BACTERIAL STRAINS ISOLATED FROM PIGS
First Claim
1. A pharmaceutical composition comprising:
- at least one porcine lactic acid bacterial strain;
wherein the at least one porcine lactic acid bacterial strain is in an amount sufficient to treat or prevent an intestinal disorder in a subject;
wherein said pharmaceutical composition exhibits heat stability when subjected to three cycles of heating, each cycle comprising heating at a temperature of 70°
C. for a period of 15 minutes, wherein said heat stability is determined by an ability of the at least one porcine lactic acid bacterial strain to block adherence of a pathogen to an intestinal pig epithelial cell (IPEC) in vitro; and
wherein said porcine lactic acid bacterial strain is lyophilized and/or said pharmaceutical composition further comprises a pharmaceutically acceptable excipient, diluent, or carrier.

Abstract
A first aspect of the invention relates to a porcine lactic acid bacterial strain, wherein said bacterial strain is characterised by one or more of the following characteristics: (i) the ability to exhibit antimicrobial activity against E. coli; (ii) the ability to exhibit antimicrobial activity against S. enteritidis; (iii) the ability to suppress inflammation in IPEC cells induced by 12-0-tetradecaboylphorbol-13-acetate (PMA); (iv) the ability to block the attachment or invasion of IPEC cells by S. enteritidis; (v) the ability to block the attachment or invasion of IPEC cells by E. coli; (vi) the absence of antibiotic resistance to one or more antibiotics selected from the following: ampicillin; cefotaxime; chloramphenicol; erythromycin; gentamicin; tetracycline; vancomycin; metronizadole; nalidixic acid; and kanamycin; and (vii) the ability to exhibit heat stability when subjected to three cycles of heating, each cycle comprising heating at a temperature of 70° C. for a period of 15 minutes. Further aspects of the invention relate to compositions comprising said bacterial strains, and therapeutic uses of said bacterial strains.
