摘要:
The method for detecting and identifying a variant C. difficile strain in a sample is characterized by the following steps: (a) obtaining a sample of excreta or tissue from a human or animal patient body; (b) bringing the sample into contact with at least one antibody from each of at least three of the antibody groups group I, group II, group III, group IV, group V and group VI; (c) detecting the antibody reaction and constructing the reaction pattern; (d) comparing the reaction pattern obtained in (c) with reference patterns from known C. difficile strains and C. difficile strains the presence of which is to be tested in the investigation test; (e) assessing the agreement between the reaction pattern obtained in (c) and the reference pattern as indicative of the presence of the C. difficile strain of the reference pattern concerned in the sample.

摘要:
The present invention relates to an in vitro method that allows for delivery of exogenous antigens into the MHC class I presentation pathway of antigen-presenting cells (APCs), comprising the following steps: (a) preparation of suitable APCs; (b) determination of suitable specific method parameters for APCs, comprising (1) bringing the cells in contact with a haemolysin such as listeriolysin (LLO) and a marker substance; (2) measuring of marker substance inflow into the cells; and (3) optionally, modifying said specific parameters; and (c) delivery of exogenous antigens into the APCs, by applying the specific parameters calculated in step (b) and bringing the cells in contact with a haemolysin and the antigen of interest.
