Advanced selective plating media

摘要

Selective growth media N4 agars that include a combination of high levels of yeast extract, possibly higher levels of protein, elevated levels of sugar and reduced levels of sodium chloride. The combination of ingredients provides the ability to detect Salmonella spp. and Shigella spp. with almost identical sensitivity while alleviating false-negative and false-positive problems commonly encountered with the presence of Proteus spp. and Citrobacter spp.
