Abstract:
Probes for specifically detecting and identifying H. pylori which serves as an inflammatory bacterium in digestive diseases. These probes contain a fragment formed by completely digesting a DNA carried by H. pylori with a restriction enzyme HindIII. The information of the base sequences of these probes are useful as a structural indication of primers to be used in the construction of probes specific to H. pylori by PCR or as standard sequences suitable for the comparison with genomic DNAs contained in clinical specimens.
Abstract:
Phagocytes having taken a foreign microorganism which are prepared by bringing phagocytes into contact with the microorganism and then isolating the phagocytes; a process for producing the same; and a method and a kit with the use of the same. An experimental model whereby the phagocytosis function of phagocytes can be evaluated in vitro .
Abstract:
A probe derived from phlogogenic bacteria of pneumonia, containing fragments of DNA which streptococcus pneumoniae essentially possesses, and useful for detecting and identifying causative bacteria of pneumonia is obtained by completely digesting the DNA with a restriction endonuclease Pst I, followed by cloning into a suitable vector.
Abstract:
A probe useful for rapidly detecting and identifying bacteria causative of infectious diseases is provided by completely digesting DNAs extracted from principal bacteria causative of infectious diseases with Hind III, cloning the digestion product to a suitable vector, and selecting a probe containing DNA fragments peculiar to each of the bacteria. A standard DNA sequence suitable for comparison with that of a genomic DNA contained in a clinical specimen is provided by clarifying the base sequence of the selected probe.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new probe being specifically reacted with DNAs which Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae possess, comprising a DNA contained in a genomic DNA of Escherichia coli. SOLUTION: This probe for diagnosing infections is useful for diagnosing infections with infectious disease-causing bacteria and is specifically reacted with DNAs which Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae possess. The new probe for diagnosing infections comprises at least one base sequence among base sequences of formula I, formula II, etc., contained in a genomic DNA of Escherichia coli. The probe is obtained by digesting the genomic DNA of the bacteria separated from a patient infected with the bacteria and or their combination with HindIV and selecting a fragment crossed by hybridization between a plasmid into which the fragment of the digestion is inserted and a chromosome DNA derived from the bacteria.
Abstract:
PURPOSE: To obtain a probe for diagnosing infectious diseases, containing a specific DNA fragment, specifically reacting DNA possessed by Streptococcus pneumoniae, capable of directly detecting an infectious disease cause microorganism taken in a phagocyte without multiplying the microorganism and rapidly and accurately identifying it. CONSTITUTION: This probe for diagnosing infectious diseases contains a DNA fragment obtained by treating a DNA possessed by Streptococcus pneumoniae, an infectious disease cause microorganism, with restriction enzyme PstI, is specifically reacted with the DNA possessed by Streptococcus pneumoniae and contains a base sequence of the formula.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new probe having a base sequence contained in a genomic DNA of Pseudomonas aeruginosa, comprising a DNA specifically being reacted with the DNA of the bacterium, useful for diagnosing infections with the bacterium.
