Abstract

Listeria monocytogenes (LM) is a bacterial pathogen that causes late-term abortions in cattle, and definitive diagnosis and point-source determination may be challenging. In 2014, a diagnostic work-up of listerial abortions was initiated by a novel sample collection protocol. To determine the source(s) of the outbreak, LM strains isolated from cases and their environment were subjected to whole-genome sequencing and compared.
