Abstract: | The selective media PALCAM and L-PALCAMY were evaluated for their potential ability to detect Listeria monocytogenes in faeces. Recovery on PALCAM was almost total, and similar at 30°C and 35°C with or without CO2 incubation. Warm enrichment in L-PALCAMY was necessary in order to detect low numbers (<102/ml faeces). Faeces in excess of 0.25 ml/10 ml L-PALCAMY was inhibitory. The results point to L-PALCAMY and PALCAM as an epidemiological tool. |
