  "abstract": "Provided is a bacterial composition which comprises from 10 4 to 10 12 cfu/g of Pediococcus pentosaceus cells which have the ability to induce the production of interleukin-10 to reduce inflammation in the intestinal tract among other features and is useful in the amelioration of excessive crying in infants.",
  "claims": [
    "1. A method for screening and isolating novel Pediococcus pentosaceus cells, comprising the following steps: (I) assaying new Pediococcus pentosaceus cells from a pool of Pediococcus pentosaceus cells for their ability to induce the production of interleukin-10 by the following steps; (a) differentiating THP-1 monocytes into macrophages by growing the THP-1 monocyte cell line obtained from the cell collection of the Public Health England, catalogue number 88081201, in Roswell Park Memorial Institute (RPMI) 1640 medium with 10% Fetal Bovine Serum (FBS), and with phorbol 12-myristate 13-acetate (PMA) to a final concentration of 0.16 μM; (b) growing the THP-1 macrophages in RPMI 1640 medium with 10% FBS in 24-wells ELISA plates to a final concentration of 10 6 macrophages/well; (c) incubating for 2.5 hours the THP-1 macrophages with lipopolysaccharide (LPS) at a final concentration of 10 ng/ml, and washing the THP-1 macrophages with Dulbecco's Phosphate Buffered Saline medium (D-PBS); (d) getting a culture of Pediococcus pentosaceus cells ready by having grown it overnight in Man, Rogosa and Sharpe medium (MRS) at 37° C. in a 5% CO 2 atmosphere; (e) adding to each ELISA-well 500 μl of RPMI 1640 medium with 10% FBS and an appropriate amount of a dilution of Pediococcus pentosaceus cells to obtain a final ratio of 25:1, i.e. 2.5×10 7 cfu of Pediococcus pentosaceus cells: 10 6 THP-1 macrophages; (f) incubating the THP-1 macrophages with the Pediococcus pentosaceus cells for 2.5 hours at 37° C. or without the Pediococcus pentosaceus cells in the same conditions as negative control; (g) washing the THP-1 macrophages with D-PBS medium to remove the Pediococcus pentosaceus cells, subsequently adding to the THP-1 macrophages RPMI 1640 medium with 10% FBS supplemented with 50 μg/ml gentamicin, 10 μg/ml ampicillin and 12 μg/ml chloramphenicol, incubating at 37° C. at 5-7% CO 2, and taking aliquots at 5 and 24 hours; (h) centrifuging the aliquots and assaying the supernatants for interleukin-10 quantification by flow cytometry; and (i) calculating the normalized increase of interleukin-10 concentration, with the formula (IL10 24 h −IL10 5 h)/IL10 5 h; wherein IL10 5 h and IL10 24 h is the concentration of interleukin-10 in pg/ml at 5 and 24 hours, respectively; (II) selecting and isolating the new Pediococcus pentosaceus cells from the pool that induces a production of interleukin-10, expressed as normalized increase, higher than the production of interleukin-10 by the negative control, wherein said normalized increase is determined as defined in step(I).",
    "2. A method for reducing daily crying time and/or duration of crying episodes in an infant in need thereof, wherein said reduction of time and/or duration of said crying is associated with infant colic, comprising administering to said infant an amount of a bacterial composition which comprises from 10 4 to 10 12 cfu/g of Pediococcus pentosaceus viable cells, which induce the production of interleukin-10, wherein Pediococcus pentosaceus is the Pediococcus pentosaceus deposited in the Spanish Type Culture Collection under accession number CECT 8330.",
    "3. The method of claim 2, wherein said composition further comprises Bifidobacterium longum.",
    "4. The method of claim 3, wherein the Bifidobacterium longum is the Bifidobacterium longum deposited in the Spanish Type Culture Collection under the accession number CECT 7894.",
    "5. The method according to claim 2, wherein said infants have an age from three weeks to twelve months.",
    "6. The method according to claim 2, wherein said infants cry at least 60 minutes per day in three or more episodes for at least one week.",
    "7. The method according to claim 2, wherein said infants cry at least 3 hours per day for at least one week.",
    "8. The method according to claim 2, wherein said composition is administered in an amount sufficient to antagonize Gram positive and Gram negative intestinal bacteria.",
    "9. A method for reducing daily crying time and/or duration of crying episodes in an infant in need thereof, wherein said reduction of time and/or duration of said crying is associated with infant colic, comprising administering to said infant an amount of a probiotic bacterial composition which comprises from 10 4 to 10 12 cfu/g of Pediococcus pentosaceus cells which: (a) induce the production of interleukin-10; (b) antagonize Gram positive and Gram negative intestinal bacteria, wherein said Gram negative intestinal bacteria is selected from the group consisting of Escherichia coli, Enterobacter aerogenes, Klebsiella oxytoca and Bacteroides vulgatus, effective for reducing the time and/or duration of crying in said infant and wherein the Pediococcus pentosaceus cells; (c) have probiotic properties that survive the passage of the gastrointestinal tract, colonize the intestinal tract and grow in industrial medium, (d) do not produce gas and (e) have a 16S nucleic acid sequence set forth in SEQ ID NO: 1.",
    "10. The method according to claim 9, wherein said Pediococcus pentosaceus cells survive after lysozyme, hydrogen peroxide, acidic environment or bile salt treatment.",
    "11. The method according to claim 9, wherein said infants have an age from three weeks to twelve months.",
    "12. The method according to claim 9, wherein said infants cry at least 60 minutes per day in three or more episodes for at least one week.",
    "13. The method according to claim 9, wherein said infants cry at least 3 hours per day for at least one week.",
    "14. The method according to claim 13, wherein the Gram positive bacteria comprise bacteria selected from the group consisting of Clostridium difficile and Enterococcus faecalis.",
    "15. The method according to claim 9, wherein said composition further comprises Bifidobacterium longum.",
    "16. A method for reducing daily crying time and/or duration of crying episodes in an infant in need thereof, wherein said reduction of time and/or duration of said crying is associated with infant colic, comprising administering to said infant an amount of a probiotic bacterial composition which comprises (a) from 10 4 to 10 12 cfu/g of Pediococcus pentosaceus cells and (b) Bifidobacterium longum effective to induce IL-10 production and antagonize Gram positive and Gram negative intestinal bacteria, wherein said Gram negative intestinal bacteria is selected from the group consisting of Escherichia coli, Enterobacter aerogenes, Klebsiella oxytoca and Bacteroides vulgatus."
