Abstract
The human gut microbiome is a complex and dynamic microbial entity that interacts with the environment and other parts of the body including the brain, heart, liver, and immune system. These multisystem interactions are highly conserved from invertebrates to humans, however the complexity and diversity of human microbiota compositions often yield a context that is unique to each individual. Yet commonalities remain across species, where a healthy gut microbiome will be rich in symbiotic commensal biota while an unhealthy gut microbiota will be experiencing abnormal blooms of pathobiont bacteria. In this review we discuss how omics technologies can be applied in a personalized approach to understand the microbial crosstalk and microbial-host interactions that affect the delicate balance between eubiosis and dysbiosis in an individual gut microbiome. We further highlight the strengths of model organisms in identifying and characterizing these conserved synergistic and/or pathogenic host-microbe interactions. And finally, we touch upon the growing area of personalized therapeutic interventions targeting gut microbiome.

Mollusk microbiota shift during Angiostrongylus cantonensis infection in the freshwater snail Biomphalaria glabrata and the terrestrial slug Phillocaulis soleiformis. Parasitol Res 2020; 119:2495-2503. [PMID: 32556501 DOI: 10.1007/s00436-020-06743-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2019] [Accepted: 06/01/2020] [Indexed: 02/01/2023]
Abstract
In the present work, we reported for the first time the microbiome from Phyllocaulis soleiformis and Biomphalaria glabrata assessed using high-throughput DNA sequencing pre- and post-infection with the helminth parasite Angiostrongylus cantonensis. B. glabrata and P. soleiformis were experimentally infected with A. cantonensis. Fecal DNAs from control and infected groups were extracted and subjected to 16S rRNA high-throughput sequencing survey. No significant differences were found in the alpha diversity indexes in Phyllocaulis and Biomphalaria experiments independently. PCoA analysis using the unweighted UniFrac measures showed that both microbiotas behaved differently depending on the host. In Biomphalaria microbiota, control and infected groups were significantly different (p = 0.0219), while Phyllocaulis samples were not (p = 0.5190). The microbiome of P. soleiformis infected with A. cantonensis showed a significant decrease of Sphingobacterium and a substantial increase of Cellvibrio when compared to a control group. The microbiome of B. glabrata infected with A. cantonensis showed a significant decline in the abundance of Flavobacterium, Fluviicola, Nitrospira, Vogesella and an OTU belonging to the family Comamonadaceae, and a significant increase of Uliginosibacterium and an OTU belonging to the family Weeksellaceae when compared to a control group. Overall, the microbiome data reported here provided valuable information with regard to the diversity of bacterial communities that comprise the gut microbiome of gastropods. Furthermore, we report here the effect of the infection of the helminth A. cantonensis in the ratio and distribution of the fecal microbiome of the snails. Further studies are highly valuable in order to better understand those interactions by comparing different microbiome profiles and mollusk models. By now, we anticipate that ecological studies will take significant advantage of these advances, particularly concerning improving our understanding of helminth-microbiome-host interactions.

Abstract
Host-microbe interactions within the gut are fundamental to all higher organisms. Caenorhabditis elegans has been in use as a surrogate model to understand the conserved mechanisms in host-microbe interactions. Morphological and functional similarities of C. elegans gut with the human have allowed the mechanistic investigation of gut microbes and their effects on metabolism, development, reproduction, behavior, pathogenesis, immune responses and lifespan. Recent reports suggest their suitability for functional investigations of human gut bacteria, such as gut microbiota of healthy and diseased individuals. Our knowledge on the gut microbial diversity of C. elegans in their natural environment and the effect of host genetics on their core gut microbiota is important. Caenorhabditis elegans, as a model, is continuously bridging the gap in our understanding the role of genetics, environment, and dietary factors on physiology of the host.
