  1. 21. Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics

    University essay from SLU/Dept. of Microbiology

    Author : Tua Lilja; [2013]
    Keywords : antibiotics; natural products; marine microorganisms; isolation methods; actinomycetes; rare actinomycetes; whole-cell screening; antimicrobials; antibiotic resistance;

    Abstract : The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens.

  3. 22. Evaluation of flow cytometry as replacement for plating in in vitro measurements of competitive growth under antibiotic stress

    University essay from Infektionssjukdomar

    Author : Christer Malmberg; [2013]
    Keywords : Flow cytometry; competetive growth; antibiotics;

    Abstract : A method for measuring cell concentration and identity based on flow cytometry (FCM) and fluorescent marking is developed and subsequently compared with traditional plating based methods, with regards to performance, economy and ergonomy. The emphasis is on competitive growth of bacteria under antibiotic stress, but the technique could be used in any situation requiring fast, high throughput counting and identification of cellular populations.

  4. 23. Frekventa mjölkningar av kor i samband med celltalsförhöjningar i mjölken

    University essay from SLU/Dept. of Clinical Sciences

    Author : Liza Engqvist; [2013]
    Keywords : Frekventa mjölkningar; Förhöjda celltal; SCC; Mastit; AMS;

    Abstract : Mastit (juverinflammation) är en mycket vanlig sjukdom hos mjölkkor som orsakar mjölkproducenterna stora ekonomiska förluster genom nedsatt produktion och mjölkkvalitet och representerar en avsevärd antibiotikaanvändning. Klinisk mastit (KM) ger synliga symtom som t.ex. juversvullnad. READ MORE

  5. 24. Counting Sertoli Cells in Thin Testicular Tissue

    University essay from Institutionen för informationsteknologi

    Author : Abdolrahim Kadkhodamohammadi; [2012]
    Keywords : ;

    Abstract : This master thesis develops a novel system to model the tubular structure in thin sections of testicular tissue and count the Sertoli cells. A three-phase method is proposed to model the tubular structure in microscopic images of the tissue, the model is deployed to detect the cells. READ MORE

  6. 25. Fluorescence Lifetime Measurement using Time Correlated Single Photon Counting

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Kemisk fysik

    Author : Mohammad Bilal Akhtar; [2010]
    Keywords : Chemistry;

    Abstract : A time correlated single photon counting (TCSPC) setup is built to measure the fluorescence decay of samples, such as solar cell materials. TCSPC is a sensitive technique for measuring fluorescence decays on nanosecond time scale and longer. READ MORE
