Description

Enterohaemolysin Agar Base is a particularly suitable medium to highlight the enterohaemolysina, allowing the identification of enterohaemorrhagic E.coli (EHEC), even in low concentration and/or in the presence of abundant flora contaminant.

Escherichia coli is a facultative anaerobic species, predominant in the human and animal intestine. A group of E.coli, however, is now emerging as a pathogen in diarrheal forms. The group includes: enterotoxigenic E.coli (ETEC), enteropathogenic E.coli (EPEC), enterohemorrhagic E.coli (EHEC) and enteroinvasive E.coli (EIEC).

Among these, great importance is enterohemorrhagic E.coli (EHEC), which may cause bloody diarrhea, through the consumption of water and/or food (milk, vegetable sprouts, minced meat) contaminated by this species.

EHEC are characterized by the production of verotoxin or Shiga toxin (Stx). Studies on clinical material, show that about 90% of EHEC, including all O157 EHEC, have the formation of enterohaemolysina as a phenotypic characteristic.
