RECOMBINANT MICROORGANISMS, METHODS FOR PREPARING VACCINE STRAINS, ANTIGENS, AND VECTOR VACCINE COMPOSITIONS OF SAME, USES THEREOF, AND RELATED ANTIBODIES, DIAGNOSTIC KIT, AND TREATMENT AND/OR PROPHYLACTIC METHODS
The present invention provides live recombinant microorganisms such as prokaryote organisms, particularly enterobacteria, preferably Salmonella enterica, containing SEQ. ID. no. 1 and SEQ. ID. no. 2 capable of expressing VapG and/or VapA/VapG lipoproteins (SEQ. ID. no. 3 and SEQ. ID. no. 4), optionally in combination with other active ingredients, methods for preparing vaccine strains, antigens (SEQ. ID. no. 3 and SEQ. ID. no. 4) and vaccine compositions, preferably vectored vaccines. Additionally, the present patent application relates to the use of the vaccine vectors in the preparation of pharmaceutical compositions, particularly vaccines indicated for the prevention and/or treatment of infections by Rhodococcus equi, its antibodies and/or antisera, diagnostic kits and methods for the prophylaxis and/or treatment of infections by R. equi.
