Check your pigs for lawsonia


Lawsonia intracellularis is an unwelcome guest in your swine barn because this bacterium causes porcine intestinal adenomathosis (PIA), intestinal problems that can lead to diarrhea or even death. The bacteria is prevalent in many piggeries.

Two test methods

There are different variants of the disease, namely acute, chronic, and subclinical. The acute form can be recognized simply from black manure or pigs turned pale. The chronic variant is characterized by diarrhea and thickening of the last part of the small intestine. The subclinical infection shows no obvious symptoms. An outbreak of any of the three forms has a major impact on the results of your piggery. Tight barn management and testing are therefore important.

Lavetan tests with the ELISA technique and with a real-time PCR method. The ELISA technique allows us to determine the antibodies. The real-time PCR technique allows us to detect the bacteria in infected pigs.

What is lawsonia in pigs?

Lawsonia intracellularis causes ileitis (intestinal wall inflammation) in pigs. The disease is present in a large number of piggeries. Pigs that previously had little contact with this pathogen appear to be especially susceptible to the acute variant at high rates of infection. How the chronic and subclinical forms occur remains unknown.
