Abstract: | Lawsonia intracellularis is a cause of protein‐losing enteropathy in weanling foals commonly causing signs including diarrhoea, oedema and unthrifty appearance. It has previously been reported as sporadic cases throughout the USA, Canada and Europe. Only recently have outbreaks on a single farm location been reported. The cases reported here are an example of multiple foals on a single farm testing serologically positive for L. intracellularis. These foals ranged in severity from asymptomatic to severely hypoproteinaemic and septic; however, none of the foals ever displayed diarrhoea, which is the most common presenting sign of this disease process. |
