  • Human Anelloviruses: diverse, omnipresent and commensal members of the virome
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2020-03-19
    Kaczorowska J, van der Hoek L.

    Anelloviruses are small, single stranded circular DNA viruses. They are extremely diverse and have not been associated with any disease so far. Strikingly, these small entities infect most probably the complete human population, and there are no convincing examples demonstrating viral clearance from infected individuals. The main transmission could be via fecal-oral or airway route, as infections occur

    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-07-12
    Yu Fu,Landon Pastushok,Wei Xiao

    After exposure to DNA-damaging agents, both prokaryotic and eukaryotic cells activate stress responses that result in specific alterations in patterns of gene expression. Bacteria such as Escherichia coli possess both lesion-specific responses as well as an SOS response to general DNA damage, and the molecular mechanisms of these responses are well studied. Mechanisms of DNA damage response in lower

  • Influence of BCG vaccine strain on the immune response and protection against tuberculosis.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-07-12
    Nicole Ritz,Willem A Hanekom,Roy Robins-Browne,Warwick J Britton,Nigel Curtis

    The Bacille Calmette-Guérin (BCG) vaccine has been used for more than 80 years to protect against tuberculosis. Worldwide, over 90% of children are immunized with BCG, making it the most commonly administered vaccine, with more than 120 million doses used each year. Although new tuberculosis vaccines are under investigation, BCG will remain the cornerstone of the strategy to fight the worsening tuberculosis

  • The diversity of small eukaryotic phytoplankton (< or =3 microm) in marine ecosystems.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-20
    Daniel Vaulot,Wenche Eikrem,Manon Viprey,Hervé Moreau

    Small cells dominate photosynthetic biomass and primary production in many marine ecosystems. Traditionally, picoplankton refers to cells < or =2 microm. Here we extend the size range of the organisms considered to 3 microm, a threshold often used operationally in field studies. While the prokaryotic component of picophytoplankton is dominated by two genera, Prochlorococcus and Synechococcus, the eukaryotic

  • The early steps of glucose signalling in yeast.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-19
    Juana M Gancedo

    In the presence of glucose, yeast undergoes an important remodelling of its metabolism. There are changes in the concentration of intracellular metabolites and in the stability of proteins and mRNAs; modifications occur in the activity of enzymes as well as in the rate of transcription of a large number of genes, some of the genes being induced while others are repressed. Diverse combinations of input

  • Quorum sensing and virulence regulation in Xanthomonas campestris.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-19
    Ya-Wen He,Lian-Hui Zhang

    It is now clear that cell-cell communication, often referred to as quorum sensing (QS), is the norm in the prokaryotic kingdom and this community-wide genetic regulatory mechanism has been adopted for regulation of many important biological functions. Since the 1980s, several types of QS signals have been identified, which are associated commonly with different types of QS mechanisms. Among them, the

  • Role of microorganisms in the evolution of animals and plants: the hologenome theory of evolution.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-14
    Ilana Zilber-Rosenberg,Eugene Rosenberg

    We present here the hologenome theory of evolution, which considers the holobiont (the animal or plant with all of its associated microorganisms) as a unit of selection in evolution. The hologenome is defined as the sum of the genetic information of the host and its microbiota. The theory is based on four generalizations: (1) All animals and plants establish symbiotic relationships with microorganisms

  • Genetics and cell biology of magnetosome formation in magnetotactic bacteria.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-10
    Dirk Schüler

    The ability of magnetotactic bacteria (MTB) to orient in magnetic fields is based on the synthesis of magnetosomes, which are unique prokaryotic organelles comprising membrane-enveloped, nano-sized crystals of a magnetic iron mineral that are aligned in well-ordered intracellular chains. Magnetosome crystals have species-specific morphologies, sizes, and arrangements. The magnetosome membrane, which

  • Aminoacyl-tRNA synthetase complexes: molecular multitasking revealed.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-06-05
    Corinne D Hausmann,Michael Ibba

    The accurate synthesis of proteins, dictated by the corresponding nucleotide sequence encoded in mRNA, is essential for cell growth and survival. Central to this process are the aminoacyl-tRNA synthetases (aaRSs), which provide amino acid substrates for the growing polypeptide chain in the form of aminoacyl-tRNAs. The aaRSs are essential for coupling the correct amino acid and tRNA molecules, but are

  • Species divergence and the measurement of microbial diversity.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-04-26
    Catherine A Lozupone,Rob Knight

    Diversity measurement is important for understanding community structure and dynamics, but has been particularly challenging for microorganisms. Microbial community characterization using small subunit rRNA (SSU rRNA) gene sequences has revealed an extensive, previously unsuspected diversity that we are only now beginning to understand, especially now that advanced sequencing technologies are producing

  • From soil to gut: Bacillus cereus and its food poisoning toxins.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-04-22
    Lotte P Stenfors Arnesen,Annette Fagerlund,Per Einar Granum

    Bacillus cereus is widespread in nature and frequently isolated from soil and growing plants, but it is also well adapted for growth in the intestinal tract of insects and mammals. From these habitats it is easily spread to foods, where it may cause an emetic or a diarrhoeal type of food-associated illness that is becoming increasingly important in the industrialized world. The emetic disease is a

  • Diversity and occurrence of Burkholderia spp. in the natural environment.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-04-22
    Stéphane Compant,Jerzy Nowak,Tom Coenye,Christophe Clément,Essaïd Ait Barka

    Both in natural and in managed ecosystems, bacteria are common inhabitants of the phytosphere and the internal tissues of plants. Probably the most diverse and environmentally adaptable plant-associated bacteria belong to the genus Burkholderia. This genus is well-known for its human, animal and plant pathogenic members, including the Burkholderia cepacia complex. However, it also contains species

  • Heterogeneity of large clostridial toxins: importance of Clostridium difficile toxinotypes.
    FEMS Microbiol. Rev. (IF 11.524) Pub Date : 2008-04-10
    Maja Rupnik

    Clostridium difficile toxinotypes are groups of strains defined by changes in the PaLoc region encoding two main virulence factors: toxins TcdA and TcdB. Currently, 24 variant toxinotypes (I-XXIV) are known, in addition to toxinotype 0 strains, which contain a PaLoc identical to the reference strain VPI 10463. Variant toxinotypes can also differ from toxinotype 0 strains in their toxin production pattern
