The invention relates to a composition for the treatment and / or prevention of infection by gastrointestinal pathogens, in particular Helicobacter pylori and / or a disease associated with infection by said gastrointestinal pathogen in mammals.

The invention relates to a composition for the treatment and / or prevention of infection by gastrointestinal pathogens, in particular Helicobacter pylori and / or a disease associated with infection by said gastrointestinal pathogen in mammals.

The invention belongs to the technical field of biology and provides an anti-enzymolysis antibacterial peptide II4II and a preparation method and application thereof. The amino acid sequence of the antibacterial peptide II4II is shown in SEQ ID No. 1. The preparation method comprises the following steps of reasonably arranging amino acids in the sequence based on specific restriction enzyme cutting sites of trypsin, chymotrypsin and pepsin and basic characteristics of the antibacterial peptide, and selecting Ile as a hydrophobic amino acid to obtain the antibacterial peptide II4II. The invention further provides application of the antibacterial peptide II4II in preparation of medicines for treating gastrointestinal tract infection diseases caused by gram-negative bacteria or / and gram-positive bacteria. The antibacterial peptide II4II has a relatively good inhibition effect on multiple bacteria, is relatively low in hemolytic activity, has a treatment index of 80.63, has relatively goodanti-enzymolysis property, is kept unchanged in antibacterial activity after being treated by trypsin, chymotrypsin or pepsin, and has application potential as an antibiotic substitute.

The invention relates to a composition for the treatment and / or prevention of infection by gastrointestinal pathogens, in particular Helicobacter pylori and / or a disease associated with infection by said gastrointestinal pathogen in mammals. The composition comprises a pea protein hydrolysate, intact pea protein and / or camel milk protein hydrolysate.

The present invention relates to the use of oligosaccharides derived from arabinoxylan for use in the prevention and treatment of gastrointestinal infection. More particularly the invention provides a method for preventing or reducing the gastrointestinal infection of a animal or human being with bacteria associated with gastroenteritis through the supplementation of their diets with the said oligosaccharides.

Compositions including a non-pathogenic lactic acid-producing bacteria, such as a Bacillus species, spores or an extracellular product of B. coagulans, formulated for oral administration to the intestinal tract for inhibiting bacterial gastrointestinal infections are described. Methods and systems using the compositions for treating gastrointestinal infections, particularly sudden infant death syndrome (SIDS) are also disclosed.

The present invention provides methods and compositions for controlling gastrointestinal parasitic infections in animals. More specifically, the invention involves the use of sericea lespedeza (Lespedeza cuneata), commonly referred to as Chinese bush clover, in the diet of animals to control nematodal gastrointestinal infections.

Methods are disclosed for the prevention and / or treatment of certain gastrointestinal (GI) diseases, such as Johne's Diseases (JD) in animals and Crohn's Disease (CD) in human. Administration of certain probiotic bacteria, such as lactic acid producing bacteria, to animals helps inhibit GI infection by Mycobacterium avium subsp. paratuberculosis (MAP). MAP is the primary pathogenic agent suspected of causing various inflammatory bowel diseases in cattle or humans.

The present invention relates to a composition comprising IgY antibodies against at least two different fungi, the use of the composition for the preparation of a pharmaceutical especially for prophylaxis and / or therapy of all kinds of fungal infections, such as conditions caused by organisms belonging to the Candida genus or Aspergillus genus, especially of fungi that are less sensitive to antimycotica and a diagnotstic method using the IgY antibodies. Further it relates to immunisation of birds with a combination of at least two different species of fungi to the Candida genus or Aspergillus genus and a diagnostic method for fungi. It also relates to relates to a novel method for treatment and / or prophylaxis of fungal infections, especially infections by fungi which have lowered sensitivity or resistance to antimycotics. The method is both safe and effective. This is achieved by using IgY directed against fungi, in particular against Candida species, which have a lowered sensitivity or resistance against antimycotics. The specific IgY has been obtained by hyper immunising birds with one or several fungi as antigen in order to stimulate the production of immune globulins (IgY) against such fungi. The present invention also relates to a pharmaceutical product from eggs of birds containing immune globulin or a fragment thereof, which can be combined with other preparations, nutritients or pharmaceuticals for simultaneous, separate or sequential use in the prophylaxis or therapy of gastrointestinal infections in newborn infants.

Described herein is secretory IgA isolated from the intestinal luminal fluid and intestinal mucosal of animals such as pigs and cows. Also included are methods of isolating secretory IgA. The secretory IgA is useful in food compositions such as animal and human food compositions as well as pharmaceutical compositions to increase growth rate, improve feed efficiency, reduce gastrointestinal inflammation, reduce a risk of gastrointestinal infection in the animal, or a combination thereof.
