  • Patent number: 11253172
    Abstract: A device for analyzing the regularity and symmetry of a sequence of N gait or running cycles of a person, comprising sensors for measuring raw time signals of a physical movement variable of a body segment, a processing unit connected to the sensors for measuring and configured to separate the raw time signals into distinct time signals Ci, the Ci series being associated with a given gait or running cycle i of the person, to calculate at least one similarity coefficient between the signal Ci associated with gait or running cycle i and another signal Cj associated with a gait or running cycle j of the person. A display is configured to display the matrix M(i,j) with each value of the similarity coefficient shown in the matrix M(i,j) in color to form a graduated color scale indicating the similarity between the gait or running cycles i and j.

  • Patent number: 11041147
    Abstract: The present invention relates to a bacteriophage strain capable of producing a lytic infection in the Escherichia coli ST131-025b:H4 clone. The burden of ST131-025b:H4 Escherichia coli clonal complex in human community and hospital-acquired infections is increasing worldwide, going along with a worrying and growing resistance to betalactams and fluoroquinolones. Bacteriophage LM33_P1 infects exclusively (100% specificity) 025b E. coli strains with 70% coverage on the two major antibiotic resistant pandemic clonal complexes ST131-025b:H4 and ST69-025b. The inventors evaluated the in vivo activity of bacteriophage LM33_P1 using three different extraintestinal virulence murine models and showed that it infects bacteria in several organs.

  • Publication number: 20190120838
    Abstract: The present invention relates to methods and kits for the rapid detection of the Escherichia coli O25b-ST131 clone. The inventors have isolated a podoviridae bacteriophage (LM33_P1) infecting the E. coli strain LM33 isolated from ventilator associated pneumonia and which belongs to clone STI3I-025b. By testing different strains of E coli belonging to 129 others various distinct serotypes (including twelve O25a) the inventors found that bacteriophage LM33_P1 is able to infect exclusively O25b strains (none of non-O25b strains could be infected by LM33_P1). The inventors have determined that the specificity displayed by bacteriophage LM33_P1 to infect only 025b serotype strains is based on a very specific polypeptide (Gp17) used by LM33_P1 to attach the bacterial cell via LPS molecule. In particular, the present invention relates to a polypeptide comprising an amino acid sequence having at least 80% of identity with the amino acid sequence set forth in SEQ ID NO:1.
