Microorganisms and methods for treating poultry
An isolated Bacillus strain LSSAO1 is provided. When fed to a bird, this and other Bacillus strains described herein provide benefits to the birds. For example, administration of the one or more Bacillus strain can increase low G+C, gram positive bacteria in the gastrointestinal flora of the bird. These type of bacteria are increased by antibiotics and include beneficial Clostridium . Administration of the one or more Bacillus strain can also inhibit pathogen in the bird, such as E. coli, Salmonella , and Clostridium . These benefits can enhance feed conversion in poultry. Useful combinations of Bacillus strains and methods of using one or more Bacillus strain are also provided.

7. The combination of claim 6 , wherein the two or more isolated Bacillus strains are 22C-P1 ATCC Accession No. PTA-6508, BS27 Accession No. NRRL B-50105, and 2084 Accession No. NRRL B-50013.
8. The combination of claim 6 , wherein the two or more isolated Bacillus strains are LSSAO1 Accession No. NRRL B-50104, 2084 Accession No. NRRL B-50013, and BS27 Accession No. NRRL B-50105.
9. The combination of claim 6 , wherein the two or more isolated Bacillus strains are 15A-P4 ATCC Accession No. PTA-6507, 2084 Accession No. NRRL B-50013, and LSSAO1 Accession No. NRRL B-50104.
10. A method comprising administering an effective amount of isolated Bacillus strain LSSAO1 Accession No. NRRL B-50104 to one or more bird, the administration of the strain providing at least one benefit chosen from increasing low G+C, gram positive bacteria in the gastrointestinal flora of the bird and inhibiting a pathogen chosen from at least one of E. coli, Salmonella , and Clostridium in the bird.
11. The method of claim 10 , wherein the administration of the Bacillus strain provides the benefit chosen from at least one of increases low G+C, gram positive bacteria in the gastrointestinal flora of the bird; improves the feed to gain ratio in the bird; improves feed consumption in the bird; increases the body weight of the bird; decreases mortality in the birds; improves growth of the bird; improves performance of the bird; reduces levels of a pathogen chosen from at least one of E coli, Salmonella , and Clostridium in the bird; controls necrotic enteritis of the bird; improves livability of the bird; improves feed efficiency; decreases cellulitis in the bird; and improves condemnation of the bird.
12. The method of claim 10 , wherein the administration of the Bacillus strain reduces levels of C. perfringes type A in the bird.
13. The method of claim 10 , wherein the administration of the Bacillus strain reduces the level of Salmonella present in the litter of the bird.
14. The method of claim 10 , wherein the administration of the Bacillus strain reduces the level of avian pathogenic E. coli in the bird.
