A new selective medium for the isolation of Listeria monocytogenes

H Gronstol et al. Nord Vet Med. 1977 Oct.

Abstract

A new selective medium for the isolation of Listeria monocytogenes (Lm), is described. The medium contained propolis, nalidixic acid, polymyxin B and rivanol as selective substances. The new medium (propolis-agar) was compared with two other selective media and one nonselective medium. No inhibitory effect was found on the 6 strains of Lm tested, and Lm was easily isolated from a mixture of Lm and contaminating bacteria. The selective effect was better than for the two other selective media tested.
