Enterococci form the natural microflora in the intestine and vagina. They are very resistant to high pH (8.5) and temperatures. They are highly resistant to antibiotics.

Enteroccocus species
Morphology: G + cocci in pairs or chains.
Occurrence: part of the natural microflora in the human gut.
Cultivation: not demanding on cultivation.
Collection of material: for diagnosis, clinical material is collected from gynecological swabs, urine or blood culture.

Diseases[edit | edit source]

Enterococci are among the conditional pathogens. They cause urinary and biliary tract infections, gynecological inflammations, postoperative complications in abdominal surgery and are involved in the development of infectious endocarditis.

Therapy: antibiotics, resistance increases especially in nosocomial strains.

Diagnostic procedure[edit | edit source]


Swabs, urine, blood culture.

  • Microscopy: G+ cocci.
  • Cultivation: BA - gray colonies (possibility of α, β or γ hemolysis), SB - violet-brown colonies.
  • Tests: negative catalase test .
Serological methods

Wall antigen detection (group D).
