  • Detection
  • Although work is ongoing to optimize the reaction conditions, and to determine the specificity of this method by challenging the binding of contrast agent with non-specific Ab, the present observations indicate that PAS with specific contrast enhancement is a promising method for in vivo applications, such as detection of bacterial antigens.

  • bound
  • The photoacoustic spectrum and the conventional optical absorption spectrum of the solution of C. trachomatis antigen bound to the Ab-conjugated nanorods were found to have absorption peaks at ~750nm, which is consistent with the presence of nanorod contrast agent bound on the cuvette walls.

  • carbohydrate
  • Bacterial carbohydrate structures play a central role in mediating a variety of host-pathogen interactions. (diva-portal.org)
  • Strains displaying polymeric LacNAc were generated by introducing a combination of glycosyltransferases that act on modified lipid A-cores, resulting in efficient expression of the carbohydrate epitope on bacterial cell surfaces. (diva-portal.org)
  • These bacterial strains can thus serve as tools to analyse the role of defined carbohydrate structures in different biological processes. (diva-portal.org)

  • Bacillary dysentery should not be confused with diarrhea caused by other bacterial infections. (wikipedia.org)
  • IgG4 is the least abundant IgG subclass in the serum and is often generated following repeated exposure to the same antigen or during persistent infections. (wikipedia.org)
  • occurs
  • Class-switching is mediated by the AID (activation-induced cytidine deaminase) enzyme and only occurs after the B cell binds an antigen through its B cell receptor, and is further activated through interaction with a T helper cell. (wikipedia.org)
  • complement
  • Despite the high sequence similarity (90% identical on the amino acid level), each subclass has a different half-life, a unique profile of antigen binding and distinct capacity for complement activation. (wikipedia.org)
  • Therefore
  • Therefore, it can be thought of as an antigen that is present in some members of the same species, but is not common to all members of that species. (wikipedia.org)
  • cells
  • Bacterial antigens stimulate white blood cells to release MIF into the blood stream. (wikipedia.org)
  • Odontoblasts, (the cells that form dentin) have cellular processes that extend into dentinal tubules and are the first to encounter the caries bacterial antigens. (wikipedia.org)
  • The cells are capable of sensing microbes as well as antigen capture and processing capabilities. (wikipedia.org)
  • In a person with A blood group, the plasma will contain isoantibodies against B antigens, so immediately after transfusion of blood from B group the anti-B isohemagglutinins agglutinate the foreign red blood cells. (wikipedia.org)
  • surface
  • Vi was maximally expressed inside macrophages, Vi deleted mutants stimulated macrophages during the entry into macrophages and quickly processed by macrophages, This means that S. typhi needs to mask surface antigen to enter macrophage because Vi deleted S, typhi quickly stimulated macrophages.

  • system
  • Of these, the use of genetically engineered bacterial spores has been shown to offer promise as both a mucosal as well as a heat-stable vaccine delivery system. (ei-resource.org)
  • high
  • If they demonstrate high affinity for self-antigen, one method of preventing autoimmunity is through clonal deletion. (wikipedia.org)
  • It is important to note that not all lymphocytes expressing high affinity for self-antigen undergo clonal deletion. (wikipedia.org)
  • Complete clonal deletion results in apoptosis of all B and T lymphocytes expressing high affinity for self antigen. (wikipedia.org)
