Host control of the microbiome: Mechanisms, evolution, and disease

Science, Journal Year: 2024, Volume and Issue: 385(6706)

Published: July 18, 2024

Many species, including humans, host communities of symbiotic microbes. There is a vast literature on the ways these microbiomes affect hosts, but here we argue for an increased focus how hosts their microbiomes. Hosts exert control over symbionts through diverse mechanisms, immunity, barrier function, physiological homeostasis, and transit. These mechanisms enable to shape ecology evolution generate natural selection microbial traits that benefit host. Our result from perpetual tension between symbiont evolution, can leverage host's evolved abilities regulate microbiota prevent treat disease. The study will be central our ability both understand manipulate microbiotas better health.

Wrapped Up: The Motility of Polarly Flagellated Bacteria

Annual Review of Microbiology, Journal Year: 2022, Volume and Issue: 76(1), P. 349 - 367

Published: June 2, 2022

A huge number of bacterial species are motile by flagella, which allow them to actively move toward favorable environments and away from hazardous areas conquer new habitats. The general perception flagellum-mediated movement chemotaxis is dominated the Escherichia coli paradigm, with its peritrichous flagellation famous run-and-tumble navigation pattern, has shaped view on how bacteria swim navigate in chemical gradients. However, a significant amount-more likely majority-of exhibit (bi)polar flagellar localization pattern instead lateral flagella. Accordingly, these have evolved very different mechanisms for chemotaxis. Here, we review earlier recent findings various modes motility mediated polar

Symbioses between fungi and bacteria: from mechanisms to impacts on biodiversity

Current Opinion in Microbiology, Journal Year: 2024, Volume and Issue: 80, P. 102496 - 102496

Published: June 13, 2024

Symbiotic interactions between fungi and bacteria range from positive to negative. They are ubiquitous in free-living as well host-associated microbial communities worldwide. Yet, the impact of fungal-bacterial symbioses on organization dynamics is uncertain. There two reasons for this uncertainty: (1) knowledge gaps understanding genetic mechanisms underpinning (2) prevailing interpretations ecological theory that favor antagonistic drivers stabilizing biological despite existence models emphasizing contributions interactions. This review synthesizes information common soil polymicrobial biofilms. The interdomain partnerships considered context relevant community ecology models, which discussed critically.

Gut microbiota, host genetics and phenotypes in aquatic animals: A review

Aquaculture Reports, Journal Year: 2023, Volume and Issue: 31, P. 101648 - 101648

Published: July 7, 2023

In aquatic animals, microbial communities associated with the host exert powerful influences on physiology, reproduction, nutrient metabolism, and phenotypic traits, as well complex behaviors. This relationship between microbes suggests that host-microbiota interactions might have influenced host's genetic variation. To improve our understanding of how hosts interact produce phenotypes, it is necessary to focus animal traits a basis understand potential roles for microbiome in shaping phenotypes. Here, we review literatures environmental effects intestinal community structure, corresponding microbiomes phenotypes breeding. provides better gut microbiota establishes connection factors, while modulating affect differentiation. A more detailed contribute determining role field breeding animals.

Microbial circadian clocks: host-microbe interplay in diel cycles

BMC Microbiology, Journal Year: 2023, Volume and Issue: 23(1)

Published: May 9, 2023

Abstract Background Circadian rhythms, observed across all domains of life, enable organisms to anticipate and prepare for diel changes in environmental conditions. In bacteria, a circadian clock mechanism has only been characterized cyanobacteria date. These clocks regulate cyclical patterns gene expression metabolism which contribute the success their natural environments. The potential impact self-generated rhythms other bacterial microbial populations motivated extensive research identify novel clocks. Main text Daily oscillations community composition function have ocean ecosystems symbioses. are influenced by abiotic factors such as light availability nutrients. some marine symbioses, largely controlled light-dark cycles. gut systems, influx nutrients after host feeding drastically alters microbiota. Conversely, microbiota can influence rhythm variety mechanisms including through interacting with immune system. intricate complex relationship between makes it challenging disentangle behaviors from that might govern daily these populations. Conclusions While ability would likely be enhanced self-sustained rhythm, more evidence further studies needed confirm whether host-associated heterotrophic bacteria possess systems. addition, respond cycles conditions yet uncovered.

Host–gut microbiota interactions shape parasite infections in farmed Atlantic salmon

mSystems, Journal Year: 2024, Volume and Issue: 9(2)

Published: Jan. 31, 2024

Studying host–microbiota interactions through the perspective of hologenome is gaining interest across all life sciences. Intestinal parasite infections are a huge burden on human and animal health; however, there few studies investigating role during infections. We address this gap in largest multi-omics fish microbiota study to date using natural cestode infection farmed Atlantic salmon. find clear association between infection, salmon lifetime growth, perturbation gut microbiota. Furthermore, we provide first evidence that genetic background host may partly determine how changes parasite-associated dysbiosis. Our therefore highlights value hologenomic approach for more in-depth understanding parasitism.

Lighting the way: how the Vibrio fischeri model microbe reveals the complexity of Earth’s “simplest” life forms

Journal of Bacteriology, Journal Year: 2024, Volume and Issue: 206(5)

ABSTRACT Vibrio ( Aliivibrio ) fischeri ’s initial rise to fame derived from its alluring production of blue-green light. Subsequent studies probe the mechanisms underlying this bioluminescence helped field discover phenomenon now known as quorum sensing. Orthologs quorum-sensing regulators (i.e., LuxR and LuxI) originally identified in V. were subsequently uncovered a plethora bacterial species, analogous pathways found yet others. Over past three decades, study microbe has greatly expanded unique role exclusive symbiont light organ Hawaiian bobtail squid, Euprymna scolopes . Buoyed by optically amenable host persistent insightful researchers who have applied novel cross-disciplinary approaches, developed into robust model for microbe-host associations. It contributed our understanding how bacteria experience respond specific, often fluxing environmental conditions which impact development their host. also deepened numerous microbial processes such motility chemotaxis, biofilm formation dispersal, competition, relevance specific genes context colonizing an animal Parallels these between studied pathogens are readily apparent, demonstrating functional conservation across diverse associations permitting reinterpretation “pathogenesis.” Collectively, advances built foundation microbiome positioned continue expand frontiers world inside animals.
