  1. 1. Quorum sensing och quorum quenching : bakteriers förmåga att kommunicera med varandra, och vägar att störa denna mekanism för att hämma infektion

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

    Author : Moa Therése Viklund; [2019]
    Keywords : Quorum sensing; QS; quorum quenching; QQ; QSI; bakteriekommunikation; interspecies kommunikation; AI1; AI2; autoinducerare; homoserin lakton; AHL; AIP; antimikrobiell aktivitet; resistensutveckling;

    Abstract : Den här litteraturstudien syftar till att översiktligt förklara hur bakterier kommunicerar med varandra och att sammanfatta hur mekanismen kan hämmas, med syfte att minska bakteriers virulens och förmåga att manifestera infektion. Quorum sensing är bakteriers förmåga att kommunicera med varandra och ger dem möjligheten att uppvisa en form av multicellularitet. READ MORE

  2. 2. Analysis and Implementation of an Age Structured Model of the Cell Cycle

    University essay from Lunds universitet/Matematik LTH

    Author : Anna Broms; [2017]
    Keywords : age structured model; cell cycle; cell population dynamics; nonlinear integral equations; Romberg s method; Mathematics and Statistics;

    Abstract : In an age-structured model originating from cancer research, the cell cycle is divided into two phases: Phase 1 of variable length, consisting of the biologically so called G1 phase, and Phase 2 of fixed length, consisting of the so called S, G2 and M phases. A system of nonlinear PDEs along with initial and boundary data describes the number densities of cells in the two phases, depending on time and age (where age is the time spent in a phase).

  3. 3. The regulatory effect of CsrA on cstA, glgCAP and flhDC in an RNase P ts mutant Escherichia coli

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Zeinalabedin Hilow; [2017]
    Keywords : CsrA; CsrB; CsrC; CsrD; GlgCAP; FlhDC; CstA; E. Coli; Glolbal regulator; RNase P; C5; ts; wt;

    Abstract : CsrA is a global post-transcriptional regulatory protein that has a great impact on many physiological pathways in a cell. It regulates central carbon metabolism, motility and biofilm formation as well as virulence, pathogenesis, quorum sensing and the oxidative stress response. READ MORE

  4. 4. Isolation of luminescent bacteria from Bay of Bengal and their molecular characterization

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Alex Ranjith Kumar; [2010]
    Keywords : sea water; luminescent bacteria; bay of bengal;

    Abstract : Luminescence is the emission of light by an object. Living organisms including certain bacteria are capable of luminescence. Bacteria are the most abundant luminescent organisms in nature. Bacterial luminescence has been studied most extensively in several marine bacteria. READ MORE
