We are seeing a statistically significant increase in positive Lawsonia PCRs submitted to the UKVDL as compared to recent years.
Lawsonia intracellularis is an obligate intracellular agent of proliferative enteropathies in horses, pigs, sheep, deer and other species worldwide. The source of the infection for horses is not well characterized. It affects mostly weanling foals (3-13 months) and presents with pyrexia, lethargy, diarrhea, colic, weight loss and hyproteinemia. Thickened small intestines can be visualized on ultrasonography. A diagnosis can be confirmed by PCR on feces. Because the epidemiology of the disease is not well understood, methods of prevention have not been worked out.UC Davis is testing a swine vaccine for safety and efficacy.
The UKVDL can assist you in the diagnosis of a Lawsonia infection.
