S.

What does Streptococcus anginosus cause?

Streptococci of the anginosus group can reside commensally in the human oral cavity but have a certain propensity to cause pharyngitis, bacteremia, and serious purulent infections in the deep neck and soft tissue and in internal organs such as the brain, lung, and liver (17–25).

How does strep A turn into necrotizing fasciitis?

Strep is the bacteria that causes strep throat. However, when it penetrates into the body, it can cause necrotizing fasciitis. When Group A Strep causes NF, it can occur together with Streptococcal Toxic Shock Syndrome (STSS), which accelerates the speed and deadliness of the infection.

Can Group B strep cause necrotizing fasciitis?

To our knowledge, however, group B streptococci (Streptococcus agalactiae) have been reported to cause necrotizing fasciitis in only 4 instances (2 involving neonates) over the past 4 decades.

Does Streptococcus pyogenes cause necrotizing fasciitis?

Streptococcus pyogenes is a major cause of necrotizing fasciitis, a life-threatening subcutaneous soft-tissue infection. At the host infection site, the local environment and interactions between the host and bacteria have effects on bacterial gene expression profiles, while the gene expression pattern of S.

Is Streptococcus anginosus serious?

Bacteria belonging to the Streptococcus anginosus group (Streptococcus intermedius, Streptococcus constellatus and Streptococcus anginosus) are capable of causing serious pyogenic infections, with a tendency for abscess formation.

How do you get strep anginosus?

With S. anginosus blood stream infections (bacteremia) it has been widely reported that the source is often from an abscess. In one series of 51 cases of Strep milleri group bacteremia, 6 were associated with abscesses. Pyogenic liver abscess is associated with S.

What happens if strep gets into your bloodstream?

Blood infections: The strep bacteria can also get into your bloodstream, where they don’t normally live. This is called “bacteremia.” If the strep bacteria release toxins in multiple organs, it can create another rare, life-threatening condition called “streptococcal toxic shock syndrome” that can cause organ failure.

How does streptococcus bacteria enter the body?

These bacteria are spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin. The risk of spreading the infection is highest when a person is ill, such as when people have “strep throat” or an infected wound.

Can you survive necrotizing fasciitis?

Conclusions: Patients who survive an episode of necrotizing fasciitis are at continued risk for premature death; many of these deaths were due to infectious causes such as pneumonia, cholecystitis, urinary tract infections, and sepsis.

What does Streptococcus pyogenes do to skin?

S. pyogenes cause a variety of skin and soft-tissue infections, including frequent and less complicated manifestations of impetigo, erysipelas, and mild cellulitis and rare but life-threatening infections of deep tissue or muscle (eg, necrotizing fasciitis and myositis).

How common is S. anginosus?

The Streptococcus milleri group of bacteria (Streptococcus anginosus, Streptococcus constellatus and Streptococcus intermedius) is part of the intestinal flora in 20–50% of the population (Hardwick et al, 2000) and is now recognised as a significant pathogen associated with abdominal, thoracic and hepatic sepsis.

Can Streptococcus be fatal?

Streptococcal toxic shock syndrome (STSS) is a rare, but serious bacterial infection. STSS can develop very quickly into low blood pressure, multiple organ failure, and even death. Good wound care, hand hygiene, and cough etiquette are important for preventing this serious and often deadly disease.

Is Streptococcus the same as sepsis?

Group A Streptococcus, also called group A strep, is a bacterium that can cause many different infections. These may cause sepsis. Sometimes incorrectly called blood poisoning, sepsis is the body’s often deadly response to infection.

Where do you get Streptococcus bacteria?

Streptococcal bacteria are contagious. They can spread through droplets when someone with the infection coughs or sneezes, or through shared food or drinks. You can also pick up the bacteria from a doorknob or other surface and transfer them to your nose, mouth or eyes.
