What three types of bacteria can cause necrotizing fasciitis?
Necrotizing fasciitis is commonly caused by group A streptococcus (GAS) bacteria. That’s the same type of bacteria that causes strep throat. But, several types of bacteria, such as staphylococcus and others, have also been linked to the disease.
Which disease is caused by Streptococcus pyogenes?
Life-threatening infections caused by Streptococcus pyogenes (group A streptococcus) include scarlet fever, bacteremia, pneumonia, necrotizing fasciitis, myonecrosis and Streptococcal Toxic Shock Syndrome (StrepTSS).
Where does the bacteria that causes necrotizing fasciitis come from?
There are many strains of bacteria that can cause the flesh-eating disease known as necrotizing fasciitis, but most cases are caused by a bacteria called group A strep, or Streptococcus pyogenes. More common infections with group A strep are not only strep throat, but also a skin infection called impetigo.
Does Streptococcus pneumoniae cause necrotizing fasciitis?
Necrotizing fasciitis due to Streptococcus pneumoniae is a rare and grave condition, and only a few cases have been reported. Suggested risk factors include minor trauma, systemic lupus erythematosus, immunosuppression secondary to medication, use of intramuscular anti-inflammatories and alcoholism.
What is necrotising fasciitis?
Necrotising fasciitis, also known as the “flesh-eating disease”, is a rare and life-threatening infection that can happen if a wound gets infected. It needs to be treated in hospital straight away.
Where is necrotizing fasciitis most commonly found?
The most common body sites where necrotizing fasciitis tends to occur are the extremities (arms, hands, feet and legs). However, necrotizing fasciitis can also occur in the head, neck and groin regions depending on the circumstances and risk factors.
Does Streptococcus pyogenes cause gas gangrene?
Gas gangrene is most often caused by bacteria called Clostridium perfringens. It also can be caused by group A streptococcus, Staphylococcus aureus, and Vibrio vulnificus.
What is the transmission of necrotizing fasciitis?
The infection often begins like most others – through a cut or a scrape. However, unlike other infections, this one spreads very quickly as the bacteria do their damage. They grow and release a harmful substance that destroys surrounding tissue and can enter the blood stream.
What are the two types of necrotizing fasciitis?
The main types of necrotising fasciitis are: Type I (polymicrobial ie, more than one bacteria involved) Type II (due to haemolytic group A streptococcus, and/or staphylococci including methicillin-resistant strains/MRSA)
What is another name for Streptococcus pyogenes?
Streptococcus pyogenes, also known as group A streptococcus (GAS), is most commonly associated with mild, self-resolving infections of the skin and oropharynx.
