The Vibrionaceae are a genetically and metabolically diverse family living in aquatic habitats with a great propensity toward developing interactions with eukaryotic microbial and multicellular hosts (as either commensals, pathogens, and mutualists). The Vibrionaceae frequently possess a life history cycle where bacteria are attached to a host in one phase and then another where they are free f...
All members of the Vibrionaceae harbour LuxO, a response regulator that integrates outputs from various signalling systems, ultimately controlling specific traits that are crucial to the distinct biology of each species. LuxO is phosphorylated in response to low cell density, activating the transcription of a family of small RNAs called Qrrs, which in turn, control the levels of a global regula...
1. The Vibrionaceae 1.1. A GENERAL DESCRIPTION Vibrio takes its name from the Latin word Vibrare, meaning 'to wave'. Otto Müller first used the word Vibrio as a descriptor in the 18 th century to describe bacteria with an elongated shape observed in culture (Rossello-Mora and Amann 2001). The family Vibrionaceae, first described by Véron (1965), resides within the g-proteobacteria, one of the f...
Vibrio fischeri belongs to the Vibrionaceae, a large family of marine gamma-proteobacteria that includes several dozen species known to engage in a diversity of beneficial or pathogenic interactions with animal tissue. Among the small number of pathogenic Vibrio species that cause human diseases are Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus, the only members of the Vibrion...
Vibrionaceae are regarded as important marine chitin degraders, and attachment to chitin regulates important biological functions; yet, the degree of chitin pathway conservation in Vibrionaceae is unknown. Here, a core chitin degradation pathway is proposed based on comparison of 19 Vibrio and Photobacterium genomes with a detailed metabolic map assembled for V. cholerae from published biochemi...
Vibrio parahaemolyticus, a species that includes strains known to be pathogenic in humans, and other Vibrionaceae are common, naturally occurring bacteria in coastal environments. Understanding the ecology and transport of these organisms within estuarine systems is fundamental to predicting outbreaks of pathogenic strains. Infaunal burrows serve as conduits for increased transport of tidal wat...
ABSTRACT Deciphering the cues that stimulate microorganisms to produce their full secondary metabolic potential promises speed up discovery of novel drugs. Ecology-relevant conditions, including carbon-source(s) and microbial interactions, are important effectors metabolite production. Vice versa metabolites mediators in although exact natural functions not always completely understood. In this...
To date 142 species have been described in the Vibrionaceae family of bacteria, classified into seven genera; Aliivibrio, Echinimonas, Enterovibrio, Grimontia, Photobacterium, Salinivibrio and Vibrio. As vibrios are widespread in marine environments and show versatile metabolisms and ecologies, these bacteria are recognized as one of the most diverse and important marine heterotrophic bacterial...
One of the major threats to seabass (Dicentrarchus labrax) aquaculture sector is development vibriosis, a disease caused mainly by bacteria from family Vibrionaceae, especially Vibrio harveyi. Given relationship between abundance in surrounding environment and prevalence fish, monitoring presence V. harveyi rearing water biofilms over time may help better understand dynamics pathogen factors th...
