BCP agar
Isolation of common microorganisms
BCP agar (Lactose agar with Bromcresol purple) is an isolation and differentiation medium for the development of all organisms commonly found in specimens of various origin.
It also differentiates lactose-fermenting organisms from non-fermenting organisms.
Lactose (+) organisms produce yellow colonies by acidification of the medium.
Non-fermenting organisms produce blue or colourless colonies.

Eosin-methylene blue agar
Isolation of Enterobacteriaceae
Eosin-methylene blue agar is a selective isolation and differentiation medium for the detection of Enterobacteriaceae.
It enables lactose- and/or sucrose-fermenting microorganisms to be differentiated from non-fermenting microorganisms.
Eosin-methylene blue agar is used to detect enterobacteria in stools, urine or other biological specimens.
Lactose (+) and/or sucrose (+) microorganisms produce dark purple colonies by acidification of the medium, which may be accompanied by a metallic sheen.
Non-fermenting microorganisms produce colourless or slightly pinkish colonies.
The presence of 2 stains inhibits the growth of Gram-positive bacteria.

Mac Conkey agar
Selective isolation of Enterobacteriaceae and Escherichia coli
MacConkey agar with crystal violet is a selective isolation and differentiation medium for the detection of
Enterobacteriaceae in specimens of various origins.
This medium is specially designed to detect the fermentation of lactose through a colour change to neutral red.
- lactoses (+) colonies: pink to red, sometimes surrounded by a halo of precipitated bile salts.
- lactose (-) colonies: colourless or slightly beige.
The selectivity for Gram-positive bacteria is provided by bile salts and crystal violet.

Drigalski agar
Selective isolation of Enterobacteriaceae and other Gram-negative bacteria
Drigalski agar is a selective isolation and differentiation medium used to identify Enterobacteriaceae and other Gram-negative bacteria in feces, urine or other biological specimens.
Microorganisms that ferment lactose form yellow or yellowish-green colonies; the others produce blue, green, or bluish-green colonies.
The presence of sodium deoxycholate and crystal violet inhibits the growth of Gram-positive.

SS agar
Selective isolation of Salmonella and Shigella
SS agar is a selective isolation and differentiation medium recommended for the detection of Salmonella and Shigella species.
The medium is inoculated from stool specimens, suspension of stools or an enrichment broth.
The medium detects lactose-fermenting and thiosulfate-reducing (production of H2S) colonies.
Lactose-fermenting microorganisms produce pink colonies, the others give colourless colonies.
H2S-producing microorganisms produce colonies with a black centre.
- Colonies of Salmonella are colourless to pale yellow, with or without a black centre.
- Colonies of Shigella are colourless to pale pink or orange-coloured without a black centre.
The inhibition of Gram-positive micro-organisms is obtained by a mixture of bile salts and stains.

Hektoen agar
Selective isolation of Salmonella and Shigella
Hektoen agar is a selective isolation and differentiation medium recommended for the detection of Salmonella and Shigella species.
The medium is inoculated from stool specimens, suspension of stools or an enrichment broth.
Microorganisms that ferment one of the three sugars in the medium form yellow or yellowish-pink colonies; the others produce green to bluish-green colonies.
H2S-producing microorganisms form colonies with a black centre.
- Colonies of Salmonella are green to bluish-green, with or without a black centre.
- Colonies of Shigella are green to bluish-green without a black centre.
Inhibition of Gram-positive microorganisms is obtained by a mixture of bile salts and stains.

CLED agar
Isolation of urinary tract micro-organisms
CLED agar (Cystine Lactose Electrolyte Deficient) is especially useful for the isolation of urinary tract micro-organisms.
It also enables the differentiation of lactose-fermenting and non lactose-fermenting bacteria (bromothymol blue indicator).
- Lactose (+) bacteria produce pale yellow to yellow colonies by acidification of the medium.
- Non-lactose fermenting bacteria produce green, blue or colourless colonies.
The composition of the medium (weak electrolyte content) prevents the swarming of Proteus.
The new CLED formula provides real advantages in terms of larger colony size, improvement of Lactose character reading, and better colony differentiation.

Mannitol Salt 2 agar
Selective isolation of staphylococci
Mannitol Salt 2 agar is intended for the selective isolation of staphylococci in human specimens and orientation of identification of S. aureus.
The new formula has increased nutrient capacity, sensitivity of detection and specificity.
Micro-organisms which ferment mannitol produce yellow colonies.
This characteristic is a criterion for orienting identification of Staphylococcus aureus.
The high content of sodium chloride in the medium limits the growth of certain bacteria other than Staphylococcus.
