  • Method for calibrating antibiotic disk diffusion testing of microorganisms
    Patent number: 7465559
    Abstract: A method for calibrating antimicrobic susceptibility testings of microorganisms comprises the steps of creating a histogram with a high response side and a low response side of isolates from a microbial species, which may contain resistant strains against an antimicrobial agent, calculating from the high response side of the histogram at least one statistical parameter, and defining a limit for susceptibility interpretation and comparative analysis of antimicrobic resistance, which is based on the statistical parameter. This limit separates susceptible strains from resistant strains against an antimicrobial agent.

  • Protein G and/or fragments thereof
    Patent number: 5108894
    Abstract: A hybrid DNA molecule is disclosed by this invention capable of cellular expression comprising the DNA sequence for protein G. Said DNA sequence has substantially the same IgC binding properties as naturally occurring protein G. The molecule may be comprised of DNA sequences coding for fragments of protein G. Moreover, said DNA sequence may code for both fragments of protein G and protein G. The DNA sequence can be isolated from streptococcal DNA.

  • Purified protein G from streptococcal bacteria
    Patent number: 4948874
    Abstract: A process is disclosed for recovering a cell wall protein, particularly a Fc-receptor, from streptococcal bacteria. In the process, streptococcal bacteria are treated with at least one proteolytic enzyme to solubilize the cell wall protein. A process is also disclosed for recovering Fc-receptor type III (protein G) having selective IgG-binding capability (i.e., no albumin-binding capability) from streptococcal bacteria by pretreating these bacteria with enzymes prior to said enzymatic solubilization.
