Hektoen Enteric Agar is a culture medium used to differentiate Salmonella (which forms a black precipitate due to H2S production) from Shigella (which does not).
El agar Hektoen Enteric es un medio de cultivo diferencial utilizado para diferenciar Salmonella y Shigella. Salmonella produce sulfuro de hidrógeno, que forma un precipitado negro en el agar, mientras que Shigella no lo produce y las colonias permanecen verdes.
