Hektoen Enteric Agar

Hektoen Enteric Agar (HE) is a selective and differential medium designed to isolate and differentiate members of the species Salmonella and Shigella from other Enterobacteriaceae. Bile salts and the dyes bromthymol blue and acid fuchsin inihibit the growth of most Gram positive organisms.

They are not transmitted from animal contact as for Salmonella. When grown on Hektoen enteric agar colonies will appear as green colonies and are distinguishable from Salmonella because they do not produce hydrogen sulfide in the presence of thiosulfate. The infectious dose is low and can cause disease with very few cells.

01/01/2003 ÿú Hektoen enteric (HE) agar is a medium for the isolation of Shigella and Salmonella.It relies on the use of bile salts for selective inhibition and two indicator systems: (1) bromothymol blue and acid fuchsin as indicators of carbohydrate dissimilation and (2) ferric iron as an indicator of the formation of hydrogen sulfide from thiosulfate.

INSTRUCTIONS FOR USE ? READY-TO-USE PLATED MEDIA PA-254009.08 Rev.: Mar 2013 PA-254009.08 - 1 - BD Hektoen Enteric Agar (HE Agar ) INTENDED USE BD Hektoen Enteric Agar is a moderately selective and differential medium for the isolation and cultivation of gram-negative enteric micro-organisms, especially for the isolation of Shigella and Salmonella species from fecal specimens.

Hektoen enteric agar Hektoen Enteric Agar (HEA) merupakan media selektif-diferensial. Media ini tergolong selektif karena terdiri dari bile salt yang berguna untuk menghambat pertumbuhan bakteri gram positif dan beberapa bakteri gram negatif, sehingga diharapkan bakteri yang tumbuh hanya Salmonella.
