2009-05-01ZeitschriftenartikelbdhA-patD operon as a virulence determinant, revealed by a novel large-scale approach for identification of Legionella pneumophila mutants defective for amoeba infection. Legionella pneumophila, the causative agent of Legionnaires' disease, is an intracellular parasite of eukaryotic cells. In the environment, it colonizes amoebae. After being inhaled into the human lung, the bacteria infect ...

2011-07-27ZeitschriftenartikelConstruction of a lytically replicating Kaposi's sarcoma-associated herpesvirus (KSHV) Karposi's sarcoma-associated herpesvirus (KSHV) is found predominantly in a latent state in most cell types, impeding investigations of the lytic replication cycle. Here, we engineered the cloned KSHV genome, bacterial ...

2005-11-08ZeitschriftenartikelDas langsame Wachstum von Mykobakterien - Mögliche Ursachen und Bedeutung für die Pathogenität Die Gattung Mycobacterium weist als charakteristische Eigenschaft lange sowie bei verschiedenen Spezies der Gattung stark voneinander abweichende Generationszeiten auf. Alle hochpathogenen Spezies wie der Tuberkuloseerreger ...

2009-11-18ZeitschriftenartikelDeletion of the rat cytomegalovirus immediate-early 1 gene results in a virus capable of establishing latency, but with lower levels of acute virus replication and latency that compromise reactivation efficiency The immediate-early 1 (IE1) and IE2 proteins encoded by the major immediate-early (MIE) transcription unit of cytomegaloviruses are thought to play key roles in the switch between latent- and lytic-cycle infection. Whilst ...

The IE1 and IE2 proteins encoded by the major immediate-early (MIE) transcription unit of cytomegaloviruses are thought to play key roles in the switch between latent and lytic cycle infection. Whilst IE2 is essential for ...

2012-09-11ZeitschriftenartikelIllegitimate recombination: An efficient method for random mutagenesis in Mycobacterium avium subsp. hominissuis Background: The genus Mycobacterium (M.) comprises highly pathogenic bacteria such as M. tuberculosis as well as environmental opportunistic bacteria called non-tuberculous mycobacteria (NTM). While the incidence of ...

2013-07-18ZeitschriftenartikelLegionella oakridgensis ATCC 33761 genome sequence and phenotypic characterization reveals its replication capacity in amoebae Legionella oakridgensis is able to cause Legionnaires’ disease, but is less virulent compared to L. pneumophila strains and very rarely associated with human disease. L. oakridgensis is the only species of the family ...
