  • Publication number: 20230405062
    Abstract: The invention herein relates generally to enhancing the survival and activity of probiotic Lactobacillus reuteri strains in mammals by pre-conditioning L. reuteri with GOS during cultivation and to a surprisingly high symbiotic effect of such a pre-conditioned probiotic L. reuteri strain when administered together with GOS further added in the composition. The invention therefore comprises methods for cultivating and manufacturing probiotic L. reuteri strains, and preparing products containing such pre-conditioned strains in combination with additional amounts of GOS. In more detail the present invention relates to a probiotic composition comprising a probiotic L. reuteri strain, obtained by a step of growing the bacteria in a medium comprising GOS, and administering the pre-conditioned bacteria together with further GOS in the final product. The inventors have found that such method induces surprisingly high and unexpected symbiotic beneficial effects of the probiotic bacteria in the gastrointestinal tract.

  • Publication number: 20230362468
    Abstract: An optical sensor system (1) has plural optical lens systems (2a-2n), a single imaging optical sensor (3) and plural light guides (4a-4n) corresponding to the number of optical lens systems (2a-2n). The light guides (4a-4n) extend respectively between the lens systems (2a-2n) and the optical sensor (3). Each of the lens systems (2a-2n) is associated respectively with one of the light guides (4a-4n). A switching apparatus (5) selectively switches between the light guide means (4a-4n).

  • Publication number: 20230338441
    Abstract: The present invention relates to novel strains of lactic acid bacteria, more specifically, novel strains of Lactobacillus reuteri, capable of utilizing ethanolamine. This characteristic makes it possible for the bacteria to compete for the same substrate as pathogenic ethanolamine-utilizing pathogens, thereby presenting an effective means to combat infections resulting from such pathogenic bacteria. There is also provided a method of selecting further ethanolamine-utilizing lactic acid bacteria, as well as other methods and uses involving said novel strains and other ethanolamine-utilizing lactic acid bacteria.

  • Patent number: 11602551
    Abstract: The present invention provides the use of inosine in the treatment of a disease associated with Treg deficiency or Treg dysfunction, in particular immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX). In one embodiment of the invention, the inosine can be provided in the form of a bacterial strain that is capable of stimulating the production of inosine. Methods for stimulating the production of inosine in a subject using said strains are also provided, as are methods for the selection of a bacterial strain capable of stimulating inosine production in a subject.

  • Publication number: 20220354909
    Abstract: The invention relates to selection of bacterial strain for use in treating serotonin deficiency and/or a disease related to serotonin deficiency by culturing bacteria of a lactic acid producing bacterial strain, under aerobic conditions, in a culture medium comprising tryptophan. Any serotonin produced by the bacteria of the lactic acid producing bacterial strain in the culture medium is detected and the lactic acid producing bacterial strain is selected as effective in treating serotonin deficiency and/or a disease related to serotonin deficiency in a subject if serotonin is detected in the culture medium.
