LAWSONIA INTRACELLULARIS BACTERIUM OF A NOVEL SEROTYPE, VACCINE BASED ON THAT BACTERIUM, ANTIBODIES SUITABLE FOR DIAGNOSING THE NOVEL LAWSONIA INTRACELLULARIS SEROTYPE AND HYBRIDOMAS FOR PRODUCING THE SAID ANTIBODIES

摘要

This invention pertains to Lawsonia intracellularis bacterium of a serotype which is reactive with monoclonal antibody INT-LIC-02-02 as produced by hybridoma INT-LIC- 02-02 deposited with the Collection Nationale de Cultures de Micro-organismes of the lnstitut Pasteur at Paris France under nr. CNCM I-4049, but which is not reactive with antibody INT-LIC-01-28 as produced by hybridoma INT-LIC-01-28 deposited with the Collection Nationale de Cultures de Micro-organismes of the lnstitut Pasteur at Paris France under nr. CNCM I -4048. The invention also pertains to vaccines for protection against an infection with Lawsonia intracellularis based on those novel bacteria, antibodies suitable for diagnosing the novel Lawsonia intracellularis serotype and hybridomas for producing the said antibodies.
