  1. 1. Host epithelium integrity in the female reproductive tract during Neisseria gonorrhoeae infection

    Författare :Linda Weyler; Helena Aro; Lene Rasmussen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Female reproductive tract; Neisseria gonorrhoeae; VK2 E6E7 cells; DNA damage; cell cycle; mitosis; restriction endonucleases; infection models; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Neisseria gonorrhoeae infections are asymptomatic in approximately fifty percent of the affected women. Left untreated, this can develop into a long-term inflammatory state with detrimental secondary complications such as ectopic pregnancy and sterility. Furthermore, studies have shown that N. LÄS MER

  3. 2. Endonuclease II - a GIY-YIG enzyme of bacteriophage T4

    Författare :Pernilla Lagerbäck; Karin Carlson; Elisabeth Raleigh; Uppsala universitet; []

    Sammanfattning : Endonuclease II (EndoII) of bacteriophage T4 is a GIY-YIG enzyme involved in host DNA breakdown during phage infection of E. coli. EndoII combines features of restriction endonucleases with those of homing endonucleases in that it breaks down DNA foreign to itself but recognizes a 16 bp long asymmetric and ambiguous sequence.

  4. 3. Diversity of thermostable DNA enzymes from Icelandic hot springs

    Författare :Sigridur Hjorleifsdottir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermophiles; microbial diversity; SSU rRNA; Thermus; hot springs; Biotechnology; Bioteknik; Biochemistry; enzymologi; Proteiner; enzymology; metabolism; Proteins; DNA enzymes; Biokemi;

    Sammanfattning : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. LÄS MER

  5. 4. Genotypic and phenotypic characterisation of Neisseria gonorrhoeae

    Författare :Magnus Unemo; Bengt Wretlind; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The bacterium Neisseria gonorrhoeae (the gonococcus) is the aetiological agent of gonorrhoea, which remains a major sexually transmitted infection/disease (STI/STD) worldwide. The incidence of gonorrhoea was previously high in many countries, Sweden included. The incidence in Sweden culminated in 1970 with 487 cases per 100,000 inhabitants. LÄS MER
