Abstract

This study investigated the exposure to Lawsonia intracellularis in wild birds, mice, rabbits, raccoons, coyotes and squirrels, and feral cats and pigs on 10 farms with confirmed equine proliferative enteropathy (EPE). Serum samples from all resident foals (417 samples) as well as fecal (461) and serum (106) samples from wild and feral animals were collected for serological and molecular detection of L. intracellularis following the diagnosis of EPE in index cases. A total of three cats from two farms, three mice from two farms and eight cottontail rabbits from one farm had evidence of prior exposure to L. intracellularis. These animals may be an indicator of environmental exposure or may be actively involved in the transmission of L. intracellularis to foals by acting as a potential reservoir/amplifier host.
