The Disease

Economic impact results mostly from productivity losses caused by the disease

Based on a survey of swine veterinarians, the value of productivity losses and increased animal health costs in pigs affected by ileitis in the finishing phase was estimated to be USD4.65 per marketed pig.Based on results from case-control and experimental challenge studies, the value of productivity losses caused by ileitis in the finishing phase ranged from USD5.98 to USD17.34 per marketed pig.The cost of the variation in growth caused by ileitis makes it more difficult to feed and market pigs, this adding to the cost of the disease.The money spent on animal health interventions, such as vaccines, antimicrobials, veterinary services and diagnostics must be weighed against the benefit of reducing the productivity losses caused by ileitis.

L. intracellularis is a gram-negative rod with a sigmoid or curved shape and with a single long flagellum.
History and Etiology of ileitis
Not much is known about the epidemiology of L. Intracellularis.

Epidemiology of ileitis

L. Intracellularis has specific infectious mechanisms, and generally appears in the growing and finishing stages.

Pathogenesis of L. Intracellularis

The symptoms of ileitis in pigs are diverse, and include hemorrhagic or acute, chronic and subclinical.

Clinical signs and forms of ileitis

Diagnosing ileitis involves considering four important factors

Diagnosis of ileitis

Ileitis outbreaks must be treated immediately to reduce losses

Treatment of ileitis

The best preventative option for ileitis depends on the specific farm

Prevention of ileitis

The indications are that nearly all pig populations are susceptible to Lawsonia Intracellularis

Prevalence of ileitis

The ban on antimicrobial growth promoters in the EU affected the kinetics of the infection in different pig diseases

Potential impact of the reduction of antibiotics
