The present invention generally relates to the field of preventing and/or treating inflammatory and infectious disorders, in particular by boosting the endogenous antimicrobial defences. One embodiment of the present invention is the use of non-replicating L. johnsonii La1 NCC533 (deposit number CNCM I-1225) for use in the treatment or prevention of disorders related to the immune system including infections.
1. A method for treatment of a disorder selected from the group consisting of Crohn's disease, infectious diarrhea, antibiotic-associated diarrhea, gingivitis, and combinations thereof, the method comprising administering a composition comprising Lactobacillus johnsonii La1 (NCC533, deposit number CNCM I-1225) to an individual having the disorder, wherein the L. johnsonii La1 is rendered non-replicating by a heat treatment at a temperature of 110° C. to 140° C. for 1-30 seconds.
2. The method in accordance with claim 1 , wherein the heat treatment is carried out for at least 10 seconds.
3. The method in accordance with claim 1 , wherein the composition is administered to the individual in an amount that provides 10 4 to 10 12 cfu of the L. johnsonii La1 (NCC533, deposit number CNCM 1-1225) per day.
4. The method in accordance with claim 1 , wherein the composition is administered to the individual in an amount that provides about 0.005 mg 1000 mg of the L. johnsonii La1 (NCC533, deposit number CNCM 1-1225) per day.
5. The method in accordance with claim 1 , wherein the composition is selected from the group consisting of food compositions, food products, drinks, formulas for complete nutrition, nutritional supplements, nutraceuticals, food additives, pharmaceutical compositions, cosmetical compositions, topical compositions, and medicaments.
6. The method in accordance with claim 1 , wherein the composition increases endogenous hBD1 expression.
7. The method of claim 1 , wherein the heat treatment is at 120° C. for 15 seconds.
8. The method of claim 1 , wherein the composition increases endogenous antimicrobial defences.
9. A method to increase the effectiveness of L. johnsonii La1 (NCC533, deposit number CNCM I-1225) in treatment of a disorder selected from the group consisting of Crohn's disease, infectious diarrhea, antibiotic-associated diarrhea, gingivitis, and combinations thereof, the method comprising: rendering the L. johnsonii La1 non-replicating by a heat treatment at a temperature of 110° C. to 140° C. for 1-30 seconds; and administering the non-replicating L. johnsonii La1 to a patient having the disorder.
10. The method in accordance with claim 9 , wherein the L. johnsonii La1 (NCC533, deposit number CNCM 1-1225) are rendered non-replicating by the heat treatment for at least 10 seconds.
11. The method of claim 9 , wherein the heat treatment is at 120° C. for 15 seconds.
12. The method of claim 9 , wherein the heat treatment is performed for 10 to 20 seconds.
