Correction to: “In Silico Detection of Virulence Gene Homologues in the Human Pathogen Sphingomonas Spp.”
There is an ongoing debate about the clinical significance of Sphingomonas paucimobilis as a virulent bacterial pathogen. In the present study, we investigated the presence of different virulence factors and genes in Sphingomonas bacteria. We utilized phylogenetic, comparative genomics and bioinformatics analysis to investigate the potentiality of Sphingomonas bacteria as virulent pathogenic ba...
متن کاملBacterial outer membrane vesicles and the host-pathogen interaction.
Extracellular secretion of products is the major mechanism by which Gram-negative pathogens communicate with and intoxicate host cells. Vesicles released from the envelope of growing bacteria serve as secretory vehicles for proteins and lipids of Gram-negative bacteria. Vesicle production occurs in infected tissues and is influenced by environmental factors. Vesicles play roles in establishing ...
متن کاملElicitation and suppression of microbe-associated molecular pattern-triggered immunity in plant-microbe interactions.
Recent studies have uncovered fascinating molecular mechanisms underlying plant-microbe interactions that coevolved dynamically. As in animals, the primary plant innate immunity is immediately triggered by the detection of common pathogen- or microbe-associated molecular patterns (PAMPs/MAMPs). Different MAMPs are often perceived by distinct cell-surface pattern-recognition receptors (PRRs) and...
متن کاملMetabolism of the vacuolar pathogen Legionella and implications for virulence
Legionella pneumophila is a ubiquitous environmental bacterium that thrives in fresh water habitats, either as planktonic form or as part of biofilms. The bacteria also grow intracellularly in free-living protozoa as well as in mammalian alveolar macrophages, thus triggering a potentially fatal pneumonia called "Legionnaires' disease." To establish its intracellular niche termed the "Legionella...
متن کاملVirulence and Pathogen Multiplication: A Serial Passage Experiment in the Hypervirulent Bacterial Insect-Pathogen Xenorhabdus nematophila
The trade-off hypothesis proposes that the evolution of pathogens' virulence is shaped by a link between virulence and contagiousness. This link is often assumed to come from the fact that pathogens are contagious only if they can reach high parasitic load in the infected host. In this paper we present an experimental test of the hypothesis that selection on fast replication can affect virulenc...
