  2. 1. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

    Author : Crister Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

    Abstract : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. READ MORE

  4. 2. Lactobacillus in semi-hard cheese and their use as adjunct cultures

    Author : Martin Antonsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Adjunct culture; NSLAB; Non-starter Lactic acid bacteria; Cheese ripening; Model cheese; Lactobacillus paracasei; Cheese; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The microflora of Herrgård cheese produced at three dairies was compared after three and six months maturation. The microflora of cheeses from two of the dairies was dominated by a spontaneous microflora of Lactobacillus after three months of ripening, while starter bacteria still dominated in cheese from the third dairy after six months.

  5. 3. Identification and characterisation of bacteria based on 16S rDNA techniques with special reference to Helicobacter pylori in the gastro-intestinal tract

    Author : Annika Tiveljung; Anders Sjöstedt; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The overall aim of this study was to establish molecular techniques for the detection and identification of "difficult to grow" - bacteria in mixed bacterial populations in clinical samples without the need for culturing procedures.Material and Methods: Thirty-nine strains of Mobiluncus were used as a model system for phylogenetic classification of fastidious bacteria based on 16S ribosomal DNA (rDNA) sequences.

  6. 4. Systematics of Lactobacillus spp. of probiotic potential

    Author : Alejandra Vasquez; Avdelningen för medicinsk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mikrobiologi; bakteriologi; virologi; mykologi; Food and drink technology; Livsmedelsteknik; mycology; virology; bacteriology; Microbiology; bacteria; molecular-based identification; probiotics; systematics;

    Abstract : Lactobacillus is a heterogeneous bacterial genus comprising at present 91 species. The high species number often makes classification and identification difficult, especially as the taxonomy to a high degree has been based on phenotypical traits. READ MORE

  7. 5. Experimental Helicobacter pylori infection in an animal model

    Author : Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. READ MORE
