Gallocin A, an Atypical Two-Peptide Bacteriocin with Intramolecular Disulfide Bonds Required for Activity

Streptococcus gallolyticus subsp. gallolyticus (SGG) is an opportunistic gut pathogen associated with colorectal cancer. We previously showed that colonization of the murine colon by SGG in tumoral conditions was strongly enhanced by the production of gall ...

Sulfurospirillum diekertiae sp. nov., a tetrachloroethene-respiring bacterium isolated from contaminated soil

Christof Holliger, Julien Maillard, Junxiong Wang

Two anaerobic, tetrachloroethene- (PCE-) respiring bacterial isolates, designated strain ACSDCE T and strain ACSTCE, were characterized using a polyphasic approach. Cells were Gram-stain-negative, motile, non-spore-forming and shared a vibrioid- to spirill ...

Rapid molecular evolution of Spiroplasma symbionts of Drosophila

Bruno Lemaitre, Florent François Masson

Spiroplasma is a genus of Mollicutes whose members include plant pathogens, insect pathogens and endosymbionts of animals. Spiroplasma phenotypes have been repeatedly observed to be spontaneously lost in Drosophila cultures, and several studies have docume ...

A high-content image-based drug screen of clinical compounds against cell transmission of adenovirus

Gerardo Turcatti, Fabien Kuttler

Human adenoviruses (HAdVs) are fatal to immuno-suppressed individuals, but no effective anti-HAdV therapy is available. Here, we present a novel image-based high-throughput screening (HTS) platform, which scores the full viral replication cycle from virus ...

Genomic Characterization ofMycobacterium lepraeto Explore Transmission Patterns Identifies New Subtype in Bangladesh

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Mycobacterium leprae, the causative agent of leprosy, is an unculturable bacterium with a considerably reduced genome (3.27 Mb) compared to homologues mycobacteria from the same ancestry. In 2001, the genome ofM. lepraewas first described and subsequently ...

Transformation of the Drosophila Sex-Manipulative Endosymbiont Spiroplasma poulsonii and Persisting Hurdles for Functional Genetic Studies

Bruno Lemaitre, Chloé Christiane Laurence Jollivet, Florent François Masson

Insects are frequently infected by bacterial symbionts that greatly affect their physiology and ecology. Most of these endosymbionts are, however, barely tractable outside their native host, rendering functional genetics studies difficult or impossible. Sp ...

Weevil pgrp-lb prevents endosymbiont TCT dissemination and chronic host systemic immune activation

Florent François Masson

Long-term intracellular symbiosis (or endosymbiosis) is widely distributed across invertebrates and is recognized as a major driving force in evolution. However, the maintenance of immune homeostasis in organisms chronically infected with mutualistic bacte ...

Heterogeneity in schistosomiasis transmission dynamics

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Francisco Javier Perez Saez, Marino Gatto

Simple models of disease propagation often disregard the effects of transmission heterogeneity on the ecological and epidemiological dynamics associated with host-parasite interactions. However, for some diseases like schistosomiasis, a widespread parasiti ...

The biofilm granulation mechanisms depend on the predominant bacterial populations involved

Christof Holliger, David Gregory Weissbrodt

Introduction Aerobic granular sludge used for intensified biological wastewater treatment is based on fast-settling mobile biofilms with a gel-like consistence, called “granules”, formed from activated sludge flocs (Seviour et al. 2012). Fundamental aspect ...

Spiroplasma and host immunity: activation of humoral immune responses increases endosymbiont load and susceptibility to certain Gram-negative bacterial pathogens in Drosophila melanogaster

Bruno Lemaitre, Jeremy Keith Herren

Spiroplasma poulsonii and its relatives are facultative, vertically transmitted endosymbionts harboured by several Drosophila species. Their long-term survival requires not only evasion of host immunity, but also that Spiroplasma does not have a net detrim ...
