Staphylococcus aureus Infections


Staphylococcus aureus infection is a medical condition caused by the Staphylococcus aureus bacteria.  These bacteria are usually found on the skin and mucous membranes of humans and animals, and while generally harmless, they can cause various infections when they enter the body through wounds, cuts, or other openings.  Staphylococcus aureus is an important pathogen that can cause mild to severe and even life-threatening conditions.




Staphylococcus aureus is a versatile bacterium that can cause a variety of infections ranging from mild to severe.  Some common types of S. aureus infection include:


  1. Skin and soft tissue infections:

Abscesses (abscesses): Painful, pus-filled nodules that appear on hair follicles.

Abscess: An accumulation of pus in a cavity, usually with drainage.

Cellulite: Inflammation of the skin and surrounding tissues, causing redness and warmth.

Impetigo: A contagious skin infection characterized by blisters and crusts.

  1. Respiratory Infections:

Staph infection: A pneumonia that causes fever, cough, and difficulty breathing, especially in people with weakened immune systems.


  1. Bloodstream Infections (Bacteremia):

Bacteria entering the bloodstream can lead to serious conditions such as sepsis with symptoms such as high fever, rapid heartbeat and confusion.


  1. Bone And Joint Infections:

Osteomyelitis: A bone infection causes pain, swelling, and fever.

Septic arthritis: An infection of the joints that causes pain, swelling, and limited range of motion.

It’s important to remember that S. aureus infections can sometimes progress quickly and cause serious complications, especially in people with weakened immune systems or underlying health conditions.  If you suspect that you have an S. aureus infection or are experiencing symptoms that are worrying you, it is recommended that you seek medical attention immediately.  In addition, good hygiene practices, wound care, and infection prevention measures can help reduce the risk of S. aureus infection.


Treatment of Staphylococcus aureus infection depends on the type and severity of the infection and the antibiotic sensitivity of the respective bacterial strain.  Staphylococcus aureus is known to develop resistance to antibiotics, including methicillin-resistant Staphylococcus aureus (MRSA), which complicates treatment options.  Here are some general guidelines for treating Staphylococcus aureus infections:


  1. Antibiotica: Antibiotica vormen de steunpilaar van de behandeling van S. aureus-infecties. De keuze van het antibioticum hangt af van factoren zoals het type infectie, de medische geschiedenis van de patiënt en lokale patronen van antibioticaresistentie. Veelgebruikte antibiotica zijn:
  • meticilline of oxacilline (indien stressgevoelig).
  • Vancomycine (gebruikt voor de behandeling van MRSA en ernstige infecties).
  • Jij bent clindamycine.
  • Linsold
  • Trimethoprim-sulfamethoxazol (Bactrim).


  1. Drainage en debridement: In geval van huid- en weke deleninfecties kan chirurgische drainage van het abces nodig zijn om de pus en het geïnfecteerde materiaal af te voeren. Helpt de effectiviteit van antibiotica te vergroten en genezing te bevorderen.


  1. Ondersteunende zorg: Afhankelijk van de ernst van de infectie kan ondersteunende zorg nodig zijn om de symptomen te beheersen en vitale functies te behouden. Dit kan intraveneuze vloeistoffen, pijnbestrijding en zuurstoftherapie omvatten.


  1. Monitoring en follow-up: Het is noodzakelijk om de toestand van de patiënt en de reactie op de behandeling regelmatig te controleren. Het behandelplan moet mogelijk worden aangepast als de infectie niet reageert zoals verwacht of als deze erger wordt.


  1. Preventie en infectiebeheersing: Het voorkomen van de verspreiding van S. aureus-infectie is erg belangrijk, vooral in de gezondheidszorg. Dit omvat strikte infectiebeheersingspraktijken, goede handhygiëne en isolatievoorzorgsmaatregelen voor patiënten met een actieve infectie.


  1. Vermijd overmatig gebruik van antibiotica: Vanwege het risico op antibioticaresistentie is het belangrijk om antibiotica verstandig te gebruiken en de aanbevolen behandelingsrichtlijnen te volgen.


  1. Voorzorgsmaatregelen voor MRSA: Voor MRSA-infecties kunnen aanvullende maatregelen nodig zijn, zoals dekolonisatieprotocollen, om de overdracht van MRSA in de neusgangen en de huid te verminderen.


Het is belangrijk op te merken dat het niet wordt aanbevolen om een ​​S. aureus-infectie zelf te behandelen met antibiotica.  Als u vermoedt dat u een Staphylococcus aureus-infectie heeft, is het belangrijk om medische hulp in te roepen.  Uw zorgverlener bepaalt de juiste behandelingskuur op basis van uw specifieke situatie.


In de afgelopen jaren heeft de opkomst van antibioticaresistente Staphylococcus aureus-stammen het belang benadrukt van infectiepreventie- en controlemaatregelen, verantwoord gebruik van antibiotica en de ontwikkeling van nieuwe therapeutische strategieën om deze uitdagende infecties te bestrijden.
