Title: Inhibition of c. difficile infections by indigestible oligosaccharides
Inventor: GARLEB KEITH ALLEN
IPC: A61K31/7016
Filed: 1996-04-04
Abstract: The primary etiology of antibiotic-associated diarrhea (also known as pseudomembranous colitis) has been recognized as Clostridium difficile. It is believed that the indigenous microflora of a healthy individual suppresses the normally present C. difficile. However, when the indigenous microflora are disrupted (e.g., during antibiotic treatment) overgrowth of C. difficile may occur causing diarrhea and colitis. Treatment of C. difficile with antibiotics has proven effective, but many times relapse occurs; and dehydration due to diarrhea is an exacerbating problem. It has been suggested that normalization of the microflora will inhibit C. difficile relapse. Indigestible oligosaccharides have been shown to inhibit C. difficile infection. An oral rehydration solution containing such indigestible oligosaccharides also provides fluid and electrolyte replacement.

IPC: C12Q1/68
Filed: 1996-06-21
Abstract: Methods for the use of a class of dyes for improved DNA sequencing are provided. A new class of dyes, BODIPY fluorophores, has been described recently. The parent heterocyclic molecule of the BODIPY fluorophores is a dipyrrometheneboron difluoride compound which is modified to create a broad class of spectrally-discriminating fluorophores. The present invention provides methods for the use of BODIPY fluorophore-labeled DNA for dye-primer sequencing in which the BODIPYs are attached to the 5' end of sequencing primers, methods for DNA sequencing by the chain termination method of DNA sequencing and for internal labelling of polynucleotides by enzymatic incorporation of fluorescently-labeled ribonucleotides or deoxyribonucleotides, and provides oligonucleotides labelled with substituted 4,4-difluoro-4-bora-3A,4A-diaza-s-indacene (BODIPYfluorophore) compounds for perfoming the Taqman assay. BODIPY fluorophores have improved spectral characteristics compared to conventional fluorescein and rhodamine dyes. BODIPY fluorophores have narrower band width, insensitivity to solvent or pH, and improved photostability, thus, BODIPY fluorophores lead to improved DNA sequencing and/or detection in any method where electrophoresis and detection of DNA is required. Additionally, the spectral properties of the BODIPY fluorophores are sufficiently similar in wavelength and intensity to be used with conventional equipment known in the art.
