8.3.1 What are the general conclusions from the trials in Asia and Australia and what are the take home messages?
Ileitis is in Asia and Australia present in almost all farms and with the same problems as in other parts of the world.
In Australia, which has been able to keep some of the important swine diseases out due to its remote and isolated location, Ileitis is a major problem. This raises the interest for epidemiological studies on the transmission of Lawsonia intracellularis. Enterisol® Ileitis is the first registered attenuated live vaccine for pigs in Australia, which demonstrates the safety of the vaccine.
Fast growing swine producing countries like China; have also published the presence of Ileitis in their herds demonstrating similar clinical symptoms as in other countries. These findings once more support the generally accepted idea of the monotypic character of Lawsonia intracellularis.
The results in the Philippines, Japan and Australia with Enterisol® Ileitis are in-line with the results in Europe and the America’s. Therefore, the economical return of vaccination can be expected at a similar range as seen in Europe.
