  1. 1. The transfer of chromosomal genes through bacterial conjugation in Escherichia coli

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Arijana Katana; [2021]
    Keywords : conjugation; escherichia coli; hybrid;

    Abstract : Evolution in bacteria occurs through the combined effects of spontaneous mutations and horizontal gene transfer (HGT). Several mechanisms can lead to HGT: (i) transformation, the uptake of DNA from the environment; (ii) transduction, the transfer of DNA carried by a bacteriophage into another bacterium during infection; and (iii) conjugation, bacterial mating mediated by a conjugative plasmid like the F-factor.

  3. 2. The Importance of Bacterial Replichore Balance

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Ender Efe Cerit; [2021]
    Keywords : Salmonella; bacterial evolution; fitness cost; chromosome organization and structure; chromosomal inversion; replichore; horizontal gene transfer;

    Abstract : In most bacterial pathogens, the genome is comprised within a single circular chromosome which is typically organized by the origin-to-terminus axis that divides the chromosome into equally-sized arms of replication (replichores). This similarity in length is presumed to be required for the synchronization of the two replication forks to meet at the terminus for efficient chromosome segregation. READ MORE

  4. 3. Sepsis : Genotypic analysis of clinical Klebsiella spp. using next-generation sequencing

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Patricia Saxenborn; [2018]
    Keywords : Sepsis; Klebsiella; systems biology; next-generation sequencing; NGS;

    Abstract : Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response system and can occur when the immune system over- or under- reacts to an infection. Klebsiella spp. READ MORE

  5. 4. Generella principer för virala vektorsystem och deras tillämpning inom veterinärmedicin

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Josefin Brock von Rein; [2018]
    Keywords : viral vektor; genterapi; cancer; vaccin; veterinärmedicin;

    Abstract : Under lång tid betraktades virus enbart som ett hot mot djur och människor med stor risk att åsamka skada. Framgångar i molekylär virologi kom att bredda den uppfattningen och visa att den virala infektionsvägen var användbar för terapeutiska syften. READ MORE

  6. 5. Toxoplasma gondii : olika genotypers förekomst vid klinisk sjukdom

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Jennifer Assermark; [2014]
    Keywords : toxoplasma gondii; genotyp; virulens; klinisk toxoplasmos; människa; katt; får; viltlevande djur; genotype; virulence; clinical toxoplasmosis; human; cat; sheep; wild life;

    Abstract : Toxoplasma gondii är en intracellulär, zoonotisk parasit med förmågan att infektera i stort sett alla varmblodiga vertebrater, medan endast kattdjur kan fungera som huvudvärd. Parasiten finns spridd hos människor och djur över hela världen. Vid symptomatisk infektion med T. gondii ses en varierande klinisk bild. READ MORE
