Provided are a novel polypeptide, a fusion polypeptide comprising the polypeptide, and a use thereof as an antibiotic. More specifically, provided are a novel polypeptide derived from a bacteriophage, a novel fusion polypeptide comprising cecropin A, and an antibiotic against Gram-negative bacteria comprising the polypeptide and/or the fusion polypeptide.

The invention relates to direct-fed microbials for use in E. coli inhibition in animals in combination with enrofloxacin. More particularly, the invention relates to isolated Bacillus strains 9, 57, 71, and 126, and strains having all of the identifying characteristics of these strains, for a use comprising the above-mentioned use.

The present invention relates to antimicrobial peptides derived from Romo1 protein, and specifically, provides various peptides having the amino acid sequence of the α-helix 2 region of the Romo1 protein and an antibacterial composition containing each of the peptides, as a result of confirming that the peptides have antibacterial activity against gram-positive, gram-negative and multidrug-resistant bacteria. The Romo1-derived peptides and variants thereof have better bactericidal capability against various types of bacteria and multidrug-resistant bacteria than existing antibiotics and antibiotic peptides, and have antibacterial activity against various bacteria in blood vessels, and may be provided as substances for the prevention or treatment of a wide range of bacterial infectious diseases. Thus, a composition containing the antimicrobial peptide of the present invention is expected to be used in various applications, including drugs, quasi-drugs, food and feed additives, pesticide and cosmetic additives, to prevent or treat infectious diseases.

Described herein are methods and antibodies useful for reducing, eliminating, or preventing infection with a bacterial population in domestic animals or humans. Also described herein are antigens useful for targeting by heavy chain antibodies and V.sub.HH fragments for reducing a bacterial population in domestic animals or humans.

A process for obtaining extruded animal feed including fibers, especially sugar cane and corn straws, applied in the agricultural and cattle-raising field for the nutrition of ruminants, contributing for higher productive performance (meat or milk) than conventional animal feeds, making use of the non-used sources of fibers for that purpose, with extruded characteristics, as well as for equines, wherein the process follows exactly the same procedure as shown by the patent application, but without the mixture of urea and additives.
