    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DNA polymerase; sample treatment; pre-PCR processing; real-time PCR; Food-borne pathogens;

    Sammanfattning : Since the development of real-time PCR, the technology has been widely applied in the field of diagnostics. In comparison with conventional PCR it has opened up the possibility of accurate quantification of microorganisms in clinical, environmental and food samples. LÄS MER

  3. 2. Microbiological hygiene and biological control of leafy green vegetables

    Författare :Elisabeth Uhlig; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Food hygiene; Biological control; Native microbiota; Escherichia coli; Leafy green vegetables;

    Sammanfattning : Fruit and vegetables are vital components of a healthy diet, and international strategies to encourage their consumption are in place (FAO/WHO, 2005). Ready-to-eat (RTE) leafy green vegetable products have exploded in popularity, and are a convenient and attractive way to add greens to the plate. LÄS MER

  4. 3. Identification of novel antibiotic resistance genes through the exploration of mobile genetic elements

    Författare :Mohammad Razavi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Environment; Metagenomics; Antibiotic resistance; Mobile genetic elements; Insertion sequences; Integron; Resistome; Next-generation sequencing;

    Sammanfattning : Backgrounds and aims: The evolution of multi-resistant pathogens is seriously threatening our ability to provide modern healthcare. Many of the mobile resistance factors in clinics appear to originate from environmental bacteria. LÄS MER

  5. 4. A Molecular Approach for Investigation of the Prevalence and Neurotoxin Formation of Clostridium botulinum in Food Safety Assessment

    Författare :Maria Lövenklev; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neurotoxin gene expression; neurotoxin; food safety assessment; food preservation; Clostridium botulinum; enrichment PCR; Food and drink technology; qRT-PCR; Livsmedelsteknik; prevalence;

    Sammanfattning : In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategies for food preservation and risk assessment.

  7. 5. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Sammanfattning : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. LÄS MER
