    Discovery of the mechanism used to coordinate replication of the two Vibrio cholerae chromosomes

    Bacterial genomes generally contain a single chromosome and one or more extrachromosal elements such as plasmids. The initiation of bacterial chromosome replication must be carefully checked to ensure that chromosome duplication occurs only once per cell cycle. The bacterial pathogen responsible for cholera epidemics, Vibrio cholerae, is distinctive in that it has two chromosomes. The researchers have revealed an original, energy-saving mechanism known as the "replication checkpoint" that coordinates replication of the two chromosomes with the V. cholerae cell cycle.

    How could Zika enter Europe?

    Researchers at the Institut Pasteur have assessed the transmission potential of four populations of Aedes mosquitoes in circulation on the island of Madeira and southern France with a view to examining various possible scenarios for the introduction of Zika virus to Europe. Their work suggests that the Aedes aegypti mosquito present in Madeira is more likely to promote local transmission of Zika virus than Aedes albopictus. Consequently, it appears that the risk of a Zika epidemic in continental Europe is still low.

    Malaria: a new route of access to the heart of the parasite

    Scientists have just identified an Achilles heel in the parasite that causes malaria, by showing that its optimum development is dependent on its ability to expropriate RNA molecules in infected cells – a host-pathogen interaction that had never previously been observed.

    Airborne Bacterial Volatiles stimulate Fungal Growth

    Scientists from the team led by Jean-Paul Latgé, Director of the Aspergillus Unit at the Institut Pasteur, have discovered a new communication pathway between two pathogens that colonize the same ecological niche and are both involved in acute pulmonary pathologies, particularly in patients with cystic fibrosis (the most common genetic disease in Europe).

    Division – a key moment in establishing cell polarity

    One major line of research on the process of carcinogenesis lies in understanding the mechanisms underpinning the establishment of polarity. The Membrane Traffic and Cell Division Laboratory, directed at the Institut Pasteur by Arnaud Echard (Institut Pasteur/CNRS UMR 3691), is looking into apical-basal polarity acquisition mechanisms during cell division when organs are being formed. As part of this research, the team has recently discovered the crucial role of a GTPase-type enzyme known as Rab35.

    How Chlamydia trachomatis hijacks energy stores from its host

    A publication in eLife from researchers of the Institut Pasteur, CNRS, University of Lille and Indiana University (USA) explains the mechanisms by which the bacterium Chlamydia trachomatis hijacks nutrients of its host to its own benefit.

    Lluis Quintana-Murci appointed as Scientific Director of the Institut Pasteur

    On March 23, the Institut Pasteur announced that Lluis Quintana-Murci had been appointed as Scientific Director. This new position has been created in connection with the implementation of the general strategic plan adopted by the Institut Pasteur management. Lluis Quintana-Murci, a member of the Executive Board, will serve as the person of reference and coordinator for the Institut Pasteur's scientific teams. The aim is to facilitate the formalization and day-to-day implementation of the Institut Pasteur's scientific policies and to coordinate scientific evaluation activities and related action plans.

    A genomic study of epidemic dysentery: how Europe exported a scourge worldwide

    Scientists at the Institut Pasteur and its International Network, the Wellcome Trust Sanger Institute (Cambridge, United Kingdom) and several international institutions have just published an exceptionally wide-ranging study tracing the history of the bacillus responsible for epidemic dysentery – one of the worst scourges to afflict humans throughout the 18th and 19th centuries. This vast scientific investigation has uncovered hitherto unknown links between the various outbreaks that have occurred through history.

    Zika and microcephaly: first trimester of pregnancy most critical

    A new analysis of data from the 2013-2014 Zika epidemic in French Polynesia by scientists from the Institut Pasteur, Paris, and their French Polynesian colleagues has confirmed the incidence of grouped cases of microcephaly and quantified the risk of microcephaly associated with the virus. Using innovative mathematical modeling techniques, their research shows that the risk of microcephaly is around 1% for a fetus or newborn whose mother has been infected by the Zika virus during the first trimester of pregnancy.

    Unmasking an ancestral mechanism of integrons — key players in antibiotic resistance

    With the ultimate aim of combating antibiotic resistance acquired by bacteria during evolution, researchers from the Institut Pasteur and CNRS have managed to shed light on one of the mechanisms of DNA recombination in bacteria.
