LISTERIA SELECTIVE AGAR (DOUBLE PACK) (PART I)

Description

Listeria Selective Agar was proposed by Feindt for the cultivation of Listeria species from clinical and non-clinical specimens. Obiger and Schonberg reported the superiority of these media to yield Listeria from mix-infected specimens. Bockem?hl reported suppression of Enterococci by combination of selective agents and acridine dyes. The combination of Acriflavin hydrochloride and Nalidixic acid was recommended by Ralovich et al and Kampelmacher and Van Noorle Jansen for the isolation of Listeria. The mix infected specimen is added directly to Listeria Enrichment Broth or subjected to cold enrichment and then cultured on Listeria Selective Agar. Haemolytic forms can be identified by inoculating Blood Agar.
