toms, including diarrhea, dehydration, lethargy, intermittent colic, loss of condition, a rough haircoat, fever, and a potbellied appearance.
The edema Linda noted on her yearling usually appears on the ventral midline of the abdomen rather than the face. Mucosal surfaces in the intestinal tract may appear thickened, eroded or ulcerated – and the ulcers, if severe, can some- times lead to intestinal perforation and peritonitis.
with no symptoms, but full-blown disease can be triggered when stress factors such as overcrowd- ing, a change in diet, or transport comes into the picture.

So where does Lawsonia come from? Environmental contamination with feces from infected animals seems to be the most likely route of transmission to horses, and it’s easy enough to accomplish in the average barn in which rodents are present. Infectious disease specialists have not yet  gured out how long Lawsonia can remain contagious in the outside environment, however.
Two tests are currently available for L. intracellularis: a fecal PCR test which detects the bacterial DNA, and a blood enzyme-linked test which measures the concentration of antibodies to the bacteria. Both return fairly rapid results. The usual treatment for mild cases is on-farm administration of erythromycin, sometimes combined with rifampin, or tetracycline. More severe cases which require hospitalization may need plasma transfusions, anti-ulcer meds, intravenous  uids, and sometimes IV feeding.
Once the bacteria is ingested, it targets intestinal epithelial cells and multiplies inside the digestive tract. Most animals who pick up the bacteria just harbour a subclinical infection
Says Staemp i, “The source of bacteria and mode of transmission are unknown, and it remains unclear why some foals are affected and not others. The disease is well-studied in pigs and is commonly seen in even the best health-man- aged pig farms all over the world. Research needs to focus on identifying carriers and reservoirs of L. intracellularis on horse farms.”

A live vaccine has recently become available for pigs, but there is no vaccine for
horses as of yet. That may need to change if the incidence of this insidious infection continues to rise.
