摘要:
Clostridium difficile is one of the most common causes of health-care acquired diarrhoea, resulting in a spectrum of disease from mild diarrhoea to life-threatening illness. Particular human Lactobacillus strains, including Lactobacillus gasseri APC678, are described as useful therapeutic agents to target C. difficile colonisation or infection.
摘要:
An antimicrobial which is effective against a range of Gram positive organisms is described. The antimicrobial is the bacteriocin lacticin 3147, which is shown to be effective both in vivo and in vitro against a range of Gram positive organisms.
摘要:
A non-therapeutic method of reducing weight gain, serum cholesterol levels, or liver triglyceride levels, in a non-obese mammal, comprises the step of administering to the gut of a mammal an effective amount of a bacteria expressing a BSH1 enzyme of SEQUENCE ID NO: 1, or a functional variant thereof; a BSH1 enzyme of SEQUENCE ID NO: 1, or a functional variant thereof for use as a medicament; isolated bacterial strains expressing functional variants of BSH1.

摘要:
The present invention relates to a nisin derivative comprising amino acid substitutions in the peptide sequence encoding the hinge region of the protein, wherein the derivative exhibits an increased anti-microbial activity.
摘要:
The invention relates to a variant nisin peptide, wherein the variant nisin peptide is a modified variant of wild-type nisin, wherein the modification comprises or consists of an amino acid residue modification selected from: i) M17Q or M17A; ii) T2L; and iii) one set of modified hinge residues selected from a) N20H and M21T, b) N20V, M21G, and K22A, c) N20V, M21G, and K22V or d) N20V, M21G, and K22T; or v) combinations of modifications i), ii), and iii), and related medical uses and products comprising such nisin peptides.
摘要:
An isolated lantibiotic is provided comprising amino acid sequence SEQ. ID No. 2 and at least one of amino acid sequences SEQ. ID No. 4 and SEQ. ID. No 6. Also provided is use of the lantibiotic in the treatment or prevention of infection by Group B Streptococcus or Corynebacterium xerosis. The invention further relates to isolated S. hominis strains and use of same in producing the lantibiotic. A vector is provided comprising nucleotides sequences for producing the lantibiotic.
