Novel epidemic clones of Listeria monocytogenes, United States, 2011

Emerg Infect Dis. 2013 Jan;19(1):147-50. doi: 10.3201/eid1901.121167.

Abstract

We identified a novel serotype 1/2a outbreak strain and 2 novel epidemic clones of Listeria monocytogenes while investigating a foodborne outbreak of listeriosis associated with consumption of cantaloupe during 2011 in the United States. Comparative analyses of strains worldwide are essential to identification of novel outbreak strains and epidemic clones.
