    Abstract : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. READ MORE

  4. 2. Growth in Aging Colonies : The Importance of Being Different

    Author : Marie Wrande; Diarmaid Hughes; Måns Ehrenberg; Mikael Rhen; Uppsala universitet; []
    Keywords : ;

    Abstract : The accumulation of rifampicin resistant (RifR) mutants in aging bacterial colonies has previously been attributed to stress-induced mutagenesis. Mutations giving rise to RifR are located in the rpoB gene, coding for the β subunit of RNA polymerase, RpoB. READ MORE

    Abstract : Neisseria meningitidis, also known as the meningococcus, is a globally spread obligate human bacterium causing meningitis and/or septicaemia. It is responsible for epidemics in both developed and developing countries. READ MORE

  6. 4. Molecular characterisation of antibiotic resistance in Mycobacterium tuberculosis

    Author : Pontus Juréen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : To counteract the emergence of multi-drug resistant tuberculosis (MDR-TB) a number of approaches have been proposed, amongst which are the sound usage of the present anti-TB drugs and the development of prompt and specific tools for the diagnosis of resistance. To examine the role of drugs in the treatment of resistant TB, we investigated the general crossresistance between kanamycin and amikacin, which has been reported in numerous studies. READ MORE

  7. 5. Molecular detection and characterization of drug-resistant Mycobacterium tuberculosis

    Author : Anna Engström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Tuberculosis (TB) is an ancient disease, but not a disease of the past. Despite the declaration of TB as a global emergency by the World Health Organization in 1993 the worldwide problem of TB has worsened. READ MORE
