Methods and compositions for the inhibition of growth of infectious
View Patent ↗A method for the prevention and treatment of fungal infections and, therefore, consequent invasive mycosis in mammalian and avian species is described. The invention comprises a combination of β-1,3(4)-endoglucanohydrolase, β-1,3(4)glucan, diatomaceous earth, mineral clay, and glucomannan, which is fed to or consumed by mammalian or avian species in amounts sufficient to inhibit enteric fungal colonization in the gut and consequent mycosis. The invention described may be admixed with feeds or foods, incorporated into pelleted feeds or foods or administered orally to mammalian and avian species.
1. A method for inhibiting growth of an infecting fungal species, comprising formulating a composition comprising a combination of β-glucans, β-1,3(4)-endoglucanohydrolase, diatomaceous earth, a mineral clay, and glucomannan and administering said composition to an animal selected from the group consisting of mammalian and avian species thereby inhibiting growth of an infecting fungal species in the digesta of said animal, thereby reducing susceptibility of the animal to a mycotic colonization of the digestive tract and invasive mycoses.
2. The method of claim 1 , wherein the infecting fungal species includes a fungal genera selected from the group consisting of Aspergillus, Aureobasidium, Candida, Eupenicillium, Eurotium, Fusarium, Mucor, Penicillium , and Rachiborskiomyces.
3. The method of claim 1 , wherein the infecting fungal species is a member of the Aspergillus genera.
4. The method of claim 1 , wherein the infecting fungal species is Aspergillus fumigatus.
5. The method of claim 1 , wherein the mineral clay is selected from the group consisting of montmorillonite, bentonite, aluminosilicate, zeolite clays, and mixtures thereof.
6. The method of claim 1 , further including producing the β-1,3(4)-endoglucanohydrolase from submerged fermentation of Trichoderma longibrachiatum.
7. The method of claim 1 , further including deriving the β-glucans and glucomannan from boiling and enzyme autolysis of gram positive yeast cell walls from the genera of Saccharomyces.
8. The method of claim 1 , further including deriving the β-glucans and glucomannan from boiling and enzyme autolysis of gram positive yeast cell walls from Saccharomyces cerevisiae.
9. The method of claim 1 , further including calcining the diatomaceous earth at a minimum temperature of 900° C.
10. The method of claim 1 , wherein the composition comprises between 15% and 40% diatomaceous earth, between 50% and 81% mineral clay, between 1.0% and 5.0% β-glucans, between 0.05% and 3.0% β-1,3(4)-endoglucanohydrolase and between 1% and 8.0% glucomannan.
11. The method of claim 1 , wherein the composition comprises between 20% and 30% diatomaceous earth, between 60% and 75% mineral clay, between 1.0% and 3.5% β-glucans, between 0.1% and 3.0% β-1,3(4)-endoglucanohydrolase and between 1.0% and 6.0% glucomannan.
12. The method of claim 1 , further comprising admixing the composition into foods or animal feedstuffs in a concentration of between 0.0125% and 5% by weight of the composition based on the total weight of the foods or feedstuffs for the purpose of inhibiting fungal growth in feed, food or digesta.
13. The method of claim 1 , further comprising admixing the composition into a food or feedstuff, and wherein said administering includes feeding said food or feedstuff to domestic livestock.
14. The method of claim 1 , further comprising admixing the composition into a food or feedstuff, and wherein said administering includes feeding said food or feedstuff to ruminant livestock.
15. The method of claim 1 , wherein said administering of the composition reduces mycotic colonization of the gastrointestinal tract of said animal.
