| Abstract: | A selective-enrichment procedure (SEP) was developed to isolate Listeria monocytogenes from fecal and biologic specimens. This procedure was compared with direct plating with McBride listeria agar and 2-, 4-, and 8-week cold-enrichment procedures in recovering L. monocytogenes from mouse fecal, liver, and brain specimens. Although the SEP occasionally did not isolate the organism from specimens proved positive by the other procedures, the SEP isolated L. monocytogenes from about two and five times as many specimens as the cold-enrichment and direct-plating procedures, respectively. |
