    When Listeria attacks the intestinal microbiota

    Although several Listeria strains can cause listeriosis, some are particularly virulent. This is because they secrete a toxin that damages the intestinal microbiota, preventing it from serving as a barrier and promoting infection.

    Key cellular factors for chikungunya virus replication identified

    Scientists from the Institut Pasteur, Inserm and the Max Planck Institute have used high-throughput screening to identify the cellular factors involved in the replication of chikungunya virus in human cells. These findings have revealed potential therapeutic targets that could help tackle this virus.

    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.

    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.

    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.

    How does Legionella pneumophila, the bacterium causing legionellosis, use the host cell machinery to its own advantage?

    During analysis of its genome sequence, the team from the Biology of Intracellular Bacteria Unit (Institut Pasteur/CNRS), headed by Carmen Buchrieser, identified genes coding for proteins that were predicted to be involved in the infection of human cells. These proteins resemble proteins of higher organisms (eukaryotes), including humans, and can modify the physiology of the infected host cells. They are thus potential virulence factors. In this study, published in the journal PNAS, the researchers show that one of these proteins is secreted in the human cell and helps to block the antibacterial response of the infected cells.

    Following maternal transmission, group B strep mutates to siken infants

    Group B streptococcus, a mostly benign inhabitant of healthy adults, is one of the leading causes of neonatal sepsis and meningitis. Researchers from the Institut Pasteur and Inserm have now shown that these pediatric cases might occur when the bacteria mutates within the infant following transmission from the mother.
