    Notes: Abstract: A prototype ‘advisor’ system intended to answer typical questions from a user of a commercial fourth generation report writer has been developed. This paper describes a major subcomponent, which uses expert system techniques to answer ‘why’ or ‘causal’ questions. The approach uses several types of rules, used both forward and backward, to define causal relations between the user's actual code and English-like descriptions of the intended or actual results. The Prolog-based rule interpreter, which can deal with negative and inconsistent questions, is outlined. The design is based on a large corpus of actual user questions.

    Development of mycobacterial species-specific DNA probes by subtraction hybridization (1997)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 156 (1997), S. 0

    Notes: Subtraction hybridization was used to identify sequences of Mycobacterium bovis DNA which might be of diagnostic value. Genomic DNA from Mycobacterium avium, isolated commonly from cattle and whose tuberculin is used in the comparative intradermal tuberculin test, was subtracted from M. bovis genomic DNA. A novel sequence, of 131 bp, which appears to be Mycobacterium tuberculosis complex-specific was identified. The specificity of this sequence was stringently tested by a probe and polymerase chain reaction (PCR) assay. Nucleotide identity determination and sequence comparisons revealed that the 131-bp sequence is located directly upstream of a potential isocitrate dehydrogenase (IDH) coding gene and may be of diagnostic value, enabling differentiation of M. tuberculosis complex mycobacteria from other mycobacterial species.
