Abstract:
The invention relates to protein fragments or peptides that elicit antibodies to Gram positive bacteria which are bactericidal with complement alone without involving an opsonophagocytic mechanism, and to vaccines and conjugates comprising the same. The protein fragments or peptides comprise an immunogenic IgG binding domain, which comprises a peptide sequence of at least 8 amino acids between positions 828 and 1027 of the amino acid sequence shown in Fig. 1. The invention also relates to a polynucleotide molecule encoding the protein fragments or peptides, vectors comprising such polynucleotide molecules and host cells transformed therewith. The invention relates to a process for obtaining a substantially pure C beta protein or fragment and/or mutant thereof. The invention also relates to a method of inducing an immune response in an animal, comprising administering the vaccine of the invention to an animal in a therapeutically effective amount in a pharmaceutically acceptable carrier.
Abstract:
The use of protein H, and fragments or derivatives thereof, as cytostatic agents, especially in the treatment of diseases involving undesired cell proliferation.
Abstract:
The present invention relates generally to molecular compounds which encode the protective M-like protein of Streptococcus equi (SeM), the amino acid compound which is thereby encoded, and compositions of matter which incorporate either the encoding compounds or the cellular components for which they encode. For instance, vaccines which utilize the amino acid compounds or vectors and cell lines useful to make the amino acid compounds described herein are subjects of the present invention. The present invention provides methods to stimulate S. equi-specific immune response in horses. It also provides diagnostic assays for Streptococcus equi.
Abstract:
The present invention relates to the identification and use of a family of human complement C3-degrading proteinases expressed by S. pneumoniae. The proteinase has a molecular weight of about 24 kD to about 34 kD as determined on a 10 % SDS polyacrylamide gel. A preferred proteinase of this invention includes the amino acid sequence of SEQ ID NO:2.

Abstract:
The present invention provides a purified bacterial protein expressed during infection due to streptococci or enterococci and isolated from human sera, together with immunogenic fragments, analogs, inhibitors, antibodies and antigenic fragments specific thereto. Also provided is a DNA sequence coding for a bacterial protein or an immunogenic fragment or an analogue thereof expressed during infection due to Streptococci or Enterococci, together with homologues thereof, together with vectors, probes and inhibitors therefor. Also provided is fibronectin or an immunogenic fragment thereof or an analogue thereof or an antibody thereto or an antigen binding fragment thereof when used in a method of treatment or diagnosis of the human or animal body for infection due to Streptococci or Enterococci. Also provided are antibodies specific to HSP 90 or immunogenic fragments or analogues thereof for use in a method of diagnosis or treatment of the human or animal body of infection due to streptococci or enterococci due to any one of the group of S.oralis, S.gordonii, S.sanguis.
Abstract:
The present invention relates to bacterial strains of Lactococcus lactis or Lactococcus cremoris, usable as starter cultures, able to provide both satisfactory rheological and organoleptic proper-ties, and satisfactory shelf life to a plant-based media into which they are incorporated. The in-vention also provides a composition comprising one of these strains of Lactococcus lactis or Lactococcus cremoris, and feed or food products, in particular a plant-based feed or food product obtained with these strains.
Abstract:
The present invention uses microfluidics droplets for studying the growth dynamics of communities of bacteria in the presence of various perturbations such as various chemicals or other microorganisms and to establish microbial assemblies model which is representative of a microbiota of interest and to examine their growth dynamics after perturbations such as with an array of chemicals or other microorganisms. In particular, the present invention refers to a method and apparatus for assessing the effect of a chemical or biological substance on the growth of microorganisms.
